Or use a tailors tape measure. That would be a whole lot more accurate. BUT remember when you are measuring, you have to allow for the adjustment that is already there. The best thing you could do would be to measure it with the P/S at about 1/2 to 3/4 in. That way you have room to adjust as the belt wears.

Kinda scary, I'm being nice. I must be in a good mood.
Hey guy. I looked for a couple of minutes and seen tons of slipping belt questions but nothing about the length. Most of the threads i've read on here are pretty friendly, but I guess there's an Arse Hole like you in every group. I didn't mean to cluter the data base, I just got tired of looking. Looks like I've got a lot to learn about your site here. I'll try to learn quick so you don't have a coronary. Thanks for the links.
I'm an equal opportunity asshole. On the plus side, at least you poked around a bit before asking. That, and your English is, at least, tolerable. Enjoy your stay here.
