Which subatomic particle is smaller: Neutron or Proton?

I already told you the Neurton is smaller, and the mate right there that you think had a wonderful answer, he copied and pasted from Google

Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nucleus of helium-4 is composed of two protons and two neutrons.
