Enter the side length of a regular hexagon into the calculator to determine the radius of the hexagon. The radius is the distance from the center of the hexagon to any of its vertices.

Hexagon Radius Formula

The following formula is used to calculate the radius of a regular hexagon.

R = s / (sqrt(3) / 2)

Variables:

  • R is the radius of the hexagon (units)
  • s is the side length of the hexagon (units)

To calculate the radius of a regular hexagon, divide the side length by the square root of 3 divided by 2.

What is a Hexagon Radius?

The radius of a regular hexagon is the distance from the center of the hexagon to any of its vertices. It is a key measurement in geometry and is used in various applications, including engineering, design, and architecture. The radius helps in determining the size and area of the hexagon and is essential for constructing geometric shapes and patterns.

How to Calculate Hexagon Radius?

The following steps outline how to calculate the radius of a regular hexagon.


  1. First, determine the side length of the hexagon (s) in units.
  2. Next, gather the formula from above = R = s / (sqrt(3) / 2).
  3. Finally, calculate the radius (R) in units.
  4. After inserting the variable and calculating the result, check your answer with the calculator above.
