Standard Iron Lengths by Brand: Complete Club Length Comparison Chart
Standard 5-iron lengths range from 38.00″ to 38.75″ across major brands; most 7-irons are 37.00″ except Mizuno (37.25″) and PXG (37.50″). Use the table below to compare exact specs, then follow the measurement and fitting steps to confirm your set matches.
Specs/Reference Table
All lengths are measured at a 60° lie angle per USGA specifications. The typical increment between clubs is 0.5 inch. Add +0.5″ for overlength, subtract –0.5″ for underlength.
| Brand | 5-Iron Length | 7-Iron Length |
|---|---|---|
| TaylorMade | 38.00″ | 37.00″ |
| Callaway | 38.50″ | 37.00″ |
| Titleist | 38.00″ | 37.00″ |
| Ping | 38.25″ | 37.00″ |
| Mizuno | 38.25″ | 37.25″ |
| Cobra | 38.50″ | 37.25″ |
| Srixon | 38.00″ | 37.00″ |
| PXG | 38.75″ | 37.50″ |
Note: Lengths may vary within a brand’s model families (e.g., game‑improvement vs. player’s irons). The numbers above represent the most common standard offering.
How to Check and Confirm Iron Lengths
What you need: A 48″ ruler or club‑specific measuring gauge, a lie‑angle protractor (or a known 60° surface), and a flat table or bench. If you don’t have a gauge, many pro shops will measure your irons for free in under five minutes.
Ordered Action Steps
-
Sole the club at 60°. Place the clubhead on a flat surface so the sole is flush. On most irons the standard lie angle is 60° — verify this for your brand (some models may be 62° or 63°; check the spec sheet). If you cannot confirm the lie angle, assume 60° and note that any deviation shifts the measured length by roughly 0.08″ per degree.
-
Measure from hosel to grip. Using the ruler, find the center of the hosel (where it meets the ferrule) and measure straight up to the butt end of the grip. Record the number. Do this for your 5-iron and 7-iron.
-
Compare to the table. If your 5-iron reads within ±0.1″ of the brand’s standard, your set is stock. If it reads off by more than 0.1″, the club may be cut incorrectly or previously adjusted.
Branch check: If your 5-iron length matches the table but your 7-iron is 0.25″ longer or shorter than expected, verify the increment between clubs. Most brands use a consistent 0.5″ step. If the gap between 5-iron and 7-iron is 1.0″ (e.g., TaylorMade), the increment is standard. If the gap is 1.25″ (e.g., Mizuno), your set may have a non‑uniform progression — contact the manufacturer to confirm the intended 6-iron length.
Verification that your lengths are correct: After measuring all irons, lay the set in order on a flat surface. The increase from each club to the next should be visually consistent (0.5″ or the brand’s stated increment). If one club sticks out or sits visibly short, measure it again and compare to the spec table. A consistent progression across the set confirms the lengths are stock.
Common Mistakes and Failure Patterns
Symptom: You measure a 5-iron at 37.75″ when the spec says 38.00″.
Likely cause: The club was measured at a lie angle other than 60°. If the lie is 2° flatter, the length can read 0.16″ shorter.
Safer next move: Re‑measure with the club soled at a confirmed 60° lie angle. If you don’t own a protractor, take the club to a fitter. Many golfers unknowingly have irons bent 2–3° flat or upright from factory spec.
Symptom: All clubs measure correctly but performance is inconsistent.
Likely cause: The grip is not fully seated or is offset, adding or removing effective length. Pull the grip and reinstall it flush. Grip alignment errors can shift length by 0.1–0.2″.
When to Stop and Escalate
Stop DIY steps if you measure a length that differs by more than 0.25″ from the brand standard and you cannot verify the lie angle. At that point the club may have been altered or the head is not standard. Take the iron to a certified club fitter or the brand’s warranty department. Do not cut or adjust the shaft yourself — you may invalidate the warranty.
Key Takeaways
- Majority of brands (TaylorMade, Titleist, Srixon) use a 38.00″ 5‑iron and 37.00″ 7‑iron.
- Longer 5‑irons come from Callaway and Cobra (38.50″) and especially PXG (38.75″).
- Mizuno and Cobra add 0.25″ to the 7‑iron vs. the 37.00″ baseline.
- Increment check: Most brands use a 0.5″ step between clubs. If the 5‑iron and 7‑iron are 1.00″ apart (e.g., Titleist), the 6‑iron sits at 37.50″. If they’re 1.25″ apart (e.g., Mizuno), verify the 6‑iron length — it may also be 0.5″ from each neighbor.
- Lie angle matters: A club 0.25″ longer effectively sits about 0.5° more upright. If you have a non‑standard lie, the effective length changes.
- What you can do now: Pick a brand, note its 5‑iron and 7‑iron lengths, then measure your own set with a ruler at 60° lie angle. If they match, your lengths are stock. If not, use the decision branch above.
FAQ
How is standard iron length measured?
Standard length is measured from the center of the hosel to the butt of the grip, with the club soled at a 60° lie angle per USGA specifications.
What if my iron set has a different increment than 0.5″?
Most modern sets use a 0.5″ difference between clubs. Some brands (e.g., Mizuno) occasionally use a 0.25″ offset in longer irons; always check the spec sheet for the exact model.
Can I mix brands and still have correct length progression?
Yes, as long as you maintain a consistent 0.5″ increment. If you switch brands mid‑set, confirm the 5‑iron length of the new brand matches the target length for that club.
Do game‑improvement irons have different standard lengths?
Not typically — the standard length for a given brand/model line is usually the same across categories (player’s, game‑improvement, super‑game‑improvement). The differences are in offset, sole width, and head design, not length.
What is the practical effect of a 0.25″ length difference?
A quarter‑inch change alters effective lie angle by roughly 0.5° and swingweight by about 1.5 points. Most players can feel the difference in turf interaction and face‑to‑ground relation, especially in the 7‑iron.
Should I order overlength or underlength?
Only if your static fit (wrist‑to‑floor measurement) or dynamic fit (impact tape/divot pattern) indicates a need. For most golfers, stock length is correct. A professional fitting is the best way to determine if custom length is right for your swing.
