How the numbers are calculated
Multiply each physical edge in inches by the target DPI. An 8 inch edge at 300 DPI requires 2400 pixels. A 10 inch edge requires 3000 pixels.
Account for crop and bleed
The table lists finished image dimensions. Commercial layouts may need bleed beyond the trim edge. Photo labs may also crop a small percentage because of printer tolerances. Keep essential details away from the border.
Check your own file
The photo print size calculator compares one image against all common sizes and reports its effective DPI. Use the DPI checker when you also need metadata and file details.
Frequently asked questions
How many pixels are needed for a 4 × 6 photo?
Use 1200 × 1800 pixels for 300 DPI or 960 × 1440 pixels for 240 DPI.
What size is 3000 × 2400 pixels?
It is 10 × 8 inches at 300 DPI, 12.5 × 10 inches at 240 DPI, or 20 × 16 inches at 150 DPI.
Why does an 8 × 10 crop my camera photo?
Most cameras capture 3:2 or 4:3, while 8 × 10 is 4:5. Those proportions do not match, so cropping or borders are required.
