Photo printed at Profotonet

Having a photo printed starts with one important choice: the size. Do you go for a classic 13x18 for a frame, a 30x40 as an eye-catcher on the wall, or a photo in poster format? In this blog, we list all photo sizes for you, explain exactly how the measurements work, and help you choose the size that best suits your photo and your wall.

The Most Popular Photo Sizes at a Glance

Photo sizes are indicated in centimetres: first the short side, then the long side. Printing a photo in 20x25 therefore means a print of 20 by 25 centimetres. These are the most popular sizes and what they're best suited for:

SizeIdeal for
10x1510x15The classic photo size: albums, photo boxes, perfect for giving away
13x1813x18Slightly larger than standard, ideal for frames on a desk or sideboard
15x2015x20Portraits and frame sizes, widely used by photographers
20x3020x30The boundary between small and large: perfect as your first piece of wall decor
30x4030x40A true wall format, beautiful in a photo frame or as a series
60x80, 60x90 and larger60x80, 60x90 and largerPoster format for maximum impact, up to an impressive 120x180

Torn between two sizes? Then choose the larger one. A photo on the wall quickly looks smaller from a distance than you might think, a common misjudgement when designing a photo wall.

Good to know: photo paper was traditionally measured in inches. We convert those measurements to whole centimetres, which means the actual size of your print may differ slightly. A 10x15, for example, actually measures 10.1 x 15.2 cm.

Printing Photos in A4 or A3: How Does That Work?

Many people search for a photo print in A4, because this paper size is so familiar. But be aware: A sizes and photo sizes are not the same. An A4 measures 21 x 29.7 cm and an A3 measures 29.7 x 42 cm – slightly different from the photo sizes 20x30 and 30x40.

If you want to print an A4 photo, choose the photo size 20x30: the difference of a few millimetres disappears completely in a frame with a passe-partout. For an A3 photo print, 30x40 is the logical choice.

Why Your Photo Doesn't Always Fit Perfectly: Aspect Ratio

The size of your print doesn't just depend on the paper, but also on the ratio in which you shoot. A DSLR or mirrorless camera usually shoots in 2:3, while a compact camera or smartphone often shoots in 3:4. That ratio determines which photo sizes fit seamlessly:

  • 2:3 fits perfectly on 10x15, 20x30, 40x60 and 60x90
  • 3:4 fits perfectly on 15x20, 30x40 and 60x80
  • 1:1 (square) calls for square sizes such as 20x20, 40x40 or 50x50

Doesn't your photo's ratio match the chosen print size? Then you can set the crop yourself in the designer. That way, you decide which part of the photo ends up on the print.

Printing Large Photos: From 30x40 to Poster Format

Printing a large photo is the way to turn a special image into genuine wall art. From 30x40 onwards, we speak of large format. If you want a photo as a poster on the wall, the 60x40 format is large enough to carry the space without claiming an entire wall.

If you want to order photo posters for maximum impact, we offer sizes up to an impressive 120x180 cm. All large formats are photochemically exposed on professional Fujifilm paper or printed on museum-quality Fine Art paper, such as Hahnemühle. This way, even an enlargement in poster format gets the sharpness and colour depth you expect from a photo print – a fundamental difference compared to a standard printed poster.

Printing Photos in Small Formats

There's plenty to choose from at the other end of the spectrum too. Printing a photo in a small format (think 10x15 or 13x18) is perfect for photo albums, keepsake boxes or giving away. Small square prints such as 20x20 have a modern, Instagram-style look and are ideal for a playful photo wall with several images side by side.

How to Choose the Right Size: Three Rules of Thumb

  1. Look at the location, not just the photo. Measure the wall or frame and take viewing distance into account: the further away you stand, the larger the format can be.
  2. Let your photo's aspect ratio lead the way. A 2:3 image looks its best on 20x30, 40x60 or 60x90 – that way you use the full paper without compromise.
