One tennis court is 260.76 m² of playing surface, 592.84 m² of turf at the club run-off tier, and 8 rolls of 4 m. A block of four is 1,970.47 m² and 20 rolls. A block of eight is 3,789.27 m² and 40 rolls. The three areas are not one area multiplied out.
The difference is the gap between the courts: adjacent tennis courts share one strip of run-off, 3.66 m at minimum, instead of two full side buffers. We cut tennis court turf at 2, 4 and 5 m wide by 25 m long. Every figure here can be re-run against a real roll and a drawing.
One Court, Four Courts, Eight Courts: Start With the Numbers
260.76 m² is the playing surface inside the lines — 23.77 by 10.97 m, measured to the outside of the lines, paint included. 592.84 m² adds the club run-off tier: 5.48 m behind each baseline, 3.05 m at each side. The carpet then runs 34.73 by 17.07 m. 668.87 m² is the international tier, 36.57 by 18.29 m.
The rolls come from the same rectangle. The club court lays out as 5 strips on 4 m rolls. Each strip is a full 25 m piece plus a 9.73 m tail, and the tails nest two per roll — 8 rolls, 800 m² ordered.
- One court: 592.84 m² of turf, 8 rolls of 4 m.
- Four courts in a 2×2 block: 1,970.47 m² and 20 rolls — the shared gaps do the saving.
- Eight courts in a 4×2 block: 3,789.27 m² and 40 rolls, 473.7 m² per court, 79.9% of a standalone one.
What the ITF Fixes, and What It Leaves to You
The rulebook fixes less than buyers assume, and every tennis court turf count inherits it. The ITF Rules of Tennis lock the rectangle at 23.77 m by 10.97 m for doubles and 8.23 m for singles. Lines run 2.5 to 5 cm, the baseline up to 10 cm.
All court measurements run to the outside of the lines, so 260.76 m² already contains the paint. A take-off that adds line area back in double-counts it — the most common error in this chain. Badminton court dimensions follow the same convention: the quoted figure is the figure you buy.
The rectangle and the lines
Rule 1 also fixes the furniture: net posts 0.914 m outside the doubles sideline, service lines 6.40 m from the net. None of it adds a purchasable square metre.
What the rulebook does not say
Run-off appears only as an “as a guide” recommendation, and the book says nothing about seams, pile height or roll width. Buying by the standard therefore stops at the line; everything past it is a tier choice.
Two Run-Off Tiers, Plus the Stadium Case
Run-off is paving width, not spare ground: the guidance reads “from each baseline to fence”. The club and recreational tier sets 5.48 m behind each baseline and 3.05 m at each side — 34.73 by 17.07 m, or 592.84 m². Tennis Australia’s facility planning guide states both values and adds the phrase that makes them purchasable: the run-off runs to the fence.
The international tier sets 6.40 m behind each baseline and 3.66 m at each side — 36.57 by 18.29 m, or 668.87 m². The stadium tier reaches 8.23 m and 4.57 m, 40.23 by 20.11 m and 809.03 m². It appears once, here only.
Run-off adds 332.08 m² per court at club level and 408.11 m² at the international tier. Stepping up one tier costs 76.03 m² per court, and the next step 140.16 m² more.
5.48 or 5.49? The ITF prints 5.48 m for the club run-off and Sport England prints 5.49 m. One centimetre is 0.34 m² on a single court and about 2.7 m² across an eight-court block. This page holds 5.48 m throughout.
Shared Run-Off: Why a Block of Four Wins
Adjacent courts do not need two sets of side run-off. Sport England’s comparative court sizes state it verbatim: a shared run-off between adjacent courts is 3.66 m minimum or 4.27 m preferred. The published two-court example prints 34.75 × 31.77 m; this page computes 2 × 10.97 + 2 × 3.05 + 3.66 = 31.70 m from the buffers instead. The 0.07 m is rounding in the printed table; 31.70 holds throughout.
