How to Use This Calculator

Enter your height, reach (wingspan), inseam, and shoulder width in centimeters.
Select your fighting stance and enter your opponent's reach and inseam for comparison.
Review your reach advantage, kick reach advantage, reach index, and ape index.
Check jab, cross, hook, uppercut, front kick, roundhouse, and teep ranges for your effective striking distances.
Use the optimal fighting distance to inform game plan decisions about inside vs. outside fighting.

How the result changes with Reach/wingspan (cm)

Jab range (cm): Effective distance for landing a jab.
Cross range (cm): Effective distance for a rear-hand cross.
Hook range (cm): Effective distance for a lead/rear hook.
Uppercut range (cm): Effective distance for an uppercut.
Front kick range (cm): Effective distance for a front kick.
Roundhouse range (cm): Effective distance for a roundhouse kick.
Teep range (cm): Effective distance for a push/teep kick.
Reach advantage (cm): Your reach advantage over opponent (positive = longer).
Kick reach advantage (cm): Your kicking range advantage over opponent.
Reach index: Reach-to-height ratio (average ~1.0, exceptional > 1.04).
Ape index (cm): Reach minus height — positive means arms longer than height.
Optimal fighting distance (cm): Distance where you can land but opponent struggles to reach.

Identify Input Parameters
4 parameters
Height (cm) = 180, Reach/wingspan (cm) = 183, Inseam/leg length (cm) = 82, Shoulder width (cm) = 46 = 7 input(s) provided
Calculate Jab range
Jab range = armLength + shoulderWidthCm * 0.4 + 8
94.9 = 94.9
Calculate Cross range
Cross range = armLength + shoulderWidthCm * 0.55 + 12
105.8 = 105.8
Calculate Hook range
Hook range = jabRange * 0.7
66.4 = 66.4
Calculate Uppercut range
Uppercut range = jabRange * 0.5
47.5 = 47.5
