How It's Calculated
Maximum reach = Standing reach + Vertical jump. The required reach depends on the rim height plus the overhead clearance needed for your dunk type.
- Average standing reach ≈ height × 1.33
- Rim touch requires max reach ≥ rim height
- Dunking requires max reach ≥ rim + 6–12"
- Hand size ≥ 8" helps grip a size 7 ball
