What stands out about the Quantum Max OS lofts?
Gap pattern: Median gap is 4°. Tightest: 4i→5i (3°), 5i→6i (3°). Widest: 9i→PW (5°), PW→AW (5°).
Quantum Max OS loft progression
The 29° 7-iron is the clearest single reference point for how this set is lofted. Loft helps explain distance structure, but it does not by itself predict launch, spin or carry.
Where are the tightest and widest loft gaps?
The tightest static gap is 3° between 4-iron and 5-iron. The widest is 5° between 9-iron and pitching wedge. Those are the first transitions worth checking if real carry gaps look compressed or stretched.
Quantum Max OS vs other Callaway iron lofts
This comparison uses the same benchmark club where possible and deliberately shows nearby lower, similar and higher lofts when available.

| Apex Ai300 | 7i | 29° | Same loft |
| Apex Ai300 Black | 7i | 29° | Same loft |
| Apex | 7i | 30° | 1° higher loft |
| Elyte X | 7i | 28° | 1° lower loft |

Quantum Max OS Loft Intelligence
These derived specs show how the numbered irons are structured instead of only repeating the factory lofts.
29° loft
vs ~35° traditional 7i
3.6° average
Moderately varied
Iron-only spacing: The tightest numbered-iron gap is 3° from 4i to 5i. The widest is 4° from 6i to 7i.
Progression shape: The long irons are more compressed at 3° average spacing versus 4° through the mid/short numbered irons.
Loft Consistency Score: 66/100. This derived score measures variation in numbered-iron loft gaps. A score of 100 means perfectly even static-loft spacing.
Spec note: Factory lofts can vary by model year, region, handedness or special configuration. Verify an exact club against Callaway documentation when a single degree matters for fitting, replacement or bending.
