The short answer
A regulation basketball hoop is 10 feet (3.05 m) from the floor to the top of the rim, in the NBA, college and high school. The USA Basketball and NBA youth guidelines recommend 8 feet for ages 7 to 8 and 9 feet for ages 9 to 11, moving to 10 feet from age 12.
The standard rim height is the same at almost every level of play in the US. What changes is how high younger players should shoot at, and how you set a hoop up so it is genuinely at the height you think it is.
Regulation hoop height
The NBA rules set the rim 10 feet (3.05 m) above the floor. The same height is used in the WNBA, NCAA college basketball, high school basketball under NFHS rules, and FIBA international play. The measurement is from the playing surface to the top edge of the rim, not to the bottom of the backboard or the net.
Other parts of a regulation goal, from the NBA rules:
- Rim: 18 inches (45.7 cm) across the inside.
- Backboard: 6 feet wide by 3.5 feet tall (1.83 by 1.07 m).
- Free-throw line: 15 feet (4.57 m) from the face of the backboard.
Recommended heights by age
USA Basketball and the NBA publish youth guidelines that lower the rim, shorten the court and use a smaller ball for younger players. The idea is that kids learn proper shooting form when the target is in reach, rather than heaving the ball with two hands.
| Age | Rim height | Ball size | Free-throw distance |
|---|---|---|---|
| 7 to 8 | 8 ft (2.44 m) | Size 5, 27.5 in | 14 ft (4.27 m) |
| 9 to 11 | 9 ft (2.74 m) | Size 6, 28.5 in | 14 ft (4.27 m) |
| 12 to 14 | 10 ft (3.05 m) | Girls size 6, boys size 7 (29.5 in) | 15 ft (4.57 m) |
| Grades 9 to 12 | 10 ft (3.05 m) | Girls size 6, boys size 7 | 15 ft (4.57 m) |
These are guidelines, not rules. Your local league will set its own heights, so check what your child plays on before you set a home hoop.
Choosing a hoop for a home court
Adjustable or fixed
If you have children under 12, an adjustable hoop lets you lower it now and raise it as they grow. Adjustable systems move up and down in steps with a crank or handle; check the lowest setting before you buy, since ranges differ between models. A fixed hoop is simpler and often stiffer, but stays at one height.
In-ground, wall-mounted or portable
- In-ground: a steel pole set in a concrete footing. It is the most stable and the usual choice for a built court.
- Wall or roof mounted: fixed to a garage or a gym wall. Check the structure can take the load and the force of a dunk.
- Portable: a weighted base filled with water or sand. Cheaper and movable, but it wobbles more and can tip if someone hangs on the rim.
What hoops cost
HomeAdvisor (updated June 2026) puts in-ground hoops at $400 to $1,600, with professional installation about $450, and acrylic-backboard models at $1,800 to $4,400. A Texas court builder, Sport Court of Austin, quotes $1,500 to $3,500 for the adjustable hoops it installs on new courts. These are guides, not quotes.
How to measure hoop height
- Measure from the playing surface directly below the rim, not from nearby grass or a sloped driveway.
- Hook a tape measure over the front of the rim and read where it meets the surface.
- On an adjustable hoop, check the height at each setting against the marker, since markers are often a little out.
- Check that the rim is level side to side, and that the backboard face is vertical.
If the court slopes for drainage, measure from the point directly below the rim. Court builders keep the slope to about 1 inch in 10 feet, so the difference across a home court is small, but driveway hoops can be noticeably off.
Where to put the hoop
On a regulation court the face of the backboard is 4 feet (1.22 m) inside the baseline, so the pole stands behind the baseline and the rim overhangs the court. At home, the same applies: the pole should be behind the playing area, padded, and set far enough back that players driving to the basket do not run into it. For an in-ground hoop the footing is usually poured at the same time as the court slab, which is one reason to plan the hoop before the concrete goes in.
Our backyard court guide covers where a hoop fits on a typical home court, and the half court page shows how the hoop position sets the lane and the three-point arc.
Indoor ceilings and hoop height
Indoors, the rim at 10 feet is only the start. A shot arcs well above the rim, so a low ceiling stops normal shooting even when the hoop itself fits. If you are planning a court in a barn, basement or garage, check the clear height with a builder before you buy a hoop. Our indoor court page covers what to check.
Planning the whole court
A hoop is one line on the budget. The slab, surface, lighting and fencing make up most of the cost of a court. The basketball court cost calculator gives a typical range for the size and surface you want, with a hoop and other extras added, so you know roughly what to expect before you ask for quotes.
