How to measure for your lawn turf

To accurately calculate how much turf to order, start by drawing a diagram or quick sketch of the area on a piece of paper, be sure to include paths, gardens, pool etc. Measure the dimensions using a tape measure by walking around your yard and measuring the area of your planned lawn. Calculate the area of each shape in square metres then add the amounts together to determine the total area.

Determining your area in square metres (sqm):

Calculations to determine can be made using the following listed methods:

.

Square or Rectangle: Measure in metres the LENGTH and WIDTH of the Square or Rect angular area. To calculate, multiply the length by the width. Example: Length 10 metres & Width 5 metres - 10 x 5 = 50 square metres.

.

Circle: Measure in metres the DIAMETER of the Circular area. To calculate, multiply by 0.80 by the diameter and then by diameter again. Example: Diameter 9 metres - 0.80 x 9 x 9 = 64.80 square metres.

.

Oval: Measure in metres the LENGTH and WIDTH of the Oval area. To calculate, multiply 0.80 by the length and then by the width. Example: Length 23 metres & Width 17 metres - 0.80 x 23 x 17 = 312.80 square metres.

.

Triangle: Measure in metres the BASE and HEIGHT of the Triangular area. To calculate, multiply 0.50 by the base and then by the height. Example: Base 40 metres & height 25 metres - 0.50 x 40 x 25 = 500 square metres.

.

Trapezoid: Measure in metres PARALLEL SIDES (1) and (2) and HEIGHT perpendicular to the Parallel Sides. To calculate, multiply 0.50 by the sum of the two parallel sides and then by the height. Example: Parallel side (1) 30 metres: parallel side (2) 50 metres: height 20 metres 0.50 x (30+50=80) x 20 = 800 square metres.

.Unusual Shapes: Measure metres by firstly dividing area into sections of regular shapes ie: Circle, Square and Triangle. To calculate, apply formulas as mentioned above for each shape.

.Different Widths: Measure metres by firstly measuring the length of the longest axis across the area. Every two metres along the length line measure the width of the area at right angles to the length line. Total all widths, divide by number of width section and multiply by length. Example: Length 9 metres: width (1) 3 metres: width (2) 5 metres: width (3) 4 metres. 3+5+4=12 divide by 3 = 4 x 9 = 36 square metres.

Order additional Turf

Order up to 4% additional turf to be on the safe side. A wastage factor should be incorporated in all turf areas. This is because the minimum piece of turf used is to be 400mm x 400mm, the 4% wastage factor incorporates the lost turf in ‘cut-offs’ that are smaller than that.
