Baluster Spacing
You are going to install a handrail at the top of a balcony. Your total
Span is 156 Inches and you would like the space between the balus-
ters to be about 4 Inches. If each baluster is 1-1/2 Inches wide, what
is the exact spacing between each baluster?

1. Estimate number of balusters in Span:
oo 0.
156i÷ 156 INCH
5i1/2=* 28.36364 (28 balusters)
*desired spacing plus baluster width (4 Inches plus 1-1/2 Inches).
2. Find total space ‘occupied’ by the balusters by multiplying the
width of each baluster by the rounded number of balusters (found
above):
1i1/2x 1-1/2 INCH
28= 42 INCH
3. Find total space between all balusters:
156i– 156 INCH
42i= 114 INCH
4. Find actual baluster spacing by dividing total space between all
balusters by the number of spaces between the balusters (number
of balusters plus one equals 29):
114i÷ 114 INCH
29= 3-15/16 INCH
