What Number Is a Putter in Golf?

By Spencer Lanoue

Ever look at a bag of golf clubs and notice the neat sequence - 9, 8, 7, 6, 5-iron, your woods, and Wedges all have their own spot... but the putter seems to be the odd one out? It’s a great question, and the simple answer is that a putter does not have a number. This a special, unique club that's judged not by how far it hits the ball, but by how accurately it rolls it. This guide will explain why putters stand alone in the golf bag, how club numbers work for your other clubs, and most importantly, how you can understand the different types of putters to find the perfect one for your game.

The Simple Answer: A Putter Has No Number

Unlike irons and woods, a putter isn’t part of a numbered sequence. The numbers on other clubs (like a 7-iron or a 3-wood) are a shorthand for their loft and the distance they are designed to hit the ball. A higher number on an iron means more loft and less distance, while a lower number on a wood generally means less loft and more distance. The system provides a clear progression for hitting the ball various distances through the air.

The putter, however, has a completely different job. Its sole purpose is to roll the ball smoothly across the green and into the hole. It's not built for distance in the air, so stamping a "10" or a "1" on it wouldn't make much sense. It exists in its own category as the ultimate finishing tool. Think of it less like another club in the set and more like the surgeon's scalpel of your bag - specialized, precise, and used for the most delicate part of the operation.

So, Why Do Other Clubs Have Numbers?

To really appreciate why the putter is the exception, it helps to understand the rule. The numbering system on your other clubs is a brilliant, simple way to organize your tools for the different jobs you face on the course.

The Iron Numbering System

Your irons are your primary tools for approach shots into the green. The system is designed for precision yardage gaps.

  • A 9-iron has a lot of loft (the angle of the clubface). This sends the ball high into the air and makes it land softly, but it won't travel very far.
  • A 5-iron has much less loft. This produces a lower, more penetrating ball flight that travels a much longer distance.
  • The numbers in between (8, 7, 6) fill the distance gaps, with each club typically adding about 10-15 yards of distance as you go down in number.

It’s all about creating consistent spacing in distance so you can confidently pick the right club for an exact yardage.

What About Woods and Hybrids?

Woods and hybrids follow a similar logic, but they are built purely for distance. The Driver is often called a 1-wood, it has the lowest loft and longest shaft, designed for maximum distance off the tee. A 3-wood has more loft than a driver but less than a 5-wood, fitting neatly into the distance hierarchy. Hybrids are often numbered to directly replace their long-iron counterparts (e.g., a 4-hybrid replaces a 4-iron), offering more forgiveness and an easier launch.

The whole system is designed to give you a toolbox of different distances. Since the putter’s job is finesse and feel over a few feet - not pure yardage - it doesn’t need a number.

Meet the Putter: Your Scoring Superstar

While drivers get the glory and irons hit those satisfying shots onto the green, the putter is statistically the most important club you own. Don't underestimate its power. On average, putting accounts for around 40% of all your strokes in a round. That's a huge number! Saving a single putt per round by using a putter that fits you can drop your handicap faster than almost any other improvement.

It's the club you use to turn a good approach shot into a birdie, rescue a poor one for a par, and avoid those frustrating three-putts that ruin a scorecard. Mastering the putter won't just make you a better golfer, it will make you a better scorer.

The Hidden Science: The Loft of a Putter

Here’s a small detail that surprises many golfers: putters actually do have a little bit of loft. While it looks flat, a standard putter typically has between 2 to 4 degrees of loft. This isn’t a mistake. That tiny bit of loft is engineered to lift the ball ever so slightly out of the small depression it sits in on the green. This helps the ball get rolling smoothly on top of the grass immediately, rather than digging in or hopping at the start. It's a small but fundamental part of what makes a good putt roll true.

Understanding the Different Types of Putters

Because putters don't have numbers, manufacturers differentiate them by head shape, style, and technology. The two main categories you'll see are blade and mallet putters. Choosing between them comes down to your personal putting stroke and what looks and feels good to you.

Blade Putters: The Classic Choice

Blade putters are the traditional, simple design you probably picture when you think of a putter. They have a relatively small, thin clubhead and a very clean, straightforward look at address.

  • Best for: Golfers who have an "arcing" putting stroke. This means your putting stroke follows a slight arc, opening on the way back and closing through impact. Blades typically feature more "toe hang."
  • Feel: Blades provide excellent feedback. You can really feel the point of contact on the face. This is rewarding on good strokes but can be less forgiving on mis-hits.

Mallet Putters: Forgiveness is the Name of the Game

Mallet putters feature much larger, heavier clubheads that come in all sorts of shapes and sizes - from semi-circles to squares to geometric designs that look like something from a sci-fi movie.

  • Best for: Golfers who try to have a "straight-back, straight-through" putting stroke. The extra weight and design of mallets promote stability and resist twisting. They are often "face-balanced."
  • Forgiveness and Alignment: This is where mallets shine. The larger head size allows engineers to distribute weight to the perimeter, which makes the putter more stable on off-center hits. They also provide a bigger canvas for alignment aids, like long lines or multiple dots, which can be a massive confidence booster for lining up putts.

A Quick Note on Toe Hang vs. Face-Balanced

This sounds technical, but it’s a simple concept that can help you find the right style of putter for your stroke.

  • How to test it: Balance the shaft of the putter horizontally on your index finger.
  • Face-Balanced: If the face of the putter points directly up to the sky, it’s a face-balanced putter. This design is best for players with a straight putting stroke, as it naturally wants to stay square. (Mostly mallets).
  • Toe Hang: If the toe of the putter "hangs" down towards the ground at an angle, it has toe hang. The amount of hang can vary. This design works best with an arcing stroke, as it allows the face to naturally open and close with the path of the stroke. (Mostly blades).

How to Choose the Right Putter for Your Game

Beyond blade vs. mallet, a few other factors are extremely important in finding the putter that feels like an extension of your arms.

1. Putter Length

This is arguably the most important element. A putter that is too long or too short will force you into an unnatural setup, leading to bad posture and an inconsistent stroke. Proper length allows your eyes to sit directly over the ball and lets your arms hang comfortably.

Pro Tip: Go to a golf shop. Get into your comfortable putting stance and let your arms hang naturally. The ideal length is a putter whose grip meets your hands in that relaxed position. Most men use a 34" or 35" putter, and most women a 33", but getting measured is a game-changer.

2. Grip Style

Putter grips come in all shapes and sizes. The traditional grip is thin and pistol-shaped. However, oversized grips (like those from SuperStroke) have become very popular. A thicker grip can help quiet your hands and wrists during the stroke, promoting a more stable "rocking" motion with your shoulders.

3. Feel and Sound

How a putter feels at impact is deeply personal. Some putters have soft inserts on the face, which creates a muted sound and soft feel. Others have milledmetal faces, which can feel firmer and provide a more "clicky" auditory feedback. There is no right or wrong answer - you need to find what gives you the most confidence that the ball is coming off the face at the speed you intended.

Final Thoughts

While the putter may not have a number, it holds the most significant role in determining your final score. It’s a specialized tool built for rolling the ball, which is why it stands apart from the distance-based numbering of your irons and woods. Finding the right style - be it a blade for an arc stroke or a mallet for a straight one - along with the correct length and feel, can transform your confidence on the greens.
