Tip: every iron baluster needs a base shoe to cover the hole at the tread. Match the shoe to your bar size. Shop base shoes →

How many balusters do I need?

Building code requires gaps under 4". Most stairs use 2 balusters per tread, or 3 for a tighter look.

26 balusters + 26 base shoes

Balcony runs use about 3 balusters per foot. Order 1–2 extra for cutting mistakes.

Hollow vs. solid

Hollow (lightweight) balusters cost less and are easier to cut and install. Solid bars feel heavier and suit high-traffic or commercial stairs. Both look the same once installed.

Pick your bar size

1/2" is the most common and fits most homes. 9/16" and 5/8" look a bit fuller. 3/4" "Mega" bars make a bold modern statement. Keep one size throughout your staircase.

Choosing a finish

Satin Black is our best seller and matches almost any décor. Oil Rubbed Bronze and Copper add warmth with wood treads. Ash Gray suits light, coastal and modern interiors.

Mix for a custom look

Alternate a plain bar with a twist, knuckle or basket every other spot. It's an easy way to get a designer look on a budget.

Base shoes (one per baluster), epoxy or construction adhesive, and a few set screws. We carry all of it, so you can get everything in one order.
