Impact of Loft on Iron Distance: The Gapping Guide
How to ensure you don't have 'distance holes' in your bag.
In modern golf, a '7-iron' isn't what it used to be. One brand's 7-iron might have 28 degrees of loft, while another's has 34 degrees. This 'loft creeping' has made it difficult for golfers to know how far their clubs should actually go. Understanding the relationship between loft and distance is the key to 'Gapping'—ensuring that you have a consistent 10-15 yard difference between every club in your bag.
The 1 Degree = 3 Yards Rule
As a general rule of thumb, for a mid-speed amateur, changing the loft by 1 degree results in a change of approximately 3 yards in carry distance. If your 7-iron is 30 degrees and your 8-iron is 34 degrees, you should expect about a 12-yard gap. If the gap is 20 yards or only 5 yards, your lofts need to be adjusted by a club builder.
Launch Angle vs. Static Loft
Loft isn't the only thing that determines height. Your 'Dynamic Loft'—the actual loft of the club at impact—is affected by how you swing. If you 'de-loft' the club by leaning the shaft forward at impact, you will hit it further but lower. Our distance calculator helps you estimate these changes based on your swing characteristics.
The Danger of 'Game Improvement' Irons
Modern game-improvement irons use very strong lofts to help people hit the ball further. While a 170-yard 7-iron sounds great, it often leads to a massive gap at the bottom of the bag. You might find you have a 30-yard gap between your Pitching Wedge and your first Sand Wedge. Proper gapping requires adding 'Gap Wedges' to cover these specialized distances.
Checking and Adjusting Your Lofts
Forged irons can actually bend over time from hitting off hard mats or through regular play. It's a good practice to have your lofts and lies checked once a year by a pro shop. A simple 1-degree adjustment can often fix a club that you've 'lost confidence' in because it was going the wrong distance.
FAQ
What is the standard loft for a 7-iron?
There is no 'standard' anymore. 'Tour' irons are usually 34-35 degrees. 'Game Improvement' irons are 28-30 degrees. Always check the manufacturer's spec sheet for your specific model.
Can I change my club's loft myself?
No. It requires a specialized 'Loft and Lie' machine and a significant amount of force. Attempting to bend clubs without the proper equipment can snap the hosel or damage the plating.
Does changing loft affect the 'bounce' of the club?
Yes. Adding 1 degree of loft increases the bounce by 1 degree. Subtracting 1 degree of loft (strengthening it) reduces the bounce. This is particularly important for wedges played from soft or hard turf.
