Use this guide to size your Hayabusa boxing gloves correctly. Fit is determined by hand circumference; glove weight (oz) is chosen for your body weight and intended training use. The same chart applies to the T3, T3D, S4, E1 and Marvel/Star Wars Hayabusa boxing-glove ranges sold at Made4Fighters — these all share Hayabusa's standard adult fit.
How to measure your hand
Take a flexible tape measure and wrap it around your dominant hand at the knuckles (the widest part), with the tape level and your hand relaxed and open.
Do not include the thumb in the measurement.
If you are between two sizes, try both — most fighters prefer the snugger size for a more responsive feel under wraps.

Glove weight by training use
Bag work and pad work: 10 – 14 oz for responsive feedback on the bag and a faster glove. The Hayabusa T3D and S4 ranges are common bag picks.
Sparring: 14 – 16 oz for most adults; 16 – 18 oz for heavier fighters. Sparring gloves should absorb shock for your partner, not just protect you. The T3 and E1 Sparring lines are designed for this.
Competition: follow the rules of your governing body — typically 8 – 10 oz for professional bouts and 10 – 12 oz for amateur. Always check before fight night.
Notes
If you are buying your first pair, prioritise the right weight for sparring before chasing a lighter bag glove — the heavier pair earns its keep first.
Bodyweight is a starting point, not the rule. If you punch hard or are training for sparring you can move up one oz; lighter recreational users can move down.
