Photo Print Sizes Chart: Inches, Centimeters, and Pixels
Compare common photo print sizes in inches, millimeters, and approximate pixels at 300 PPI, plus the crop differences to check before printing.
Common print sizes at a glance
4 × 6 in = 101.6 × 152.4 mm = about 1200 × 1800 pixels at 300 PPI. 5 × 7 in = 127 × 177.8 mm = about 1500 × 2100 pixels. 8 × 10 in = 203.2 × 254 mm = about 2400 × 3000 pixels. 10 × 15 cm = 100 × 150 mm = about 1181 × 1772 pixels. 13 × 18 cm = 130 × 180 mm = about 1535 × 2126 pixels. Pixel counts are rounded targets, not minimums guaranteed to look sharp.
What PPI tells you
PPI is the image-pixel density at the final print dimensions. To estimate a pixel target, multiply each side in inches by the desired PPI; for example, 4 inches × 300 gives 1200 pixels. A higher PPI does not add detail that is missing from the original image, and a lower-resolution image can look fine when viewed from farther away.
Match the photo shape to the paper
A 4 × 6 print has a 2:3 shape, as does 10 × 15 cm. A 5 × 7 print has a 5:7 shape, and 8 × 10 has a 4:5 shape. When the image and print ratios differ, choose Fit to keep the whole photo with possible blank space, or Fill to cover the paper with some cropping.
Print at the measured size
Set the requested physical dimensions in the layout, export a PDF for the matching paper, and print at 100% or Actual Size. Check that paper size in the dialog matches the PDF and turn off Fit to Page. Measure one test print if the size must fit a frame or template closely.
Are 10×15 cm and 4×6 inches identical?
No. 10 × 15 cm is 100 × 150 mm; 4 × 6 inches is 101.6 × 152.4 mm. Both have a 2:3 aspect ratio, so their proportions match even though the physical dimensions differ slightly.
