Swing weight is a letter and a number that says how head-heavy a club feels. The scale runs from A0 (lightest) to F9 (heaviest), and each step up adds 1.75 ounce-inches. Hireko and a clubmaking guide both put most men's clubs between C9 and D3, and women's clubs run lower: PING lists its G Le3 irons from C1 to C6. Half an inch of length is worth about 3 points, 2 grams in the head about 1 point, and 5 grams more in the grip takes about 1 point off.
The ChartThe swing weight scale, A0 to F9
Read it like a ruler. The letter is the band, the number is the step inside it, and D0 comes one step after C9. A swing weight scale balances the club on a point 14 inches from the end of the grip, and the reading is how hard the club pulls on that lever. Hireko's chart gives each reading in ounce-inches and in gram-inches.

Typical RangesTypical swing weights for men's and women's clubs
Each maker sets its own, so the published ranges overlap and disagree at the edges. Here they are side by side.
Ranges quoted by clubmakers and retailers
| Source | Men's | Women's | What it covers |
|---|---|---|---|
| Hireko Golf | C9 to D3 | Lower than men's, no range given | "Normal" swing weights at men's standard lengths with a 50 to 52 g grip. Hireko says shorter ladies lengths would be less. |
| Swingweight guide (PDF hosted by Advanced Ball Striking) | C9 to D3 | - | The vast majority of heads designed today, at a standard length (39 in 2-iron). |
| TGW | D0 to D2 | C5 to C7 | Off the rack with stock options. |
| Golf Monthly | Around D0 | Around C6 | Most sets of irons. |
| Mitchell Golf Equipment | D0 to D4 | C0 to C9 (ladies, juniors, some men); B0 to B9 (ladies, seniors) | D0 to D4 is "most men's off-the-shelf clubs". Mitchell draws the scale from A0 to E9; Hireko, TGW and Golf Monthly run it to F9. |

What PING prints on its spec pages
PING lists a swing weight for each club. Its G440 and G730 irons sit in the D band. The G Le3 sits in the C band from the hybrids to the sand wedge, and PING describes the G Le3 driver as built for slower-swing-speed women golfers.
| Club | G440 irons | G730 irons | G Le3 |
|---|---|---|---|
| 4 to 7 hybrid | - | - | C0 |
| 6-iron | D0 | D0 | C1 |

PING adds two notes. Standard swing weights for graphite-shafted G440 and G730 irons are 2 to 3 points lighter than shown, depending on shaft flex. On the G440 Max driver, the standard swing weight with a Project X Denali Red 60 shaft is 1 point higher than standard, and with a Mitsubishi Tensei 1K Black 65 it is 2 points higher.
Wedges run heavier
Hireko lists what to expect from off-the-rack wedges. The sand and lob wedges are listed at D4 to D5, above the D2 to D3 of the pitching and gap wedges.
| Club | Length | Swing weight range |
|---|---|---|
| PW | 35.75 in | D2 to D3 |
| GW | 35.50 in | D2 to D3 |
| SW | 35.25 in | D4 to D5 |
| LW | 35.00 in | D4 to D5 |
Source: Hireko Golf, Why Do Wedges Have a Heavier Swing Weight Than Irons?
Hireko and GolfWorks give the same reason: wedges are played from thick grass and sand and are swung slower, so extra head weight helps them get through. Britt Lindsey on RalphMaltby.com says a traditionally built iron set should hold one swing weight within about 1 point, and that wedges built to normal lengths usually land a few points higher. For a driver he gives D2 as about average: 45 in long with a 60 g shaft, a 50 g grip and a 200 g head.
