Most garden measuring guides stop at a single rectangle and one tape measure. If you buy turf for a living—contractor, landscape designer or project buyer—you need more than a homeowner’s twelve steps. You need a take-off the factory can price. The zoning method below shows how to measure your garden for artificial grass the contractor way, zone by zone.
Our team plans turf for balconies, rooftops, front yards and back yards on one site. We split each space into measurable zones and build one take-off sheet the order is cut from. The steps below turn that habit into a checklist you run before ordering.
What You Need Before You Measure
We start every site visit with the same short kit. A 30 metre steel tape gives straight, non-stretching readings; a cloth tape sags, so leave it for fabric. Graph paper and a calculator turn readings into a plan.
On large sites a measuring wheel speeds long edges, but check it against the tape at each visit. A standard kit lets two crews re-measure and return the same numbers.
Sketch the Garden Into Measurable Zones
Draw the garden to scale on graph paper before the tape touches ground. Break it into rectangles, squares and triangles you can measure one by one.
Mark hard surfaces as subtract items: patios, paths, planters and tree rings take no turf. Note doors, drains and obstacles, which decide roll direction and seam placement.
A multi-area project becomes three separate zones, each measured and priced on its own. The zone method is the backbone of how to measure your garden for artificial grass with several spaces.
Measure a Simple Rectangle or Square
A rectangle is the base unit for every other shape. Multiply length by width in metres to reach the area, and measure all four sides because a fence line is rarely square.
Take the longest and widest points and multiply them to enclose the space. Working in metres keeps the final number in square metres.
Round corners hide inside that bounding box, so the priced rectangle is larger than the neat shape. A small over-measure beats a short delivery.
Break an L-Shaped Garden Into Zones
An L-shape is two rectangles that share a corner. Measure each arm, multiply length by width, then add the two areas.
Example: a 3 by 4 metre arm gives 12 m² and a 2 by 5 metre arm gives 10 m², so the L totals 22 m². Keep a little offcut where the arms meet and treat them as separate zones.
Measure Triangles, Curves and Stepped Areas
A triangle is half its base times its height. Curves and circles are easier as a bounding box: draw the largest rectangle that holds the shape, then cut the excess.
Stepped areas break into one rectangle per level. Think of a curved garden like a suit of cloth: the box is the fabric, the shape is the pattern, and the offcut is the scrap you pay for. Raise the wastage margin as the shape gets rounder.
Handle Multiple Separate Areas on One Site
A single project often spreads across several detached spaces: a front yard, a back yard and a rooftop terrace. Give each its own zone, measure it alone, and apply its own wastage margin.
Do not mix dye lots across zones. A front yard from one batch and a back yard from another can show a faint line where they meet, so lock one batch colour card for the whole site.
Read the Maximum Width and Length Correctly
Always read the maximum width and length, never the average. A short side leaves a gap if you trust the smaller.
On angled edges add a diagonal measure to draw the shape to scale. The maximum bounding box is your only insurance against a short order.
Turn Measurements Into Square Metres
Add the zone areas for gross square metres, then subtract the hard surfaces you marked as no-turf.
Round each zone up to a width the rolls come in: 2 m, 4 m or 5 m, or a tailor-made width. Square metres is the smallest unit a factory quotes, so see the artificial grass products page for the width menu.
Plan Roll Layout to Minimise Seams
Rolls come in 2 m, 4 m and 5 m widths, each 25 m long, with tailor-made widths when a seam would spoil the look. Pick the width that covers your area with the fewest joins.
A 2 m roll suits a narrow balcony; 4 m covers most mid gardens; a 5 m roll takes a large space in one piece. For a 6 m width lay a 5 m roll plus a 1 m cut, or two 4 m rolls.
Large areas gain most from the 5 m width, because fewer seams means fewer colour-shift lines. A tailor-made width removes the seam entirely, and turning readings into square metres makes how to measure your garden for artificial grass usable on a quote sheet.
Account for Wastage and Extra Material
Simple rectangles lose 5 to 10 percent to cuts; moderate curves push that to 10 to 15 percent; complex shapes reach 15 to 20 percent. The rounder the garden, the higher the margin you should hold.
