Grip height in pole vault scales with your sprint velocity at the box. The faster the run, the higher you can grip without stalling on the pole. This calculator estimates a starting grip range and the corresponding pole length, calibrated against elite biomechanical data: 2000 Olympic finalists averaged 5.00 m grip on 9.8-10.0 m/s last-5m approach speed, and Bubka's documented final-strides reached 9.9 m/s at takeoff.
Grip height tracks the velocity of your sprint at the box, not your raw 100m time. The calculator estimates takeoff velocity as a function of your 100m PR (corrected to FAT), peak-to-average ratio (~1.10), and a level-dependent retention factor (beginners lose ~5% to pole drag; elite vaulters retain 100-105% of flat 100m peak speed).
Schade et al. (2022) and the broader biomechanical literature show peak height gain of approximately 0.54 m for every 1 m/s of additional run-up velocity. This is the ceiling: speed gains compound through grip height and push height, so improving sprint speed at the box is the highest-leverage variable in long-term progression.
Two athletes with identical 100m PRs can have very different optimal grips. Technique determines energy transfer from the run into the pole. The 1.00-1.80 ft/(m/s) multiplier in the calculator reflects this gap: beginners convert ~55% of what elite vaulters convert at the same speed. AI form check on video can measure your actual conversion ratio.
The calculator gives you a starting number. AI form check verifies whether your form is actually matching that number on the runway. Upload a clip from practice, and the AI tells you whether your takeoff velocity, grip height, and approach are landing where the calculator said they should.
