looks like it would easy enough to take a regular tape measure, and write on the back of it, various sizes, and divide by Pi; or just even a cloth style measure, which weighs nothing, and approximate in your head, or use calculator/phone or even a little wallet chart.
i suppose for a plumber, who is doing this day in and day out it might be useful.
actually, if the size is the pure limiting factor, you could make a string the right length, and trees that are bigger won't fit, and would be heritage, and lesser trees would meet or overlap and wouldn't be (and thus are edible?)
