Baseball & Softball Bat Size Calculator
Determine exact bat length (inches), drop weight (-3, -5, -8, -10), total ounce mass, and barrel diameter based on height, weight, and league regulations (BBCOR, USSSA, USA).
- 2026 High School & College BBCOR
- Plate coverage radar telemetry
Tennis Racket Grip Size & String Tension Calculator
USRSA-calibrated palm crease fitting engine. Recommends exact handle size (L0 to L5), overgrip thickness offset, and arm-safe string tension by string material (poly, gut, multi).
- Tennis elbow shock dampening
- US & European grip standards
Golf Club Distance & Shaft Flex Calculator
Calculate your complete 14-club carry and total yardage bag gapping, optimal shaft flex (L, A, R, S, X, TX), and shaft weight profile based on driver swing speed and tempo.
