This ratio will be 1 for a circle and greater than 1 for non-circular shapes. Another definition is the inverse of that: Roundness = 4 π × Area See more Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions, such as the cross sectional circles along a cylindrical object such as a See more A single trace covering the full rotation is made and at each equally spaced angle, $${\displaystyle \theta _{i}}$$, a measurement, $${\displaystyle R_{i}}$$, of the radius or distance between the center of rotation and the surface point.
