Bocce court construction looks simple from above: a long rectangle, a border, a flat surface. Underneath, a good court is a layered base that drains, stays level and resists settling. The surface you pick, oyster shell, decomposed granite or synthetic turf, changes how the ball rolls, but the base and border decide whether the court still plays true after a few winters. If you want the layering and leveling handled by people who build flat, well-drained surfaces for a living, the installers the Sports Turf Manager installation team works with include crews experienced in courts and greens.
Bocce court construction: dimensions and layout
Official courts measure roughly 4 by 27.5 meters, about 13 by 91 feet. Residential courts are almost always shorter: 10 by 60 feet fits many suburban yards, and 12 by 70 gives more room for bank shots. Length changes the game more than width; below about 50 feet, rolls get too short to reward touch.
| Court type | Width | Length | Notes |
|---|---|---|---|
| Regulation | 13 ft (4 m) | 91 ft (27.5 m) | Used for tournament play |
| Club or community | 12 ft | 76 to 91 ft | Common at parks, wineries and clubs |
| Backyard | 10 to 12 ft | 50 to 70 ft | Fits most residential lots |
| Compact | 8 to 10 ft | 40 to 50 ft | Small yards; fast, short game |
Orient the court so players do not face low sun at the usual playing time, and leave at least 3 feet of walkway on each side.
Bocce court materials: what a court is made of
From the bottom up, a typical court uses:
- Geotextile fabric over the subgrade to separate soil from stone.
- Drainage layer of 3 to 4 inches of 3/4 inch clean crushed stone, sometimes with a perforated pipe along the low edge.
- Base layer of 3 to 4 inches of road base or 1/4 inch minus, compacted in lifts.
- Border of 4×6 or 6×6 timbers, composite lumber, steel edging or a concrete curb, set 4 to 6 inches above the surface.
- Playing surface of oyster shell, decomposed granite, clay court mix or artificial turf.
- Backboards of rubber or wood on the end walls to absorb impact.
Drainage is the layer people skip, and the one that separates a court that stays flat from one that heaves and puddles.
How to build a bocce court step by step
- Lay out and excavateStake the corners, square them by measuring diagonals, and dig 8 to 12 inches below the planned surface.
- Grade and compact the subgradeSet a slight fall (about 1 percent) toward the drainage side and compact with a plate compactor.
- Install fabric and drainage stoneRoll out geotextile, then spread and compact 3 to 4 inches of clean stone, with a perforated pipe at the low edge if the site holds water.
- Set the borderAnchor timbers or edging with rebar pins, top edge dead level around the full perimeter. The border is the screed guide for everything above it.
- Build the base in liftsAdd road base in 2 inch lifts, dampen and compact each. Finish 2 to 3 inches below the border, checked level with a straightedge or laser.
- Add the playing surfaceScreed shell or DG level off the border, dampen and roll. For turf, add and compact a fine leveling course, then lay and secure the turf.
- FinishAttach backboards, mark lines and roll or brush. Let a shell or DG court settle under light play for a week, then top up and re-roll.
Pro tip: a bocce court needs to be level, not sloped, on the surface. Put the drainage fall in the subgrade and stone layer, then build the base and surface flat off the border.

Oyster shell vs decomposed granite vs artificial turf for a bocce court
Each surface has a different feel, roll speed and upkeep rhythm.
| Surface | Ball roll | Upkeep | Best for |
|---|---|---|---|
| Crushed oyster shell | Traditional, medium-fast, true after rolling | Rake, dampen and roll regularly; top up yearly | Purists, clubs, dry climates |
| Decomposed granite | Firm, fast; can get dusty or hard | Rake and roll; weed control; fines wash in heavy rain | Southwest yards, lower upkeep than shell |
| Clay court mix | Slower, grips the ball, very traditional | Daily moisture management | Dedicated clubs with staff |
| Artificial turf | Consistent, slightly slower; infill level sets speed | Brush and rinse; no raking or rolling | Homes, wet climates, multi-use spaces |
Artificial turf for a bocce court has become common at homes because it plays the same after a storm as in a drought and needs no raking or rolling. Use a short, dense pile of about 1/2 inch, the same category used for a backyard putting green, with sand infill brushed in to set the roll speed. Longer landscape pile slows the ball too much. Because court widths run 10 to 13 feet, the surface can often be laid from single turf rolls with no lengthwise seam, which keeps the roll perfectly consistent.
Where professional bocce court installation pays off
Most of the work in a bocce court is grading and compaction, and that is where DIY builds go wrong. A base compacted unevenly settles unevenly, and a court a half inch low in one corner sends every ball drifting the same way. Out-of-level borders make the screed inaccurate, and skipped drainage stone leaves soft spots that become dips.
Experienced crews bring a laser level, a compactor sized to the lift and the habit of checking flatness after every layer. For turf courts they also handle the leveling course, edge fastening and infill grading that set how true the ball rolls. Ask installers about their court and green work and how they check level. You can connect with experienced local crews through professional turf installation and have them plan the full build, not just the top layer.
Bocce court construction FAQ
What is a bocce court made of?
A bocce court is layers: geotextile, a crushed stone drainage layer, a compacted aggregate base, a rigid border, and a playing surface of oyster shell, decomposed granite, clay mix or short-pile artificial turf.
How deep do you dig for a bocce court?
Plan on 8 to 12 inches of excavation: roughly 3 to 4 inches of drainage stone, 3 to 4 inches of compacted base, and 2 to 3 inches of playing surface, with the border set above grade.
Can you build a bocce court on a slope?
Yes, but the court itself must be level. The slope is handled by cutting into the high side, building up the low side with compacted base and a taller border, or adding a small retaining edge.
Is artificial turf good for a bocce court?
Short, dense putting-green style turf with sand infill gives a consistent roll with little upkeep. Standard lawn turf is too tall and slows the ball.
