Standard photo sizes

What is dpi

DPI is a characteristic of a printing device; it shows how many dots per inch a given device can print. 300Dpi is considered sufficient. But the fact is that in a captured digital photograph there may not be enough pixels for a given print area. Let’s calculate whether it is possible to stretch our photo to an area of ​​10 by 15 centimeters.

Why it is important to consider standard photo sizes

In the vast majority of cases, the digital photographs you receive will be printed on photo paper of standard sizes. If the proportions of digital photographs and the selected photo paper sizes do not match, the photographs may come out stretched, not clear, lose image quality, and have other undesirable consequences for you.

Therefore, it is important to compare the standard photo sizes for printing and the pixel sizes of the digital photos you have to choose the optimal printing format.

10 tricks for perfect photos

Do you like photography? Then this article is for you. In it you will find 10 simple photography techniques that will improve the quality of your photos.

The outstanding French photographer Henri Cartier-Bresson said: “The lot of a photographer is constantly disappearing things. And when they leave, no amount of ingenuity, nothing in the world will make them come back.” In order not to miss “disappearing things”, you need to hone your skills. Here are some tips to help you.

11 questions about digital photo printing (part one)

Envelopes with printed photographs.

Digital photography allows you to view the results of your shooting directly on your computer, so today we print much less often than in film days. However, precisely because of the “exclusivity” of the task, the requirements for the quality of hard copies also increase: having spent time selecting and processing the best photographs, we expect to see an equally high-quality result on paper.

White Balance

If you shoot in RAW, you can adjust the white balance later. But if you want to use JPEG images right away and at the same time photograph in artificial or mixed light, then it is better to set the white balance manually.

Specific settings vary depending on the camera model. But the principle is the same.

Custom white balance can also be used to emphasize color tones in a photo. Use the technique described above, but the standard should not be colorless, but colored. For example, cold blue. It will give the frame a warm yellowish tint – what is needed for shooting the haze of dawn.

What is the difference between 10 x 15 and 11 x 15?###

Initially, print formats were designed for the most common frame formats. At the dawn of the film era, most amateur cameras shot with 135-type film in a 24 x 36 mm frame format. The aspect ratio of such a frame is 2:3 – it was for this that print formats 10 x 15, 20 x 30, 30 x 45, etc. were created

With the advent of digital cameras, manufacturers began to focus on the format of computer monitors, which in most cases is close to the 3:4 aspect ratio. Today, both types of cameras are common: * with an aspect ratio of 2:

If you print a 3:4 frame in a 10 x 15 format, a significant portion of the image will either be left out of print or wide white margins will appear on the image (depending on the print mode). To eliminate this misunderstanding, photo laboratories began to actively offer clients a new print format – 11 x 15, the aspect ratio of which is close to 3:4. Today it has already become standard – photo albums, frames, envelopes, boxes, and various accessories are made for it.

If you print photographs without preliminary cropping, then to select the most optimal print formats you need to find out (calculate) the aspect ratio of the frame in your camera.

Below are some common print formats based on aspect ratios:

Frame aspect ratio 2:3 Aspect ratio 3:4
10 x 15 cm 11 x 15 cm
15 x 20 cm 15 x 22 cm
30 x 45 cm 30 x 40 cm


Many people are afraid to use a flash, whether built-in or external. But once you become friends with her, the quality of your photos will increase significantly.

The “bounce” flash built into the camera is often ridiculed. External flash really gives better results. But the built-in one can also be used to add sparkle to the eyes or highlight shadows.

Using the flash is easy. There are many external flashes that work with the camera’s built-in metering system to produce balanced exposures.

Once you start using flash, you’ll soon be enjoying fiddling with it and experimenting with manual controls. Flash is a great tool for everyday photography, not just for special occasions. Just try it!

Hyperfocal distance

Another concept associated with depth of field is hyperfocal focusing distance. You’ve probably seen landscapes where the background and foreground are equally sharp. To achieve this in your photos, you need to learn how to use hyperfocal distance.

