How Swing Weight Calculator Works

Select Mode: Choose between "Basic" for quick estimates (total weight & balance point) or "Advanced" for detailed calculations (club length, head, shaft, and grip weights).

Choose Units: Toggle between Metric (g/cm) and Imperial (oz/in) units for input and output. All calculations are handled internally for consistency.

Input Data: Enter your golf club's specifications into the respective fields. The calculator updates in real-time as you type.

View Results: Instantly see your club's "Lorythmic Scale" (Moment of Inertia), "Official Scale" (equivalent weight at fulcrum), and its "Swing Weight Grade" with a descriptive explanation.

Frequently Asked Questions

Swing weight is a measurement of how the weight of a golf club feels when you swing it. It is not the total weight, but rather a measure of the club's balance point, primarily influenced by the weight of the club head.

It is measured on a special scale with a fulcrum point 14 inches from the butt end of the grip. The measurement is expressed in an alphanumeric code, such as C9, D2, or E1.

A consistent swing weight across all clubs in a set helps promote a consistent feel and swing. Matching a club's swing weight to a player's preference can improve timing, rhythm, and confidence.

The scale runs from A0 (lightest feel) to G9 (heaviest feel). The letter (A-G) represents a range, and the number (0-9) is a fine-tuning step within that range. D2 is a very common swing weight for men's standard drivers and irons.
