Steps of Stairs: Calculate Amount and Height
A simple calculator for the height of stairs, the step height and the number of steps. When e.g. climbing a tower and counting the steps, from this number and from the step height, the height of the tower can be estimated.
Please enter two values, the third will be calculated. The step height is in centimeters, the stairs height is in meters.
Examples:
• A staircase with n = 120 steps, each h = 16 centimeters high, has a height of H = 19.2 meters.
• The stairs between two floors of an average house with a floor height of 2.50 meters and a step height of 16 centimeters have theoretically 15.63 steps. So one of the steps would have to be a different height. This should be avoided. So here, for example, 15 steps are choosen with a height of 16.67 centimeters each.
• The world's longest stairway is a service stairway of a Swiss funicular railway. It has 11674 steps and a height of 1669 meters. So each step there has a height of 14.3 centimeters.
Stair steps should have a step height of 16 to 18 centimeters. At this height, they are more comfortable to climb and pose a lower risk of accidents than higher steps. The recommended depth, i.e. the area on which the foot can stand, should be 26 to 30 centimeters, which is roughly the same length as an average foot with shoes on. However, the foot usually does not reach the very front of the step. When going up, the heel hangs over on steps of this depth. During this upward movement, however, the body is tilted forward, so that the center of gravity is not on the heel, but further forward on the foot. When you go down the stairs, which has a greater potential for accidents than going up, the heel is positioned on the step, while the toes often protrude over the edge of the step.
