How to use this calculator
- Enter the side length.
- Press Calculate.
How it works
Area = (3√3 ÷ 2) × side².
Worked example
2 m side. ≈ 10.39 m².
Common mistakes
- Using the side as the radius — they differ in a hexagon.
- Treating it as six separate triangles without using the triangle area.
Frequently asked questions
How do I find a regular hexagon's area?
Area = (3√3 ÷ 2) × side², about 2.598 × side². A regular hexagon is six equilateral triangles.
Where do hexagons appear in practice?
Bolt heads, nuts, paving and honeycomb — the hexagon tiles a plane efficiently with no gaps.
Does this assume a regular hexagon?
Yes — all six sides and angles equal. For an irregular hexagon, split it into triangles and add their areas.
