A standard wallet size photo typically measures 2 inches by 3 inches (5.08 cm by 7.62 cm)**. This size is the most common and is designed to fit into the photo slot of a standard wallet, purse, or photo album plastic sheet. The photo can be oriented either horizontally (2" high x 3" wide) or vertically (3" high x 2" wide), maintaining the same aspect ratio of 2:3

. While 2x3 inches is the standard size in the United States, some variations exist, with other common sizes ranging from slightly smaller than 2x3 inches up to about 2.5 x 3.5 inches, depending on the wallet style or printing service

. In summary:

• Standard wallet photo size: 2" x 3" (5.08 cm x 7.62 cm)
• Alternative sizes: up to about 2.5" x 3.5" (common in some photo prints)
• Fits most traditional wallet photo slots and is smaller than credit card or passport photo sizes

This size is compact enough to carry a small personal photo of loved ones or pets conveniently in your wallet.
