How to Build a Bocce Court With Artificial Turf

This page is for homeowners and clubs who want a bocce court that can be played the day after rain. The specs for a bocce court are split across three places: the national rules give the size, a standards group gives the boards and base, and a turf seller gives the drainage and turf tips. We put them on one page and worked them through for a backyard court.

Key takeaways

• The official US court is 86.92 x 13.12 ft. Some guides print "86.2 ft," which is a typo for the USBF figure.
• Smaller courts are allowed for casual play. Courts in the US run 60 to 100 ft long, and 60 x 12 ft fits many yards.
• Boards stand 6 to 12 inches above the playing surface, in treated lumber, backed by concrete or by 4x4 posts at 4 ft or less.
• The base is at least 3 inches of crushed stone on a compacted sub-base, finished flat. Do not crown it or slope it like a lawn.
• Use short, dense turf with a firm top. Shorter pile gives the ball more rebound and absorbs less of its energy.

What is a bocce court?

Bocce is a ball game for two sides. One player throws a small target ball, the pallino, and then each side rolls larger balls, about 2 lbs each, to finish closest to it. A bocce court is the lane they play in: a long, level strip boxed in by sideboards along the edges and backboards at each end. Players may bank balls off the sideboards at any time, so the boards are part of the game, not just a fence.

The court has painted lines too: a foul line is the line a player must not cross before releasing a ball. A center line splits the court in half, and play runs one way, then back the other way from the far end.

That is why a turf lawn is the wrong model. A lawn is built to shed water across its surface, while a bocce court has to hold a rolling ball on a straight line for 60 ft or more.

How big is a bocce court?

The two "official" lengths you will find online are 86.92 ft and 86.2 ft. The United States Bocce Federation (USBF) rules say "86.92' in length and 13.12' in width." A turf seller's guide quotes the USBF but prints 86.2 ft. Use 86.92 ft: in metric it is 26.5 x 4 m, a round figure that shows the 86.2 is a slip.

If you will never host a tournament, size the court to the yard. The Bocce Standards Association (BSA) notes that US courts run "from 60 feet to 100 feet," and its standard is 76 ft by 10 to 13 ft. Add room outside the boards for the posts and for people to stand.

Where do the foul lines go?

The two rule sets differ, so pick one before you paint.

• USBF: one line for both pointing (rolling close) and shooting (knocking balls away). It recommends that line 13 ft from the back wall, at each end.
• BSA: two lines at each end, a pointing foul line at 6 ft and a hitting foul line at 10 ft.
• Both: a center line at half the court length.

The USBF says foul lines "should be clearly marked both on court surface and side boards." The BSA asks for painted vertical lines 2 inches wide on the sideboards at the foul lines and center line.

Why use artificial turf for a bocce court?

Because the classic surface takes daily work. The BSA court is clay over stone, and it "must be wet down" to stay compacted, and it is topped with loose clay that is brushed smooth. The USBF lists many surfaces in use, including carpet, crushed stone, oyster shells, clay and "most recently synthetic carpets." Turf is an accepted surface, not a hack.

Turf drains through its backing, and a seller's guide calls a turf court "accessible even after inclement weather." It needs no watering and no topping clay, so how it plays comes down mostly to the pile.

Which turf rolls true on a bocce court?

Short and dense, like a putting green, because the Greatmats guide says "a shorter pile height will create more rebound and absorb less energy." A taller pile gives "less bounce" and absorbs more energy. The guide's most popular bocce product is a padded turf with a 9/16 inch pile that needs no infill.

Our rule is to buy from the putting turf aisle. Putting green turf runs about 3/8 to 3/4 inch pile, built so a ball rolls across the fiber tips. Here, pile height means the length of the fibers above the backing. Lawn turf over an inch grabs the ball and slows it unevenly.

Padded or infilled is the next choice, and a padded product skips the infill, which Greatmats says keeps cost down. Sand infill works too, but loose sand drifts around the surface. On a putting green, sand piles speed up or slow down the ball in spots, and a bocce ball reacts the same way. If you infill, brush it in evenly and top it up where players stand.

What base does a turf bocce court need?

The BSA says to build it "similar to standard tennis courts," with "a minimum 3 inch base of crushed stone on a compacted sub-base." Its top must be "hard, smooth, level" and kept "as level as possible."

For turf, swap the BSA's 2 inch clay layer for a thin fine top. Our base preparation guide uses 1/4 to 1/2 inch of decomposed granite or rock dust for this, and rock dust is the finer choice it gives for putting greens.

Flat, not crowned, not sloped. A lawn base slopes 1 to 2 percent so water runs off. On a 12 ft wide court, 1.5 percent is about 2 1/8 inches of fall from board to board, and every slow ball would drift to the low side. Along a 60 ft court, 1 percent is 7.2 inches, so one end plays downhill. A crown (a raised center) pushes balls toward both boards. Build the court level both ways. Our base guide holds putting greens to about 1/8 inch under a 10 ft straightedge, and a bocce court needs the same.

