An alternative measure of circularity based on the distance Another very common shape factor is the circularity (or isoperimetric quotient), a function of the perimeter P and the area A: $${\displaystyle f_{\text{circ}}={\frac {4\pi A}{P^{2}}}}$$ The circularity of a circle is 1, and much less than one for a starfish footprint.
