This may be a silly question(s) but I'm going to ask.

Hey everybody, I hope you are all well. When we talk about appropriately sized prey items for feeding I usually hear to only feed your snake an item that is no larger than 1 to 1 1/2 times the snakes diameter/girth. My question is are we talking about the length or width of the prey item? I'm assuming it has to be the width. Caesar is about 6months old. He's 16" long and about 1/2" in diameter, the fuzzies are about the same width, maybe a hair wider, but they're at least an inch long. Is this the right size for him? They leave a slight bulge when he's done but not too big. (Pinkies don't leave any bulge in him at all.) It takes him a while but he always eats 1-2 fuzzies every 5-7 days. Which leads me to another question. How long should it take him to finish his meals? He can sometimes take 15-25 minutes to eat one item. If he has seconds, the 2nd one usually goes a bit quicker. I've also got about (12) fuzzies left which should last me about 30-45 days. I've got (25) hoppers in the freezer after the fuzzies are gone. The hoppers are of course a little larger than the fuzzies. Should he be ok to move up once the fuzzies are gone? I'd hate to have to buy more fuzzies. I don't want the hoppers to go bad either since they've already been in the freezer for about 2 months. I know this is a long post and I've thrown a lot out there but thanks for reading and I appreciate any feedback.
