18 inches tall Backboards are 6 feet (183 cm) broad by 3.5 feet (107 cm) tall in standard sizes. The diameter of all basketball rims (hoops) is 18 inches (46 cm). Standard ball sizes are 7 inches (17 cm) in diameter for play on school playgrounds and courts, 10 inches (25 cm) for play on **neighborhood streets**, and 11 inches (28 cm) for play on outdoor courts.

The size of your basket does not affect how hard it is to shoot balls through it. The only way to make your basket harder or easier to shoot through is by changing the circumference of its rim. A larger circle means more space between the ball and the backboard, so it's harder to shoot through. A smaller circle means less space, so it's easier to shoot through.

Here are some examples of different-sized baskets:

A 9-inch basket has a perimeter of **about 63 inches**. It's suitable for **younger children** or for use on a driveway or other court that is not regularly maintained by a landscaper.

A 12-inch basket has a perimeter of **about 75 inches**. It's useful for **older children** or for use on a court that is regularly maintained by a landscaper.

The hoop's peak is 10 feet (305 cm) above the ground. Backboards are 72 inches (183 cm) broad by 42 inches (110 cm) tall in standard sizes. The backboard's inner rectangle measures 24 inches (61 cm) wide by 18 inches (46 cm) tall. The center of the backboard is 1 inch (2.5 cm) from the edge.

There are 12 inches (30 cm) between the top of the backboard and the bottom of the pole. The pole is 14 inches (35 cm) in diameter. The distance from the center of **one side** of the base to the opposite side is 32 inches (81 cm).

The area above the hoop is called the backboard. It performs two functions: it gives the ball better visibility, and it prevents players from being injured by falling balls. The backboard is made of glass or plastic. It can be as small as 4 by **6 inches** (10 by 15 cm), but most shops that sell basketballs will have a selection of size options for you to choose from. The larger the backboard, the more it increases the ball's surface area, which means **more space** for **air bubbles** underneath the surface of the ball when it's shot. This reduces the risk of injury due to collision with the backboard.

The height of the backboard depends on the level of play in your area.

Backboards are 6 feet (183 cm) broad by **3.5 feet** (107 cm) tall in standard sizes.

The height of **a basketball ring** above the floor varies depending on how high you can put it up. The higher the ring, the farther back you have to stand from the basket to shoot the ball. This is called "Hoop Height". The distance between the top of the ring and the bottom of the ring is called the "Hoop Radius".

There are three main types of **basketball hoops**: horizontal, vertical, and hybrid.

A horizontal hoop is set directly into the middle of the playing surface. It is usually made of metal or plastic and is used for recreational play. Some public venues use this type of hoop for **basketball games**.

A vertical hoop is mounted on a pole or structure and is used for competition. It may be made of metal or fiberglass and comes in **two shapes**: inline and off-center.

An inline vertical hoop is same height as the playing surface. It looks like a miniature version of a half-court hoop. Inline hoops are used by youth leagues and street teams because they require less space than off-center hoops.

The rim is exactly 10 feet from the ground for **junior high, high school**, NCAA, WNBA, NBA, and FIBA. Rims are 18 inches in diameter at **all levels** of play. At each of these levels, the backboards are likewise the same size. A standard backboard is 6 feet broad and 42 inches (3.5 feet) tall. Some backboards are made of glass but most are made of plastic.

The floor is supposed to be flat, but there are always bumps and dips in it. The height of these irregularities varies by sport and venue. In basketball, the average height of a basketball court is 10 feet 6 inches; in tennis, it's usually around 12 feet; and in ice hockey, it can be as much as 20 feet.

The difference between the highest point on the floor and the lowest point should be about 2 inches. If it's less than that, you're playing on an uneven surface or there is something wrong with your court. If it's more than that, try to get someone to smooth out the floor before you play your next game. You should never have to worry about damage to the floor while it's wet!

Courts are also graded based on how hard they are. If you know **any kids** who play basketball, they probably have an opinion on which courts are the hardest and which are the softest.

One can also wonder how tall the NBA rims are. They usually range from 7 feet 6 inches to 8 feet across.

Basketballs are softballs with **rubber balls** attached to a string with a ball at the other end. The balls are spherical but not perfectly so; they have some irregularity in their shape that allows them to bounce erratically, which is what gives them **their erratic flight path** when thrown. A well-made basketball will reach a height of **about 10 feet** (3 m) before dropping down to the floor.

The size of the basket determines how high one can shoot the ball. The higher the hoop, the farther it can be shot. Modern basketballs are inflated so that they will fly further. On average, a player shoots the ball around half way up the height of the backboard.

There are two types of shots in basketball: jumpers and layups. In both cases, the goal is to put the ball through the basket. However, for a jumper to be valid, you need to leave **at least half** of the ball visible over the edge of the basket.
