So I'm trying to design a stair railing and I have to have the spaces between the bars to be 4". I just can't think of the way to do the math that would tell me how wide the bars would have to be.
My bars are more like panels.
Railing length: 15' 7 3/16" Design wants: I want one of the ends of the railing to end with a bar/panel. I would like the panels to have a min width of 2".
