A: In theory, yes. It might be a bit tight to get on. We have it on a 30" square and it goes on easily but keeps its square shape.
A: As the description states, the cover will fit up to a 30" square fire pit. Your best bet to ensure a fitting cover would be model #: UFPS4040
A: I would say yes .Is has Velcro belts on doth sides to pull a little tighter if need be. Fits perfect on the 32". So very little difference for a 31 1/2".
A: Yes if it covers 32 it will cover 31 1/2 too.
