The Average Stride Length in Running
Knowing your average stride length is necessary if you want your pedometer to measure the distance you travel. You can use several methods to calculate your stride length. Some involve a calculation using your height while others require you to walk a preset distance and count steps before conducting a calculation.
Basic Formula
Use a formula to calculate your stride length based on your height. The first formula takes your height in inches and multiplies it by .413 if you are a woman and by .415 if you are a man. So a 6-foot-tall woman would have a stride length of 29.73 inches while a 6-foot-tall man would have a stride length of 29.88. This gives a rough estimate for the average person. The average man is 69.4 inches, or about 5-foot-9, and the average woman is 63.8 inches tall, or about 5-foot-5. Using this formula, that makes the average stride length for a man 28.8 inches and the average stride length for a woman 26.35 inches.
Sprinter Formula
Another formula is based on research done on 100 m sprinters. If you are a top sprinting athlete, you are likely to have a stride length of 1.35 times your height in meters. One meter equals 39.37 inches. So for a 6-foot tall person, that's 1.8 m times 1.35 for a stride length of 2.5 m. That translates to a stride length of 98.42 inches. A longer stride length is one factor involved in running speed. 10-Step Calculation
You can measure your average stride length without taking your height into account using a 10-step test. Mark the ground where your right heel rests. Walk 10 steps. Mark the spot where your heel lands on the 10th step. Measure the distance between the two marks in inches. Divide the result by 10. Then multiply the result by 12 to get your stride length. This method may be less accurate than others that measure a greater distance because you start and stop at a complete halt, which you will not do during a normal stride, note experts at University of California Los Angeles. Distance Calculation
To get more accurate results, measure a 20-foot distance. Once you are up to speed in a normal walk, count the number of steps you use to cover the 20 feet. Divide 20 by the number of steps. This gives you your step length in feet. Multiply by 12 to get your stride length in inches. You can use a different distance. The basic formula calls for dividing the number of feet you use by the number of steps you take to cover it, then multiplying by 12. Alternately, walk around a quarter-mile track using the inside lane. A quarter mile is 1,320 feet, so you divide that by the number of steps you take. Then multiply by 12 to get your stride length in inches. Considerations
Numerous factors aside from height come into play with stride length. Flexibility and muscle mass will affect your stride length. Because both of these tend to decline with age, your stride length and thus your running speed may lessen as you get older. Use
No matter how you calculate it, use your stride length to estimate how many steps are equivalent to a mile for you. Take your stride length in inches. Then divide the number of inches in a mile, which is 63,360, by your stride length. For our 6-foot man with a stride length of 29.88, that equals about 2,121 steps per mile.
