Short answer: a regulation backboard, as used in the NBA, is 72 inches wide by 42 inches tall (6 ft x 3.5 ft); FIBA’s is almost the same at 1,800 x 1,050 mm. Home hoops come smaller: 44 to 48 inches for kids and casual shooting, 50 to 54 inches for most driveways, and 60 to 72 inches if you want something close to a gym. Size matters less than material: a 54-inch tempered glass board plays better than a 60-inch plastic one.
Backboard sizes at a glance
| Width | Typical use | Usual mount | Example |
|---|---|---|---|
| 72 in (regulation) | Gyms, arenas, serious home courts | In-ground, wall-mounted | Goalrilla FT72 |
| 60 in | Large driveways, players who want a near-gym feel | In-ground | Silverback SB60 |
| 54 in | Most family driveways; the sweet spot | In-ground or portable | Silverback NXT 54 portable |
| 50 to 52 in | Smaller driveways, budget in-ground or portable | Portable or in-ground | Lifetime 52″ Power Lift |
| 44 to 48 in | Kids, shooting practice, tight spaces | Portable | Lifetime 44″ Impact portable |
Official backboard dimensions
| Spec | NBA | FIBA |
|---|---|---|
| Backboard | 72 x 42 in (6 x 3.5 ft) | 1,800 x 1,050 mm (70.9 x 41.3 in) |
| Material | Flat, transparent front surface | Laminated safety glass or tempered glass (top level) |
| Inner rectangle (target box) | 24 x 18 in, 2-in white lines | 590 x 450 mm (23.2 x 17.7 in) |
| Rim height | 10 ft to the top of the rim | 3,050 mm (10 ft) |
| Rim diameter | 18 in inside | 450 to 459 mm inside |
| Rim distance from board | 6 in to the nearest inside edge | 151 mm (5.9 in) |
Every home hoop, whatever the board size, uses the same 18-inch rim at a 10-foot height for adults, so you are practicing at the real target. A smaller board mostly changes bank shots and how much room there is for rebounds.
Backboard materials compared
| Material | Rebound | Durability | Found on | Price level |
|---|---|---|---|---|
| Tempered glass | Best: closest to a gym board | Strong but heavy; tempered glass can still break under extreme impact | Premium in-ground and a few premium portables | $$$$ |
| Acrylic | Good; clear like glass | Lighter than glass; scratches and can yellow in the sun over the years | Mid-price in-ground and portable hoops | $$ to $$$ |
| Polycarbonate | Fair; duller rebound | Virtually unbreakable; common on driveway hoops | Most portables and budget in-ground hoops | $ to $$ |
| Molded plastic (HDPE, “Impact”) | Low | Tough and cheap | Kids’ and budget portables | $ |
Which backboard size should you buy?
- Mostly kids under 12, or shooting around: 44 to 48 inches. A cheaper portable like the Lifetime 44″ Impact is enough.
- A family driveway with teens and adults: 54 inches. It is wide enough for real bank shots and still fits a normal driveway. Glass or acrylic if your budget allows, polycarbonate if not.
- Serious players, or a dedicated half court: 60 to 72 inches with tempered glass, on an in-ground pole. That is where the Silverback SB60 and Goalrilla FT72 sit.
- Check your space: a 72-inch board needs an in-ground system with a long overhang and a driveway wide enough to play under it. Measure before you buy.

FAQ
What size is an NBA backboard?
72 inches wide by 42 inches tall (6 x 3.5 feet), with a 24 x 18 inch rectangle above the rim.
What is the best backboard size for a home hoop?
54 inches for most families. Go smaller (44 to 48) for young kids or tight spaces, and larger (60 to 72) only if you have the room and want a gym-like setup.
Is a glass backboard worth it?
If you play a lot, yes: tempered glass gives the truest rebound. It also makes the hoop heavier and pricier, and on a portable hoop it makes the system top-heavy, so most glass boards are on in-ground hoops.
Acrylic or polycarbonate?
Acrylic rebounds better and looks like glass; polycarbonate is nearly unbreakable but plays duller. For kids who will hang on everything, polycarbonate is the safer choice.
How high should a basketball hoop be?
10 feet from the floor to the top of the rim for adults and teens (NBA and FIBA). Adjustable home hoops usually go from 7.5 to 10 feet for younger players.
