Question: What is the 10% rule for choosing a bowling ball weight?

A: The 10% rule suggests picking a ball that weighs approximately 10% of your body weight, with 16 lbs being the maximum. For instance, a 180 lb person would aim for around 15–16 lbs, while a 120 lb person might start at 12 lbs. This is only a starting guideline — always test the weight by swinging and throwing it. Comfort, control, and injury prevention are more important than strictly following the percentage.