Simply put, this is the same depth of field, but when focusing at infinity. Like depth of field, hyperfocal distance depends on the focal length of the lens and aperture. The smaller the aperture and focal length to the subject, the smaller it is.

There are apps that help you determine hyperfocal distance and depth of field. They will tell you the ideal focal length, the distance to the subject, and the aperture.

Depth of field

This is the range of distances at which objects appear sharp in the frame. This is one of the key parameters of photography, which, among other things, can cause a blurry picture.

A wide aperture (F/2.8) results in a shallow depth of field. Conversely, a smaller aperture (for example, F/16) increases the area of ​​focus.

You can also control the depth of field using the focal length and the distance to the subject. The closer to the subject you shoot or the longer the lens you use, the shallower the depth of field – only a narrow strip of the image will be in focus. And vice versa.

Therefore, when choosing a lens for shooting, think about how it will affect the depth of field. If necessary, adjust the aperture and/or distance to the subject being photographed.

Ready-made templates

1. Save the picture with the desired size: left-click on the picture – click save image/picture.

2. Open the downloaded image in any photo editor (for example, Photoshop or Paint) and paste your photo on top.

3. Done! Can be printed.

Why do you need to know the size of photos to print?

Previously, when we photographed our holidays and birthdays using “film” cameras, we took the “tube” of film to a special workshop. There we marked the selected frames that needed to be printed, and then picked up the finished order. And already at home they often discovered that the photos turned out unsuccessful. It was almost impossible to see them on film.

Now, in the era of digital photography, it would seem that everything is much simpler, and before taking a flash drive with pictures to print, we can thoroughly study them and select the best ones. But, in fact, only those who have never printed frames from digital media think so.

The problem here is that such pictures can have any extension, as well as the ratio of horizontal and vertical sizes. In turn, photo paper is produced within certain standard parameters. And if, for example, you take a wonderful square frame to a photo workshop, then when printing, the master will, at his discretion, “cut off” part of the photo in order to adapt it to the desired rectangular format. And it’s not a fact that you will like how he did it.

It is in order to avoid such troubles that you need to know the exact dimensions of the photographs, as well as how many horizontal and vertical pixels correspond to them.

You can get the necessary information by reading the special table provided above.

Bleed frame or whole frame – how to set the print mode?###

Since in general any file has arbitrary dimensions (arbitrary aspect ratios), when printing it in any standard format, the question always arises of how to crop it. Mathematically, there are only three options for placing a picture on the final print.

Let’s consider the operation of these modes in more detail.

How to edit pictures?

You can easily edit your photos, change their frame and size in the Paint program, which is available on any computer. This graphic editor is easy to use and very convenient even for inexperienced users.

To process a photo, you must first right-click on the desired file, then select “open with” from the menu, and then click on “Paint”.

When the desired photo opens on your monitor, select the “resize” button in the upper right corner. The program will offer two options, one in percentage and the other in pixels, here you need to select the second one. After this, all you have to do is enter the necessary parameters and save the changes.

As a result, it turns out that in order for you to be completely satisfied with the resulting paper photographs, you need not only to select the best frames, but also to process them correctly, “adapting” them to the standard sizes of sheets of photographic paper.

What methods of printing photos are there?###

The most common technologies today: * photo printing in a chemical process; * inkjet printing.

In the first case, the picture is projected in the dark onto photographic paper; Then the print goes into a chemical process – developing, bleaching, fixing, washing. Everything is like the good old days, right down to the drying. Only now there are no glossers, and the reflective properties of surfaces are implemented in the materials themselves – these are matte, glossy, embossed paper, as well as metallic coated paper (metallic), translucent film (duratrans), etc.

Non-standard photo formats for printing

There is a group of non-standard formats, for example square, which are becoming increasingly in demand today, due to the popularity of the social network social network. The most prominent example is images taken with Instax instant cameras.

Review of popular photo formats for printing

There are generally accepted international ISO formats that define standard sizes for photographic paper. However, terms such as A3, A4, Whatman paper, etc. have become more familiar to us. The aspect ratio of the main photo formats is similar to the matrices of modern digital cameras and is 1: 1.5 (2/3) or 1: 1.33 (3/4), and standard international paper sizes are 1: 1.4142.

