Measuring a golf club's length is an important preliminary step in many club-making techniques. The length of a golf club is the length of the shaft and the club-head combined. There are different ways to measure a golf club, and the key is consistency. One of the most common ways is to measure the club before the grip is installed, as the thickness of the grip can vary depending on the model. The USGA, for example, measures to the very end of the grip cap and not the edge, which can increase the length by approximately 1/8. Another method is to place the club completely flat on the ground, with the contact point in the middle of the club's sole, and then measure to the end of the grip.
| Characteristics | Values |
|---|---|
| Maximum length | 48" for any club, excluding putters, according to the USGA |
| Maximum length (Model Local Rule G-10) | 46" for any club, excluding putters |
| Maximum length (LDA) | 50" |
| Correct resting position | Club should be placed flat on the ground, with the middle of the sole touching the ground |
| Correct measurement | From the middle of the sole to the end of the grip |
| Grip cap | Including the grip cap can add approximately 1/8" to the measurement |
| Putter length | No standard method due to different putter neck types, but generally measured through the center of the putter's sole |

Positioning the club
When measuring the club, it is important to use a consistent method. One common approach is to measure the club before installing the grip. This method accounts for variations in grip thickness between models and eliminates any guesswork. Additionally, it is beneficial for club builders as it simplifies the process if repairs are needed. However, when building a driver to the USGA maximum limit, excluding the grip in the measurement can lead to non-conformity once the grip is installed.
Another factor to consider when positioning the club is the type of club being measured. For putters, various methods can be used due to the different putter neck types. One approach is to direct the ruler through the centre of the putter's sole, rather than placing it at the heel. This adjustment accounts for the unique shaft position in offset putters, where the shaft is ahead of the putter face.
To ensure consistency in club measurement, it is recommended to use a jig or fixture specifically designed for this purpose. For instance, the Dynacraft Bench Ruler Soleplate, used in conjunction with a 48-inch aluminium ruler, provides an accurate and inexpensive way to measure club length.
In summary, accurate positioning of the golf club during measurement requires a flat orientation with the sole centred on the contact point. Consistency in the chosen measurement method and consideration of club type are also key factors in achieving precise results.

Using a ruler
To measure a golf club using a ruler, you will need a flat surface and a ruler that is at least 48 inches long. If you don't have a long enough ruler, you can make your own "USGA standard" ruler by drawing a pyramid on a letter sheet and following the instructions provided on some golf forums.
First, prepare your measurement area by placing the golf club on a flat surface. The club should be in a playing position, with the toe of the club pointing up so that the shaft is lying flat. If you are measuring a driver, fairway wood, hybrid, iron, or wedge, place the club in the playing position with the centre of the sole touching the ground.
Next, position the ruler so that it runs from the ground up to the end of the grip cap. Ensure that the ruler is touching the end of the grip and is parallel to the shaft. The measurement from the ground to the top of the grip is the length of the golf club.
For drivers and irons, you can measure from the end of the grip to the heel of the club. For putters, measure from the top of the grip to the bottom sole of the club. If you are measuring a non-offset, centre-shafted putter, you can place the ruler alongside the putter's shaft at the point it intersects the ground up to the edge of the grip cap. For an offset putter, place the ruler along the backside of the shaft.
It is important to note that the lie of the club can affect the final length. The lie refers to the angle between the shaft and the ground when the club is in a playing position. If the toe of the club is raised higher off the ground than the heel, the measurement will be less than if the centre of the sole is touching the ground. Conversely, if the heel is raised higher than the toe, the measured length will be increased.

Measuring the shaft
Preparation
Before beginning the measurement process, it is essential to have the right tools. A 48-inch ruler or a tape measure is ideal for this task. It is also important to ensure that the golf club is in the correct playing position, with the centre of the sole touching the ground. This will provide a consistent reference point for measurement.
Measuring Process
Stand in your natural address position, as if you were about to hit a shot. This ensures that the measurement reflects the actual length of the shaft during play. Align the ruler or tape measure with the shaft of the golf club, starting from the ground up to the end of the grip. It is crucial to maintain the alignment of the measuring tool with the shaft to obtain an accurate reading. Take into account your height and arm length for a proper fit, and consider seeking professional advice for precise adjustments.
Common Variations
There are a few variations in measuring the shaft length. One method involves measuring the club before the grip is installed. This approach eliminates the variability in grip thickness between different models, ensuring a more precise measurement. However, this method may not be suitable if building a driver to the USGA maximum length limit, as the club may become non-conforming once the grip is added. Another variation is specific to putters. When measuring heel-shafted putters, the length can be determined similarly to irons or woods. For centre-shafted putters, the measurement is taken along the shaft axis, while for offset putters, the ruler is placed along the back side of the shaft.
Avoiding Common Pitfalls
It is important to note that placing the golf club directly against a wall to measure from the sole is not the correct way. This method often leads to confusion and inaccurate conclusions about the club's length. Consistency in the measurement process is crucial to obtaining reliable results.

Putter length
Putters come in different lengths, weights, and head shapes. When it comes to putter length, your height, body composition, arm length, and any injuries you may have will all play a role in determining the ideal size for you.
There are several methods for determining the length of a putter. One common approach is to measure from the centre of the club face, up the shaft, to the butt end of the grip. This can be done by placing the putter head on a flat surface, such as a putting green, indoor mat, or carpet, and then using a measuring tape or yardstick to measure from the centre of the club face to the top of the grip, ensuring that the measuring device stays as close to the shaft as possible. The resulting number is the putter length.
Another factor to consider when determining putter length is the distance from your arms to the ground. This is typically measured from the sole of your shoe to the tip of your finger with your arm extended downwards while standing straight. While this measurement does not dictate that your putter should be the same length, it serves as a useful starting point.
The United States Golf Association (USGA) outlines a specific method for measuring club length in its Rules of Golf. They employ an apparatus with a 60-degree angle iron stop. The USGA measures to the end of the grip cap, adding approximately 1/8" to the measurement. Additionally, the USGA imposes a 48" limit on club length, excluding putters, which have no length restrictions.

USGA regulations
The USGA has strict regulations for measuring a golf club. The overall length of the club must be at least 18 inches and must not exceed 48 inches, except for putters, which do not have a specified length limit. The USGA uses an apparatus with a 60-degree angle iron as a stop to measure the distance from the point of intersection between the two planes to the top of the grip. This method ensures consistency and accuracy in measuring club length.
For woods and irons, the measurement is taken when the club is on a horizontal plane and the sole is set against a 60-degree plane. The length is then defined as the distance from the point of intersection of the two planes to the top of the grip. This measurement technique is different from the one used by the Long Drivers of America (LDA), who place the shaft flat against the wall with the toe of the driver on the ground, resulting in a longer length measurement.
The USGA regulations also specify that a club must be composed of a shaft and a head and may have material added to the shaft for a firm grip. All parts of the club must be fixed, with no external attachments that could affect the club's performance. A club must also not be substantially different from the traditional and customary form and make.
Additionally, the USGA has introduced a new Model Local Rule (MLR G-10) that allows organisers of professional or elite amateur golf competitions to limit the maximum length of a golf club (excluding putters) to 46 inches. This rule aims to standardise club lengths and minimise inconsistencies in relief areas between players, as the longest club is now used for measuring, eliminating the advantage for those who previously used longer clubs for strategic gain.
