The Octagon Side Length in a Square calculator computes the sides of length (s) of a regular octagon that would fit in a box (square).
INSTRUCTIONS: Choose units and enter the following:
Octagon Side Length (s): The calculator returns the side length (s) in meters. However, this can be automatically converted to other length units (e.g. feet) via the pull-down menu.
A regular octagon is an eight sided polygon where all of the lengths of the sides and the interior angles are the same. Octagon shapes are used in many application and even in nature. Octagon shapes provide conveniences of straight sides with the general appearance of a more circular polygon.
The formula for the length of a side of a regular octagon that fits in a box is:
`s = w / (1 + sqrt(2))`
s - side length
w - width of the square
