Many golfers spend hundreds of pounds on golf balls every year but don’t always understand the technology behind them. In this blog, we’ll explain what the numbers on golf balls mean and how they can impact your game.
The numbers on golf balls provide important information about their design and function. Generally, there are three main types of numbers you’ll find on golf balls:
One-digit numbers are used to help identify your golf ball. For example, if you and your friends play with different numbers, you can all use the same brand of golf balls. If one player uses a ball numbered ‘2’ and another uses a ‘4,’ it’s easy to tell them apart. This system reduces the chance of accidentally using someone else’s ball.
Golf regulation rules suggest using a marker to identify your ball, with many professional golfers using permanent markers to add dots or symbols. In theory, this means that even if two players choose a Callaway 2 ball, the symbols will help them identify their ball.
Single digit golf balls are typically numbered between 1 and 4, however, they can go up to 9 in some cases. Some brands will also colour the digit on the ball making them even more recognisable.
The numbers on two-digit balls can vary depending on the brand and the model of the golf ball. Golfers can also customise their ball numbers or personalise them when purchasing directly from manufacturers.
You can purchase two-digit balls with numbers ranging from 10 to 99. These balls often come with compression ratings, which determine their hardness. A higher compression rating indicates a harder ball.
When selecting the right golf ball for your game, it’s important to choose one that offers the most distance. Typically, juniors and seniors prefer reduced compression balls, while stronger, younger golfers often opt for higher compression to maximise distance.
To identify a golf ball’s compression look for a small 80 or 90 on its side.
Three-digit golf balls typically indicate the number of dimples on the ball, as dimples increase air time and help the ball fly straighter. Most commonly, these balls have the number 300, but some brands have experimented with other numbers, such as 322.
Three digit numbered golf balls aren’t seen often as this is something many manufacturers have discontinued. If you spot one, this is a sign that the golf ball is more than a few years old.
