Backyard Basketball Court Guide: Sizes, Surfaces & Ideas
Updated
A backyard basketball court is more than a hoop over a slab. Most home courts on the Gulf Coast do more than one job. Picture a hoop and key at one end, pickleball lines down the middle, and a net for volleyball or badminton.
This guide covers sizes, hoops, surfaces, and ideas, so you can plan one slab for every game your family plays. To see how these courts come together, visit our page on backyard courts.
Common backyard basketball court sizes
There's no rulebook size for a home court. Pick a size based on the games you want to play and the space you have.
| Size | Square feet | Good for |
|---|---|---|
| 20 × 20 ft | 400 | Shooting, free throws, one-on-one |
| 30 × 30 ft | 900 | Half-court games and 3-on-3 |
| 50 × 42 ft | 2,100 | A full high school half court |
The first two are home sizes, not rulebook sizes. The last is half of the high school court shown on the NFHS court diagram (opens in new tab). Square feet are simple math.
Start small with a shooting pad
A 20 × 20 ft pad fits the 12-ft-wide lane with 4 feet to spare on each side. The high school free-throw line sits 19 feet from the baseline, so a 20-ft-deep pad leaves just 1 foot behind it.
That works for shooting practice. It's tight for games.
Plan on 30 × 30 feet for half-court games
HomeGuide (opens in new tab) calls a 30 × 30 ft half court the typical backyard court. It says home courts should be at least that big to allow 3-on-3 games and 3-point shots.
Know what fits. The high school 3-point arc sits 19 ft 9 in from the center of the basket. On a 30-ft-wide pad, only the top of the arc fits. The sides run off the pad about 18 feet out from the baseline. (That's geometry from the NFHS layout.)
Go 50 × 42 feet for a regulation-style half court
The NFHS basketball rules (Rule 1, via Draper (opens in new tab)) list 84 × 50 ft as the ideal high school court (Rule 1-1). Half of that is 50 ft wide by 42 ft deep. It holds the full lane, the full arc, and the corners.
For every line and measurement, see our guide to half court basketball dimensions.
Choose the right hoop
The hoop is the one piece every basketball court needs. Choose it early, because an in-ground pole needs its own footing.
Pick in-ground, wall-mount, or portable
- In-ground: a steel pole set in a concrete footing. The sturdiest choice for a court. Many models adjust in height, so kids can play on a lower rim.
- Wall-mount: bolts to a garage or wall. It works when the court sits right against a building.
- Portable: a base you fill with water or sand. The easiest start, and it can move.
HomeGuide notes that portable hoops cost the least, while mounted and in-ground hoops are sturdier. It also suggests checking your HOA rules before you install a permanent mounted or in-ground hoop.
Set the backboard 4 feet in from the baseline
On a regulation court, the face of the backboard sits 4 feet inside the baseline (NFHS Rule 1-8-1). The rim is 10 feet high (Rule 1-11-1).
For an in-ground hoop, the overhang is the distance from the pole to the backboard face. That number decides where the pole goes. Subtract 4 feet from the overhang to find how far behind the baseline the pole sits:
- Overhang of 4 feet: the pole sits right on the baseline.
- Overhang over 4 feet: the pole sits behind the baseline, off the court.
- Overhang under 4 feet: the pole ends up on the court.
Check the overhang in the hoop's specs before the footing is poured.
Pad the pole and leave room around the court
NFHS rules call for at least 3 feet, and preferably 10 feet, of open space outside the lines (Rule 1-2-1). Players drive hard to the hoop. HomeGuide lists pole padding as an upgrade that protects players from injury.
Pick a surface
A court has two parts: the base under it and the surface you play on.
Choose coated concrete, tiles, or a bare slab
HomeGuide says asphalt and concrete are the most popular materials for outdoor play. It lists rubber tiles for indoor or outdoor courts. Your main choices:
- Concrete with an acrylic coating: a colored, textured surface with painted lines. The classic outdoor court.
- Modular court tiles: interlocking tiles laid over a concrete base. Several brands make them.
- Bare concrete or asphalt: the simplest start. You can add a coating later.
Our guides on Gulf Coast court surfaces and court tiles vs concrete compare them in detail.
Go lighter on color to beat the heat
HomeGuide (opens in new tab) notes that light colors absorb less heat, for a cooler court surface. On a Gulf Coast summer afternoon, a cooler court means longer games.