We invite you to familiarize yourself with the table, which shows the main photo formats for printing.

Основные форматы фото для печати

Let’s take a closer look at the main options and compare them with standard ISO formats.

Соотношение формата A4 и фото 10х15

One of the most popular photo formats for printing is 10×15. It differs from the standard A6 in that it is 2 mm smaller on one side and 5 mm larger on the other. This is perhaps the most common format and is suitable for almost all photo albums and frames. The photo shows how the 10×15 image compares to A4 photo paper.

Соотношение формата A4 и фото 15х21

An equally popular photo size for printing is 15×21. The photo is slightly larger than A5. The difference is very small: on one side the difference is 5 mm, on the other – 1 mm. Vertical photographs are ideal for creating portraits.

Соотношение формата A4 и фото 20х30

The photo format for printing 20×30 is close to A4, the difference is that on one side the image is 6 mm smaller, on the other – 9 mm larger. The peculiarity of photographs of this size is their high detail and clarity. That is why images are often used to create posters, which are an excellent interior decoration.

Соотношение формата A3 и фото 30х40

Using a 30×40 photo for printing is an excellent option for creating a highly artistic wall composition. The difference between the format and A3 is that on one side and the other the image is larger by 9 mm and 1 mm, respectively. Photographs are often placed in a wooden frame or stretched on a stretcher.

Соотношение формата A3 и фото 30х45

Photo format for printing 30×45 is one of the favorites among users of the Mimigram application. This size is ideal for making posters
. The printed images are incredibly clear and colorful. That is why posters are often used to organize photo exhibitions. The format is slightly larger than standard A3.

Where did the formats come from

And although anything can be printed, there are the most popular sizes for which frames are produced. Where did these sizes come from? They are related to camera sensor formats and common paper sizes.

Popular photo sizes for printing with format table

The generally accepted standard photo is 10 by 15 cm in size. However, the size of a commensurate digital photo is usually slightly larger (for example, 10.2 by 15.2 cm), and the pixel size of this photo will be 1205 by 1795 pixels.

Other formats are shown in the table below:

Standard photo sizes

If you plan to work with large-format printing, then it has quite broad requirements for digital images:

Standard photo sizes

If you know the dpi parameter and the number of pixels of your photo, then using the formula below, you can calculate the required dimensions of the sides of your photo:

In this formula:

x – the required size of one side of the photograph in centimeters; r – photo side resolution in pixels; d – 2.54 cm (standard inch); dpi – usually 300 (less often – 150). For example, let the image width be 1772 pixels and dpi=300. Then 1772*2.54/300=15.00 cm in print width.

Rule of Thirds

This is a compositional technique invented at the end of the 18th century and originally used in painting.

According to the laws of perception, a person cannot maintain attention on the entire picture at once. “Attention Knot” catches the eye and forces the viewer to concentrate. Therefore, the rule of thirds not only streamlines the composition, but also simplifies perception.

The viewfinders of many modern cameras are equipped with a grid based on the rule of thirds. In this case, all you need to do (for example, when shooting landscapes) is to make sure that the horizon is parallel to the horizontal grid line, and the key objects (trees, mountain, etc.) are at the intersection of the thirds.

The rule of thirds is simple and quite universal (even suitable for portraits). But don’t get carried away. There are shots where the subject just begs to be in the center; and sometimes it is better to place it at the edge.

Arranging a composition is one of the components of the photographic process. It should be thought through in advance. But if you don’t have time or ideas, then feel free to use the rule of thirds.

Convert centimeters to pixels taking into account dpi

Let’s say we want to print a photo 10 by 15 centimeters (actually a little more, taking into account the width of the roll – 10.2 cm by 15.2 cm).

1 cm=0.393701 inches. 300 pixels are printed per inch.

Multiply, it turns out that

10.2 * 0.393701 * 300 = 1205 points (i.e. pixels) required in height.

And the width required:

15.2 * 0.393701 * 300 = 1795 pixels.

