Original Curmudgeon
This point was confusing to me at first, too. I was looking at his itty bitty head and thinking "no way!" He was being fed two fuzzies when I got him, but after folks saw his pics, they said he was ready for adult mice. I bumped him up to hoppers for a few feedings, and now he's ready to take his first adult tomorrow. Based on the 1.5 x girth size, he's been ready for a while. I just didn't want to bump him up two sizes.Lots of good advice here! I'll reiterate my favorite points.
1.5X the girth at the widest part of the snakes body. Don't let the size of the head worry you. He can do it.
Good luck. Let us know how it goes with a bump.
