Hexagon Gazebo Calculator

The diameter usually refers to the distance from one corner post to the directly opposite corner post, passing through the center. This is also twice the side length in a regular hexagon.

The internal angle of a hexagon is 120°. If you are mitering boards to meet at a corner, the cut angle is half of that: 60°. However, usually, you cut 30° off 90°? It depends on your saw reference. Usually, a 30-degree miter cut works.

A standard hexagon gazebo requires 6 posts, one at each vertex (corner) of the hexagon.

The apothem is the distance from the center of the hexagon to the midpoint of any side. This is crucial for calculating the run of common rafters if you use them, or the span of floor joists.

This calculator displays the "Hip Rafter (Total)" which includes the overhang. The run used for the calculation starts at the center and extends to the post, plus the overhang extension.

A 6/12 pitch is standard for aesthetic balance and drainage. Flatter roofs (4/12) are easier to build, while steeper roofs (8/12+) offer more headroom and a grander look.

Yes, but the math is different. An octagon has 8 sides, and the internal angles are different. This calculator specifically uses the $\sqrt{3}$ relationships unique to hexagons.

Start with a center stake. Use a string cut to the exact length of the "Side Length" (or Radius). Draw a circle. Mark a starting point, then use the same string length to mark 6 equidistant points around the circle circumference.
