2. 16 Point Formula


Place an approximate center flag
The fringe (or 2nd cut) is included in the Total Putting Green Area
Start by placing flags at locations 1, 5, 9 & 13 to establish size
Place three flags evenly between each blue flag creating the
putting green shape

3. Measure Radius Dimensions
1…… 7.1’
2…… 8.9’
3…… 9.7’
4……10.9’
5……12.4’
6……11.7’
7……11.8’
8…… 9.9’
9…… 6.8’
10…… 8.2’
11…… 9.7’
12……10.4’
13……12.0’
14……11.4’
15…… 8.9’
16…… 8.0’
157.8’
 Measure distances in tenths instead of inches
(example: 7.5’ instead of 7’6”)
 Add the measurements & divide by 16 for the average (157.8 / 16
= 9.86’)
 Multiply the average times itself
(9.86’ x
9.86’ = 97.22 sqft)
 Multiply that total amount by 3.14
(3.14 x
97.22 = 305.27 sqft)
 Round up for the Total Putting Green Area = 306 sqft

 Every perimeter line equals 1” of elevation.
 Add in the “tiers” while you determine elevation. Indicate with
hatch lines on the green.
 Indicate distance from holes to landmark for correct placement.

6. Calculating PG turf and Fringe (2nd cut)
 The Putting Green is made up of PG turf and fringe (or 2nd cut).
 Both must be specified on the work order.
 The fringe must be a minimum of 1ft wide.
The area of the PG turf
 Determine the average width of fringe
(for this example = 1.0’)
 Take the average radius from #3
(9.86’)
 Subtract the average width of fringe
(9.86’ – 1.0’ = 8.86’)
 Multiply the number times itself
(8.86’ x 8.86’ = 78.50
sqft)
 Multiply that total amount by 3.14
(3.14 x 78.50 = 246.49
sqft)
 Round up for the total amount of PG turf = 247 sqft
The area of the 2nd cut turf
 Subtract the PG Turf from the Total Putting Green turf
59 sqft)
 Total amount of Fringe turf = 59 sqft
DOUBLE CHECK YOUR NUMBERS
 PG Turf + 2nd Cut + 3rd Cut = Total Installation Area
294 = 600 sqft)
(306 – 247 =
(247 + 59 +
