Hexagon Calculator
Calculate the area, perimeter and other properties of a regular hexagon.
The six-sided shape
A regular hexagon has six equal sides and angles, and its properties can all be found from a single measurement like the side length. This calculates a hexagon's area, perimeter and related dimensions.
Enter a hexagon's side length to find its properties.
Why nature loves hexagons
The hexagon is worth a moment's appreciation because it appears so often in nature and design, most famously in honeycomb. There is a mathematical reason: hexagons are the most efficient way to divide a surface into equal regions with the least total boundary, so bees building honeycomb use the least wax to enclose the most space. Hexagons are also one of only three regular shapes that tile a flat surface with no gaps, alongside triangles and squares, and they pack more efficiently than either. This efficiency shows up everywhere from snowflakes to the basalt columns of the Giant's Causeway to graphene's atomic structure. The humble hexagon is nature's answer to covering space economically, which is why it recurs across such wildly different scales.
Frequently asked questions
Why do hexagons appear so often in nature?
They divide a surface into equal regions with the least total boundary, so honeycomb uses the least wax to enclose the most space — an efficiency that recurs across nature.
Do hexagons tile without gaps?
Yes — hexagons are one of only three regular shapes, with triangles and squares, that tile a flat surface with no gaps, and they pack most efficiently.
