This bowling ball weight calculator is designed to help bowlers determine the ideal weight of their bowling ball using Ball Weight = (Body Weight / 11) + 1 formula.
Let’s say we have a bowler named John who weighs 180 pounds and has been bowling for 2 years. The calculator might suggest a ball weight of 15 pounds based on these inputs.

- Ten-Pin Bowling Balls: are the most common type used in standard bowling alleys. They range from 6 to 16 pounds, with heavier weights preferred by more experienced bowlers. The diameter is typically between 8.500 and 8.595 inches.
- Duckpin and Candlepin Balls: balls are smaller and lighter, designed for specific variations of bowling. Duckpin balls are used in a game that features smaller pins, while candlepin balls are even lighter and are used in a unique bowling format popular in New England.
- Youth and Children’s Balls: balls are specifically designed for younger bowlers, typically ranging from 6 to 12 pounds. The general guideline is to match the ball weight to the child’s age, such as a 6-pound ball for a 6-year-old.
- Senior and Professional Balls: Senior bowlers often use balls ranging from 10 to 14 pounds, while professional bowlers typically use balls weighing between 14 to 16 pounds, depending on their strength and skill level.
- Specialized Balls: Plastic balls are often used for spares due to their straight trajectory, while reactive resin and urethane balls are favored by advanced bowlers for their ability to hook and provide better pin action.
Bowling Ball Weight Formula
The basic formula for calculating bowling ball weight is:
Ball Weight = (Body Weight / 11) + 1This formula provides a starting point, but it’s important to consider other factors as well.
For a person weighing 165 pounds:
Ball Weight = (165 / 11) + 1 ≈ 16 pounds
For a person weighing 132 pounds:
Ball Weight = (132 / 11) + 1 ≈ 13 pounds
How Heavy Should My Bowling Ball Be?
- Body Weight: Generally, your ball should weigh about 10% of your body weight, plus 1 pound.
- Strength: Consider your upper body strength and ability to control the ball.
- Experience: Beginners might start with lighter balls and progress to heavier ones as they improve.
- Comfort: The ball should feel comfortable when you hold it and swing it.
- Bowling Style: Different styles may benefit from slightly different weights.
How Do I Know What Weight Bowling Ball to Use?
Try Different Weights: Start by testing balls of various weights at your local bowling alley.
Assess Your Control: You should be able to comfortably hold and swing the ball without straining.
Consider Your Throwing Speed: Faster throws might benefit from slightly heavier balls.
Evaluate Your Accuracy: If you’re struggling to hit your target, the ball might be too heavy or too light.
Consult a Pro: A professional bowler or coach can provide personalized advice based on your technique and physique.
What is a Better Estimate for the Weight of a Bowling Ball?
- Gender: Women might prefer slightly lighter balls than men of the same weight.
- Age: Younger bowlers and seniors might benefit from lighter balls.
- Fitness Level: More physically fit individuals might handle heavier balls more easily.
- Bowling Frequency: Regular bowlers may prefer heavier balls as they develop strength and technique.
A refined estimate might use a range rather than a single number, giving bowlers some flexibility to find their perfect fit.
What is the Rule of Thumb for Bowling Ball Weight?

Choose a ball that weighs approximately 10% of your body weight, plus 1 pound.
Is a 14 lb Bowling Ball Too Heavy?
A 14-pound bowling ball is not inherently too heavy, but whether it’s appropriate depends on the individual bowler. Here’s when a 14 lb ball might be suitable:
- For men weighing between 140-160 pounds
- For women weighing between 150-170 pounds
