Bar Stool Height Guide

There should be an 11" to 13" space between the seat of the stool or chair and the table surface.

To determine how many stools you need to fit your bar or counter, measure the length of the bar in inches and divide by 24. You should allow 24" of counter length per stool, with or without a back. Example: You would need four stools for an 8' counter.
