The amount of steps necessary to walk a mile depends on step length. The average step length for men is 2.59 feet, and the average step length for women is 2.16 feet. Dividing the length of a mile by the feet per step equals 2,038 to 2,444 steps per mile.
The average human cadence (rate of taking steps) is 117 steps per minute, which results in a mile talking about 17 to 20 minutes to walk. Pedometers, which simply measure the number of steps one takes, are useful for tracking activity; health professionals recommend walking at least 7,500 steps, or about an hour, every day to reap the health benefits.
