Dunk Vert Calculator – Accurately Measure Your Vertical Leap for Dunking Success
Dunking a basketball isn't just about raw strength or height. It's about vertical efficiency, body mechanics, timing, and how well you convert leg power into height at the exact right moment.
What "Vert" Really Means
Your "vert" is simply your vertical leap — the distance between your standing reach and the highest point you touch when you jump. A dunk vert calculator compares that number against what's required for your rim height.
Two Types of Vertical Jump
- Standing vertical: No steps, straight up from a static position.
- Approach (running) vertical: A few steps into the jump, usually 3–8 inches higher due to momentum.
Most dunk attempts use an approach jump, so if you're only testing standing vertical, you may be underestimating how close you actually are.
What Limits Your Vert
- Force production — how much power your legs generate through the ground.
- Rate of force development — how quickly you can apply that force.
- Technique — arm swing, plant angle, and body positioning at takeoff.
- Mobility — tight hips or ankles quietly cap your ceiling.
Where to Start
Enter your height and standing reach into the Dunk Calculator to see your target, then build a plyometric and strength routine around closing that specific gap.
