If you have a full-size driver, a headcover made for 460cc will fit it. The Rules of Golf cap driver heads at 460cc, so a headcover built for that size will fit any legal full-size driver, whatever the brand. The exceptions are mini drivers and older, smaller heads. Beyond that, the opening and the height of the headcover decide how well it fits day to day.
Headcover sizing confuses people because most headcovers are labelled "fits 460cc" and nothing else. This guide explains what that number means, which drivers fall outside it, and the two measurements that matter more than the label.
What does 460cc mean on a driver?
460cc is the volume of the clubhead in cubic centimetres. It is also the largest driver head the Rules of Golf allow.
The R&A's Equipment Rules state that a clubhead "must not exceed 460 cubic centimetres", plus a manufacturing tolerance of 10cc. Manufacturers build their full-size drivers at or near that limit, because a larger head is more forgiving on off-centre strikes.
So when a headcover says it fits 460cc, it means it's built for the biggest driver head you can legally play. Anything the same size or slightly smaller will go inside it.
Will a 460cc headcover fit every driver?
It will fit every full-size driver, because no legal driver head can be bigger. It won't fit a mini driver or an older, smaller head well.
The R&A doesn't only limit volume. The same rule caps a wood's head at 127mm from heel to toe and 71.12mm from sole to crown. Every full-size driver from every brand works within those limits, which is why one headcover size can serve them all. A headcover built for a TaylorMade driver will fit a Ping, a Titleist or a Callaway of the same size.
Mini drivers are the main exception. They are a separate category and much smaller. TaylorMade's 300 Mini Driver, for example, has a 307cc head, about two-thirds the volume of a full-size driver. A 460cc headcover will go on, but loosely.
Older drivers are the other one. If yours dates from before heads grew to 460cc, check its size before you buy.
What measurements matter beyond 460cc?
The opening and the height matter more than the volume label, because they decide how a headcover goes on, how it stays on and how much of the club it protects.
The opening. This is where most fit problems start. Too narrow and you fight it onto the club on every tee. Too wide and the headcover slides off at the first bump, or lets the head move around inside. A good opening passes the head without forcing it and then sits snug around the neck. A structured shape helps, because the opening holds its size rather than stretching wider over a season.
The height. This decides how far the headcover reaches down the club. A short headcover covers the head and little else. A taller one reaches down over the neck and the top of the shaft, where the driver rubs against everything else at the top of the bag. Our guide to whether driver headcovers actually protect your club explains why that section picks up wear.
The shape. Two headcovers with the same measurements can still fit differently. A standard driver headcover bends at the neck. A barrel headcover sits straight and holds its form, which changes how it goes on and how it sits in the bag. We cover the trade-offs in our guide to barrel headcovers.
Most headcover brands don't publish these measurements. If you're buying online, look for the opening and the height on the product page. If they aren't listed, it's a fair question to ask before you buy.
I chose 460cc because it fits every legal driver, which covers almost any driver you'll see on a course. The only ones it won't fit are a few oversized novelty drivers that aren't legal for play, and hardly anyone uses those. The 30cm height is about how it sits in the bag. It's tall enough to reach down over the top of the shaft, where your short irons and wedges would otherwise knock against it.
How do you check your driver's size?
Check the clubhead first, then the manufacturer's specifications.
Many drivers have the head volume printed or engraved on the sole, usually as "460" or "460cc" near the loft marking. If yours does, you have your answer.
If it doesn't, look the model up on the manufacturer's website. Head volume is a standard line in the specification table, alongside loft, lie and length. For an older or second-hand driver, search the model name with "specs", and include the year if you know it, because brands reuse names.
If you can't find a figure, compare it by eye with a current full-size driver. A mini driver is clearly smaller, and its head sits between a driver and a fairway wood in size.
Will a driver headcover fit a fairway wood or hybrid?
It will go on, but it will be loose. Fairway woods and hybrids are much smaller than a 460cc driver.
TaylorMade's 2026 Qi4D fairway woods, as reported by GolfWRX, have heads between 175cc and 200cc depending on the model. That's less than half the volume of a full-size driver. A driver headcover on a fairway wood has too much room. The head moves around inside it and it comes off easily.
Fairway woods and hybrids need headcovers sized for them. The same principles apply: check the opening and the height, not just the label.
Does a headcover's fit change over time?
It can. How much depends on what holds the headcover's shape in the first place.
Knit headcovers change the most. The stretch that gets them over the head is the same stretch that loosens with use, so a knit headcover that fits snugly in spring can sit loose by the end of the season.
Structured headcovers change much less. A dense, high GSM weave holds its shape where lighter fabric goes slack, so the opening stays the same size. A deep pile such as sherpa fleece gives a headcover its body without relying on stretch, as long as the pile recovers rather than matting flat.
Wet weather plays a part too. A headcover that stays damp in the bag is more likely to lose its shape. Take it off the club and let it dry naturally after a wet round.
What happens if a headcover fits badly?
A loose headcover falls off and gets lost. A tight one wears at the seams and slows you down on the tee.
A loose fit is the more common problem, especially with knit headcovers that stretch over time. Forum threads such as "Headcover slides off, any ideas?" on GolfWRX are full of golfers trying elastic bands and leashes to keep one on. A headcover that fits properly in the first place doesn't need either.
A tight fit is rarer but costs more over time. Forcing a headcover over the head every time strains the stitching at the rim and can drag a rough lining across the crown. If you have to twist and pull, it's too small.
Frequently asked questions
Does a 460cc headcover fit a 440cc driver?
Yes. A 440cc head is slightly smaller than the 460cc maximum, so it will sit a little roomier but still fit well. The opening matters more than the 20cc difference.
Do driver headcovers fit all brands?
A headcover sized for 460cc fits full-size drivers from any brand, because they all work within the same R&A limits on volume and head dimensions. Mini drivers are the exception, whatever the brand.
Does an adjustable hosel affect headcover fit?
Most adjustable hosels add a little bulk at the neck. A headcover with a reasonable opening and enough height to reach past the hosel will sit over it without trouble.
Finding a headcover that fits your driver
Start with your driver's head size, then check the opening and height of any headcover you're considering. If the brand doesn't list them, ask.
All three Sacred Greens driver headcovers are built for drivers up to 460cc. Each is 30cm tall with a 14cm opening measured edge to edge, barrel-shaped and lined in microfiber velvet. The Bothy is sherpa fleece, The Greenside is a woven green and white houndstooth, and The Heritage is a tartan woven through the fabric. If one doesn't fit the way you expected, you can return it unused within 30 days, and we cover the return postage.
