On further investigation of pipe insulation options, I think I finally figured out what all the measurements mean.

There's the pipe diameter (which translates to the diameter of the center hole through the foam),

and length is obvious,

but the "WALL" measurement left me shrugging, since Home Depot didn't have a lot of choices in stock.

But it's wall thickness, so doubling that amount and adding the pipe diameter to that gets you the diameter of the OUTSIDE. The one I picked up from Home Depot was 6 feet of 1/2" with 1/2" wall.

As you can see from this picture, there's room for plenty more (like, 3/4" wall, if you can find it), but 1" wall would be too much.
