The perimeter of a regular hexagon is the total length of its outline — the sum of its six equal sides. You use it to figure out how much material you need to go around hexagonal objects like nuts, tiles, or artificial honeycombs.

The Formula

P = 6 × t

• P — perimeter of the hexagon (cm, m, etc.)
• t — side length (all six sides are equal)

In a regular hexagon, the side length equals the radius of the circumscribed circle exactly. This means the perimeter is exactly 6 times that radius — which is why hexagons are often used to approximate circle calculations.
