rack cable length

This is probably a stupid question, but....

We've got a few racks in a colo. The racks don't have any decent cable
management (square metal holes to attach velcro to). We either order
cable too long and end up with lots of loops which get in the way (no
place to loop lots of excess really) or too short to run along the
side (which is worse). It appears others using the same racks have
figured this out, but...

Do y'all just order 10 of each size per rack in every color you need
or is there a better way to figure this out? I'm guessing something
like 24 inches + 1.75 inchex x Us) + 24 inches and round up to
standard length...?
