Pauli's exclusion principle has a strong impact on the properties and the behavior of most fermionic quantum systems in both, the micro and macro world. Remarkably, a recent mathematical breakthrough has revealed the existence of further constraints on the one-particle picture emerging from the fermionic exchange symmetry. By exploiting those generalized Pauli constraints we develop a measure which allows one to quantify the influence of the exchange symmetry beyond Pauli's exclusion principle. It is based on a geometric hierarchy of Pauli exclusion principle constraints. We provide a proof of principle by applying our measure to a simple model. The corresponding findings conclusively confirm the physical relevance of the generalized Pauli constraints and show that the fermionic exchange symmetry can have an influence on the one-particle picture beyond Pauli's exclusion principle.
