Belt Length??

On a 92 LX 2.3 what would be the belt length for just skipping over the ac. The car is out of town at the moment so I dont have it handy to use a string and measure. Im doing this just until I can get it fixed because the compressor pulley is making a rattling noise even with the ac off. Felt like the little plate on the front of the compressor pulley is loose or something

thanks
