Hexagon Area Calculator

Calculate the area of a regular hexagon with six sides of equal length. Includes the formula, a worked example, and honeycomb and bolt-head references.

Calculate area of hexagon

Formula

Regular hexagon:

\\text{area} = \\\\frac{3\\\\sqrt{3}}{2} \\\\times s^2

Where s is the side length.

Approximation:

\\text{area} \\\\approx 2.598 \\\\times s^2

Worked example

Calculate the area of a regular hexagon with side length 8 cm:

\\text{area} = \\\\frac{3\\\\sqrt{3}}{2} \\\\times 8^2 = \\\\frac{3 \\\\times 1.732}{2} \\\\times 64

= 2.598 \\\\times 64 = 166.28 \\\\text{ cm}^2

Result: 166.28 cm²
