Measuring the Arc of a Basketball Shot

how to measure arc basketball

Measuring the trajectory or arc of a basketball shot is crucial for players who want to optimize their shooting technique. A shot with the proper arc can significantly improve the chances of the ball going through the hoop. To measure the arc accurately, you can use various methods and tools. Below we discuss tools available and techniques for effectively measuring the arc.

Measurement Tools

For measuring the arc of a basketball shot, there are several tools you might consider:

  • Laser Rangefinder: An advanced tool that provides precise measurements from one point to another, often used in surveying and construction.
  • Protractor App: An application on smartphones or tablets that uses the device’s sensors to measure angles relative to the Earth’s gravity.
  • Measuring Tape: A retractable tape measure used to determine the distance between two points manually.

Techniques for Measuring Arc

Laser Rangefinder 

To use a laser rangefinder for precision arc measurement:

  1. Determine the shooting position and the location of the hoop.
  2. Stand at the release point of the shot and point the rangefinder first to the hoop to measure the straight-line distance.
  3. Next, aim the rangefinder at the peak of the ball’s arc during a shot to measure the height.

Protractor App

With a protractor app, follow these steps:

  1. Secure the phone or tablet so that it has a side-on view of the player taking the shot.
  2. Record multiple shots using the app to gauge the angle of release each time.
  3. After recording several tries, calculate the average angle to ascertain the player’s typical arc.

Measuring Tape Method

If you prefer a measuring tape:

  1. Measure the distance from the release point of the shot to the hoop. This gives you the length of the arc.
  2. While observing multiple shots, visually estimate the apex height of the arc.
  3. Note down these measurements to better understand the arc’s properties.

Best Method for Accuracy

While all the above methods provide varying levels of accuracy, the Laser Rangefinder is generally the most accurate tool for measuring the precise distance to the hoop and the apex of the basketball’s arc. It minimizes human error and provides consistent results.

To achieve the best results, consider the player’s stance, the ball’s release point, and environmental factors that might affect the shot, such as wind or angle. Regular measurement and practice can help perfect the arc for a more consistent shooting performance.

Remember, practice combined with precise measurement can aid in developing an optimal shooting arc, leading to better-shooting percentages on the court. So, whether you’re a beginner or a seasoned player looking to improve your shot, don’t underestimate the importance of measuring and perfecting the arc of your basketball shots. Keep practicing and experimenting with different techniques until you find one that works best for you. With dedication and practice, you can master the perfect arc for your basketball shots. 


What is the ideal arc angle for a basketball shot?

The optimal arc angle for a basketball shot varies among players. Still, generally, an angle between 45 to 55 degrees is considered ideal for maximizing the chances of the ball going through the hoop.

Can using these measurement tools improve my shooting accuracy?

Absolutely. By using measurement tools to understand and refine the arc of your shots, you can adjust your technique to achieve a more consistent and effective shooting performance.

How often should I measure the arc of my shots?

Regular measurement can provide valuable feedback for adjusting and improving your shot. Consider measuring your shot arc during practice sessions at least once a week or whenever you’re making adjustments to your shooting technique.

Do environmental factors like wind affect the basketball’s arc?

Yes, environmental factors such as wind can significantly impact the trajectory of a basketball shot. It’s essential to account for these variables during practice and adjust your shooting technique accordingly.

Is it necessary to use high-tech tools for measuring the arc, or can I get by with more basic methods?

While high-tech tools like laser rangefinders provide more precision, you can still gain valuable insights with more basic methods like a protractor app or measuring tape. The key is consistency and using the method that works best for you.


Measuring the arc of a basketball shot is crucial for players looking to improve their shooting technique and accuracy. With various tools available, such as laser rangefinders, protractor apps, and measuring tapes, you can accurately measure the arc of your shots. Regular measurement and practice are crucial to perfecting the optimal shooting arc that works best for each player. So, keep practicing and experimenting until you find the perfect arc for your basketball shots. Happy shooting! However, it’s also important to remember that while measuring and perfecting the arc of a shot is essential, there are other factors at play as well, such as proper form, strength, and muscle memory. It’s vital to continually work on all aspects of your shooting technique to become well-rounded and successful.
