Photo Print Layout – Several Photos on One Page

Printing one small photo per sheet wastes paper and money. This layout tool places as many prints as fit on A4, Letter or photo paper, in wallet, passport, ID or postcard sizes, and writes a PDF in which every photo has its exact size in millimetres. It picks the paper orientation that fits the most prints, adds cut marks for a paper cutter, and runs entirely in your browser.

How to use this tool

1. Choose your photos, and whether to fill the page with one photo, place each photo once, or print several copies of each.
2. Pick the paper and the print size, or enter a custom size in millimetres.
3. Choose "fill the print" (crops the edges) or "show the whole photo", and set the margin and the gap.
4. Download the PDF and print it at 100% / actual size, then cut along the marks.

Formula

prints across = ⌊(paper width − 2 × margin + gap) ÷ (print width + gap)⌋, prints down likewise with heights; prints per page = across × down

Both paper orientations and turning the prints sideways are tried, and the layout with the most prints wins (upright prints first if there is a tie). The grid is centred on the page. Each print is rendered at 300 dpi and placed in the PDF at its exact millimetre size. Cut marks are short lines in the margin, in line with every print edge.

Example

Wallet prints are 2.5 × 3.5 in (63.5 × 88.9 mm). On Letter paper with a 5 mm margin and a 3 mm gap, portrait paper fits ⌊208.9 ÷ 66.5⌋ = 3 across and ⌊272.4 ÷ 91.9⌋ = 2 down = 6. Landscape fits ⌊272.4 ÷ 66.5⌋ = 4 × ⌊208.9 ÷ 91.9⌋ = 2 = 8 per page, so landscape is used.
