By the first principle energy level I assume you are referring to the lowest atomic orbital or ta principal quantum number of 1. This orbital holds 1 pair of 2 electrons.

Are sublevels smaller or larger than energy levels?

Depends on what one means by "smaller". Since sublevels are "inside" or part of the principle energy level, then yes, they are smaller.
