Question 1

What side length gives a hexagon area of 100?

Accepted Answer

s = sqrt(2 x 100 / (3 x 1.7321)) = sqrt(200 / 5.1963) = sqrt(38.49) = 6.20. A regular hexagon with side 6.20 has area approximately 100 square units.

Question 2

How do I find the side from perimeter?

Accepted Answer

Divide the perimeter by 6. A regular hexagon with perimeter 42 has side = 42 / 6 = 7. This works because all six sides of a regular hexagon are equal.

Question 3

What if I enter both area and perimeter?

Accepted Answer

The calculator computes side from both inputs and uses the area-derived value as the primary result. If the hexagon is truly regular, both methods should give the same answer. A discrepancy indicates measurement error or a non-regular hexagon.

Question 4

How do I convert a hex bolt "across flats" measurement to side length?

Accepted Answer

The "across flats" dimension of a hex bolt equals 2 x apothem = s x sqrt(3). So side = across-flats / sqrt(3) = across-flats / 1.7321. A 19mm hex bolt has side = 19 / 1.7321 = 10.97 mm.

Question 5

Is this calculator only for regular hexagons?

Accepted Answer

Yes. The formulas assume all six sides are equal and all six angles are 120 degrees. Irregular hexagons have no single "side length" and require different methods to analyze.
