As the title says.
I have Lydia following me at the moment and I have a habit of picking up everything and giving a lot of stuff to her to carry.

yes, there is a limit but it seems to vary. some (like lydia) can carry alot. others, not so much.

Yes, followers have a maximum carry weight, I'm not sure how it's calculated though..

It seems to be pretty high

At the moment she is carrying a whole load of Dragon Bones and Dragon Scales, following my recent slaying. And lets be honest, they're not light.


Is there an indicator when they get overburdened as with the pc?

seems the only indicator is when you are trading with them and want to give them something, if it's too heavy for them to carry it will be greyed out in your inventory so you cannot select it to give to them.

Ok, got ya, thanks very much.

Someone mentioned on another thread that you can still make them pick items up from the floor beyond this overencumbered point though, never tested it yet myself.
