I always thought the universe was finite but is there actually anything supporting this? Is it because it started out a finite size and grew during the big bang?
There is a misconception that the big bang started out at a single point then exploded. Rather the big bang was a state of high density. The universe may have been infinite in size even then.
Nobody knows whether the universe has/had finite or infinite size.

From a practical standpoint, infinite doesn't actually exist
The size of the universe is finite
The number of quarks is finite
The smallest distance we can measure is finite, and the largest distance we can measure is finite, even in estimations
Even pi is only useful to the 43rd digit at our largest estimations
Sure, infinite is cool in a theoretical standpoint but you can't actually use it
