This option is best for recreational bowlers who are getting their first bowling ball or have not had a ball professionally fit for them. Having a ball drilled at your local pro shop can cost as much as $50 or more. Our standard drilling options come in five basic sizes in both right and left hand. (X-Small, Small, Medium, Large, X-Large)
Below are five examples of typical hole sizes you will find in house balls at the local bowling alley.
House ball fitting examples.
Need help choosing a size? No problem!
Example: You like the 8 lb ball but the holes are too small. The 12 lb ball fits good but it's too heavy. The answer would be to purchase an 8 lb ball with Medium Standard Drilling. It's that simple!
*The suggestions above do not guarantee a perfect fit. It is just a simplified way of getting you a good fitting ball that you can go out have some fun with.
