In a traditional set of irons, each club is a different length: long irons are longer and short irons shorter, typically by half an inch per club. One-length (or single-length) irons are all built to the same length, usually that of a 7-iron, with the same lie angle and swing weight. The idea is simple: one set-up, one ball position and one swing for every iron. But do they work? Here's what you need to know.
How one-length irons work
| Traditional irons | One-length irons | |
|---|---|---|
| Length | Varies by about half an inch per club | Same for every iron |
| Lie angle | Varies | Same |
| Swing weight | Same feel, different club weights | Same head weight |
| Loft | Varies | Varies |
| Ball position and set-up | Varies slightly | Same |
Distance differences come mainly from loft rather than length.
Potential benefits
- Consistency: the same posture, ball position and swing.
- Easier long irons: a shorter long iron can be easier to control.
- Simplified practice: one set-up to learn.
- Possibly easier fitting: one length and lie to get right.
Potential drawbacks
- Long irons: with less length, long irons may not go far enough, and gaps can shrink. Many golfers replace them with hybrids anyway. Read hybrid golf clubs explained.
- Short irons and wedges: at a 7-iron length, short irons are longer than normal and may fly further or feel different.
- Feel: they feel different, especially at first.
- Limited choice: fewer manufacturers offer them.
- Wedge transitions: if your wedges are standard length, the change can feel odd.
Who might benefit?
- Golfers who struggle with inconsistency through the set.
- Beginners who want a simple set-up.
- Golfers who like the idea of "one swing".
- Tall golfers who find short irons too short (with appropriate fitting).
Who might not?
- Golfers happy with their current gapping and consistency.
- Low-handicap golfers who rely on precise distance control with short irons.
Getting fitted
As with any irons, length, lie, shaft and grip should be fitted to you. Check distance gaps on a launch monitor. Read custom golf club fitting, what clubs to carry and launch monitor numbers explained.
Frequently asked questions
What length are one-length irons?
Usually around the length of a traditional 7-iron, though it varies by manufacturer and fitting.
Do one-length irons go the same distance?
No. Loft varies through the set, so each club still goes a different distance.
Are one-length irons good for beginners?
They can be, thanks to the simple set-up, but try them before buying.
Can I mix one-length and traditional clubs?
Yes. Many golfers use one-length irons with traditional woods, hybrids and wedges.
The bottom line
One-length irons offer a simpler, more consistent set-up, but can create gapping challenges at the ends of the set. If you struggle with consistency, try them on a launch monitor and compare gaps before you decide. For more on irons, read game improvement vs players' irons.
