"Vertical jump tester" covers five very different tools, from a $300 swing-vane to a $6,500 force plate. This guide explains how each one actually measures a jump, what it can and cannot tell you, and how to match the method to your budget, your metrics, and how you test. No hype, just the trade-offs.
Almost every tester uses one of three physics approaches. The first is flight time: if you know how long an athlete is airborne, you can calculate jump height from gravity. Contact mats sense the instant the feet leave and land through force on the surface, laser and optical systems break a light beam, and slow-motion apps count airborne frames. They all infer height from hang time, which is why they share one honest caveat (more below).
The second is jump-and-reach: a Vertec or a marked wall measures the difference between standing reach and the highest point you touch. It reports reach height directly with no timing at all, so it is simple and cheap but gives no contact time and no RSI.
The third is impulse-momentum from a force plate: the plate measures ground reaction force directly and integrates the force-time curve to derive take-off velocity and jump height. This is the lab gold standard because it measures force itself rather than inferring height from time, and it unlocks data no other method can (rate of force development, phase breakdowns, true bilateral force asymmetry).
The shared caveat: every flight-time device (mats, lasers, and apps) can underestimate jump height for truly elite jumpers above roughly 0.70 m, and reports outcomes rather than the underlying force curve. For that population a force-plate or optical reference is the safer call. For everyone else, a validated, repeatable signal is what actually drives good programming decisions.
Not brands, but methods. Each measures something different, costs something different, and fits a different program. Where a type is the better choice, we say so.
The classic swing-vane device (or a chalked wall). It measures jump height only as the gap between standing reach and the highest vane touched, with no contact time and no RSI. Cheap, simple, and reliable for a quick field check, but it is manual and not a reactive-strength tool.
Price tier: ~$300 to $600 (estimate).
Best for: quick, low-cost jump-height checks where contact time and RSI do not matter.
A slow-motion video app estimates height from airborne frames. It is the most accessible option and nearly free, but it depends on operator and frame-selection judgment, which adds variability, and it is slow when you are testing a whole roster. Useful for a casual baseline, not for trustworthy team tracking.
Price tier: free to ~$10 (estimate).
Best for: casual, occasional self-testing on a tight budget.
Contactless light barriers or LED grids infer height from flight time, so they need no landing surface and suit outdoor or approach jumps. The range is huge: entry devices like OVR Jump start around $299 and report RSI, while lab-grade optical systems such as Optojump reach into the thousands and add gait analysis. Optical timing is more context-sensitive than a force threshold.
Price tier: ~$299 (OVR) to ~€2,850+ (Optojump, estimate).
Best for: outdoor and approach jumps, or a well-funded lab needing optical precision.
Step on and go. A force-sensing mat reads jump height, ground contact time, and RSI directly from force on the surface, so it is fast for teams and purpose-built for reactive testing. Plyomat sits here: force-plate validated, no subscription, with on-device results plus the free app. This is the affordable, portable middle of the market.
Price tier: ~$200 to $1,400 (varies by system).
Best for: affordable, portable RSI and jump-height testing across a team. See the mat shortlist.
The lab gold standard. By measuring ground reaction force directly, a force plate produces the full force-time curve, true bilateral force asymmetry, and jump-strategy variables that no flight-time method can. The trade-off is cost and portability: it is expensive, often on a lease, and usually a fixed-space setup rather than grab-and-go.
Price tier: ~$6,500+ or lease (estimate).
Best for: labs needing full kinetics and the budget for it. See jump mat vs force plate.
| Tester type | How it works | Price tier | Measures RSI | Portable |
|---|---|---|---|---|
| Jump-and-reach / Vertec | Reach-height difference | ~$300–$600 | No | Yes |
| Phone app (slow-mo) | Flight time from video frames | Free–$10 | No | Yes |
| Laser / optical timing | Flight time from a light barrier | ~$299 to €2,850+ | Often | Yes |
| Contact / jump mat | Force on the mat surface | ~$200–$1,400 | Yes | Yes |
| Force plate | Ground reaction force (direct) | ~$6,500+ / lease | Yes | Lab setup |
Prices are approximate estimates that vary by region and reseller. "Measures RSI" requires a tester that times ground contact, which is why reach devices and most apps read No.
Start with what you need to measure, not price. If you only need jump height for a quick field check, a Vertec or even an app is enough and a mat is overkill. If you want ground contact time and RSI, which is where plyometric and reactive progress actually shows up, you need a tester that times ground contact: a contact mat, a laser barrier, or a force plate. Reach devices and most phone apps cannot give you that.
Next, weigh team throughput and portability. Testing a full roster rewards a step-on-and-go mat or a fast app over anything tethered to a laptop, and an on-device screen removes the phone bottleneck entirely. For outdoor or approach jumps, a contactless laser that needs no landing surface is genuinely better. A force plate is rarely the quick-throughput choice.
Then set your budget tier honestly, and decide between own-it-once hardware and a subscription, because a recurring fee changes the true multi-year cost. Finally, weigh accuracy and validation. Force plates and lab optical systems are the references; affordable testers trade a little precision for price and portability, and the better ones publish validation data rather than just claiming accuracy. Remember the flight-time caveat for elite jumpers above ~0.70 m.
We build Plyomat, so we will place it precisely: it is the affordable, portable, force-plate-validated contact mat in the middle of this lineup. The Controller 3.0 plus the free Plyomat 3.0 app report jump height, ground contact time, RSI, and DRI, with results on an on-device screen so you can test a team without a laptop, and there is no subscription. Validation against an AccuPower force plate came in at r≈0.97, ICC 0.85, about 1 cm mean difference in jump height.
It is not the answer for everyone, and we will not pretend otherwise. If you need only the cheapest possible jump-height check, a Vertec or an app is fine. If you need the absolute lowest price or outdoor approach jumps, a laser like OVR is hard to beat. If you need the full force-time curve and true bilateral force asymmetry, a force plate goes deeper than any mat.
