Formula Used

The wallet size is calculated using the following formula:

Wallet Length = (Number of Cards × Card Thickness) + (2 × Material Thickness) Wallet Width = Standard Card Width + (2 × Material Thickness) Wallet Depth = Standard Card Height + (2 × Material Thickness)

Where:

Number of Cards = The quantity of credit cards you carry
Card Thickness = Standard thickness of credit cards (0.76mm)
Material Thickness = Thickness of your wallet material (varies by material)
Standard Card Width = 85.60mm (3.37 inches)
Standard Card Height = 53.98mm (2.12 inches)

This formula accounts for the space needed for your cards plus the thickness of the wallet material itself.

Examples

Example 1: Standard Wallet

If you carry 5 credit cards and use a plastic wallet with a material thickness of 0.5mm:

Wallet Length = (5 × 0.76mm) + (2 × 0.5mm) = 3.8mm + 1.0mm = 4.8mm Wallet Width = 85.60mm + (2 × 0.5mm) = 85.60mm + 1.0mm = 86.60mm Wallet Depth = 53.98mm + (2 × 0.5mm) = 53.98mm + 1.0mm = 54.98mm

Recommended wallet size: 4.8mm length, 86.60mm width, 54.98mm depth.

Example 2: Leather Wallet

If you carry 3 credit cards and use a leather wallet with a material thickness of 1.0mm:

Wallet Length = (3 × 0.76mm) + (2 × 1.0mm) = 2.28mm + 2.0mm = 4.28mm Wallet Width = 85.60mm + (2 × 1.0mm) = 85.60mm + 2.0mm = 87.60mm Wallet Depth = 53.98mm + (2 × 1.0mm) = 53.98mm + 2.0mm = 55.98mm

Recommended wallet size: 4.28mm length, 87.60mm width, 55.98mm depth.
