A 4 × 6 inch photograph measures 101.6 × 152.4 mm. With 10 mm margins and a 5 mm gap, two photographs fit on portrait Letter when placed horizontally. This preset starts with two copies of each uploaded image. Set copies to one when you want two different photographs.
How to use the tool
Add JPG, PNG or WebP images, select a thumbnail and set the dimensions. Check paper, orientation, margins and spacing in the preview. Choose the fitting mode and copies, then download the PDF. For two different photos in a two-copy preset, set each image to one copy.
Before you print
Use Actual size or 100% in the PDF print dialog. Match the paper format and disable any further resizing in the printer driver. The preview shows the PDF layout, not a guarantee of your printer’s printable area. Start with ordinary paper and measure before using photo paper.
The 20 mm scale check
The optional control square is 20 × 20 mm. It reserves space at the bottom of every sheet, so enabling it may add a page. Compare both measured sides with 20 mm. For example, a 19 mm side indicates 95% scaling. Do not enlarge the photo to conceal a scaling problem.
