I have a 200 amp main service with a sub panel of 60 amps connected to it for my basement.
Am I limited to how large a panel you can connect to a main panel? I have run out of space on the sub panel and really need to change it out for a larger panel with room for more circuits.
Any help is greatly appreciated.

Generally, not specific limit on the physical size of a subpanel. You can add a larger one, if you need space for more breakers.

But note that the wires to it, and the breaker controlling this subpanel will still be limited to 60A.

It's possible to have a situation where you have a dozen circuits in the subpanel, all in use and only drawing a small current (5-6 Amps each) -- but the total is over 60A, so the big breaker controlling this whole subpanel trips. (Like it should, for safety.) That can be annoying, and hard to fix -- you either have to replace the 60A breaker in the main box & the wires running to the subpanel with bigger ones, or not use so many of the circuits from the subpanel at the same time.

If you can deal with that possible problem, there should be no problem with replacing this subpanel with one that has more breaker spots.
