Why not put a small loop in one end and thread the other end through it.
Then if you mark the rope you just pull through to you get the distance

That's brilliant!!! Brilliant, I tell you. ;-)

This has the added advantage of providing for intermediate sizes.

The extra rope can be laid alongside the circle. If the extra rope
creates too much clutter, I can make 2-3 sizes.

Thank you very much.

Glad that helped. Sometimes throwing out a question to the groups will give

through a bunch of ideas, but one may be just the thing.

Quite right. This time, it seems to have struck pay dirt.
