Why do so many walls have a bumpy texture, what purpose does it provide?

It’s called texture and it adds depth and structure to what would normally be a blank wall. Allows for shadows and light to display which some people enjoy looking at.

People have mentioned a more pleasant appearance, but it also has a significant influence on the sound “feel” of a room. It can really reduce echo and other unpleasant auditory effects.

It also makes the wall much easier to finish. A smooth wall needs to be smooth or you’ll see all the bumps and imperfections. A textured wall covers that all up.

Hello, I am from Florida, where most of our homes have what we call “orange peel” walls. It’s a bumpy texture, similar to an orange peel. Generally it’s done because 1) it is cheaper (constructors can stop at level 3 drywall as opposed to going to level 5, where there are more layers and more sanding, I.e. more labor and cost). 2) the texture does a better job of hiding imperfections… smooth walls would show a flaw or indent real quick. 3) it’s easier to maintain. So if you have to touch up paint, with texture you can just dab on the area affected. If it were smooth, you’d probably have to paint the whole wall so you don’t see any lines.