The block arithmetic is one formula per direction. Length equals courts × 23.77 + 2 × 5.48 + (courts − 1) × 3.66, and the width follows the same shape across the rows. The official example covers side-by-side blocks only; the end-to-end use of the same gap is an extension, marked as derived.
| Courts / layout | Club block | Club area | ITF block | ITF area | Per court (club) | Saved vs separate |
|---|---|---|---|---|---|---|
| 1 | 34.73 × 17.07 m | 592.84 m² | 36.57 × 18.29 m | 668.87 m² | 592.8 m² | — |
| 2 (1×2) | 34.73 × 31.70 m | 1,100.94 m² | 36.57 × 33.53 m | 1,226.19 m² | 550.5 m² | 84.74 m² |
| 4 (2×2) | 62.16 × 31.70 m | 1,970.47 m² | 64.61 × 33.53 m | 2,166.37 m² | 492.6 m² | 400.89 m² |
| 6 (3×2) | 62.16 × 46.33 m | 2,879.87 m² | 64.61 × 48.77 m | 3,151.03 m² | 480.0 m² | 677.17 m² |
| 8 (4×2) | 62.16 × 60.96 m | 3,789.27 m² | 64.61 × 64.01 m | 4,135.69 m² | 473.7 m² | 953.45 m² |
The savings column is the point. Two club courts save 84.74 m²: one gap replaces two 3.05 m side buffers, 2.44 m of width across 34.73 m. The same gap saves 111.54 m² at the international tier. Four courts save 400.89 m², sharing in both directions. Eight courts save 953.45 m², and per-court turf falls to 473.7 m², 79.9% of a standalone court.
The familiar shortcut, one court multiplied by the number of courts, over-buys 400.89 m² at four and 953.45 m² at eight.
What a shared gap cannot carry
The sharing clause carries one condition: no fence or other obstruction between the courts. Floodlight poles set in the gap still need 3.66 m clear. A block therefore saves carpet only; fencing, lighting bases and drainage stay per-court. The 79.9% is a turf figure, not a project figure.
Roll Width, Strip Direction and the 25 Metre Limit
No tennis frame fits one 25 m roll. Every strip is a full 25 m piece plus a tail: 9.73 m on a club court (34.73 m long), 11.57 m on an international one. Blocks run longer still — 62.16 m and 64.61 m — with tails of 12.16 m and 14.61 m. Width decides the strip count: the club court is 17.07 m wide, which is 4 strips of 5 m, 5 of 4 m or 9 of 2 m.
Nesting is one division: tails per roll equal 25 divided by the tail length, rounded down. A 9.73 m tail nests two per roll, and so do 11.57 m and 12.16 m tails; a 14.61 m tail nests one. The club court on 4 m rolls is therefore 5 full rolls plus 3 tail rolls. The same division decides how many rolls a netball court needs, tail arithmetic and all.
- One club court: 8 rolls of 4 m, 800 m² ordered — 34.9% over the 592.84 m² it covers.
- Four courts, 2×2: 20 rolls, 2,000 m² — 1.5% over 1,970.47 m². The 62.16 m block reads 2 × 25 + 12.16, and two 12.16 m tails fit inside one roll.
- Eight courts, 4×2: 40 rolls, 4,000 m² — 5.6% over 3,789.27 m².
Block length flips the order. The international four-court block reads 2 × 25 + 14.61, and its tail no longer nests: 14.61 × 2 = 29.22 m, past the limit. Every strip therefore takes two full rolls plus a single tail piece. Nine strips at three pieces come to 27 rolls and 2,700 m² — 24.6% over the 2,166.37 m² the block covers. A 2.45 m difference in block length turns the cheapest width into the dearest order.
Direction matters before width does. On a two-court block, 5 m rolls take 11 laid across the width and 10 along the length. The 6.70 m tails nest three per roll that way, against two. A tennis court turf order is a stack of strips first and an area second.
Turn the layout before you change the width. On a single court, 5 m rolls carry 26.5% of surplus and 4 m rolls 34.9%. On a four-court block the same swap runs the other way, from 14.2% down to 1.5%. Width has no general winner, only a fit with the block.
Does Your Block Length Fit a 25 Metre Roll?
Our line cuts roll width and length to the block schedule, so a 14.61 m tail never buys a whole roll. It runs 2, 4 and 5 m formats.
Where the Seams Land Matters More Than How Many
No published rule fixes seam positions on a tennis court; the 25 m grid does. The only official clause is visual: the court should show a uniform appearance with no gaps between joins. Counting them is strip arithmetic — longitudinal seams are strips minus one, transverse seams are strips times pieces minus one. The same counting runs through cricket outfield roll counts, where a curved boundary replaces the rectangle.
- One club court on 4 m rolls: 9 seams — 4 longitudinal and 5 transverse.
- Four courts in a 2×2 block: 23 — 7 longitudinal and 16 transverse, two cuts per strip across 8 strips.
- Eight courts in a 4×2 block: 47 — 15 longitudinal and 32 transverse; the same block on 2 m rolls reaches 92.
Position is a layout decision, not a compliance one. The plain 25 m cut puts the transverse seam 4.25 m before the far baseline, 19.52 m in. That band is where the first ball after service lands. Cutting 5.48 + 23.77 + 5.48 instead moves both transverse seams onto the 10 cm baseline carpet, for the same 8 rolls.
