The radius of gyration depends upon shape and size of the body, position and configuration of the axis of rotation, and also on the distribution of the mass of the body wrt the axis of rotation.

Radius of gyration is defined as the distance between the center of gravity and the axis about which body is rotating . Generally radius of gyration is denoted by K.
It is given by the formula,
K = √I/m
where,
I = moment of inertia
m = Mass of the body
Radius of Gyration depends upon the following factors:
1) Moment of inertia of the body
2) Mass of the body
3) Shape and size of the body
4) position of the axis of rotation.
