Golf Club Loft – Will The Real Loft Please Stand Up

Posted by on Jun 14, 2012 in Clubfitting, Driver Fitting, Hybrid Fitting, Iron Fitting | 17 comments

One of the very most important specifications on each of your golf clubs is the loft angle.  To skip the fancy definitions, the loft angle is how much the face of the clubhead on each of your golf clubs is tilted back.  Every clubhead in your bag has a specific loft angle on the face, even your putter.

Quite simply, loft is about 85% of the reason you hit each golf club a different distance.  The length of each of your clubs comprises the other 15%.  How far YOU actually hit each club is mainly a product of the relationship of YOUR swing speed with the different loft on each clubhead in your set – with a couple of other technical things tossed in.

One of the several definitions of a perfect set of golf clubs is that each club hit the ball a specific, different distance and that the difference in distance between each club is as close to the same as possible.  Many of you know how frustrating it can be to play when you have two clubs that have a 20 yard distance difference between them and yet two others for which you only see about a 5 yard distance gap between.

When you see discrepancies in distance between clubs, the first and usually main reason this happens is because the lofts are not consistently spaced between all the clubs.  Yes, there are other reasons this can happen such as length errors or things associated with how much each club weighs in relation to the others.  But day in and day out, when you see inconsistent distances between clubs, it is because there is an error in the spacing of the loft angle(s) between the clubs.

So how DO you know what the lofts are on your clubs?  Sorry.  You can’t use a simple protractor to measure the loft on your clubs.  It takes a special gauge that club designers, clubhead production factories and custom clubmakers buy and use in their work.  While you can go to a the website of the company that makes the clubs you play and probably find a chart that tells you the loft on each head in your set, thanks to the fact there are definitely plus and minus tolerances, that doesn’t tell you exactly what your lofts are.

Add a really nasty thing to that as well. There are a number of golf companies who INTENTIONALLY make the real loft on their drivers to be different than what they say it is on the head! I kid you not. Since the late 90s, a few golf companies do this. Why?

Because they think they are doing golfers a favor.  Here’s the deal.  We all know there are some golfers out there who think they will hit the driver farther if it has a lower loft.  Many golfers do not know their optimum driver loft for maximum distance has to be chosen on the basis of the golfer’s clubhead speed AND their angle of attack into the ball.  Slower swing speed and/or more downward angle of attack means a higher driver loft is required to maximize distance.

Only when you have a high clubhead speed with an upward angle of attack do you get your max distance from a lower loft.  Starting in the 90s, several golf companies just found it was easier to lie about the loft on their drivers and make some of their driver models with more loft than they printed or engraved on the head.  More by like 2 degrees.

That’s fine I guess for the egotist golfers who refuse to buy a higher loft driver.  But for the many who do want to buy the right loft, it’s a real confusing situation.  Ultimately, it means to really know your lofts and to make sure your lofts match your swing, this is why it is so helpful to find and work with a competent custom Clubmaker.


  1. Clubs can be fit to compensate a golfers swing or swing flaws such upright lie angles for steep swing plane. Would flatter lie angle help trigger this same golfer to flatten his/her swing plane for a more efficient swing possibly eliminating an over the top / out to in downswing?

    • KENT

      It is possible for a golfer to let the way the clubs sit in the address position push the golfer into a different swing plane or different takeaway. The golfer has to consciously do this in the beginning with the adjusted clubs to get his swing change started. And then with discipline over time it is possible that the swing motion forced by the club change can stick. A flatter lie can certainly force the swing plane to be flatter, but there is no guarantee that it will also reduce the over the top outside in path problem. What makes most golfers do that is being over active with the hands and arms to start the downswing. Starting the club down with the HIP TURN and letting the hands and arms remain more passive until the turn is initiated is how most instructors try to re train the swing to reduce the over the top move. And that move cannot really be forced by any fitting change in the clubs. It has to be taught so the golfer understands clearly what it feels like to begin the downswing with the hip turn, then with a lot of practice to cement the feeling of that move to begin the downswing. A flatter lie won’t do that because it is eminently possible to go over the top regardless if you have a flatter or more upright plane.


    • Thanks for the response. Std.length upright lie looks and feels that I’m standing too erect. At age 52, turning on tightly stacked hips and back is becoming harder to do.

