What curl range would you put curls like that into?

My hair is 2cish, but on curly days it always forms a bunch of curly tubes like that (like in my profile pic), each with the diameter of a roll of quarters or so. It looks similar to a 3b coil, but it's composed of more hair and has way less shrinkage, if that makes sense. I've noticed similar curls on the heads of many ladies on the 2 boards. They are definitely curls as opposed to waves, but seem to be categorically different from bouncy, spring-shaped curls. Are they cherub curls perhaps?
waves, loose coils, and cherub curls (=mixed 2s through 3a), very fine texture overall (but with medium and even coarse strands scattered throughout)
