what size is wallet size

The standard size for a wallet photo is 2.5 x 3.5 inches. This size is considered the industry standard for wallet photos and will fit in most traditional leather wallets with a photo slot. Wallets that are too small or too large may not be able to accommodate this size of photo. It is important to note that wallet-size photos are slightly larger than passport-size photos, which are required to adhere to biometric specifications mandated by the U.S. Department of State.
