In this paper, we compare James and von Neumann–Jordan constants of normed spaces under certain conditions. It is shown that if a normed space with James constantis three- or more dimensional, or is a-rotation-invariant two-dimensional space, then its von Neumann–Jordan constant is less than or equal to.
