As an estimator I'm increasingly figuring stair parts and balusters. I really need to be accurate so would one of you guru's give me your formula? For ex: Lets say I have a 91" run wall to Newel, and I have 9/16" round balusters. Thanks in advance.

Yes I did. Balusters vary in width from wood to iron. I easily recognize the max 4" spacing. I'm simply trying to get a formula that takes into acct the baluster width and gives eq spacing to the newel. Why act like an ass?

Almost. The formula is (run + width of one baluster) divided by (maximum spacing + the width of one baluster).
91.5625/4.5625 =20.068. Round up to 21.
Then, 91.5625/21= 4.36 which is roughly 4 3/8".
Now just hook the end of the run and lay out every 4 3/8" with the x to the left, just like laying out wall plates.

Repetitive member spacing equation

Repetitive member spacing equation

(Run +width of one member) / (maximum spacing + width of one member) then round up. = number of spaces
Then. (Run + width of one member) / number of spaces = (space + width of one member)
Number of spaces - 1 = number of members
