Irons
In short
Irons are golf clubs with a metal head and an angled clubface for shots from the fairway, the rough and onto the green. They are numbered, usually from 3 to 9. The higher the number, the shorter the club, the greater the loft and the shorter the distance. The 7-iron is regarded as the standard club.
Irons in golf: meaning and numbers
Irons are the most versatile group of clubs in the bag. Golfers use them for shots from the fairway, from light rough, from the short tee on par-3 holes and for approaches onto the green. The name dates from the time when the heads were forged from iron. Today they are usually made of steel.
Irons are numbered, usually 3 to 9. The wedges, such as the pitching wedge, often belong to the iron set as well. As a general principle: the higher the number, the shorter the shaft, the greater the loft, that is the angle of the clubface, and the higher and shorter the ball flies.
Golfers often divide irons into three groups:
- Long irons (3 and 4): hard to play, little loft, today often replaced by hybrids
- Mid irons (5, 6 and 7): the core of the set
- Short irons (8, 9 and pitching wedge): high ball flight, good control
The boundaries are fluid and depend on manufacturer and set.
Loft, length and distance: how irons differ
Two numbers decide how an iron flies: loft and length.
Loft: between neighbouring irons there are usually about three to five degrees. A 7-iron used to have a loft of around 34 to 36 degrees. Many modern sets have stronger lofts, and on some models the 7-iron sits around 28 to 31 degrees. The club therefore flies further but is still called a 7. So do not compare sets by the number alone.
Length: between two irons there is usually about half an inch, a little over a centimetre. The 7-iron for men is often around 37 inches, about 94 centimetres.
Distance: every iron has its own distance. As a guide, PGA Tour players carry the ball about 155 to 160 metres with the 7-iron according to published TrackMan averages. For club golfers the distance is clearly shorter. As a rule of thumb there are about 10 to 15 metres between two irons. You measure your own values best with a launch monitor and record them in a distance chart.
The 7-iron: the standard club
The 7-iron sits in the middle of the set. It is a good compromise of length, loft and control. That is why many coaches begin lessons with the 7-iron, and many golfers compare their distances with this club.
The 7-iron suits:
- shots from the fairway at medium distance
- par-3 holes of short to medium length
- range practice to train technique and rhythm
Beginners learn with the 7-iron to strike the ball cleanly before they tackle the long clubs. The shaft is short enough to keep the strike point, and the loft helps the ball into the air.
The 7-iron is also popular for measurements. Manufacturers and analyses often compare their numbers with this club. If you know how far your 7-iron flies, you can roughly derive the distances of the other irons.
Practical example: an approach with the right iron
Imagine a par 4 of 340 metres. Your tee shot flies 190 metres and sits in the middle of the fairway. It is 150 metres to the flag. The green is large, and a bunker sits in front of it at 125 metres.
You know your distances. Your 6-iron carries the ball 135 metres on average, your 5-iron about 145 metres. For 150 metres the 5-iron is slightly short, but the ball still rolls out a little. You choose the 5-iron and aim at the middle of the green. The ball lands in front of the flag and rolls to ten metres from the hole.
Had you chosen the 7-iron, the ball would probably have landed in the bunker. The example shows how important it is to know your own distances. Then you choose the club according to the hazards and not by feel. A par is easily possible here: two putts from ten metres make four strokes.
Building an iron set: how many irons do you need?
At most 14 clubs may be in the bag (Rule 4.1b). A common set-up looks like this:
- driver and 3-wood
- one or two hybrids
- irons 5 to 9 and pitching wedge
- gap wedge, sand wedge and lob wedge
- putter
That makes 13 to 14 clubs. Many club golfers drop the 3- and 4-irons and play hybrids instead, because these are easier to hit. A 5-iron is also often replaced by a hybrid.
Beginners often start with a half set or starter set. A half set usually contains only every second iron, for example 5, 7, 9 and pitching wedge. That is enough to learn. The set can be added to later.
When putting a set together, look for even gaps in distance. If two clubs fly almost the same distance, one of them takes up a place in the bag without adding anything. You will find more on this in the distance chart entry.
Typical mistakes with irons
The same mistakes appear again and again with iron shots.
- Fat shots: the club hits the ground before the ball. Common causes are weight staying on the back foot or the wrists releasing too early in the downswing. The ball flies short.
- Thin shots: the club hits the ball on its upper half. The cause is often the body straightening up during the swing.
- Ball too far forward or back: with short and mid irons the ball sits about in the middle of the stance. With longer irons it moves slightly forward.
- Hitting up at the ball: with an iron the club meets the ball on a slight downward path. The divot appears after the ball.
- Always the same iron: someone who practises only the 7-iron is unsure with the long and short clubs.
A coach usually recognises such mistakes after a few shots.
Tips: how to play irons more reliably
A few basics make your iron shots more stable.
- Strike the ball first: the club touches the ball first and the ground afterwards. The divot lies in front of the ball towards the target.
- Keep a calm tempo: rhythm matters more than power.
- Watch the ball position: mid irons about in the middle of the stance, longer irons slightly further forward.
- Choose the club by your distances: measure your carry distances and write them down.
- Practise with a target: pick a target on the range for every shot.
- Check the shaft: flex and length should suit you.
When you buy new irons, compare loft, length and shaft. A fitting helps to find the right set. And have a coach show you how to strike the irons cleanly.
Try it at Golf Lounge
On the Golf Lounge TrackMan range, three irons are ready at every mat, suitable for right- or left-handed players. There are 32 covered hitting bays on two levels, and at every bay TrackMan measures carry and total metres, launch angle and ball speed, among other values. The range can be heated and is usable all year. That lets you find your distances with the irons and record them in a chart of your own.
Frequently asked questions
What are irons in golf?
Irons are golf clubs with a metal head and an angled clubface for shots from the fairway, the rough and onto the green. They are usually numbered 3 to 9. The higher the number, the shorter the club, the greater the loft and the shorter the ball flies. The 7-iron is regarded as the standard club.
How far do you hit a 7-iron?
That depends on the player. As a guide, PGA Tour players carry the ball about 155 to 160 metres with the 7-iron according to TrackMan averages. Club golfers hit clearly shorter. Modern sets also often have stronger lofts than older ones. The best approach is to measure your own distance with a launch monitor and record the average.
Which irons do I need as a beginner?
A half set is enough at the start, for example 5, 7, 9 and pitching wedge. The long 3- and 4-irons are hard to hit, and many players use a hybrid instead. The set can be added to later. Even distance gaps and a shaft that suits your speed matter most.
How many irons belong in a golf bag?
At most 14 clubs may be in the bag. A common set-up is driver, fairway wood, one or two hybrids, irons 5 to 9, pitching wedge, two or three wedges and a putter. How many irons you actually carry depends on your game.
What is the difference between an iron and a hybrid?
A hybrid combines features of a wood and an iron. It has a wider, deeper head and is often easier to hit than a long iron. Many golfers therefore replace the 3- and 4-irons with hybrids. Irons remain the first choice for shorter distances and precise approaches.
