Abstract:	The geometric measure of entanglement of a pure quantum state is defined to be its distance to the space of pure product (separable) states. Given an n-partite system composed of subsystems of dimensions d(1),..., d(n). an upper bound for maximally allowable entanglement is derived in terms of geometric measure of entanglement. This upper bound is characterized exclusively by the dimensions d(1)..... d(n) of composite subsystems. Numerous examples demonstrate that the upper bound appears to be reasonably tight.
