Enter the measurements of your area —even if it has several zones— and we'll work out the total square metres, the recommended cutting allowance, and which models suit your case.
Divide the area into rectangles. For curved shapes, use the rectangle that contains them: if you leave a cutting allowance, it will cover the trim.
You almost never use 100% of the roll: the more irregular the area, the more allowance it's worth leaving. If your measurements already include the trim, choose "No allowance" and you'll order exactly the metres you've noted down.
This lets us filter the catalogue and show you below only what fits.
Prices calculated for your 20 m² with a 10% cutting allowance. Choose a model and add it to the basket without entering the measurements again.

Most buying mistakes come from underestimating the measurements. These are the questions we get asked most.
If you'd rather measure by hand and understand where each figure comes from, read how to calculate the m² you need.
Multiply the length by the width of each area in metres and add up the results. Then add between 5% and 15% to cover cuts, joins and corner adjustments. For example, an area of 5 × 4 m is 20 m²; with a 10% allowance, you should order 22 m². The allowance is optional: if your measurements already include it, choose «No allowance» and you'll order exactly the metres you've noted down.
Because the grass comes in rolls of a fixed width (2 or 4 metres) and has to be cut to fit your shape. That cutting produces offcuts that can't be reused. What's more, all rolls must be laid with the fibre running in the same direction, which sometimes means wasting material to avoid visible joins.
Split it into rectangles and add them up. For curved or triangular areas, measure the rectangle that contains them and use a 15% allowance: it's cheaper than running short, because a later top-up may come from a different production batch and the difference in shade can show.
In a well-planned installation, between 3% and 8% of the material. Keep the larger offcuts: they're useful for repairing a damaged area years later in exactly the same shade.
Only if they are large, regularly shaped features. It's not worth subtracting a single tree or a small flower bed: cutting around them creates more waste than it saves, and running short is the worst outcome.