      I find that fitters will adjust lie angle but are reluctant to shorten club length. At 5’11 (closer to 6′ with golf shoes), my static fit specs indicate “standard” length clubs and dynamic swing requires 3* upright lie. Unless I’m practicing almost daily, I find that I make better contact by gripping down 1/2+” with the same lie angle.

      Should I ignore my fitter advice or get another fitter for second option? Is the fitter correct and I should just play as is, practice more?

    • KENT
      If there is another fitter who has a decent reputation for knowledge and experience, by all means you should consult to listen to a 2nd opinion. There are no “quality standards” for fitting knowledge because clubfitting has always been mostly a self taught “cottage industry.” In short there is a wide range in knowledge and expertise among fitters and always has been. One reason some fitters are reluctant to change length is because it is difficult to re swingweight the clubs after the length change. Sometimes the usual methods of a weight bore in the head or tip weight in the end of the shaft are not sufficient to get the swingweight where it needs to be after the length change. So that limits how you can achieve the right headweight to get the golfer into his best swingweight for the new length. And a lot of golfers really won’t go for lead tape on their clubheads. At the same time there is absolutely nothing wrong with gripping down as a number of tour pros do that – Fowler comes to mind as one. As long as you get the grip size comfortable for the amount you grip down, there is nothing wrong with that at all.


  2. You mentioned that a protractor cannot be used to measure loft of a given head. That special equipment is used by the manufacturer. Can you go into detail how the manufacturer measures their loft and given that using a protractor and understanding that because of the cupped face of a (driver face) it would be different from top to bottom; how much difference would there be? Also, using a protractor (or similar device) measuring one head i.e. stamped with a 9.5 degree loft and another stamped stamped with 9.5 and comparing the measurements obtained with the protractor (in the middle of the face); can any usable data be assumed?

    • Caleb:
      What I mean is that you cannot hold the clubhead in your hands and use a protractor to measure the loft. You must secure the clubhead in a special device and position it correctly before you then could use a special type of protractor to measure the loft. The video at this following you tube link can show you a little bit about the type of machine and how heads have to be fixtured in order to perform accurate spec measurements.

      Up until three years ago, all the manufacturers measured the loft of drivers/woods/hybrids the same way. But these days since the advent of the adjustable hosel sleeves in drivers and woods, companies have changed the way they measure loft. This video for which I gave you the link explains all of this very clearly. I hope this helps – watch the video, if you have other questions, please do come back and ask me and I will be glad to elaborate more to help you understand what it is you want to know.

  3. Big help and great information. Thanks very much… What part of the country do you live? Love to go through a fitting with you at some point down the road. Thanks JA

  4. Tom,

    I am the Golf Professional at Allegheny Country Club in Pittsburgh. I have played in a few PGA Championships and many other tournaments but I am always searching for the perfect clubs. I am 5’7″ and just recently I cut down all my clubs. Driver to 43 inches 5 iron is 37 inches. 3 hybrid 38 inches 2 hybrids 38.5 inches. I would love to hear your thoughts on club lengths… Thanks

    • JOHN:

      I’ve written and communicated a lot in my career, in books/articles/videos, to share everything I have learned in my long career about club design, performance and fitting technology with anyone who is interested in knowing the facts and truths. A big area has been with regard to club length because it is such an important fitting parameter for trying to achieve the highest level of shot consistency, path/angle of attack and release consistency, and to help a golfer get the most from his/her game.

      I am a very outspoken critic of the OEM’s trend over the past 30 yrs to steadily increase driver and wood lengths. Their move into 45-46″ drivers for men, 44.5″ drivers for women, 43.5″ 3 wood lengths, has most certainly been a very big reason why so many golfers can’t hit the driver or the woods as consistently as they could, even with their less than stellar swing characteristics. For the past many years, the average driver length on the PGA Tour has been 44.5″ – so what’s that say when the best players on the planet know they need to play a driver length that is the same as what OEM companies are forcing on women golfers and which is shorter than what they are selling off the rack to all men golfers?

      No question the vast majority of golfers would do better overnight with shorter length drivers and woods. And those who have taken the leap of faith to work with a good, experienced, independent custom clubmaker have found that out. Unfortunately that only comprises a very small percentage of golfers because the world of good clubmakers is so undermarketed, so underappreciated and so under utilized in the game thanks to the massive brainwashing image marketing campaigns of the OEMs.

