ISI 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 lofts affect the shot
Loft is one of the biggest inputs into launch, trajectory, rollout and stopping power. The table below translates each ISI 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 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.
