You build a pétanque court in three layers. You dig out 30 to 35 cm deep, put 20 to 25 cm of hardcore or coarse sand at the bottom for drainage, add 10 cm of crushed aggregate or dolomite as a base on top of that, and finish with a thin top layer of 1 cm of crushed gravel or grit (2 to 5 mm). A recreational court is 3 x 12 metres, an official pétanque court 4 x 15 metres. Reckon on roughly 200 to 400 euros of materials for a 3 x 12 court if you do it yourself.
Sounds manageable. And it is, as long as you keep the order and the layers right.
I have laid a few of these by now, and most problems come from two things: not digging deep enough and choosing the wrong top layer. This article saves you from both.
Below I walk you through it from A to Z. Dimensions, build-up, which gravel, drainage, edging, costs and the mistakes you are better off avoiding.
How big should a pétanque court be?
The official competition size for pétanque is 4 x 15 metres. That is how the federation plays (a court 15 metres long and 4 metres wide).
But at home you rarely need that size, and usually you do not.
For casual play in the garden, 3 x 12 metres is perfectly fine. If you want to throw with the whole family and do not have the room, a small court of 2 x 8 metres can still be good fun. You just play slightly shorter games.
Here is an overview:
| Type of court | Size | What for |
|---|---|---|
| Official (pétanque) | 4 x 15 m | Competitions, club level |
| Recreational (roomy) | 3 x 13 m | Serious garden play |
| Recreational (standard) | 3 x 12 m | The most popular garden size |
| Compact | 2 x 8 m | Small garden, family play |
My advice: go for 3 x 12 if you have the room. It plays nicely and you do not have to skimp on length.
Leave another 30 to 50 cm free all around for the edging and to be able to walk alongside it.
Where is the best place to build the court?
Pick a spot that is as level as possible. If your garden slopes, you have to move more soil and that is extra work.
Stay away from trees. After a few years roots push your court upward, and fallen leaves cause green growth and weeds.
Watch the drainage too. A court that floods after every downpour turns into a mud pit. Ground that lets water through easily is worth its weight in gold. If you are on heavy clay, a good drainage layer is extra important (more on that below).
And think about the sun. A sunny spot plays the nicest and dries out the quickest after rain.
How is a pétanque court built up?
The court consists of three layers on top of the excavated ground. From bottom to top:
| Layer | Material | Thickness |
|---|---|---|
| Drainage layer | Hardcore, crushed aggregate 0/40 or coarse sand | 20 to 25 cm |
| Base layer | Crushed aggregate 0/20, dolomite or limestone 0/10 | 10 cm |
| Top layer (dressing) | Crushed gravel or grit 2/5 mm | 1 cm |
So in total you dig out 30 to 35 cm deep. That seems like a lot, but that depth is exactly what makes the court sturdy and durable.
Do not skimp here. A court only 15 cm deep sinks unevenly and holds no water back.
I walk you through the layers step by step in a moment.
Which gravel do you use for the top layer?
For the top layer you use hard crushed gravel or grit of 2 to 5 mm.
Why crushed and not rounded? Crushed grains lock into each other and stay put. Rounded gravel grains roll away under your feet and under the boules.
The grain size determines how the court plays:
- 2 to 5 mm: calm and predictable, ideal for recreation
- 4 to 8 mm: a bit coarser and more unpredictable, for advanced players
- 8 to 16 mm scattered here and there: makes the court trickier, only if you want some bite
Choose a hard type of stone such as granite grit, crushed gravel or hard limestone. Soft stone crumbles to dust under the boules, and then within one season you are playing on a dusty or silted-up court.
And sand? No. Loose sand gives no firm base, the boules sink into it and it blows and washes away. Sand is fine as a drainage layer at the bottom, but never as a top layer.
You deliberately keep the top layer thin, 1 cm at most. Lay it thicker and the boules sink in too deep and everything rolls off in all directions.
Building a pétanque court: step by step
Step 1: Setting out and digging
Set out the court with pegs and a tightly stretched line. Check the corners with the 3-4-5 method so everything sits square.
Dig out the whole court 30 to 35 cm deep. Cart the soil off or use it elsewhere in the garden.
Level the bottom and compact it lightly with a plate compactor.
Step 2: Laying weed membrane
Lay a sheet of weed membrane (geotextile) over the excavated ground. Let it run up 10 cm at the edges.
This membrane keeps weeds down and stops the drainage layer from mixing with the ground beneath. Without a membrane, weeds grow up through your court within two years.
If you are on well-draining ground and never had water trouble, you can leave the membrane out. In practice I recommend it almost always.
Step 3: Fitting the edging
Now set a sturdy edge all around the court. It keeps the layers in place and stops boules rolling off into the garden.
You have three good options:
| Edging material | Advantage | Disadvantage |
|---|---|---|
| Concrete kerb / edging | Very sturdy, maintenance-free, lasts decades | Heavy work, less warm look |
| Treated timber (15 cm beam) | Warm, easy to fit yourself | Starts rotting after 8 to 12 years |
| Corten steel | Sleek, modern, durable | Pricier, rust water on paving |
Fix timber edges with ground anchors or stakes on the outside. Concrete you set into a lean concrete bed.
Step 4: Adding the drainage layer
Fill the tray with 20 to 25 cm of hardcore, crushed aggregate 0/40 or coarse drainage sand.
Spread it evenly and compact with a plate compactor. This layer handles the runoff of rainwater.
On heavy clay? Then dig a drainage trench 20 to 30 cm wide along the sides, filled with coarse gravel, to carry the water away.