      With regard to iron lengths, that is strictly a matter of finding the iron lengths that afford the most COMFORT OVER THE BALL and THROUGH THE BALL for each different golfer’s combination of height/arm length + posture/stance position. You don’t want to have the iron lengths force you into a stance/posture which is not well matched to your swing motion and athletic ability such that it would force you to stand too erect or bend or crouch down too much. COMFORT and being in a relaxed but proper stance/posture over the ball for your body and for your best swing plane is what rules iron length fitting.

      I will add that changing to 3/8″ increments between the irons is also something that has been proving to be a very good thing for many golfers. Not many have done this mainly because it is in the domain of the independent custom clubmaker to do this while the OEMs continue to pursue the old half inch increment standard. There are many golfers who may be comfortable over the ball with their 4,5 even 6 iron with half inch increments, but many of them do find when they get to the 8, 9, wedges, they have to either bend over more or crouch down more. And that’s not a good situation. So the change to 3/8″ increments has proven to be very good for allowing golfers to maintain a much more comfortable posture over the ball all the way down through the wedges, which then converts into a little better chance at shot consistency.

      For you, as a professional with a very strong game, on first thought a 43″ driver might be a tad on the short side but only for its potential effect on clubhead speed and distance. You undoubtedly have a later to very late release at your playing level. So that means you are a golfer who could get more clubhead speed with a longer length. At the same time, the reason the pros use 44.5″ drivers and not the 45-46″ driver length adopted as a “standard” by the OEMs is because even they with their superior ability can’t find the center of the face or the short grass as much with the longer length as with the shorter length.

      So for you, if the 43″ length still delivers decent, acceptable distance while offering a much better result for on center hits and fairways hit, then stay with it. For all players, there is this fine line between what length offers the best distance AND the best on center hit/accuracy results. You can’t play the game from the rough or the trees. And you most definitely are good enough to know where that length is for you and your game.

      Last one – you said you are 5’7. Depending on your posture and position through the ball, you may be a candidate for a driver and woods, hybrid as well, with a FLATTER LIE ANGLE. OEMs don’t make flat enough lies on drivers/woods/hybrids and we find there are more golfers today who need a flatter lie on their driver/woods/hybrids than what is offered. Please understand I am not here to sell you anything – I’m here to teach first and foremost. But this is why I developed driver/wood/hybrid models with a bendable hosel. And the clubmakers who work with our designs most certainly are now requesting us to bend flatter lies on the driver/wood/hybrid heads they order from us for their clubfitting work for golfers. I would tell you that for each such head we bend upright, there are 100 we bend flatter because the existing industry standard for driver, wood, hybrid lies are too upright for the vast majority of golfers out there.

      At any rate, thanks so much for your interest and I hope this has helped a little,

  5. It’s very interesting but quite confusing thinking of 15% shaft length and 85% loft that make an iron distance gaps. Actually I was thinking to covert one of my 8 iron into 9 iron by shortening the length only since I love the head shape of 8 iron much better than 9 iron. I was just roughly thinking of cutting off 1 inch without changing loft. Do you think this makes any sense? For your info, my handy cap is 9 and I hit 8 iron 140 yards and I expect the cut off 8 iron to be 125-130 yards (9 iron length).
    I would appreciate your comments.

  6. Tom,

    If you use a set of irons that are the same length and the head is the same weight, though you may lose some distance, wouldn’t the gapping between clubs still be consistent? and since many of us have a hard time hitting the lower irons, in theory, if all our clubs are the same length and we have a comfortable swing, it seems like it could lead to a more consistent swing. I guess what I am trying to ask is if you think the problem a lot of us have with lower irons is because of the longer clubs or the lower loft?

    Thanks, I always enjoy listening and reading your input on golf clubs.

    • Daniel:

      Thanks very much for YOUR interest in equipment, and we are always glad to help with the best information we can.

      Whether a conventional 4* change in loft between irons that would be made to the same length can offer consistent distance gaps depends on the golfer’s clubhead speed and their point of wrist-cock release on the downswing. Those are the two elements that combine to determine whether a golfer gets measurably different clubhead speeds from different club lengths. The later the release and the higher the clubhead speed with it, the more a golfer would see changes in clubhead speed and changes in distance from changes in club length.

      Hence for golfers with 5 iron clubhead speeds above 65mph and a later release, having all the irons the same length but still with a 4* loft change between clubs still causes the distance gaps to be compressed closer together.

