How to Print 4 Photos on One A4 Page
Make a 2×2 photo sheet on A4. See the true-size limit, why 10×15 cm prints need slight scaling, and how to export and print the PDF.
Quick answer: use a 2×2 layout
A4 measures 210 × 297 mm. Split it into two columns and two rows and each edge-to-edge slot is 105 × 148.5 mm before printer margins or gaps. A 10 × 15 cm photo is 100 × 150 mm, so four cannot fit at full size in that grid: two 150 mm rows need 300 mm, 3 mm more than the A4 height.
Choose exact size or four copies
If each photo must stay exactly 10 × 15 cm, place two on A4. If four copies matter more, scale each 2:3 photo slightly to fit the printable area; the exact maximum depends on margins and spacing. Keep the original aspect ratio so faces do not look stretched.
Create and print the sheet
Open the 4 Photos / A4 layout, add the images, and check the preview for margins and crop. Export the PDF, select A4 in the printer dialog, then print at 100% or Actual Size. Turn off Fit to Page, which can shrink the whole sheet again.
Why the printed result can still differ
Home printers have non-printable edges, and borderless modes may enlarge a page slightly and crop its edges. Print one test sheet and measure a photo with a ruler before using photo paper or trimming a batch.
Common questions
Can four full-size 10 × 15 cm photos fit on A4? No: two rows of 150 mm need 300 mm, while A4 is 297 mm tall. Will four photos fit if they are smaller? Yes, when each keeps its proportions and is sized for the available printable area.
