Landscape 45×35 mm
At 300 DPI, 45×35 mm is 531 × 413 pixels, wider than tall.
Passport photo? Passport photos are upright: 35 mm wide × 45 mm tall. Some forms write the height first, which is why people search for 45×35. For a portrait photo use 3.5×4.5 cm.
Landscape uses include small labels, document thumbnails and postage-style images.
Millimetres suit precise jobs. Label printers, stamp makers and die cutters usually work in millimetres, and their templates often allow a tolerance of only a millimetre or two. Print a test page at 100% scale and measure it before running a batch.
Same size in centimetres: 4.5×3.5 cm.
