We establish the rectifiability of measures satisfying a linear PDE constraint. The obtained rectifiability dimensions are optimal for many usual PDE operators (including all first-order and all second-order operators). Our general theorem provides a new proof of the rectifiability results for functions of bounded variations and functions of bounded deformation. For divergence-free tensors we obtain refinements and new proofs of several known results on the rectifiability of varifolds and defect measures.
