What are the standard photo print sizes?
The Printer Working Group lists these among its standard media names: 3.5 x 5, 4 x 4, 4 x 6, 5 x 5, 5 x 7, 8 x 10, 8 x 12, 10 x 12, 10 x 15, 11 x 14, 12 x 15, 12 x 16, 14 x 18, 16 x 20, 18 x 22, 20 x 24, 22 x 28, 24 x 30 and 30 x 40 inches. Individual labs offer their own subset and may add metric sizes.
Each print size has its own aspect ratio, so a photo rarely fits without a crop. A 3:2 photo suits 4 x 6, 8 x 12 and 10 x 15 exactly; 5 x 7 and 8 x 10 crop it by a little more.
Frequently asked questions
What size is a 4x6 photo in cm?
10.16 x 15.24 cm (101.6 x 152.4 mm).
What size is 8x10 in cm?
20.32 x 25.4 cm. The nearest ISO size is A4 (21 x 29.7 cm), which has a different shape.
How many pixels do I need for an 8x10 print?
At 300 DPI, 2400 x 3000 pixels. Change the DPI above to see other resolutions.
Which print sizes have the same shape as my camera photo?
Work out your photo ratio from its pixel size: 6000 x 4000 is 3:2 and 4000 x 3000 is 4:3. 4x6, 8x12 and 10x15 are 3:2. Find your ratio in the crop columns, where 0% is an exact match.
Are these official sizes?
They are the names listed in the Printer Working Group standard. Labs choose which they stock, so confirm with yours.

Checked
Sizes are from PWG 5101.1-2023 Tables 3 and 4 (index and photo media sizes). Pixels, millimetres and crop percentages are calculated; 25.4 mm per inch. Runs entirely in your browser. Nothing you type is sent or stored.
Scope
Sizes and results are arithmetic on published paper sizes and the numbers you enter. Printers and print shops set their own sizes, margins, bleed and resolution requirements, so confirm with yours before you print.