What Moves ItWhat changes swing weight, and by how much
Head, grip, length, shaft weight and shaft balance point all move the number. The makers' rules of thumb are close but not identical, so where two sources differ, both are shown.
| Change | Effect on swing weight | Source |
|---|---|---|
| Head weight up 2 g | +1 point. Hireko puts the exact figure nearer 1.6 g for a 45 in driver and 2.3 g for a wedge. | Swingweight guide; GolfWorks FAQ; Hireko, Weight and Weight Distribution |
| Grip weight up 5 g | -1 point, because a heavier grip lowers swing weight. GolfWorks' Ralph Maltby treats a 5 g cut in the grip as about 2.5 g of head weight, which moves a D2 club to D3 or a little past it. | Swingweight guide; Hireko, Winn grip weight; GolfWorks FAQ |
| Length up 1/2 in | +3 points. Hireko's clubmaking specialist puts one inch at 6 points, about 10 g of head weight, and elsewhere says each 1/6 in is 1 point. | Swingweight guide; Hireko, Weight and Weight Distribution; GolfWorks FAQ; Hireko blog |
| Shaft weight up 9 g | +1 point in the guide, which labels the figure "for illustration purposes only". Hireko says about 7 g on a 45 in driver (6.5 g in its worked driver example) and about 15 g on a sand wedge. | Swingweight guide; Hireko, Weight and Weight Distribution; Hireko blog |
| Shaft balance point moved toward the butt | Lowers it. In Hireko's driver example a 65 g cut shaft reads D2.2 at a 48% balance point, C9.9 at 52% and C7.4 at 56%, measured from the tip. | Hireko, Head Weights, Shaft Weights and Balance Points |
| Lead tape on the head | 4 in of 1/2 in wide tape is 1 point. | Swingweight guide |
| Next grip size up (1/32 in oversize) | -1 point. | GolfWorks FAQ |
| Steel shaft to graphite, same head and length | GolfWorks' example: a 256 g 5-iron head at 38 in reads about D2 with a 115 g steel shaft and about C9 with an 87 g graphite shaft. | GolfWorks FAQ |
Source: Swingweight (PDF, Advanced Ball Striking); GolfWorks, Frequent Technical Questions (answers by Ralph Maltby); Hireko Golf, Modern Guide to Golf Club Fitting Chapter Twelve, Winn grip weight article, and blog post Why Swing Weight Is Lower with A Lighter Golf Shaft.
Some sources use 4 g per point for the grip instead of 5; the grip weight chart lays out both rules. The 2 g head figure is also a shortcut. The guide says a club 38 3/4 in long needs 2 g for a point, longer clubs a little less and shorter clubs a little more.
A worked example: driver shaft weight and balance point
Hireko ran one driver through a range of shaft weights: a 200 g head, a 50 g grip and a 45 in length. The first column of results assumes the shaft balances in the middle. The next three show what happens when the balance point sits nearer the tip (48%), in the usual spot (52%) or nearer the butt (56%).
| Raw shaft (g) | Cut shaft (g) | Balanced mid-shaft | 48% | 52% | 56% |
|---|---|---|---|---|---|
| 48 | 45.5 | C8 | C8.7 | C7.2 | C5.6 |
| 55 | 52.0 | C9 | C9.9 | C8.1 | C6.3 |
| 62 | 58.5 | D0 | D1.0 | C9.0 | C6.9 |
| 69 | 65.0 | D1 | D2.2 | C9.9 | C7.4 |
| 76 | 71.5 | D2 | D3.3 | D0.8 | C8.3 |
| 83 | 78.0 | D3 | D4.5 | D1.7 | C9.0 |
| 90 | 84.5 | D4 | D5.6 | D2.6 | C9.7 |
| 97 | 91.0 | D5 | D6.7 | D3.5 | D0.4 |
| 104 | 97.5 | D6 | D7.9 | D4.5 | D1.1 |
| 111 | 104.0 | D7 | D9.0 | D5.4 | D1.8 |
Source: Hireko Golf, Head Weights, Shaft Weights and Balance Points - Oh My! (balance point as a percentage of shaft length from the tip).
Hireko's own reading: a 45 g shaft takes three points off the mid-shaft D1 example, and a 105 g shaft takes it to D7. In the upper-60 g range, which is the most popular driver shaft weight, moving the balance point alone makes nearly a 5 point difference.
Using ItHow to use the chart
Get your number. A swing weight scale reads it straight off the club; GolfWorks sells one that reads C8, D2 and so on, and a club builder or fitter with a scale can read yours. Without a scale, Hireko's free assembled-club calculator needs the club's total weight and its balance point measured from the butt end.
