Plans for a set of stairs for the front of a new community center use the ratio of rise to run of 2 units to 5 units.

a.are these stairs within carpenters guidelines,which state that the ratio of rise to run should be between 0.45 and 0.60

 

Hi Tia,

If the ratio of the rise to the run were 3 to 5 then that is 3/5 = 0.6 which is just inside the acceptable range. You have a ratio of 2 to 5. Is that in the acceptable range?
