Glossary of Fitting Terms

A concise glossary explaining terms such as lie angle, swing weight, face angle, bounce, toe, heel, and shaft characteristics. Designed to reinforce understanding as readers navigate other guides.

In the quiet, almost intimate world of club fitting, terms are not mere labels but keys—openers to nuance, cadence, and the subtle physics that govern every swing. The Glossary of Fitting Terms is crafted as a portable compass: concise definitions that illuminate the terrain you’ll traverse in the larger guides, from Golf Club Fitting Basics to Key Fitting Measurements.

This section aims to demystify jargon without diluting specificity. We pull from a culture of precision—the language of engineers and instructors alike—yet we deliver with the cadence of a New Yorker profile: attentive, lucid, and tuned to the reader who wants to understand before acting.

The glossary is not merely a dictionary; it’s a map. Lie angle, swing weight, face angle, bounce, toe, heel, and shaft characteristics are not isolated signs. They are relationships that shape trajectory, feel, and consistency. As you flip from one guide to another, let these terms be your guiding thread, the way a reviewer threads context through a longform essay.

Where possible, we anchor terms in practical implications: how a measurement shifts a club’s performance, what feedback you should seek from a fitting pro, and how to interpret at-home assessments alongside professional insights. The aim is to empower you to read the data with as much nuance as you read a feature in a culture piece—curious, exacting, and a little reverent of the craft.

How to Use This Glossary

In the Club Fitter Knowledge Hub, precision is a habit. The glossary’s aim is to foster confidence—so you can engage more meaningfully with fittings, whether you’re at home with templates from Fit Tools and Templates or in a pro session.

Lie angle

The angle between the club shaft and the ground at impact. Incorrect lie can cause hooks or pushes and misalignment of the toe and heel.

Loft

The tilt of the club face relative to vertical. Loft largely determines starting trajectory and height.

Length

The overall measurement of the club from grip to head. Length interacts with swing plane and balance.

Swing weight

A feel-based measure of how heavy a club feels during the swing, balancing speed with control.

Grip size

The diameter surrounding the hands. Proper grip size enhances control, feel, and comfort.

Shaft characteristics

Includes flex, kick point, and material. These affect tempo, launch, and accuracy.