      The reason pretty much ALL golfers cannot hit their lower number irons very well is because of the lower lofts combined with the fact the center of gravity in irons is not as low or as far back from the face as it is in a WOODHEAD or a HYBRID HEAD of the same loft. Low lofts are always harder to hit than higher lofts. Combine that with a CG position that in an iron is very close to the face and not all that low due to the height of a typical iron head and you have a situation where only those with the best and most consistent swing characteristics can hit the low loft long irons in their set.

      Thus the reason why smart golfers tend to have more hybrids in their bag to replace these naturally harder to hit irons with clubs that will hit the ball the same distance but be easier to hit with more consistency.


  7. Tom,

    I always enjoy your interviews on golfsmarter. I was hoping you might be able to answer a questions for me. Since, you said that the distance is 85% from the loft. Do you think a company like 1 iron golf could be on to something. If all irons were on length and had the same club head weight, and you would use the same swing. Couldn’t that be a beneficial thing? I know that the Tommy Armour ones didn’t take off, but they modeled them after a 6 iron, where 1 iron golf base it on your size, so a shorter golfer like me might have all the clubs the length of the 9 iron or pitching wedge. Since the 3 and 4 iron can be hard to hit, wouldn’t it make sense that the single length clubs would give the amateur golfer more confidence on the lower irons especially. It seems like you would be more consistent across the board once you had the swing down. and since the club heads weigh the same amount also, it would truly be the same exact swing motion.

    Thanks Tom! I love the service you are doing for the golfing community.

    • DANIEL:

      We’ve certainly looked at the concept of single length irons so we do know a fair bit about its potential strengths and weaknesses. But I think probably the most compelling history about this concept comes from back in the 90s when the former Tommy Armour Golf Company actually did market and sell a set they called the EQL. In the EQL, all woods were the same length, totalweight and swingweight as the 5 wood. In the irons, all irons were the same length, total weight and swingweight of the 6 iron.

      The EQL clubs debuted with great interest. At the time Armour was one of the more successful golf companies so the EQL introduction got a lot of press and interest. 6 months after the EQL clubs began to sell, Armour filed for bankruptcy protection because they experienced an 80% return rate on the clubs from people who did not like them at all. What happened was basically due to the 15% of distance that comes from the length of clubs.

      IN the woods, many who bought the EQL saw that they could not hit their 5 wood length driver as far as they hit their previous longer length driver. Certainly they hit the much shorter EQL driver straighter, but in golf, if a golfer buys a new driver and hits it shorter than his old one, 90% of them are NOT going to like that at all because distance is SO MUCH OF A PRIORITY for so many golfers. In the irons, many golfers found that the distances between clubs was compressed shorter than what they were used to, and they found they hit the 8, 9, PW longer than what they were used to. Both things pushed golfers over the line of acceptability and brought about the huge return rate and demand for a refund, which in turn put Armour under.

      Basically it comes down to this. For golfers with a slower swing speed and who have an early to midway unhinging of the wrist-cock angle on the downswing, a single length concept can be OK. Golfers with these swing characteristics will not really see much of a difference in distance loss from a shorter length driver, nor will they see much of a compression of distance gaps between irons or hitting the high number irons too far. This is because when you release the club early, longer length does not translate into higher clubhead speed at impact.

      but golfers with higher clubhead speeds who also have a midway to later to very late release WILL see differences in distance from different lenghts. So for these golfers, single length clubs can cause the experiences seen with the EQL sets. And when you mess with a golfer’s shot distances like that, most golfers will not like that at all.

      It is possible to engineer a single length set so it COULD perform properly a wider range of golfers. To do this chiefly would require the lofts of all the clubs to be staggered very different to each other than what is typical today for woods and irons to help overcome the effect on distance of length. But EQL did not do that and to my knowledge neither does the 1-Iron golf company. So as it stands now, pretty much only the golfers with slower speeds and earlier release can step into such a set and be OK.


  8. Great information about Golf Club Loft – Will The Real Loft Please Stand Up. It’s great to come across a blog every once in a while that isn’t the same out of date rehashed information. Although it took me time to read through all the comments, but I really enjoyed the article. Keep up the good work.

    • Much appreciated, and thank YOU for your interest in golf equipment performance and fitting. Because there is and has been so much bad information passed around about golf club performance, we do make a real effort to share what we know from all the experience we have in club design and the research we have done in clubfitting performance. Thanks much for being interested and letting us know it matters.
