A ten-pin bowling ball weighs between 6 and 16 pounds. Sixteen pounds is the maximum the United States Bowling Congress (USBC) allows in certified play. Most adult bowlers use a 12- to 15-pound ball, and many competitive bowlers settle on 14 or 15 pounds rather than the full 16.
The right weight for you depends on your strength and how many games you bowl in a session. A ball you can control for an entire set of games beats a heavier one you can only throw well for a frame or two. For shipping, a single boxed bowling ball typically comes to about 15 to 20 pounds.
What Is the Standard Weight Range for Bowling Balls?
Ten-pin balls are sold in 1-pound steps from 6 to 16 pounds. All of them are close to the same size. USBC requires a diameter between 8.500 and 8.595 inches, so a heavier ball is denser inside, not bigger. That’s why a 10-pound and a 16-pound ball look almost identical on the rack.
| Bowler | Typical ball weight | Why |
|---|---|---|
| Young children (about 6–9) | 6–8 lb | Light enough to swing without straining the arm |
| Older children and young teens | 8–11 lb | Builds proper form before adding weight |
| Recreational adults | 10–14 lb | Comfortable for a few games of casual bowling |
| Regular league bowlers | 13–15 lb | Balances pin carry with control over a full series |
| Competitive and professional bowlers | 14–16 lb | More momentum through the pins, with practiced technique |
Bowling-center house balls usually run from about 6 to 16 pounds, marked with the weight on the ball. They’re drilled with generic finger holes, so many bowlers find a house ball feels heavier than a fitted ball of the same weight.
How Much Do Bowling Balls Weigh in Other Bowling Games?
Smaller bowling games use much lighter balls without finger holes, small enough to hold in the palm.
| Game | Typical maximum weight | Approximate diameter | Finger holes |
|---|---|---|---|
| Ten-pin | 16 lb | 8.5–8.595 in | Yes |
| Five-pin (Canada) | About 3.5 lb | About 5 in | No |
| Duckpin | About 3.75 lb | About 4.75–5 in | No |
| Candlepin | About 2.4 lb | About 4.5 in | No |
How Do You Choose the Right Bowling Ball Weight?
A common starting point is about 10% of your body weight, up to the 16-pound maximum. A 140-pound adult would start around 14 pounds, for example. Treat that as a first guess, then adjust for how the ball feels.
- Hold test: hold the ball in your stance position for 20 to 30 seconds. If your arm shakes or your wrist bends back, go down a pound.
- Swing test: you should be able to swing the ball smoothly without muscling it or dropping your shoulder.
- Session test: if your accuracy or ball speed falls apart by the third game, the ball is too heavy for regular use.
- Fit matters: a ball drilled for your hand feels lighter than a house ball of the same weight, so many bowlers move up a pound once they have a fitted ball.
Heavier isn’t automatically better. A heavier ball deflects less when it hits the pins, but only if you can throw it at a consistent speed and on target. Many experienced bowlers choose 14 or 15 pounds for that reason.
Does Drilling Change How Much a Bowling Ball Weighs?
Yes, slightly. Drilling the finger and thumb holes removes a few ounces of material, and the exact amount depends on the hole sizes and depths. Pro shops account for this when they drill, so the finished ball stays at the weight you asked for. The layout of the holes changes how the ball rolls far more than the small loss of weight does.
USBC rules have also changed in recent years. Since August 1, 2020, balance holes (extra holes once drilled to adjust a ball’s static weight) aren’t allowed in USBC-certified competition. If you bought an older ball with a balance hole, a pro shop can plug it so the ball is legal again.
How Do You Weigh a Bowling Ball at Home?
The simplest method uses a bathroom scale. Weigh yourself, then weigh yourself holding the ball, and subtract the first number from the second. A digital luggage scale with a ball bag, or a kitchen or shipping scale that goes up to 20 pounds, is more precise. Our guide to how to weigh packages at home compares these methods.
Most bowling balls also have the weight printed or engraved near the logo or serial number. If you’re selling or shipping a ball, weigh it in its box so the label matches what the carrier measures. The difference between the ball alone and the sealed package is explained in our guide to gross weight vs net weight.
How Much Does a Bowling Ball Weigh When Packed for Shipping?
A boxed 15-pound ball usually weighs about 17 to 20 pounds once you add a bag, padding and a sturdy box. Bowling balls are dense, so dimensional weight rarely matters for them. A 12 × 12 × 12 inch box, which leaves about 2 inches of padding around the ball, measures 1,728 cubic inches. That works out to a UPS dimensional weight of 13 pounds (1,728 ÷ 139, rounded up), less than the packed ball weighs. The box is also not over the 1-cubic-foot point where USPS dimensional pricing starts. In practice, you pay for what the box weighs on the scale.
| Package | Typical packed weight | What to know |
|---|---|---|
| One ball | About 15–20 lb | Fits USPS and UPS ground services easily |
| Two balls in one box | About 30–36 lb | Use a divider and extra padding between them |
| Three balls in one box | About 45–52 lb | Over 50 lb, UPS adds an Additional Handling charge, so consider two boxes |
| Any box | Up to 70 lb (USPS) or 150 lb (UPS) | Carrier maximum weight limits |
To pack a bowling ball:
- Clean the ball and put it in a plastic bag to protect the coverstock.
- Wrap it in several layers of bubble wrap or foam.
- Place it in a double-wall box with about 2 inches of padding on every side, or in a bowling ball box with a foam insert.
- Fill any empty space so the ball can’t roll. A loose bowling ball can break through the side of a box.
- Tape all seams and mark the box “Heavy.”

Frequently Asked Questions
What is the heaviest bowling ball allowed?
The heaviest bowling ball allowed in USBC-certified ten-pin play is 16 pounds. There’s no lower limit for certified play, which is why balls are sold from 6 pounds up. Every legal ball also has to measure between 8.500 and 8.595 inches across, so heavier balls are denser, not larger.
What weight bowling ball should a beginner use?
Most adult beginners do well with a 10- to 14-pound bowling ball, using about 10% of body weight as a starting point. Hold the ball in your stance for 20 to 30 seconds and take a few practice swings. If your arm shakes or your form breaks down, drop a pound until it feels controlled.
How much does a bowling ball weigh in kilograms?
Ten-pin bowling balls weigh about 2.7 to 7.3 kilograms, since 6 pounds is roughly 2.7 kg and the 16-pound maximum is about 7.26 kg. A common 14-pound ball weighs about 6.35 kg, and a 12-pound ball about 5.4 kg. Divide the weight in pounds by 2.205 to convert any ball.
How much does it weigh to ship a bowling ball?
A single 15-pound bowling ball packed in a bag, padding and a sturdy box usually weighs about 17 to 20 pounds. Because the ball is so dense, carriers bill that actual weight, not a dimensional weight, in a snug box. Two balls in one box come to roughly 30 to 36 pounds.
