So it can be said that the universally accepted diameter of basketball rim is 18 inches or 45 cm with 9 inches radius.
What Is The Length Of The Net and why it connected with the Rim?
Basically, the net is attached to the rim to ensure visual recognition of a basket. The net makes it easy to confirm if the ball has passed through the rim at first appearance. The net is free at the bottom and allows the ball to fall down.
There’s an interesting story about the netting of the basketball rim. When Dr. James Naismith invented the basketball game in 1891, he used a peach basket as a rim. There’s a problem with the peach basket that every time an athlete score, a man had to climb to retrieve the ball. After almost a decade later, the peach basket was replaced by a metal rim and netting.
The first time the net was closed at the bottom. So, just like a peach basket, a man had to climb the hoop to retrieve the ball. Later in almost 1906, the net was cut off from the bottom to let the ball fall down.
According to the NBA rulebook, the net of the rim should be hanged between 15 to 18 inches from the rim. NBA also states that the thread count of the net has to be more than 30 and less than 120 of the total threads.
The Purpose And Dimension Of The White Rectangle Above The Rim
You may have noticed in every professional competition there’s a rectangle in the backboard just above the rim. If you know the NBA has a section about this rectangle on their rulebook.
Let’s see the importance, purpose, and dimension of this rectangle.
Dimension: The National Basketball Association clearly stated that there must be a 2-inch white rectangle mark on the transparent backboard centered just behind the rim. The rectangle should be 24 inches wide and 18 inches in height. The base of the rectangle must be started from the rim.
Intention: when the player runs with the ball, it is quite difficult for them to target the rim and throw the ball while in speedy movement. On the other hand, backboards on the competitive game have to be transparent. So, the transparency of the backboard may affect the target accuracy of the players. This rectangle works as a visual target for them when they try to shoot the ball. This rectangle helps players to set targets from a distance when they are running.
Types Of Basketball Rim
There are basically three types of basketball rim available on the market.
Standard Rim: Standard rim is directly attached to the backboard and has no spring on it. Because of not having springs, it can easily damage the backboard. It can also be the reason for the injury of a player. When a player goes for a dunk, the standard rim does not bend down. So, it increases the chances of breaking the blackboard.
Exposed Spring Breakaway Rim: The breakaway rim is a kind of rim that has a hinge and a spring where it is attached to the backboard. Nowadays, almost the entire basketball hoop has these types of rims. The breakaway rim allows players to dunk without the risk of shattering the backboard and get injured.
But because of being exposed, it has the chance of getting rusted. If the spring somehow gets touched in wet weather, it increases the chance of having rust.
Enclosed Spring Breakaway Rim: These types of the rim have the spring covered. So it hardly gets touched with wet weather. That’s why it ensures the best long-lasting service. These types of the rim are seen in top and high-level hoops. The enclosed breakaway rim offers safety, pro, and long-lasting playing.
The NBA, The FIBA, The NCAA, all professional leagues used enclosed breakaway rims.
