7 Iron Swing Speed Chart: Iron Shaft Weight, Flex & Carry

The quick answer: the average 7-iron swing speed is 92 mph on the PGA Tour and 78 mph on the LPGA Tour (TrackMan). Iron shaft weight follows 7-iron speed: under 70 mph, 55–75g graphite; 70–80 mph, 85–100g steel; 80–90 mph, 100–120g; over 90 mph, 120–130g. Flex follows driver speed, so most golfers match their driver flex.

Amateurs swing slower. TrackMan’s average male golfer (a 14.5 handicap) swings the driver at 94 mph and the 6-iron at 80 mph, so his 7-iron is a little under 80. The charts below give the iron shaft weight for your 7-iron speed, where you sit on the flex chart by handicap, and how far a 7-iron carries at each speed. For driver speed itself, use our swing speed shaft flex chart.

7 Iron Swing Speed Chart: Iron Shaft Weight

Find your 7-iron club speed and read across. These are the same weight classes as our golf shaft weight guide; the last column lists real iron shafts from the True Temper and KBS spec tables that fall in each class.

Most stock iron sets ship with 95–110g steel, the middle of the chart. If you’re well under 70 mph or over 90 mph with the 7-iron, a stock set is probably the wrong weight for you. Our free Shaft Weight Calculator gives a driver and iron range from your driver speed.

Average 7 Iron Swing Speed (PGA and LPGA Tour)

TrackMan’s 2023 tour averages, from competition and range shots:

On our weight chart, the PGA Tour average sits in the over-90 class (120–130g) and the LPGA average in the 70–80 class (85–100g). TrackMan doesn’t publish an amateur 7-iron average. What it does publish is amateur driver speed by handicap from its Combine test, which is what sets your flex:

Between 90–99 mph you’re on the Regular/Stiff line, and tempo decides: smooth swings go softer, aggressive swings go stiffer. That band holds the average male golfer (94 mph), so many amateurs who play Stiff irons would do as well or better in Regular.

Driver Speed vs 7 Iron Speed

Your 7-iron moves slower than your driver because it’s a shorter club. In TrackMan’s tour data the 7-iron moves at about 80% of driver speed: 92 against 115 mph on the PGA Tour, 78 against 96 mph on the LPGA Tour.

The amateur gap is a little smaller: TrackMan’s average golfer swings the 6-iron at 85% of his driver speed, against 82–83% on tour. So treat any driver-to-iron conversion as rough. Our flex chart is keyed on driver speed because that’s the number most launch monitors and fitters quote; if you only know your 7-iron speed, get your driver measured too, or start from our Shaft Flex Calculator.

Iron Shaft Flex by Swing Speed

Iron flex comes from the same chart as driver flex, keyed on driver speed. Most golfers play the same flex through the irons as in the driver; some go a touch softer in the long irons for launch.

The full driver chart, with how to measure your speed and the signs you’re in the wrong flex, is on our swing speed shaft flex chart.

7 Iron Carry Distance by Swing Speed

How far a 7-iron carries at each driver speed, from our golf club distance chart:

For a 7-iron-speed reference, TrackMan’s tour averages carry 176 yards at 92 mph (PGA Tour) and 143 yards at 78 mph (LPGA Tour). Carry also depends on the loft of your 7-iron, which now varies by several degrees between sets, and on how centrally you strike it.

Best Iron Shaft for an 80 mph Swing Speed

It depends which club the 80 mph is from.

• 80 mph with the driver: Regular flex (75–95 mph). For the weight, measure your 7-iron speed and read the chart above, or put your driver speed into the Shaft Weight Calculator.
• 80 mph with the 7-iron: you’re on the line between the 85–100g and 100–120g classes, so a shaft around 100g fits: Dynamic Gold 95 (97g), KBS Tour Lite Stiff (100g) or Dynamic Gold 105 S300 (103g). That’s a touch faster than the LPGA Tour average (78 mph, with a 96 mph driver), which sits on our Regular/Stiff line, so tempo picks the letter.

What the Shaft Makers Say

True Temper, KBS and Nippon don’t publish a 7-iron speed chart for their iron shafts on their current sites. KBS says only that flex is “determined based on how fast a golfer swings” and that its MAX Graphite Iron “will fit players using ‘swing speed’ rather than the traditional ‘flex’,” though that page lists flex and weight, not mph. Nippon puts tempo first: “Generally for those who have a quick tempo, stiffer shafts work well and softer shafts fit better for slower tempo golfers.”

That’s the same tie-breaker our chart uses. Speed puts you in a band, and on a borderline your tempo decides.

How to Measure Your 7 Iron Swing Speed

Hit 7-irons on a launch monitor and read club speed, which TrackMan defines as “the linear speed of the club head’s geometric center just prior to first contact with the golf ball.” Don’t confuse it with ball speed: on tour, 7-iron ball speed is 1.34–1.38 times club speed (TrackMan’s smash factor), so a 123 mph ball speed is a 92 mph swing. Take the average of several solid shots, not your best one.

Frequently asked questions

What is the average 7 iron swing speed?

92 mph on the PGA Tour and 78 mph on the LPGA Tour, from TrackMan’s 2023 tour averages. TrackMan doesn’t publish an amateur 7-iron average; its average male golfer swings the 6-iron at 80 mph, so his 7-iron is a little slower.

What is my swing speed if I hit my 7 iron 165 yards?

On our distance chart, 165 yards falls in the 160–175-yard 7-iron band, which goes with a driver swing speed of 105+ mph. On tour, TrackMan’s averages carry 176 yards at 92 mph of 7-iron speed and 143 yards at 78 mph, so 165 yards sits between the two. Your 7-iron’s loft changes the answer.

What shaft flex do I need for my 7 iron swing speed?

Flex is set by driver speed: 75–95 mph is Regular, 95–110 mph is Stiff and over 110 mph is X-Stiff, with 90–99 mph the Regular/Stiff borderline. On tour, a 92 mph 7-iron goes with a 115 mph driver (X-Stiff) and a 78 mph 7-iron with a 96 mph driver (the R/S line).

What is the recommended club head speed for a stiff shaft?

95–110 mph of driver speed. Most golfers play the same flex in the irons. On the LPGA Tour, TrackMan measures 96 mph with the driver and 78 mph with the 7-iron, right at the bottom of the Stiff range.

What happens if your swing speed is too slow for a stiff shaft?

The shaft doesn’t load properly. You’ll see a lower ball flight, shots that fade or push right, less distance and a harsh, dead feel at impact. If that sounds like your irons, try Regular.

How heavy should my iron shafts be?

By 7-iron speed: under 70 mph, 55–75g graphite; 70–80 mph, 85–100g lightweight steel; 80–90 mph, 100–120g standard steel; over 90 mph, 120–130g. Most stock sets ship with 95–110g steel.

Can you hit a 300 yard drive with a regular flex shaft?

It’s unlikely to be the right fit. TrackMan’s PGA Tour average driver speed of 115 mph carries 282 yards, and that speed is in our X-Stiff band (over 110 mph). Regular flex is for 75–95 mph of driver speed.
