Instructions
Enter information and select units of measurements in left
column. Click "Calculate".
Values above 47.24" (120 centimeters) are interpreted
as body height. In which cases, average step length is approximated
automatically by multiplying body height by 0.414. Entering an
actual step length may increase accuracy.
Step length can be measured by counting steps on course of
known distance (measured path, athletic field, etc.) then calculated
by dividing number of inches or centimeters on coarse by the
number of steps. For example 70 steps on a 50 meter course (5000
cm / 70 steps) would reveal a 71.43 cm step.
Step length is the distance between the point of initial contact
of one foot and the point of initial contact of the opposite
foot. In contrast, stride length is the distance between successive
points of initial contact of the same foot.
Step Standards
For ideal BMI, the minimum recommended daily steps for 612
year old children are 12,000 steps/day for girls and 15,000 steps/day
for boys (Tudor Locke et al 2004).
