Enter Lawn shape, Length / diameter / base, Width / height (rect & triangle), Waste allowance (%), Price per pallet (optional) and the Sod calculator works out Area, Slabs (2.67 sq ft), Rolls (10 sq ft), Pallets (450 sq ft), Estimated cost straight away. For instance, with Lawn shape = Rectangle, Length / diameter / base = 12 m, Width / height (rect & triangle) = 7.5 m, Waste allowance (%) = 5 and Price per pallet (optional) = $0.00 it returns Area = 94.5 m², Slabs (2.67 sq ft) = 381 and Rolls (10 sq ft) = 102.

How to use it

  1. Enter your values: Lawn shape, Length / diameter / base, Width / height (rect & triangle), Waste allowance (%), Price per pallet (optional).
  2. Read the result instantly: Area, Slabs (2.67 sq ft), Rolls (10 sq ft), Pallets (450 sq ft), Estimated cost.

Frequently asked questions

What does the Sod calculator actually compute?

It takes Lawn shape, Length / diameter / base, Width / height (rect & triangle), Waste allowance (%) and Price per pallet (optional) and derives Area, Slabs (2.67 sq ft), Rolls (10 sq ft), Pallets (450 sq ft) and Estimated cost from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

5 values: Lawn shape, Length / diameter / base (m), Width / height (rect & triangle) (m), Waste allowance (%) and Price per pallet (optional) ($). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Lawn shape = Rectangle, Length / diameter / base = 12 m, Width / height (rect & triangle) = 7.5 m, Waste allowance (%) = 5 and Price per pallet (optional) = $0.00, the calculator returns Area = 94.5 m², Slabs (2.67 sq ft) = 381 and Rolls (10 sq ft) = 102. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Lawn shape = Circle, Length / diameter / base = 13 m, Width / height (rect & triangle) = 8.25 m, Waste allowance (%) = 10 and Price per pallet (optional) = $5.00 instead, Area goes from 94.5 m² to 146.006 m² — which is why it is worth testing a few scenarios rather than trusting a single figure.

Which “Lawn shape” option should I choose?

You can pick between « Rectangle », « Circle » and « Triangle ». Each one changes what the calculator works out, so switch and compare — the default is « Rectangle ».

Which units should I enter the values in?

Enter Length / diameter / base m and Width / height (rect & triangle) m. Metric and US units are both supported — switch system and the figures convert for you.

What does it give for smaller values?

Scaled down to Lawn shape = Rectangle, Length / diameter / base = 11 m, Width / height (rect & triangle) = 6.75 m, Waste allowance (%) = 3 and Price per pallet (optional) = $1.00, Area comes out at 76.478 m². The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Buying the right amount at the merchant: how many tiles, how much paint, how many bags of concrete, and what it all comes to.

What is the most common mistake?

Ordering the exact calculated quantity. Every material loses some of itself between the pallet and the finished job — offcuts, breakage, a bag that sets, a coat that soaks in further than the datasheet says — so add the allowance yours asks for, and order it in one delivery: a second batch rarely matches the first.

What is the difference between the Sod calculator and the Brick calculator?

This one returns Area and Slabs (2.67 sq ft); the Brick calculator returns Bricks needed and Bricks per m². That is the whole difference — open the one whose figure you need.
