Stride Length Calculator

At 5 ft 7 in, a normal walking stride is about 27 inches; a running stride depends on pace

Stride length, in the sense used by watches and pedometers, is the distance of one step: from where one foot lands to where the other foot lands. Gait researchers use “stride” for something different, the two steps between one foot landing and the same foot landing again, so this page says “one step” whenever the difference matters. Omron Healthcare says it is common to estimate walking stride as height × 0.37 to 0.45. For someone 5 ft 7 in (67 in) that is 25 to 30 in, and this calculator uses the middle of the range, height × 0.41, or about 27 in, as the estimate for a normal pace. At that length a mile takes about 2,347 steps, and 10,000 steps cover about 4.26 miles.

Running stride depends more on how fast you run than on height. In a population-average equation built from 256 runners, a 10:00-per-mile pace gives a stride of about 38 in and an 8:00 pace about 47 in. The calculator above estimates walking stride from height (sex and age only set the walking tempo), and running stride from pace. If you have measured a distance and counted your steps, it works out your actual stride and compares it with the estimate. The figure drawn on screen is scaled to the height you enter and walks or runs at the stride and steps-per-minute it has calculated.

When you need to know your stride

• Your watch or pedometer distance looks wrong: most step counters multiply steps by a stored stride length. If the stored value is just 2 in longer than your real stride, 10,000 steps come out about 0.3 miles too long.
• You are entering walking and running stride into a device: Fitbit takes a walking stride and a running stride separately. Entering the walking value as your running stride makes your runs measure far too short.
• You are turning a step goal or a distance into steps: “How far is 10,000 steps?” and “How many steps is 5 miles?” both depend on your stride.
• You are working on running form: at the same pace, a higher cadence means a shorter stride. Knowing your current stride shows how much a target cadence would change it.
• You are watching for a shortening stride with age: a study that followed 666 adults aged 70 and older in Japan reported more cognitive decline among those with a shorter stride (see “Stride length and aging” below).

If your goal is weekly activity rather than distance, the Physical Activity Guidelines for Americans (2nd edition, 2018) recommend that adults get 150 to 300 minutes of moderate-intensity aerobic activity a week, or 75 to 150 minutes of vigorous activity, and they count brisk walking as moderate. In steps, a cadence of 100 or more a minute corresponds to moderate intensity (about 3 METs) in a study of 76 adults aged 21 to 40 (Tudor-Locke et al. 2019).

How to use the calculator

1. Enter your details: put your height, sex and age at the top. Height drives the walking stride estimate. Sex and age set the walking speed typical for that age group, which feeds steps per minute and the time to walk a mile.
2. Read the walking stride: in the walking card, choose a walking pace (slow, normal or fast). The big number is the one-step estimate, and the bar underneath shows where it sits inside the height × 0.37 to 0.45 range.
3. Read the running stride: in the running card, enter your pace in minutes and seconds. If your watch shows cadence (steps per minute), enter it as well and the calculator uses that value instead of an estimate.
4. Check against a measurement: in either card, choose “From a measured distance” and enter the distance and the number of steps you took over it. You get your real stride, and the walking card also tells you how far it is from the height-based estimate.
5. Figure and device settings: select a card header to switch the figure between walking and running. If the motion bothers you, press “Pause”. The device rows below the calculator show where to enter your value on Fitbit, Garmin and Apple Watch.

How the numbers are calculated

The factor 0.41 is the middle of Omron's range (0.37 to 0.45). The pace ratios come from a Swedish reference study of 233 healthy people aged 10 to 79 (Öberg et al. 1993), comparing the slow, normal and fast mean stride of 12 male and female groups aged 20 to 79. A slow walk had a stride 0.86 times the normal one and a fast walk 1.14 times, with speeds of 0.67 and 1.32 times. Typical speeds by age and sex come from a meta-analysis of 41 studies and 23,111 people (Bohannon & Andrews 2011). The running cadence equation is a population average from 256 runners who shared Garmin recordings (van Oeveren et al. 2019), and the calculator uses it only between 1.64 and 4.68 m/s, which is 16:21 to 5:44 per mile.

Walking stride by height

Figures are height × 0.41 × the pace ratio. Sex and age are not used for the stride estimate. Omron's range is also based on height alone, and pace matters so much that the same person's stride changes by 6 to 7 in (15 to 19 cm) between a slow and a fast walk (Öberg data below).

Treat the table as a starting point. At the same height, leg length, shoes and walking habits move the number by an inch or more, so measure once and enter that value into your device.

How pace and place change your stride

Stride changes a lot even within one person. In Öberg et al. (1993), a man in his twenties took a step of 52.7 cm (20.7 in) at a slow pace, 61.6 cm (24.3 in) at a normal pace and 71.2 cm (28.0 in) at a fast pace. For a woman in her twenties the figures were 51.8 cm (20.4 in), 59.1 cm (23.3 in) and 66.7 cm (26.3 in). Pace alone moved the step by 15 to 19 cm, or 6 to 7 in.

Where you measure matters too. That study measured a 5.5 m stretch of an indoor walkway. The authors noted that stride was shorter and steps per minute higher at every pace than in another study measured on a 60.5 m outdoor path (Waters et al.), and that indoor and outdoor reference values should be kept separate. In Huber et al. (2022), 51 healthy adults (median age 60) walked 1 km outdoors with a GPS watch. The median stride was 68.9 cm (27.1 in), the median was 1,451 steps per kilometer (about 2,335 per mile), the mean cadence was 112 steps a minute and the mean speed was 1.28 m/s (2.9 mph). Measuring on a short indoor hallway can give a shorter stride than you take outside.

