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 balusters 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 Inch)
2. Find total space ‘occupied’ by the balus-
ters by multiplying the width of each balus-
ter 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
