The proton is something like 100000 times smaller than the orbit of the electron. Both are not usual object, so there are a lot of technical details about how you define the size of each one, but the proton is definitively much smaller than the hydrogen atom.
The electron is inside the proton only a tiny amount of time [1] but it's enough to measure it.
[1] A better explanation should use probabilities and wave functions, but the main idea is that.
