Brick Sizing

LEGO bricks follow a precise measurement system that makes every piece compatible. The most iconic piece — the 2×4 brick — is the foundation for all scaling.

Main 2×4 Brick Dimensions

A standard LEGO stud is 8 mm wide. A standard brick height is 9.6 mm (including the studs).

Measurement Value
Width (2 studs) 2 × 8 mm = 16 mm
Length (4 studs) 4 × 8 mm = 32 mm
Height 9.6 mm

How the Logic Scales

All LEGO bricks follow the same simple formula:

This means smaller bricks (like 1×1 or 1×2) and larger bricks (like 2×6 or 2×8) all scale perfectly from the same base unit.

Examples of Other Brick Sizes

Brick Studs Width Length Height
1×1 1 × 1 8 mm 8 mm 9.6 mm
1×2 1 × 2 8 mm 16 mm 9.6 mm
2×3 2 × 3 16 mm 24 mm 9.6 mm
2×4 2 × 4 16 mm 32 mm 9.6 mm
2×6 2 × 6 16 mm 48 mm 9.6 mm
2×8 2 × 8 16 mm 64 mm 9.6 mm

Because everything is based on the same stud grid, LEGO bricks always fit together — no matter the size.
