Hexagon Calculator

Calculate area and perimeter of a regular hexagon.

Side Length

Enter a side length above.

How to Use the Hexagon Calculator

Enter the side length of a regular hexagon to calculate its perimeter and area.

Practical Example

For a side length of 5, the perimeter is 30 units and the area is approximately 64.95 square units.

Factors That Affect the Result

The formulas assume all six sides and interior angles form a regular hexagon. Irregular hexagons require different measurements.

Frequently Asked Questions

Does this work for irregular hexagons?

No. It is designed for regular hexagons.

How is perimeter calculated?

Multiply the side length by six.

What units can I use?

Any consistent length unit can be used.

Working with Regular Hexagons

For a regular hexagon, all six sides are equal. Perimeter is 6s and area is (3√3/2)s². A regular hexagon can also be divided into six equilateral triangles, which helps explain the area formula.

These formulas do not apply directly to irregular six-sided shapes. Confirm whether the input is side length, apothem or another measurement, and use consistent units. For fabrication or layout work, account separately for kerf, borders or material tolerances after calculating the ideal geometry.
