Golf club specifications explained

Read specifications as a set. A single number rarely predicts how a complete club will perform for an individual golfer.

Loft

The face angle relative to vertical in a defined measurement position. Static loft is the club's specification; dynamic loft is the delivered angle at impact.

Example: Two 7-irons can have different lofts, so the number on the sole is not a fair distance comparison by itself.

Lie angle

The angle between the shaft and the ground when the club is measured in its intended position. Delivered lie and sole contact are assessed during fitting.

Example: A fitting checks how the club reaches impact, rather than selecting lie from height alone.

Club length

The playing length measured using a defined club-measurement method. It affects setup and can influence speed and strike consistency.

Example: A shorter driver may improve center contact for a player even if potential clubhead speed changes.

Shaft flex

A manufacturer's description of shaft bending characteristics. Labels such as regular and stiff are not standardized across every product.

Example: Compare the actual shaft models at the same length and head, rather than choosing solely from the letter.

Shaft weight

The shaft's mass, normally listed in grams for a specified model and trimming state. It contributes to total weight and the feel of the club.

Example: A lighter shaft is not automatically faster for every player; test contact and control.

Torque

A measure of how much a shaft twists under a specified test. Manufacturer methods and the player's perception can differ.

Example: A low torque figure does not by itself guarantee a straighter shot.

Bend profile

How stiffness varies along the shaft. It gives more information than a single flex label but still needs testing in the complete club.

Example: Two stiff shafts can feel and perform differently for the same delivery.

Swing weight

A balance-scale measurement of the club's distribution of mass. It is not the club's total weight.

Example: Two clubs with the same swing-weight label can have different total masses.

Total weight

The mass of the complete club, including head, shaft and grip. It changes how much mass the golfer moves.

Example: Changing grip weight can alter both total weight and a swing-weight reading.

Center of gravity

The balance point of the clubhead's mass. Its location interacts with loft, strike and head design.

Example: A center-of-gravity claim is not a complete prediction of launch for your swing.

Moment of inertia

Resistance to angular acceleration about a particular axis. In a head, designers use mass placement to influence twisting behavior.

Example: Compare which axis and measurement a specification refers to; a single marketing number is incomplete.

Offset

The amount the leading edge sits behind the forward portion of the hosel under a defined measurement.

Example: Offset can change appearance and delivery response, but it does not guarantee a cure for a slice.

Bounce

The sole's angle relative to the ground in a defined address position. Sole width, curvature and face opening also affect turf interaction.

Example: Two wedges marked with the same bounce can behave differently because their soles are shaped differently.

Grind

Material shaping or removal from parts of a wedge sole. It can change how the sole behaves when the face is opened or the lie varies.

Example: Test a grind from your common lies instead of selecting it from a letter alone.

Grip size

The finished grip's dimensions and shape, influenced by the grip and underlying build-up.

Example: A comfortable fit should allow secure contact without forcing excessive pressure; hand measurement is only a starting point.

Adjustable hosels

Mechanisms that alter a club's installed configuration, often changing loft, lie or face presentation in linked ways.

Example: Read that model's chart and have the setting checked. Do not change playing characteristics during a round when the Rules prohibit it.