By site size, areas under 20 m² add 5 percent, 20 to 50 m² add 7 percent, and over 50 m² add 10 percent. Over-order rather than under: the spare cuts a pet corner or a balcony strip.
Write the wastage percentage into the take-off for every zone. A missing margin causes a stop-work when a top-up arrives from a different dye lot.
Build a Per-Zone Take-Off List
One line per zone is the take-off: area in m², roll width, wastage percent, total roll length, seam count and your pile and backing. That single sheet is what you send for a quote.
Total the zones into one order and pin one dye lot across all of them. A same-batch colour card locks the shade so a later top-up still matches the first delivery.
Contractors who send a clean take-off get a build-ready quote, not a guess. A per-zone take-off is the payoff of learning how to measure your garden for artificial grass the contractor way.
Common Measuring Mistakes That Cost Money
Mistake one: pricing only the total square metres and forgetting roll width and seams, the leading cause of a short order or a pile of offcut.
Mistake two: skipping the wastage margin, so a site runs dry and the top-up lands in a different dye lot. Mistake three: ignoring curves and obstacles, where real cuts far exceed the neat estimate.
Mistake four: laying pieces in mixed pile directions draws a colour-shift line no brush hides. Our bench treats these four as the difference between a quote that holds and a job that reopens. These mistakes are why a careful how to measure your garden for artificial grass routine pays for itself.
Source Turf Direct From the Factory
Factory-direct supply lets you spec the turf to the job instead of bending the job to stock sizes. You set the roll width, pile height, density and backing, and the order is built to your take-off.
Measuring a Garden Full of Curves and Corners?
Odd shapes mean waste that nobody quotes for. Send the plan and we cut to width. Buying direct from the maker usually lands 30–50% below like-for-like market pricing.
Match Measurements to Roll Width and Pile
Roll width decides the seam count and pile direction the colour line, so both must match the sketch you send. A mismatch fails a first inspection.
Keep every piece on the same pile direction and one dye lot. A tailor-made width removes the seam a standard roll forces, and our line treats both as part of the spec. Matching roll width and pile to the sketch closes the loop on how to measure your garden for artificial grass, so the area passes first time.
Questions to Ask Suppliers Before You Buy
Ask for an FOB quote and a same-batch colour card before you commit, because colour drift between lots is the complaint we hear most. See the residential artificial grass and commercial artificial grass ranges to shortlist specs.
Confirm PU backing options and whether you can tailor them by zone. Check roll-width stock—2 m, 4 m and 5 m by 25 m—and the minimum order for bulk.
Request the standard 20 by 20 centimetre sample through the free samples page, and lock the dye lot before the full order. For background on the maker, see the about us page.
Frequently Asked Questions
How do I measure an irregular garden for artificial grass?
Divide the garden into rectangles, triangles and a bounding box for curves. Measure each part, sum the areas, then add a wastage margin. A zone sketch keeps the totals honest and stops you from under-ordering on awkward shapes.
What roll widths does artificial grass come in?
Widths come in 2 m, 4 m and 5 m, each 25 m long, plus tailor-made options. Choose the width that covers your area with fewest seams. A 5 m roll suits large spaces, while 2 m fits narrow balconies.
How much extra should I allow for wastage?
Allow 5 to 10 percent on simple rectangles, 10 to 15 percent on moderate curves, and 15 to 20 percent on complex shapes. Smaller sites under 20 m² add 5 percent, mid sites 7 percent, larger sites 10 percent.
How do I avoid colour mismatch between rolls?
Order every roll from one dye lot and lay all pieces in the same pile direction. A single batch colour card locks the shade across zones, so later top-ups still match the first delivery.
Can a 5m roll remove the need for seams?
A 5 m roll covers most widths in one piece, so a single run needs no seam across its width. Wide areas still join end to end, but you cut the seam count well below 2 m or 4 m rolls.
How do I get a factory quote from my measurements?
Share your per-zone areas, roll widths and wastage margin with the factory for a take-off quote. Our team returns a same-batch FOB quote with indicative pricing from $7–60 per square metre, plus a 4 to 6 day sample dispatch.
