size 11 or 12

i’m about ready to buy the oura ring 4 ceramic (white) and can’t decide between size 11 and 12. 11 is snug-not overly tight-but i’m worried in the summer months it will be too tight. and the 12 feels too loose, but notice it does allow a bit of wiggle room when fingers swell during my workouts. i’ve worn both for 24+ hours, but it’s not summer yet and don’t know how much my fingers will actually swell. should i wait until summer to buy? i was thinking to buy the 11 first, and if it doesn’t feel great swap it out within 30 days. any ideas or suggestions in picking out the proper ring size? thanks in advance!
