Five Fun Facts About Stair Balusters

February 10, 2016

A quick look at decorative sticks

Fun Fact 1: Stair Balusters are new

Even though they look like classic architectural elements, stairway balusters did not hit the scene until the Renaissance, in the 16th century.

Fun Fact 2: Stair Balusters are named after flowers

Balusters got their name because one type (above photo) looked like an unopened flower (below photo) and became known in Italy as a “balaustra” which means “pomegranate flower.”

Fun Fact 3: Stair Balusters have evolved

Back then, balusters were made out of marble or bronze, whereas today they’re usually wood or some kind of stone.

Looking at a baluster is a great way of figuring out when a structure was built since their sizes and styles have changed so much over the years.

Fun Fact 4: Stair Balusters vary

Two common baluster installations today are tread-oriented and rail-oriented. In the first case, the balusters are placed corresponding to the tread. This makes the ornamental sections sit level to each other:

In a rail-oriented installation, the ornamentation is parallel to the handrail, which means the decorative areas are at a slope:

Some stairways have two balusters per tread, and some have three.

Either way is fine, but code (2012 IRC: R311.7 Stairways) mandates that balusters must be placed no more than 4” apart to prevent a young child’s head from becoming caught in the space.

Fun Fact 5: The choice is yours

For Professional Remodeler's 2015 Model Remodel, the homeowner chose a tread-oriented installation.
