Lawn Area Calculator
Measure your lawn in square metres by breaking it into simple shapes. Take away garden beds and paths, then save the area to your Lawn Journal.
Tools
Calculators that use your lawn area and the rate on the product label, plus pickers and identifiers. They work on your phone, standing on the lawn.
Product Application Calculator
Enter your lawn area and choose a product to see how much product and water you need, using the rate from the product label. No label rate on file? Enter it from the label yourself.
Sprayer Calibration Calculator
Find out how much water your sprayer and walking pace actually put out, so you can match the water volume on a product label.
Spreader Calibration Helper
Check what your spreader puts out per square metre at a given setting, and whether to open it up or close it down to match the label rate.
Topdressing Calculator
Work out how many cubic metres (and roughly how many tonnes) of topdressing you need from your lawn area and depth.
Turf and Seed Calculator
How much turf to order with an allowance for cutting, or how much seed to buy from the sowing rate on the bag.
Sprinkler Run-Time Calculator
Turn the results of a catch-cup test into how many minutes to run each sprinkler zone, and see how evenly your sprinklers water.
Grass Type Picker
Choosing a new lawn? Tell us about sun, wear, climate and how much maintenance you want, and see which grass types suit.
Weed Identifier
Work out what's growing in your lawn, step by step. Answer questions about the leaves, flowers, season and growth habit.
Cost and Coverage Calculator
How many applications does a pack cover for your lawn, and what does each application cost?
