Regular Heptagon Apothem Calculator

This tool works well for focused work where you only want one formula and one answer path around regular heptagon apothem.

Important Use Notice

Informational calculator only. Verify important outputs independently before legal, tax, medical, engineering, safety-critical, contractual, employment, or compliance use.

Estimate

Enter job values, review the estimate, then use the decision hints before ordering or quoting.

Estimate Results

Check

Forgetting that some inputs must be whole-number counts rather than decimals.
Mixing units across the inputs before reading the result.

Example

Side Length 6 gives Apothem 6. 2296.

Formula

apothem = side / (2 x tan(pi / 7))

Use the central triangle inside a regular heptagon to move from side length to the apothem.

Only regular polygons fit this shortcut.
