Royal Grass® roll widths explained

What width are our lawns supplied in?

Every lawn currently in our catalogue is supplied in a 4m-wide roll. We do not stock a 2m roll, and a lawn cannot be ordered in a width that is not listed against it. The comparison table on each product page and in our product comparison shows the width held for that lawn.

Length is cut, width is fixed

The roll is made at a fixed width and cut to the length you order. That means any garden narrower than the roll is covered in one piece with trimmed waste along one or both edges, and any garden wider than the roll needs two or more strips, each cut to length.

Joins: how they are made and how they show

Strips are joined with a purpose-made tape laid under the seam and adhesive applied to both edges, with the blades brushed over the join once it has cured. A well-made join is close to invisible; a poor one shows as a line or a ridge.

• •Both strips must run in the same pile direction, or the join reads as a colour difference.
• •The sub-base must be flat across the seam, or the join lifts.
• •Joins need a full tube of adhesive and a dry day to cure.
• •Never butt strips without tape: rain, brushing and use will open the seam.

Where the offcuts come from

A 5m-wide garden covered with two 4m strips uses 5m of the second strip and leaves 3m of it unused across the full length. That surplus is not an error, it is the arithmetic of a fixed width. Planning strips along the longest dimension usually reduces it.

Offcuts are useful for small areas, shed bases, or repairs, so it is worth keeping a piece. They are rarely worth building a second lawn from.

What a join costs

Every join needs tape, adhesive, a clean cut along both edges and time to cure. On a supply-only order that is a modest material cost and an hour of care; on an installation it is part of the labour. Fewer joins is therefore cheaper as well as tidier, which is the reason the strip plan is worth ten minutes of drawing.

An example, in a 4m world

A garden 6.5m wide and 7m long needs two strips of 7m from a 4m roll: one full-width strip and one 2.5m strip, leaving 1.5m across the length unused. Ordered as one piece per strip, that is 14m of roll. Turning the strips the other way round would still be two strips, but the offcut would be the same 1.5m band, so the width, not the direction, decides the cost.

Planning the strips

1. 01

   Draw the garden and mark the roll direction

   Choose which way the strips run: along the longest dimension is normal.

2. 02

   Split the width into strips

   Divide by the roll width and round up. Confirm against the width listed for the lawn you have chosen.

3. 03

   Place the joins deliberately

   Away from paths, furniture and the middle of the view from the house.

4. 04

   Confirm with the calculator

   The grass calculator applies the roll configuration to your measurements and returns the quantity.
