The role of fermionic matter in the spectrum of the area operator is analysed using the Baez - Krasnov framework for quantum fermions and gravity. The result is that the fermionic contribution to the area of a surface S is equivalent to the contribution of purely gravitational spin network's edges tangent to S . Therefore, the spectrum of the area operator is the same as in the pure gravity case.
