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?
KEYSTROKE DISPLAY
1. Estimate number of balusters in Span:
o o 0.
1 5 6 i ÷ 156
INCH
5 i 1 / 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):
1 i 1 / 2 x 1-1/2
INCH
2 8 = 42
INCH
3. Find total space between all balusters:
1 5 6 i – 156
INCH
4 2 i = 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):
1 1 4 i ÷ 114
INCH
2 9 = 3-15/16
