Bars show the relative progression within this model, not a comparison with other clubs.
What the numbers mean
Playing length is a build specification, not a universal fitting target.
How this length compares
Only genuinely comparable Cobra entries are used; women, junior and ONE Length builds are not mixed with standard men’s builds.

Cobra 3100 I/H length FAQs
What is the 3100 I/H length range?
The listed lengths run from 35.25 in (89.5 cm) to 38.5 in (97.8 cm), a total spread of 3.25 in (8.26 cm). The longest listed club is 4-iron and the shortest is SW.
How long is the 3100 I/H 7-iron?
The listed 7-iron playing length is 37 in (94 cm). Across this model, that sits 1.5 in below the longest listed club.
How does length change through the 3100 I/H set?
The listed progression generally gets shorter as loft increases. The typical step between adjacent listed clubs is about 0.5 in (1.27 cm), with a full longest-to-shortest change of 3.25 in.
How do loft and length relate in the 3100 I/H set?
For the matched entries in this dataset, 4-iron is 22° at 38.5 in (97.8 cm), while SW is 54° at 35.25 in (89.5 cm). That shows the actual model-specific loft/length progression rather than a generic fitting rule.
Is the 3100 I/H length a model-specific factory-published figure?
Not in the source record used here. The master dataset flags the length as reconstructed from the nearest Cobra family/generation standard because a complete model-specific factory length table was not available. Treat it as a reference value and verify before cutting or ordering a shaft.