Add more games to the same slab
This is where a backyard court earns its space. HomeGuide notes that multi-use courts use lines painted in different colors for basketball, pickleball, and other sports. It says they typically run 1,200 to 2,400 square feet.
Add pickleball lines down the middle
A pickleball court is 20 × 44 feet. The USA Pickleball rulebook (opens in new tab) sets a 30 × 60 ft minimum playing surface (Rule 3.A.3).
One layout that works well: a 30 × 60 ft pad with pickleball lines centered and a hoop at one end. The basketball key overlaps the end of the pickleball court. Paint each sport's lines in its own color so players can tell them apart.
Share the net line with badminton or volleyball
The center of the pad can hold more than one net. Badminton and backyard volleyball can use the same net line as pickleball, with a taller net. Ask about net post sleeves set before the pour, so posts come out and leave a flat court.
Sizes for those games are in our backyard volleyball and badminton court guide.
Paint games for younger kids
Four square, hopscotch, and a painted target are just paint. Add the games your family plays. For full layouts, see our basketball and pickleball combo court guide.
Backyard basketball court ideas
Once the size and surface are set, the fun part starts.
Make it yours with color and a logo
Paint the key a second color, or add a family name or logo at center court. Angi (opens in new tab) lists custom logos among the extras that add to the price, so decide early.
Light it for evening games
Summer evenings are cooler for play. If you might want lights someday, ask about running conduit under the pad before it's poured. Adding it later means working around a finished court.
Stop chasing loose balls
HomeGuide lists rebounder nets to protect landscaping and cut down on chasing the ball. A fence along the far side does the same job for the whole court.
Add shade and a place to sit
HomeGuide lists bench seating and fabric shades, which block rain and UV rays. A bench in the shade gives players a spot to rest between games.
Try these small-yard ideas
- Driveway hoop: HomeGuide calls a portable hoop on your existing driveway the cheapest way to get a court.
- Shooting pad: a 20 × 20 ft pad holds the lane and free-throw line.
- One slab, many games: skip a separate pickleball court and share one pad.
Planning checklist
Settle these before anyone breaks ground.
Check space, slope, access, and approvals
- Space: Measure the flattest open area. Add runout around the lines, at least 3 feet and ideally more.
- Slope: Courts are built on a slight slope so rain runs off. HomeGuide suggests 0.83% to 1% in one direction. Across 30 feet, that's about 3 to 3.6 inches.
- Drainage: Angi notes that rainy areas need strong drainage systems. On the Gulf Coast, heavy downpours make this a must.
- Access: Angi says steep slopes and hard-to-reach backyards can raise labor and equipment costs. Check that trucks can reach the spot.
- Permits and HOA: HomeGuide says a permanent concrete, asphalt, or paver court typically needs a permit. Get any HOA approval in writing.
- Utilities: Call 811 before digging so buried lines get marked.
- Storms: Before a tropical storm, take down nets and secure or store a portable hoop.
Set a budget before you pick extras
HomeGuide lists $3,600 to $14,400 for a 30 × 30 ft half court, including a base, a painted surface, and one hoop. That's a national figure, not a quote. Your yard can land above or below it.
For full national ranges, read our basketball court cost guide. For a number for your own yard, ask about your court and send a few photos. The quote is free.

FAQ
What size should a backyard basketball court be?
HomeGuide calls 30 × 30 feet the typical backyard half court. A 20 × 20 ft pad works for shooting. A 50 × 42 ft court matches a high school half court.
Is a 30 × 30 court big enough for half court?
Yes, for pickup and 3-on-3 games, according to HomeGuide. It fits the full lane and free-throw line, but only the top of the high school 3-point arc.
What is the best surface for an outdoor basketball court?
It depends on your budget and how you play. HomeGuide says asphalt and concrete are the most popular outdoor materials. A colored acrylic coating or modular tiles go on top.
Can I add pickleball lines to a basketball court?
Yes. For a full pickleball court, plan a 30 × 60 ft surface, the USA Pickleball minimum. Use a different line color so each game is easy to read.
Does a backyard court need drainage?
Yes. Courts are built with a slight slope, about 0.83% to 1% per HomeGuide, so rain runs off. On the Gulf Coast, a court that puddles stays slick after every storm.
