Quickdraw Calculator
Calculate quickdraw requirements based on route length and bolt spacing for sport climbing.
Total height of the route
Average distance between bolts
How We Calculate This
This calculator estimates the number of quickdraws needed based on route height and bolt spacing.
Formula
Bolts on route = Route height / Bolt spacing (rounded up)
Quickdraws needed = Bolts + Anchor draws + Spares
Sport climbing routes typically have 2 anchor bolts at the top requiring their own quickdraws or a dedicated anchor setup.