The three-piece plan costs five more seams, 9 becoming 14. Decide where seams are allowed before counting them. No clause forbids a seam in the service boxes, but a layout that avoids them avoids the busiest landing zones.
Short Pile, Sand Rate and the Tonnage Behind It
Tennis runs on short carpet. The LTA’s porous court surfaces guidance puts tennis yarn at medium or short pile, 15 mm down to 10 mm.
Court speed becomes a function of yarn density, pile length and sand fill together. No single official height exists. The tier table in tennis court turf specifications carries the options; this section carries the two buying numbers.
Sand turns the area into tonnage. The published tiers put the medium pile at 15 kg/m² and the short pile at 8–10 kg/m². The 15 kg/m² rate is the tennis value; other sports run lighter. At 15 kg/m² the club court carries 8.89 t, the four-court block 29.56 t and the eight-court block 56.84 t.
- Pile height: 10–15 mm, medium or short.
- Sand rate: 15 kg/m² medium, 8–10 kg/m² short.
- Tonnage at 15 kg/m²: 8.89 t, 29.56 t and 56.84 t across one, four and eight courts.
Waste Follows the Layout, Not a Percentage
No official waste rate exists for tennis court turf. A turf calculator defaults to 8%, with 3% minimal and 20% for complex sites; an installation guide says 5–10% extra. The rates that matter here are the ones the layouts above already carry, each derived from a 25 m roll plan.
The strip plans carry their own margin. A single court orders 800 m² against 592.84 m² of carpet, +34.9%. The four-court block orders 2,000 m² against 1,970.47 m², +1.5%, and the eight-court block 4,000 m² against 3,789.27 m², +5.6%. Each percentage divides the order by the turf footprint, never by the line-enclosed area.
A rate on a nested plan buys the same offcut twice. Adding 8% to the four-court order suggests 2,128.11 m² against the 2,000 m² the rolls already contain, and 3% suggests 2,029.58 m². That is a 98.52 m² spread (rounding aside) between two defaults, and 128.11 m² of it is double-counted against the plan.
The decision rule is geometric: three percent fits a clean rectangle with no cut-ins. Eight percent fits cut-ins, returns and layouts past ten seams. Twenty percent fits non-rectangular sites with obstacles. Compute the strips and tails first, then decide whether any rate is needed at all.
What to Put on the Drawing Before You Ask
A tennis court turf drawing returns a roll schedule when it carries seven lines, and returns assumptions when it carries only an area. Every line below traces back to a number above.
- Court outline, 23.77 × 10.97 m, noting that dimensions run to the outside of the lines.
- The chosen run-off tier: 5.48/3.05 m club, 6.40/3.66 m international, or 8.23/4.57 m stadium.
- Court count and arrangement — 1×2, 2×2, 3×2 or 4×2 — with the shared gap width, 3.66 or 4.27 m.
- Overall block dimensions, 62.16 × 31.70 m rather than an area; roll counts only come from length and width.
- Roll width and laying direction, plus where seams are allowed; the tennis turf systems page separates standard widths from cut-to-order lengths.
- Sand rate tier, 15 or 8–10 kg/m², and the total tonnage.
- Delivery port and project location, which are trade terms rather than technical inputs.
Area cannot produce a roll count; length and width can.
Frequently Asked Questions
How much artificial grass does a tennis court need?
One court is 260.76 m² inside the lines, 592.84 m² of turf with club run-off and 668.87 m² at the international tier. The first figure is never the order.
How many rolls of turf does a tennis court need?
On 4 m rolls: 8 rolls for one club court, 20 for a 2×2 block, 40 for a 4×2 block. The count comes from strip and tail arithmetic.
Do adjoining tennis courts share their run-off?
Yes. The shared gap is 3.66 m minimum or 4.27 m preferred, and a 2×2 block of four saves 400.89 m² against four separate footprints.
What run-off does an ITF tennis court need?
6.40 m behind each baseline and 3.66 m at each side, against 5.48 m and 3.05 m for club play. Both are recommendations, not mandates.
How much sand does a tennis court take?
At the medium-pile rate of 15 kg/m², one club court carries 8.89 t of sand and a four-court block 29.56 t. The short-pile tier runs 8–10 kg/m².
Where should the seams go on a tennis court?
No rule fixes seam positions. Where the layout allows, move transverse seams onto the 10 cm baseline carpet; the plain 25 m cut otherwise lands one 4.25 m inside the backcourt.
