Lofts and lies are the factory standard build. Individual clubs may differ if they have been bent, re-shafted or re-gripped during their life.
Length note: These lengths use the USGA / R&A measuring method, which Mizuno adopted for its published spec tables with this generation. They read about a quarter inch longer than the figures Mizuno published for earlier models such as the JPX923 and Mizuno Pro 241, 243 and 245, but Mizuno states that actual club length is unchanged. Subtract 0.25 inches to compare with an older Mizuno chart.

About the Mizuno JPX-925 Hot Metal
JPX 925 Hot Metal is Mizuno's mainstream game-improvement iron, redesigned for the generation with tungsten weighting through the 4 to 7 irons to raise launch where the loft is lowest. Lofts are strong — 28 degrees at the 7-iron, six stronger than the JPX 923 Tour — with a long 4-iron at 19 degrees, and offset is the widest in Mizuno's range at 0.224 inches at the top of the set. The set runs to a 54-degree sand wedge.

Where it sits in the lineup

New sets are built to the standard lofts, lies and lengths in the chart above, though a fitting can move any of them — so confirm the numbers on the order sheet. Used sets appear on eBay, and should be measured against this chart before buying.
- Length basis: Mizuno's own specification page for the Mizuno Pro 243 (mizunogolf.com, retrieved 29 September 2026) states that Mizuno is changing its official iron measurement method to match the USGA / R&A standard and that its published lengths are consequently about 1/4 inch longer while actual club length is unchanged.
