I aim for 19" long splits. That gives me wiggle room for inexact cuts and makes it a bit easier to fully load the stove. While 22" works, I wouldn't want most of my splits to be that long unless I was around more and didn't need to fully load the stove very often. This brutally cold winter, I've fully packing the stove very often and appreciate the wiggle room. Since I usually eyeball my cutting lengths, I'd say 95% of my splits are 18 to 20" long.