Typical stride and walking speed by age and sex

The table pairs the average one-step length at a normal pace that Öberg et al. (1993) measured in groups of 14 to 15 people with the usual walking speed from the Bohannon & Andrews (2011) meta-analysis. The strides come from a short indoor stretch and run shorter than outdoor strides. The calculator does not use them directly; it uses only the speeds, to work out steps per minute.

In Bohannon & Andrews (2011), men in their forties walked fastest, at 1.434 m/s (about 3.2 mph), and women aged 80 to 99 slowest, at 0.94 m/s (2.1 mph). After 80, speed drops enough that a mile takes about 28 minutes even at the same stride length. The calculator uses the twenties values for ages 18 to 29 and the 80 to 99 values for ages 80 and over.

Running stride by pace

As runners speed up, stride grows much more than cadence. In Cavanagh & Kram (1989), male recreational runners on a treadmill went from 3.15 to 4.12 m/s (7.0 to 9.2 mph); cadence rose only 4% while stride grew 28%. At a given speed the correlation between height or leg length and stride was 0.36 or lower, and the authors concluded that body dimensions cannot predict an individual's stride well. That is why this calculator estimates running stride from pace, not from height.

The 256 runners behind this equation averaged 44 years old and 5 ft 11 in (181.4 cm), and 85.5% were men. The same study found that leg length, body weight, age and running frequency were related to cadence at a given speed, so if your build or experience differs from that group, your cadence and stride can differ noticeably from the table. If your watch shows cadence, enter it as well. To see how a change in cadence changes your stride, try the running cadence calculator.

How to measure your stride

1. Ten steps: walk 10 steps the way you normally do, measure from the toe where you started to the toe of your last step, and divide by 10 (Omron and Tanita instructions). If 10 steps cover 6.5 m (21 ft 4 in), one step is 65 cm, or 25.6 in.
2. A known distance: measure about 50 ft with a tape, take a few steps beforehand to get up to speed, and count your steps across the stretch. Fitbit's help page says to walk at least 20 steps. 50 ft in 22 steps is 27.3 in.
3. One lap of a 400 m track: lane 1 of a standard outdoor track is 400 m, a little less than a quarter mile, around. Walking it in 570 steps gives 27.6 in (70.2 cm); running it in 392 steps gives 40.2 in (102.0 cm).

Whichever method you use, measure at your usual pace, and measure walking and running separately. Enter the distance and step count under “From a measured distance” and the calculator returns your stride and steps per mile. To turn a day's steps into distance, use the steps to distance calculator.

Entering your stride in a watch or pedometer

• Fitbit (Google Health app): stride length is set from your height and sex, and the stride length setting lets you edit walking and running separately. When you record a run with GPS, the running stride updates automatically, and Fitbit says running at a comfortable pace for 10 minutes or more makes it more accurate.
• Garmin: the vívofit 4 manual explains that in the Custom Stride Length setting you enter a known distance and the number of steps you took over it, and Garmin Connect calculates the stride.
• Apple Watch: there is no field for stride length. Record about 20 minutes of outdoor walking or outdoor running in the Workout app at your usual pace, in an open area with good GPS, and the watch calibrates. If you move at several paces, Apple advises recording 20 minutes at each one.
• Pedometers (Omron, Tanita and others): distance is the stride you set times the number of steps. Both companies define stride as the length from the toe of one foot to the toe of the next, which is the same as measuring heel to heel.

Stride length and aging

Steps get shorter with age, and the change is studied as a health signal. Taniguchi et al. (2012) followed 666 community-dwelling Japanese adults aged 70 and older (median follow-up 2.7 years). Those in the shortest third for stride were 4.42 times (men, stride at maximum speed) and 5.76 times (women, stride at usual speed) more likely to show cognitive decline than those in the longest third. The authors concluded that stride may predict cognitive decline better than walking speed does. It is an observational study, so it does not show that lengthening your stride lowers the risk. If your steps have clearly shortened or you fall often, it is reasonable to see a doctor.

Common mistakes

• Entering a two-step length: in gait analysis, “stride” means the distance until the same foot lands again, which is two steps. Entering that into a device's stride length field doubles your distance. The stride lengths in Fitbit, Garmin, Omron and Tanita instructions are all one step.
• Using the walking value for running: at 10:00 a mile, a running step is about 11 in longer than a walking step for a person 5 ft 7 in. Using the same value makes your running distance come out nearly 30% short.
• Using height × 0.45 as is: 0.45 is the top of the usual range. If you walk at a normal pace, distances can come out too long.
• Measuring in a short indoor hallway: starting and stopping makes steps shorter. Take a few steps first and count as you pass through the stretch.
• Measuring on a slope: stride changes uphill and downhill. Measure on level ground and read trail distances together with a GPS track.

Limits

• The walking estimate is a ratio of height alone, so it cannot capture differences in leg length, shoes or walking habits. A few inches' difference at the same height is common.
• The pace ratios and the speeds by age and sex are averages from studies of adults, mostly Western, and are not data specific to the United States. Steps per minute and walking time assume you walk at that average speed, so for very short or very tall people they can differ more from real life.
• The running cadence equation is a population average from 256 runners, mostly tall men, and cadence at the same speed varies a lot from person to person. Outside 16:21 to 5:44 per mile the calculator does not estimate.
• The calculator does not work out results for anyone under 18, because body proportions differ.
• It is not a tool for judging health. If your stride has shortened or your gait has changed, talk to a health professional.
