How to Check a Golf Ball's Balance

Chasing consistency on the golf course often feels like a battle against a thousand tiny variables. But one you might be overlooking is sitting right in the palm of your hand: the golf ball itself. A perfectly struck putt can still drift offline, and a pure drive can develop an unexpected wobble if the ball is out of balance. This guide will walk you through exactly how to check your golf balls for balance, giving you a simple method to ensure your equipment isn't sabotaging your best swings.

Why a Balanced Golf Ball Matters More Than You Think

Modern golf balls are engineering marvels, but the manufacturing process is not flawless. Every ball is made of multiple layers, starting with a central core. If that core is perfectly centered, the ball will have a uniform weight distribution. However, if the core settles just a fraction of a millimeter off-center during production, the ball will have a “heavy side” and a “light side.”

You might think such a tiny imperfection wouldn't matter, but it does, thanks to physics.

• On the Greens: This is where an imbalanced ball does the most damage. A putt is ideally meant to roll end-over-end. If a ball has a heavy side, it will try to find its preferred axis and start to wobble as it slows down near the hole. You can strike a putt perfectly on your intended line, but if the ball wobbles, it can easily drift a cup-out and lip out. Taking this variable out of play is one of the easiest ways to improve your confidence over short putts.
• In the Air: While the effect is less pronounced on full shots, an unbalanced ball can affect aerodynamics. An off-center ball can impart a subtle, unwanted side spin, exaggerating a hook or slice, or leading to a less stable and predictable ball flight. You might hit two nearly identical swings and get two different results, leaving you scratching your head.

Think of it like a tire on your car. If a tire is out of balance, your car will start to shake at high speeds. The same principle applies to a golf ball. At high swing speeds and even on the slow roll of a putt, balance matters.

What You’ll Need: The Kitchen Counter Test

The good news is you don’t need a high-tech laboratory to check your golf balls. You can do this with a few common household items. The most popular method is the Epsom salt float test. The regular density of water isn’t enough to float a golf ball, but adding salt increases the water’s specific gravity, allowing the ball to become buoyant.

Here’s what you need to gather:

• A clear bowl or large glass: Something deep enough to allow the ball to be fully submerged without touching the bottom. A large pint glass or a small mixing bowl works perfectly.
• Epsom salts: You'll find these in the pharmacy or grocery store. Regular table salt works too, but you’ll need a lot more of it to get the right density.
• Warm water: The salt dissolves much more easily in warm water.
• A permanent marker: A fine-tipped Sharpie is ideal for marking the ball.

Step-by-Step Instructions: The Epsom Salt Float Test

Once you have your items, you’re ready to become your own quality control inspector. Follow these simple steps for each ball in a sleeve. It's a great activity to do while watching golf on a weekend afternoon.

Step 1: Create Your Saline Solution

Fill your bowl or glass about three-quarters full with warm water. Begin adding Epsom salts to the water a few tablespoons at a time, stirring until it dissolves completely. The goal is to make the water dense enough for a golf ball to float. Keep adding salt and stirring until a test ball floats with about a third of its surface above the water line. If it sinks, you need more salt. There's no perfect ratio, just add salt until it works.

Step 2: Let the Ball Settle

Gently place one of your golf balls into the solution. Let it bob and turn until it comes to a complete rest. The physical principle at work is simple: a sphere will always orient itself with its heaviest point facing directly down toward the earth's center of gravity. This means the lightest point of the golf ball will be at the very top, pointing towards the ceiling.

Step 3: Mark the "Light Pole"

Once the ball has stopped moving, take your permanent marker and place a small, clear dot on the exact highest point of the ball. This dot represents the "light" pole of your golf ball. Congratulations, you’ve just found the ball’s center of balance!

Coach's Tip: If the ball keeps spinning and never settles on one spot, you’ve found a perfectly balanced sphere! These are the keepers. Set them aside for important tournament rounds.

Step 4: Confirm Your Finding

To be sure, gently flick the ball or push it under the water and let it resettle on its own. A truly imbalanced ball will rotate back to the exact same position, with your dot facing straight up. Repeat this two or three times to confirm. If it consistently stops with the dot at the top, you have positively identified the imbalance.

Step 5: Repeat for All Your Balls

Take that ball out, dry it off, and repeat the process for every ball you plan to use. You might be surprised to find that even premium, expensive balls can have slight imbalances. It’s also common to find that one ball in a sleeve of three is balanced while the other two are not.

How to Use a "Balanced" Golf Ball on the Course

Now that you've identified the light and heavy poles of your golf balls, how do you use this information to your advantage? It’s all about alignment.

Imagine the dot you marked (the light side) is the North Pole of your ball. Naturally, the point on the opposite side is the South Pole (the heavy side). The most stable axis of rotation is the line that runs exactly around the middle of the sphere between these two poles - the equator.

For Perfect Putts

This is where your work will pay off the most. After finding the light pole, take the ball and draw your putting alignment line around this "equator." Your line should be exactly perpendicular to the axis created by the light and heavy poles.

Here’s how to visualize it: Hold the ball so your marked "light pole" dot is facing the ceiling. The heavy side is directly underneath. Now, draw your line straight around the middle of the ball. This line represents the path of a pure, end-over-end roll.

When you place your ball on the green, simply aim this equator line down your intended target line. When you strike the putt, the ball will roll naturally on its most stable axis, without the tendency to wobble or drift as it loses speed. It removes a massive variable from putting, giving you peace of mind that if you miss, it was because of your read or your stroke, not your equipment.

On Tee Shots and Approaches

The logic for full shots is similar, though the benefits aren’t quite as dramatic as with putting. To promote the most stable flight possible, you want the ball to rotate around its stable equator, just like with a putt. To do this, simply align the poles of the golf ball horizontally, parallel to the ground.

In other words, you want the light and heavy spots pointing to the sides. With your equator line now facing the target, the spinning ball is less likely to deviate from its intended flight path. It encourages a more powerful and stable spin axis, much like how a quarterback throws a tight spiral.

Final Thoughts

Checking your golf balls for balance is a simple, effective way to remove one more tiny variable from this beautifully complicated game. By using the salt float test, you can ensure that the ball you're striking rolls as true as possible on the greens, giving you a tangible edge and more confidence over every putt.
