In practice I find that anything smaller than .0001 inches can't really be felt, and the difference between .0001 and .0002 is indiscernible.

13 nanometers is closer to .0000005 inches.

But you can feel that the texture is somehow different.

It's not that you can feel individual features, but rather that a repeating pattern of that size can be distinguished from a smoother surface.