That is, our size:

1205 to 1795, which is what is written in the right column.

You can quickly calculate the required number of pixels using a calculator here.

Just remember to immediately select centimeters, not inches. And there you can also select Dpi, we have 300:

Calculate pixels from centimeters

That is, our photo must be at least 1205 by 1795 pixels in size (more is possible).

Size in pixels and size in centimeters

It is useless to guess what size in pixels your photo should be without taking into account Dpi. If the photo is artistic and quality is important, you can find out the DPI of the printer in the darkroom.

Photo sizes for printing, format table with examples

Many of us love photography. The variety and availability of digital cameras make photography a popular pleasure, allowing us to capture the bright, colorful moments of our lives. At the same time, the high quality of the resulting photographs does not at all guarantee the same quality when printing digital photographs on standard roll photo paper.

Modes for automatically cropping photos when printing

  1. When printing photographs, it is common to crop the photos because the print size does not always match the original frame size. For example, if the aspect ratio of your camera’s matrix is ​​3:4, and you ordered a 10×15 print (aspect ratio 2:3), then a small cropping of the image inevitably occurs during printing.
    When an order is received, the print operator looks at the image, and if important elements of the photo fall into the cropping zones, a decision is made to crop manually to avoid cutting off important elements of the photo. In other situations, cropping is done automatically when printing.
    Standard photo sizes

    In the figure, dark stripes indicate parts of the frame that will be cropped during printing.

The photo was taken with a Canon PowerShot G5 digital camera, image size 2592×1944 pixels. A 10×15 print with a print resolution of 300 dpi has a size of 1795×1205 pixels. Accordingly, if the original image was not previously brought to the required size, then the print will only produce a fragment of the image relative to the center.
Standard photo sizes

The light area in the photo is the part that will appear on the print. The area highlighted in dark will be cropped.

Frame aspect ratio

Usually photos look good at their native aspect ratio (usually 2:3 or 4:3). But an alternative ratio can have an unexpected effect and significantly improve the picture.

Instead of leaving thinking about the aspect ratio and playing with crop to post-processing, it is better to take a closer look at the subject of the photo and decide which aspect ratio is suitable at the shooting stage.

Many cameras allow you to set the aspect ratio right in the camera, but if you shoot RAW and JPEG at the same time, you will still have the source to crop during editing.

The main advantage of this is that you will see the picture in the selected aspect ratio and move the camera or subject to improve the composition.

It is not recommended to crop images arbitrarily; when cropping, it is also better to maintain a certain aspect ratio.

Gradually you will learn to see which aspect ratio best emphasizes the composition.

Camera sensor aspect ratio

The fact is that camera matrices most often have a 3:2 or 4:3 format (the ratio of width to height, 3:2 is more common). Straight out of the camera, without processing, the image most often has the following aspect ratio:

Although it can be edited in a photo editor, including cropping, so that the aspect ratio changes.

  • Standard color correction
  • When printing photographic images, the color scheme of the photograph is corrected. When correcting, several basic principles are used:
  • If people are the main subject of the photograph, adjustments are made to achieve the most correct skin tone possible, but the overall color scheme may change and some colors may not appear accurately.

  • When correcting landscapes, the basis is the correct display of the greenery of plants, or the color of the sky, if the main content of the image is the sky. For winter landscapes, the basis is to obtain the whiteness of the snow.

    If you want to color correct your photographs yourself, when ordering you must specify the option “without correction”, but you must remember that the image you see on your monitor may not match the print due to inconsistency in color reproduction characteristics Your monitor and printing machine.

    3. Our professional equipment makes it possible to process and edit files only with the JPG extension; other formats are not accepted. In order for the image in the photo to be contrasty and clear, the resolution must vary from 72 to 300 dpi, in other words, the quality of the print depends on the number of dots per inch.
    4. The size of the photo matters; sometimes a minimum number of pixels is enough, but for large-format printing of large sizes (a1, a2, a3) the optimal number is required. The sizes and formats of photo printing do not always correspond to the frame format in a digital camera, therefore, in order to avoid cropping the main elements of the overall plot, you should take into account the aspect ratios.