Water goes down, not across. A flat court cannot shed water off its surface, so it has to drain through the turf, then the stone, then out. The BSA says "drain holes must be provided to prevent standing water." Greatmats suggests weep holes about 1/4 inch across, roughly every 8 ft around the perimeter. It also suggests PVC pipe under the court, laid like a French drain. Our view is to drill the weep holes low in the boards, at the top of the stone where the water collects, and to add the pipe on clay soil. Read how artificial turf drains for how water moves through the layers.

How high should the boards be, and what holds them?

The BSA says sideboards and backboards "must extend 6 to 12 inches above the playing surface." They are "rigid treated lumber, minimum of 2 inches thick," and must be backed by concrete or by 4x4 posts no more than 4 ft apart. A ball that hits a sideboard at more than 30 degrees should "consistently bank off." If the boards flex, add support or a hard plastic or rubber bumper so they bank true. Greatmats asks for curbing at least 6 inches high, fixed to the ground or base so it does not shift, and calls poured concrete the most durable and wood the easiest to build yourself.

One catch on the lumber: a nominal 2x board is 1 1/2 inches thick, and the BSA text does not say if it means nominal size, so check with your club if you want a sanctioned court.

The turf meets the boards like any hard edge: trim it tight to the board and nail it to a treated nailer board set in the base along the inside of the boards. A gap there leaves a groove along the rail.

The base material calculator runs the tonnage for your own court size, and the roll layout calculator checks the turf.

In what order do you build a turf bocce court?

1. Pick the size and lines. Choose USBF or BSA foul lines before anything is built.
2. Call 811, mark and dig. Dig the court plus the board and post line, then compact the sub-base.
3. Set posts and boards. Set 4x4 posts at 4 ft or less, or pour a concrete curb, and hang the boards level along a string line.
4. Drill the drain holes. Make them about every 8 ft, low on the boards, and lay pipe now if the soil is clay.
5. Build the base in lifts. Spread the stone in layers no thicker than about 2 inches and compact each one. Then add the fine top and screed it level both ways.
6. Check it flat. Lay a 10 ft straightedge in every direction and fill any gap over about 1/8 inch.
7. Lay and fasten the turf. Roll it down the court's length and fasten it at the boards. Our installation guide covers cutting and nailing.
8. Paint the lines. Mark the foul lines and center line on the boards and the surface.

Spec summary for a turf bocce court

When does this answer stop applying?

This page covers outdoor courts at grade. A tournament host should follow its own sanctioning body, since the USBF and BSA disagree on foul lines. Indoor and portable courts sit on a slab or a floor with no stone base, and the BSA says standards for those may still need work. A court on a roof or deck adds load limits; see rooftops and balconies. In frost country, a deeper base may be needed, as covered in turf in cold climates. The turf maker's install sheet outranks the general figures here.

Frequently asked questions

What is the smallest bocce court worth building?

The USBF says unofficial courts "can be smaller," and gives no minimum. The Bocce Standards Association says US courts are found from 60 to 100 ft long. Under USBF rules, the pallino must stop between the center line and the far foul line. On a 60 ft court with lines 13 ft from each end, that target zone is 30 - 13 = 17 ft long, and on a 40 ft court it shrinks to 7 ft. A short lane still works for kids, with closer foul lines.

Can I use leftover lawn turf for a bocce court?

You can, but it plays slow and uneven. Lawn turf usually has over an inch of pile, and the fibers grab the ball. Greatmats notes that taller pile gives less bounce and absorbs more energy, and a ball that dies early in thick fibers is hard to point close. Short, dense turf in the 3/8 to 3/4 inch range rolls truer.

Do I need a shock pad under a bocce court?

None of the three sources calls for one. A shock pad is a thick cushion layer used to soften falls on play areas and sports fields. A bocce court wants a firm surface, and Greatmats ties softer, energy-absorbing turf to less bounce. A padded turf with a thin 5 mm foam backing is a different thing, and Greatmats lists that type as its most popular for bocce.

How do I stop water pooling against the boards?

Give the water a way out at the bottom. The boards form a box, so water that drains through the turf collects in the stone at the edges. Drill weep holes about 1/4 inch across roughly every 8 ft, low in the boards, and on slow-draining clay, lay perforated pipe under the court to carry water away. Do not slope the court to fix it.

Can I play bocce on my existing turf lawn without boards?

Yes, as a casual lawn game, but it is not a court. A lawn slopes for drainage, so balls drift, and with no sideboards there are no bank shots. If you want a real court, cut out a strip, rebuild the base flat and add boards rather than trying to level the whole lawn.
