Know your vertical.
One video. VertChecker tracks your body, times your flight to the millisecond, and computes your vertical jump from pure projectile physics.
VertChecker is the fastest way to check your vertical: film one jump from the side — any phone, 60 fps or better — upload the clip, and read your jump height in inches or centimeters. A pose model tracks your body through every frame, contact detection finds takeoff and landing, and projectile physics turns flight time into height. Standing vertical or running approach, measured anywhere: no Vertec, no jump mat, no wall.
Vertical jump, explained — the test, the physics, the benchmarks
How do I test my vertical jump?
Film one jump from the side and upload the clip — VertChecker tracks your body frame by frame, times your flight, and converts it to jump height with projectile physics. No wall, no chalk, no Vertec: a phone at 60 fps is the whole setup.
How high can I jump?
Most untrained adults jump 12–20 inches (30–50 cm); trained athletes clear 24–30 or more. The only way to know your number is to measure it: record one jump, upload it, and read your height in seconds.
What is a good vertical jump?
Common benchmarks: 16–20 inches is average for men and 12–16 for women, 24 is athletic, 28 is excellent, and 32-plus is elite — NBA and NFL combine verticals typically land between 28 and 40 inches.
How does VertChecker measure a vertical jump from video?
A pose model finds your body in every frame, contact detection pins the takeoff and landing frames, and physics does the rest: a body in free flight rises exactly g·t²/8 for a flight time of t. Flight time is the same principle force plates and jump mats use — VertChecker reads it off your video.
How accurate is a video vertical jump test?
Frame rate sets the floor: at 60 fps a frame is about 17 ms, at 240 fps about 4 ms. Automatic takeoff and landing detection can drift on messy clips (allow ±4 in / ±10 cm), so every result opens in a frame seeker where you verify — or correct — the exact frames before trusting the number.
Do I need special equipment for a vert test?
No — any modern phone can check your vertical. Film side-on from 3–5 meters at 60 fps or higher (120 or 240 fps slow-mo capture is even tighter), keep your whole body in frame, and upload straight from the camera roll.
Does it work for a running approach jump?
Yes — standing verticals and approach jumps both measure, because flight time doesn't care how you got off the ground. Keep it to one jump per clip, 15 seconds max, filmed from before takeoff to after landing.
Is VertChecker free?
Your first 2 analyses are free when you sign in — no card. After that, credit packs start at $3.75 for 5 analyses and get cheaper in volume; you pay per measurement, never a subscription.
