number of steps should be 17 or 19 ok

floor height divided by no of steps...

normally Ht of 1 Riser should be btwn 15 - 18 cms..

0.9m also essential for staircase width

normal riser should be 15cm and thread 30cm but it will vary slightly if site is doesn't have space

you do 15cm or 17cm for each step, but a stair which dont give tired feeling is your goal.

floor height/ riser height..2R+T = 60 enna formula use cheythal tread and riser proportion kitum..comfortable ayt step kayaranum pattum

16cm

Floor Ht / ht of 1 riser

riser 150 mm thread 300 mm normal
