What do the numbers on your golf clubs stand for?

One of the most basic understandings of your equipment is knowing what information your clubs are giving, and what information they aren’t. The numbers (& letters) on the bottom of your iron set provide you with some information that can help you understand how they work. This may seem like entry-level information, but you may be surprised what these numbers and letters aren’t telling you as well. Let’s dive in with some help from our friends at Edel Golf and their SMS family of irons.

The numbers on the bottom of golf clubs primarily indicate the relative loft of each club. We say relative because these numbers are stated as a relationship to the loft structure of the iron set, and not the actual loft itself. As the number on the iron gets higher, that club has more loft, and if built properly, will also cover a shorter yardage gap by traveling a shorter distance.

The numbering system for golf irons typically starts from 1 and goes up to 9, although some sets may include additional irons or less irons. Today’s average golfer will typically play up to a 4 iron in their bag before switching to a different option. After 9, other than in some rare cases, the set will typically switch to letter designations for any wedges that are included in the set. We have a full breakdown on what all of those letters mean to each other which you can read here.

While loft can vary between different manufacturers and club models, there are general loft ranges associated with each number. These ranges provide a useful guideline for understanding the characteristics of each iron. It's important to note that these ranges can vary, and individual clubs may have slightly different lofts.

But does it matter…

While it may seem like a simple topic, understanding what and what isn’t said by the numbers on the bottom of your irons can really help your game. In today’s game there are varying opinions on what each of those numbers is actually supposed to technically mean in regards to the true specs of your clubs, but the best thing to do is drown out all that noise and just focus on what your equipment does for you. Know how it works, know what it does and you’ll play more confident golf.
