Step length is about 41% of body height at a normal pace (5 km/h). Calories use a MET value of 3.5 for walking: kcal = 3.5 × weight × hours. Taller people and faster walkers cover more distance with the same number of steps.
Any increase helps. Large studies link about 7,000–10,000 steps a day with lower health risks for most adults; older adults benefit from fewer.
