Where to Place Balusters?

Tim Healey The baluster closest to the front of the stair sits directly over the miter between the face skirt and the riser. Divide the run of the tread by the number of balusters to find the exact on-center spacing. The location of the shortest baluster on each tread determines the location of the others.

How far apart should stair balusters be?

Balusters are the vertical guards that support the handrail. They must be installed close enough that the space between them is less than 4 inches. Most city inspectors carry a 4-inch ball with them to test the spacing. Installed balusters should withstand 50 pounds of pressure exerted over a 1-sq.

How do you layout baluster spacing?

Center to Center Spacing: Simply take the tread run divided by the number of balusters per tread. So let's assume a tread run of 10 and begin with a 2 baluster per tread pattern. So we take 10 ÷ 2 = 5. Therefore the spacing is 5” from center to center of two balusters per tread.
