Standardized photograph sizing does not exist, but common sizes for personal photograph prints include 4x6, 5x7, 8x8, and 8x10 inches. Common portrait sizes include 8.5x11, 9x16, 11x14 and 11x16 inches. Typical measurements for large photograph prints are 16x20, 20x30 and 22x32 inches.
Other common photograph print sizes include 10x13, 10x20, 20x24 and 22x32 inches. Examples of common specialty photograph print sizes include 12x18, 24x36 and 11x11 inches.
While no set sizing standard exists for photographs, photos are usually sized to fit picture frames or mat boards. Unlike photographs, picture frame sizing is standardized. This results in similar photograph measurements which creates the illusion of standardized sizes.
