What Is a Good Vertical Ratio for Running?

What is vertical ratio in running?

Vertical ratio is your vertical oscillation (how much you bounce up and down with each step) divided by your stride length, expressed as a percentage. It answers a simple question: for every centimeter you travel forward, how much energy are you spending moving up and down instead?

A runner who bounces 9 cm per step and covers 120 cm of stride length has a vertical ratio of 7.5% (9 ÷ 120 × 100). A runner who bounces the same 9 cm but only covers 90 cm of stride length has a vertical ratio of 10%. Same bounce, different efficiency — because the second runner is "wasting" more of their vertical motion relative to how far they're actually moving.

How is vertical ratio different from vertical oscillation?

Vertical oscillation (VO) is the raw number — the centimeters your torso rises and falls with each stride, usually measured by a running watch's accelerometer or a chest-strap sensor. Across recreational runners, VO commonly falls somewhere in the 6-13 cm range, with faster and more efficient runners typically toward the lower end.

The problem with VO on its own is that it doesn't account for pace or stride length. Someone running a 10-minute mile and someone running a 6-minute mile could both post a 9 cm vertical oscillation, but the faster runner is covering far more ground per bounce — so their form is arguably more efficient even though the raw number looks identical. Vertical ratio corrects for this by normalizing bounce to distance traveled, which is why running-dynamics tools (Garmin, Stryd, and similar sensors) report both numbers side by side rather than just one.

What's a good vertical ratio range?

Most running-dynamics guidance treats a vertical ratio below roughly 7-8% as good, with values in the 8-10% range considered average for recreational runners, and anything consistently above 10% flagged as an area where the runner may be spending more energy bouncing than moving forward.

Vertical ratio General interpretation
Below 7% Efficient — low vertical cost per stride
7-10% Typical range for most recreational runners
Above 10% Higher vertical cost; may be worth a closer look

Treat these as general reference bands, not pass/fail thresholds. Vertical ratio varies with terrain, fatigue, and pace within a single run — it's normal to see it drift upward late in a long run or on hills, and that's not automatically a problem.

Why do elite runners tend to have lower vertical ratios?

Elite distance runners tend to show lower vertical ratios than recreational runners on average, which fits the general idea that less vertical motion per unit of forward travel corresponds to lower energy cost at a given pace. But this is a tendency observed across groups, not a rule that guarantees a faster time if you force your own ratio down.

Running economy is influenced by many interacting factors — cadence, stride length, braking forces at footstrike, muscle-tendon stiffness, and individual anatomy — and vertical ratio is one signal among several, not a standalone target. Chasing a lower number by consciously flattening your bounce can sometimes backfire if it shortens your stride awkwardly or changes your foot strike angle in ways that feel unnatural. Most coaches suggest treating vertical ratio as a trend to watch over weeks, not a number to force lower in a single session.

Can you estimate vertical ratio from a phone video?

Not reliably — and it's worth being upfront about why. Vertical ratio requires two inputs: precise vertical oscillation (millimeter-level torso displacement per step) and stride length, both measured many times per second. That level of precision typically comes from an accelerometer-based footpod, chest strap, or running watch designed for it, or from a multi-camera motion-capture setup in a gait lab.

A single phone video, even filmed from the side, can give you a rough visual impression of how much a runner bounces, but it can't produce a trustworthy percentage. Camera angle, frame rate, and distance from the subject all distort the estimate. What a phone video can measure with reasonable confidence is cadence — your steps per minute — because that's a simple count of foot-strike events over time, not a fine-grained distance measurement.

This is the honest limitation behind most phone-based form-check tools, including StrideIQ: it's useful for a quick cadence and general form check from a single video, but it isn't a substitute for a sensor built to measure oscillation directly, or an in-person gait lab if you need lab-grade vertical ratio numbers. If cadence and overall breathing efficiency are more your concern than a precise oscillation number, that's also where pacing and breathing patterns tend to matter more day-to-day than shaving a percentage point off your bounce.

What can vertical ratio NOT tell you?

Vertical ratio is a useful efficiency signal, but it has real limits worth naming plainly.

First, the evidence linking a specific vertical ratio to injury risk is limited and mixed. Running biomechanics research has not established a single "correct" vertical ratio that prevents injury, and no phone app or wearable can diagnose a current or future injury from this metric. If you're dealing with pain — knee, shin, IT band, or otherwise — a lower vertical ratio is not a treatment, and you should see a physical therapist or sports medicine physician for an individualized evaluation rather than trying to fix pain through a metric alone.

Second, consumer-grade estimates (whether from a watch, footpod, or phone video) carry real measurement error. Studies comparing wearable running-dynamics sensors to lab-grade 3D motion capture generally find reasonable agreement for group trends but larger error for any single stride. Treat your number as an estimate with a margin of error, not a lab result.

Third, a "good" number on paper doesn't guarantee better running for you personally. Two runners with identical vertical ratios can have very different injury histories, strength levels, and running economy, because vertical ratio captures one slice of movement and ignores hip strength, ankle mobility, prior injuries, and dozens of other factors a gait lab or physio assessment would look at together.

If you want a rigorous read on your vertical oscillation and ratio, a running-specific gait analysis lab with force plates and high-speed cameras, or a sports physical therapist with 2D/3D video tools, will give you far more reliable numbers than any phone-based estimate — and can put those numbers in context with your strength, mobility, and injury history, which a single metric never can.

Frequently Asked Questions

What is a good vertical ratio for running?

A vertical ratio below roughly 7-8% is generally considered good, 8-10% is typical for recreational runners, and consistently above 10% suggests relatively higher vertical energy cost per stride. These are general reference bands, not strict cutoffs, since ratio naturally shifts with pace, terrain, and fatigue.

Is vertical ratio the same as vertical oscillation?

No. Vertical oscillation is the raw distance your body bounces up and down per step, usually in centimeters. Vertical ratio divides that number by your stride length, so it accounts for how far you're traveling per bounce rather than looking at bounce alone.

Can a phone video measure my vertical ratio accurately?

Not reliably. Vertical ratio needs precise, high-frequency measurement of both vertical displacement and stride length, which typically requires an accelerometer-based sensor, running watch, or motion-capture lab. A phone video can give a rough visual impression but not a trustworthy percentage.

Does a lower vertical ratio mean I'll run faster or get injured less?

Lower vertical ratios are associated with running economy in general population comparisons, but the relationship isn't guaranteed for any individual, and evidence linking vertical ratio directly to injury risk is limited. It's one signal among many, not a standalone predictor.

What's a normal vertical oscillation range for runners?

Vertical oscillation commonly falls between about 6 and 13 centimeters across recreational runners, with faster, more efficient runners often toward the lower end of that range. It varies by pace, so it's usually more informative alongside vertical ratio than on its own.
