What the numbers mean

Playing length is a build specification, not a universal fitting target.

Player height, wrist-to-floor measurement, posture, strike pattern and swing-weight goals can justify a different finished length. Changing shaft length can also change lie interaction and feel.

Quick read: Match the loft and lie values with the exact club labels shown in the length chart above. That matters more than using a generic iron set spec when you are trying to match an original build.

Data provenance

About this length data

Length data note: These lengths come from the compiled Cobra specification dataset. The available source notes do not separately identify the length as a model-specific factory publication, so the page does not present it as one.
