The Austrian Standard says that in flats the riser height (h) should have a maximum of 20cm and the tread depth (a) should have minimum of 24cm measured on the walking line. Staircases with more than 3 steps need a handrail. The clearance height needs to be 2.1m minimum. A landing has to be provided after 20 steps. Ideally, the riser height should range from 16 to 17cm and the tread depth from 28 to 30cm to feel comfortable when climbing a staircase. The floor height defines the number of steps needed with an optimal riser height chosen. Then you can calculate the ideal tread depth using the formula 2h + a = 62 +/- 3cm. Can you calculate the ideal tread depth if the riser height is 16cm? 32 + a = 62, a = 30cm Mosaic Chambord is a castle located close to the river Loire in France.
