# Calculate the Measurements of a Staircase

Calculator for the measurements, number of steps, step size, slope ratio and angle of slope of a straight staircase (or ladder). The angle is in degrees, the slope ratio is a number, all the other values are in cm. Here you can convert length units. Please enter one of these combinations* of values:

a) | - height of the staircase or of one step - depth of the staircase or of one step - the number of steps |
b) | - length, height or depth of the staircase - number, height or depth of one step - slope ratio |