Find it on the scale. Look up your reading in the chart above and in the ranges table. Remember that the step below D0 is C9.
Plan a change from the table. Hireko's example is a 78 g jumbo grip against a 50 g standard grip, which comes to about 5 points lower. Going the other way, Winn's Dri-Tac Lite is about 25 g lighter than the standard Dri-Tac, and Hireko puts that at about 5 points higher. The grip weight chart lists the published grip weights by maker.
Use length when weight will not do it. In Hireko's driver example a 190 g head reads C4 at 45 in and D0 at 46 in, and a 210 g head reads D6 at 45 in and D0 at 44 in. This is why standard lengths exist: GolfWorks says its standard lengths are set so swing weights land in normal ranges at standard head weights. See the club length chart for those lengths.
Do not chase one point. The guide compares a point to a dime sitting on the clubhead and says it is nearly imperceptible. An accomplished player can feel 2 points, and most average players start to notice 3. Britt Lindsey on RalphMaltby.com says he does not care what the number is as long as the head feel and overall weight feel right to the player, and that keeping the irons consistent matters more than matching the driver to them.
Players pick their own. Ralph Maltby, answering on the GolfWorks FAQ, says most tour pros play about 2 or 3 swing weights more than most golfers. He says he does not like driver swing weights under D0 and that many work best at D1 or D2. Hireko's 210 g example, D6, is one it says some players will find too head-heavy.
Watch forCommon mistakes
Treating swing weight as the club's weight. Mitchell Golf Equipment points out that a graphite-shafted club at 290 g total and a steel-shafted club at 420 g total can have the same swing weight. Hireko lists the club's overall weight and its swing weight as separate measurements.
Getting the grip backwards. A heavier grip lowers swing weight, and a lighter one raises it. The weight sits on the butt side of the 14 inch point.
Expecting a lighter shaft to make the club head-heavy. Hireko says the opposite happens: with the same length and balance point, a lighter shaft lowers swing weight, which is why the fixes Hireko lists after a re-shaft are more length or more head weight.
Carrying one maker's number to another. Hireko says each maker has its own chart, and PING says its graphite-shafted irons run 2 to 3 points lighter than the figures on its page. Compare a number only with the same kind of club, shaft and length.
Trusting a calculator to the point. Britt Lindsey calls the calculator he uses an estimator that could be off by a swing weight or two, and suggests dry fitting the parts and reading the scale before epoxy goes in.
FAQQuick answers
What is a normal swing weight for golf clubs?
Hireko and a clubmaking guide put most men's clubs at C9 to D3. TGW lists off-the-rack men's clubs at D0 to D2 and women's at C5 to C7. PING lists the G440 7-iron at D0 and the G Le3 7-iron at C2.
What does D2 mean in ounce-inches?
On Hireko's chart D2 is 217.00 ounce-inches, or 6152 gram-inches. Britt Lindsey on RalphMaltby.com says a 45 in driver with a 60 g shaft, a 50 g grip and a 200 g head comes out around D2.
Is a higher swing weight better?
There is no one right number. A higher number puts more of the weight in the head. Ralph Maltby says most tour pros play 2 or 3 points above most golfers, and Britt Lindsey says the right number is the one that feels right to the player.
How many grams make one swing weight point?
About 2 g in the head, about 5 g in the grip (it lowers the number) and about 9 g in the shaft in the guide's rule of thumb. Hireko says about 7 g of shaft on a 45 in driver. Half an inch of length is worth about 3 points.
Does a lighter shaft raise or lower swing weight?
It lowers it. Hireko says a 7 g drop on a driver is about 1 point, while a sand wedge needs about 15 g. Makers often add length to make it up, and Hireko says graphite-shafted irons can be up to 1/2 in longer than steel ones.
Can I find my swing weight without a scale?
Hireko's free calculator for assembled clubs needs the club's weight and its balance point measured from the butt end. Treat the result as an estimate, since the calculator Britt Lindsey uses can be a swing weight or two off.
