  We characterize, in the terms of intrinsic Hausdorff measures, the size
of~removable sets for H\"older continuous solutions to elliptic equations with
Musielak-Orlicz growth. In the general case we provide an elegant form of the
measure that captures -- as special cases -- the classical results, slightly
refines the ones provided for problems stated in the variable exponent and
double phase spaces and essentially improves the known one in the Orlicz case.
