Tips for a better photo collage poster
Resolution decides poster size
At 300 pixels per inch a 3600 px wide file prints sharply at 12 inches; at 150 ppi (fine viewed from a metre away) it covers 24 inches. Each photo needs to be decent too: avoid tiny chat-app copies.
Leave a print margin
Home printers can’t print to the edge. Set Border to 40+ so nothing important is lost, and it also looks like a mounted print.
Print at a shop for big sizes
For anything bigger than A4/Letter, download the PNG and order a poster print. Shops accept JPG or PNG; tell them “fit to page”, not “fill”.
Need words for the post?
Describe what’s in your collage and get five captions to choose from, plus hashtags. Written by AI when you press the button, never before. It only sees the words you type here, never your photos.
Questions
How big can I print a photo collage poster?
The Print export is 3600 px on the short side: 12 inches at 300 ppi, or about 24 inches at 150 ppi, which looks fine on a wall. For A4 portrait that is roughly 3600 × 5091 px.
How many photos fit on a poster?
Up to 25 in the 5 × 5 grid, or 41 in the large heart. For more, use the photo grid maker with up to 10 × 10 cells.
Can I print it on Letter-size paper?
Yes. A4 (1:1.414) and Letter (1:1.294) are close; choose A4 and print with “fit to page” for a thin extra margin on Letter.
