What is the standard residential stair tread width?

I think my stairs are not standard.

The building regulations in the UK state that the tred of the stairs must be at least 9 inches. But of course if you have an older house then the regulations will not have applied when the house was constructed. It may of course be the rise height also that is throwing you off.

Treads too wide or too narrow don't have the right "feel". Standard tread width is thought of as some riser dimension added to some tread dimension which equals17-1/2 inches.

The width depends upon the design. If it is of lesser width,then it will be nice looking. It's standard width is of about 10-15 cms. But we cannot say this is the correct width.
