run a piece of string around all of the pulleys and tensioner so both ends meet, then just measure the length of the string and get a poly vee belt in that length mate.

When I supercharged mine and had to get a new belt, I ran some string round and measured it, then done the same thing again but slackened the tensioner fully.... Then got a belt in the middle of the two measurements, so the tensioner was bang in the middle of its range of movement.

There are literally thousands of belt sizes, there's always something that will fit.