        When placing an order, the print operator previews the image and, if necessary, makes crops manually. For the convenience of consumers, on our website the sizes and formats for printing photographs are presented in table form. The standard format is a clearly defined linear dimension.

        1. Spot Metering
      5. Exposure metering is a measure of the brightness of an image based on the amount of light entering the camera. It allows you to avoid darkening or brightening your photos. There are three types of exposure metering: center-weighted, matrix and spot.

        With spot metering, brightness is usually determined at the center of the frame or at the active focus point. Spot metering is used when the brightness of the subject is very different from the brightness of the background, and also when there are very light or very dark objects in the frame.

        Spot metering is typically used to take photographs with the main subject properly exposed. The brightness of other objects is ignored.

        The more you use spot metering, the more you will understand about exposure.

        Format in pixels

        There is no unambiguous answer as to how many pixels there are in a given size of sheet of format A, just as there is no unambiguous answer as to how many pixels there are in a centimeter. Depends on screen resolution. At different resolutions – different numbers of dots per inch (PPI/DPI parameter). We will provide sheet sizes for popular resolutions.

        Format a in centimeters and inches

        Format Size (width × height)
        mm cm inches
        A0 841 × 1189 84.1 × 118.9 33.1 × 46.8
        A1 594 × 841 95.4 × 84.1 23.4 × 33.1
        A2 420 × 594 42.0 × 59.4 16.5 × 23.4
        A3 297 × 420 29.7 × 42.0 11.7 × 16.5
        A4 210 × 297 21.0 × 29.7 8.3 × 11.7
        A5 148 × 210 14.8 × 21.0 5.8 × 8.3
        A6 105 × 148 10.5 × 14.8 4.1 × 5.8
        A7 74 × 105 7.4 × 10.5 2.9 × 4.1
        A8 52 × 74 5.2 × 7.4 2.0 × 2.9
        A9 37 × 52 3.7 × 5.2 1.5 × 2.0
        A10 26 × 37 2.6 × 3.7 1.0 × 1.5

        The ISO 216 standard defines the following requirements for format A:

        • The height to width ratio is 1.4142 (√2);
        • The size of the A0 sheet is equal to the area of ​​1 square. m;
        • Each size A(n) is half of A(n-1);
        • The height and width of each size are rounded to the nearest millimeter.

        Purposes for printing a photograph and standard sizes of photographs for printing in cm

        We recommend choosing a format taking into account the purpose for which you need the image:

        • Eternal classic – 10×15 cm. This picture will fit in any family album and frame, people with average vision can easily see it, in a small room an image of 10×15 cm will look good on the wall as a solo , and next to others.
        • A4 (translated onto photographic paper – 20×30 cm) should be ordered for wall decoration. Both in a commercial interior and in a spacious room, the photo will look representative and bright.
        • 30×40 and 40×50 cm – large images that should preferably be viewed from a distance. Typically, these sizes are chosen for interior design with an emphasis on decor. A resolution of 300 dpi, typical for small photographs, is not enough in this case: a large picture is visible to everyone at once, so it must be clear and free of “noise,” so it’s worth taking care of shooting with a modern digital camera.
        • Printing portraits for documents involves using photo sizes for printing in cm. So, for a passport you will need a portrait of 3.7×4.7 cm, for issuing an ID – 3×4 cm, for obtaining a visa – 3.5×4 .5 cm, for a standard pass – 6×9 cm.

        Choose the paper correctly so you don’t have to worry about fitting a photo with wide white margins and don’t have to think about how to get back that part of the image that didn’t fit. All printing houses, photo shops and websites usually provide format tables. You can also ask an employee for help through feedback on the website, by phone, or by contacting him personally upon arrival at the studio. Go to services page


        This article provided standard photo sizes for printing, popular photo formats, as well as a convenient formula for calculating the optimal size of the sides of a photo. I recommend sticking to the formats I have given, this guarantees the quality of the printed photographs, and therefore the visual pleasure of viewing them.
