Regular Hexagon Area Calculator

About this calculator

This calculator finds the area of a regular hexagon using A = (3√3/2)·s², a formula derived by splitting the hexagon into 6 equilateral triangles radiating from its center — since each triangle has area (√3/4)·s², multiplying by 6 gives the coefficient 3√3/2. Perimeter is simply 6 times the side length.

Geometry students verifying homework, engineers and architects designing hexagonal tiles, honeycomb structures, or paving patterns, and hobbyists working on quilting, woodworking, or board-game design (hex-grid maps) use this. Enter the side length to get the area and perimeter.
