Baluster Centers ??
 
I'm installing a railing around a stairwell opening and don't know what the recommended spacing for the balusters should be. They are lathed balusters and posts. The railing will not be connecting to the stair railing. It leaves the wall...goes about 3.5 feet, makes a 90 at a post...then goes another 3.5 feet. The square part at the bottom measures 1.25 inches. What looks good...and what is code? Thanks!!

The code is that a 4" sphere cannot be passed thru the opening in between the ballusters. Essentially, the rule of thum is 4" center to center of each balluster. You can adjust these to a smaller 'increment' if it will help align the ballusters more evenly.

Here is a good illustrative link that shows this based on the ICC. (Even tho, it is primarily a for deck descriptions, the stair and railing code is applicable) Scribe to page # 2

Better check locally on mininum rail height also. Many localities have begun requireing residential upper railing to be 42 ", which previously had been commercial, but not residential. I personally thing this high looks ridiculous in a house, but they did not ask me first.:laughing:
