how much grass do i need?
option A: Google Maps
Head to Google Maps and use their easy Measuring Tool to get an
accurate measurement of your space. Add 10% for contingency.Not sure how to use Google Maps? No worries, check out our quick
explainer video here for a quick how-to, it’ll only take a minute!

option b: old school style - measure by hand
Sketch it: create a rough yard sketch.
Shape it up: break down complex areas into simple shapes.
Measure up: use the calculations below to determine your turf requirements, add them up, and voila! You've got your precise turf measurements. But just in case, we suggest adding an extra 10% for contingency.

Square / Rectangle:
Length x width = m2
e.g. 5m x 5m = 25m2
Circle:
(Radius x radius) x 3.14 = m2
e.g. (3m x 3m) x 3.14 = 28.26m2
Semi-circle:
Circle calculations (left) / 2 = m2
e.g. 28.26m2 / 2 = 14.13m2
Triangle:
(Length x width) / 2 = m2
e.g. (10m x 5m) / 2 = 25m2
Unusual Shapes:
Sketch your yard, break it into shapes and use shape calculations above.
e.g. rectangle + square + triangle = m2
Varying Widths:
Measure the longest edge (length)
Divide the widths into 2m sections and measure (width 1, 2, 3, etc.)
Calculate (width 1 + width 2 + width 3) / number of width sections
Multiply by length
e.g. ((5m + 6m + 6m + 7m + 8m)/5) x 10m = 64m2
5. Add a few extra m2 per 100m2 as a buffer