Step 5: Adding the base layer
Add 10 cm of crushed aggregate 0/20, dolomite or limestone 0/10.
This is the load-bearing layer that makes your court level and firm. Spray it lightly wet and compact it well.
Important: for this layer use a tandem roller rather than a plate compactor if you can. A plate compactor pushes the fine parts down and the coarse ones up, and then your court turns bumpy.
Lay this layer with a slight camber: about 1 to 2 cm higher in the middle than at the sides. That way rainwater runs off to the edges by itself without you noticing it while playing.
Step 6: Dressing the top layer
Finally, scatter 1 cm of crushed gravel or grit 2/5 mm over the base.
Spread it evenly with a rake and pull it flat with a screed board. Compact very lightly, or just let it settle by playing on it.
Do not compact the top layer repeatedly. If you do, the fine parts sink away and the coarse stones come up, which looks ugly and plays uncomfortably.
Done. Let the court settle for a few days and then you can throw.
How much material do you need?
Work out per layer how many cubic metres you need. The formula is simple: length x width x layer thickness in metres = cubic metres.
For a court of 3 x 12 metres (36 m²):
| Layer | Thickness | Calculation | Cubic metres |
|---|---|---|---|
| Drainage | 0.25 m | 36 x 0.25 | 9.0 m³ |
| Base | 0.10 m | 36 x 0.10 | 3.6 m³ |
| Top layer | 0.01 m | 36 x 0.01 | 0.36 m³ |
Add another 15 to 20 percent for settling and loss. So order a little generous rather than too tight.
Rule of thumb for the top layer: reckon on roughly 0.01 m³ (10 litres) of gravel per square metre of court. For 36 m² that is around 360 litres, or half a bulk bag.
What does a pétanque court cost?
Building it yourself is a lot cheaper than having it done. Here are the realistic figures for a 3 x 12 metre court.
| Item | Do it yourself | Have it built |
|---|---|---|
| Materials (gravel, aggregate, membrane) | 200 to 400 euros | included |
| Edging | 100 to 300 euros | included |
| Machine hire (plate compactor/roller) | 50 to 100 euros | included |
| Labour | your own weekend | 1,500 to 2,500 euros |
| Total | around 350 to 800 euros | 2,000 to 3,000 euros |
Have a landscaper build it and you are looking at 2,000 to 3,000 euros on average. Choose pricier materials or corten steel and it climbs higher.
Doing it yourself easily saves you more than 1,500 euros. It is solid digging work, but well within reach over a weekend with a bit of help.
Lighting by the court
If you want to keep playing in the evening, plan the lighting right at the build stage. Run the cables before you fill the court in.
Two low lamp posts on either side give the nicest, even light. Avoid a single bright spotlight: that casts hard shadows so you can barely see the jack.
LED fittings with warm light (2700 K) give a cosy atmosphere and use little power.
How do you maintain the court?
A good court does not ask for much maintenance, but a little attention keeps it looking good.
- Rake the top layer smooth now and then, especially after heavy play. That keeps it level.
- Clear leaves and organic material quickly, that prevents growth and weeds.
- Top up the gravel where the base starts showing through, usually after a few seasons.
- Pull weeds out straight away before they root. With membrane underneath this is very minor.
- Roll the court briefly in spring if needed, to iron out winter unevenness.
Do this, and a well-built court easily lasts fifteen years or more.
Common mistakes
These are the ones I see go wrong most. Avoid them and your court plays well for years.
- Digging too shallow. Less than 30 cm and the court sinks unevenly and holds no water back.
- Rounded gravel as the top layer. Rolls away under your feet. Always use crushed material.
- Sand as the top layer. The boules sink in and it washes out. Sand belongs at the bottom.
- No weed membrane. Weeds grow up through the court within two years.
- Laying it dead flat. Without a slight camber, water pools on the surface.
- Over-compacting the top layer. Coarse stones come up, fine parts sink away.
- Choosing a soft type of stone. Crumbles to dust and silts the court up.
- Building under a tree. Roots and leaves ruin your court over time.
Frequently asked questions
How deep do you dig for a pétanque court?
Dig 30 to 35 cm deep. That is needed for the drainage layer (20 to 25 cm), the base layer (10 cm) and the thin top layer (1 cm). Any shallower and the court sinks unevenly and does not hold rainwater back.
Which gravel is best for a pétanque court?
Hard crushed gravel or grit of 2 to 5 mm. Crushed grains lock into each other and stay put, rounded gravel rolls away. Choose a hard type of stone such as granite so it does not crumble to dust. Loose sand is unsuitable as a top layer.
What does it cost to build a pétanque court yourself?
For a 3 x 12 metre court reckon on around 350 to 800 euros for materials, edging and machine hire. Have a landscaper do it and it costs 2,000 to 3,000 euros on average. So doing it yourself easily saves more than 1,500 euros.
How much room do I need for a court in the garden?
A recreational court is 3 x 12 metres. If you have less room, a small court of 2 x 8 metres also works. Leave another 30 to 50 cm free all around for the edging and to walk alongside it.
Does a pétanque court have to be perfectly flat?
Almost. Lay the court with a very slight camber: about 1 to 2 cm higher in the middle than at the edges. That way rainwater runs off without you noticing it while playing. Laying it dead flat causes puddles after rain.
Do I need weed membrane?
In most cases, yes. Weed membrane keeps weeds down and stops your drainage layer from mixing with the ground. Only on very well-draining ground without weed problems can you leave it out, but usually I recommend it.
