ISI K Loft Intelligence
These derived specs show how the numbered irons are structured beyond the raw loft chart.
34.5° loft
vs ~35° traditional 7i
3.5° average
Moderately varied
Iron-only spacing: The tightest numbered-iron gap is 2.5° from 2i to 3i; the widest is 4° from 6i to 7i.
Loft Consistency Score: 61.8/100. This derived score measures variation in numbered-iron loft gaps; 100 means perfectly even spacing.
How the ISI K lofts affect the shot
Loft is one of the biggest inputs into launch, trajectory, rollout and stopping power. The table below translates each ISI K loft into its likely loft-only shot tendency.
Low launch • Higher roll
Very high launch • Maximum stopping
Low → Very high launch tendency
Distance → control as loft increases
| Club | Loft | Launch Tendency | Flight Window | Roll Tendency | Stopping Tendency | Loft-Driven Role |
|---|---|---|---|---|---|---|
| 1i | 15.5° | Low | Penetrating | Higher | Low | Long-iron distance slot |
| 2i | 18° | Low | Penetrating | Higher | Low | Long-iron distance slot |
| 3i | 20.5° | Low–mid | Strong | Moderate–high | Low–moderate | Long-iron slot |
| 4i | 24° | Low–mid | Strong | Moderate–high | Low–moderate | Long-iron slot |
| 5i | 27° | Mid–low | Strong / flat | Moderate | Moderate | Distance-biased mid/long iron |
| 6i | 30.5° | Mid | Balanced | Moderate | Moderate–high | Mid-iron scoring transition |
| 7i | 34.5° | Mid–high | Higher | Low–moderate | High | Control-oriented mid/short iron |
| 8i | 38.5° | High | High / soft | Lower | High | Short-iron approach slot |
| 9i | 42.5° | High | High / steep | Low | Very high | Scoring-iron / pitching slot |
| PW | 47° | Very high | Very high / steep | Very low | Very high | Gap-control / scoring slot |
| UW | 49.5° | Very high | Very high / steep | Very low | Very high | Gap-control / scoring slot |
| SW | 52° | Very high | Maximum-height / steep | Minimal | Maximum | Short-game / maximum-control slot |
| S2 | 54.5° | Very high | Maximum-height / steep | Minimal | Maximum | Short-game / maximum-control slot |

| LW | 61° | Very high | Maximum-height / steep | Minimal | Maximum | Short-game / maximum-control slot |
What the loft gaps mean for shot separation
- 1-iron → 2-iron: 2.5° — Tight loft step — higher chance of compressed carry spacing.
- 2-iron → 3-iron: 2.5° — Tight loft step — higher chance of compressed carry spacing.
- 3-iron → 4-iron: 3.5° — Normal-to-moderate loft step — usually a balanced transition.
- 4-iron → 5-iron: 3° — Normal-to-moderate loft step — usually a balanced transition.
- 5-iron → 6-iron: 3.5° — Normal-to-moderate loft step — usually a balanced transition.
- 6-iron → 7-iron: 4° — Normal-to-moderate loft step — usually a balanced transition.
- 7-iron → 8-iron: 4° — Normal-to-moderate loft step — usually a balanced transition.
- 8-iron → 9-iron: 4° — Normal-to-moderate loft step — usually a balanced transition.
- 9-iron → pitching wedge: 4.5° — Wider loft step — worth checking carry distance for a larger jump.
- pitching wedge → utility wedge: 2.5° — Tight loft step — higher chance of compressed carry spacing.
- utility wedge → sand wedge: 2.5° — Tight loft step — higher chance of compressed carry spacing.
- sand wedge → S2: 2.5° — Tight loft step — higher chance of compressed carry spacing.
- S2 → S3: 2.5° — Tight loft step — higher chance of compressed carry spacing.
- S3 → lob wedge: 4° — Normal-to-moderate loft step — usually a balanced transition.
Iron note: Stronger lofts generally lower the launch/flight window and increase distance potential, while weaker lofts generally raise flight and stopping power. Modern iron head design can counteract some of that, so this is a loft-only tendency rather than a measured launch result.
Where the set changes from distance to control
By loft alone, the distance-biased part of the numbered set extends through roughly the 5-iron at 27°. By the 7-iron at 34.5°, the loft profile is clearly moving toward higher launch, steeper descent and stronger green-holding tendency.
ISI K distance-to-control map
| Part of lineup | Reference club | Loft | What the loft favors |
|---|---|---|---|
| Distance end | 1-iron | 15.5° | Low launch, higher roll, stronger distance bias |
| Middle | 8-iron | 38.5° | High launch, more balanced carry/control role |
| Control end | lob wedge | 61° | Very high launch, maximum stopping tendency, stronger control bias |
Spec note: Loft can vary with model year, region, special configuration or custom fitting. Verify an exact club against PING documentation or measurement when a single degree matters.
