The bigger the better. Never kept them in a small 1 gallon. I have a total
of 14 bettas. Have experimented with different sizes. Really like the
2 gallon. It's easy to clean and fun to decorate. Just know where you
will put the tank, not by a window. Don't overcrowd the tank with
decorations either. Cleaning all those tanks is a lot of work, but I love them.

They are fine in a low depth of water, enough to spread out their fins, but would prefer a large planted area to float about through plants.
The water capacity mainly effects how quickly the betta will alter the water chemistry by being present in it- from the protective slime on their body, waste from you feeding it, and any left over food if you over-feed it should it not east what you give it.
The less water, the more often you need to do water changes to ensure that the betta is not going to be chocking on its own waste. This is a VERY basic fish understanding not many realize at first adventuring into fish keeping.
Same goes for the cups that they come in; There is only so much water in them, so theoretically if you make the water changes as required, they can survive in the cups, but they will not -thrive- in them.
I have betta in this 2G Hex Tank. This tank works best if you baffle the filter. Otherwise this is a fine tank if you put 1-2 plants in it to make it interesting, or a decoration the betta can use to avoid the water current that will not tear its fins.

Bettas are air breathers, so they don't need a big deep tank to be able to survive. They do need some space to move around in, but are not active fish, so small tanks work fine. Anything that is at least three times the length of the fish is fine in my experience. They sell bowls in .5 gallons up to 5 gallons. a 1 gallon tank is perfect I think. It gives you room to add decorations and to see the fins spread out nicely. Hope that helps. :-)
