Why print shops crop your photos
A phone photo is 4:3; a 4×6 print is 3:2; A4 is 1:1.41. When the shapes don't match, the lab trims the long side — often a forehead or a pair of feet. Extending the short side instead keeps the whole picture.
Choose a print size. The canvas is made at 300 pixels per inch (a 4×6 is 1800 × 1200 pixels), the photo is fitted inside and turned to match its own orientation, and the remaining strips are filled. JPG and PNG files are saved with 300 DPI recorded, so print software reads the right physical size.
White border instead?
Choose Colour → Pick → white for a classic border, or set Photo size in the frame below 100% to get an even margin all round.
