Best Answer: 600mm is the minimum width only if the stair allows access to one room (normally an attic stair) If it is more than one room then the minimum width is 840mm, but 860 is more standard. These sizes ignore intrusions like stringers, skirting and newels. So from wall to handrail.
by Sean O'Hara on. I received a question about stair width from one of our clients and thought it made sense to clarify the typical stair design rules for houses. These are the rules that are in the 2006 International Residential Code. Stairways have to be at least 36â³ clear width above the handrail height.Handrails canât project more than 4.5â³ into each side. You need at least 80â³ of head height throughout the stair. The maximum height of a riser is 7.75â³ and the treads have to be at least 10â³ deep.Treads also need to be a minimum of 4â³ tall.tairways have to be at least 36â³ clear width above the handrail height.
