How Does Vintage Golf Clothing Fit? A Practical Size Guide
Share
A medium has never meant exactly one thing. That is particularly true in vintage golf clothing.
An 80s Greg Norman polo labelled medium can fit more like a modern large or XL. A TaylorMade windbreaker from a similar period may be boxy but otherwise fairly true to size. Two pieces of vintage knitwear carrying the same label can measure completely differently based on style and fabrics!
That is why we do not rely on the size printed inside a piece of clothing - its an indicator only.
Every top at The Rules of Golf is measured laid flat. We record the width from armpit to armpit and the length from the back of the collar to the bottom hem. We then use those measurements, the type of clothing and our experience of how it compares with modern clothing to provide a recommended size.
The label remains part of the clothing's story. The measurements tell you how it will actually fit!
Why the recommended size can differ from the label
Our recommended size is based primarily on the actual chest measurement, but it is not generated from the tape measure alone.
We also consider:
- the type of clothing and style
- whether it was designed to be layered
- the brand and likely period
- the overall cut and proportions
- the weight and movement of the fabric
- how comparable pieces fit against modern clothing
This is why a labelled medium may be recommended as a large, or why a wide vintage windbreaker may remain a recommended medium because the extra room is part of its intended shape.
The recommendation is practical guidance based on the individual garment. It does not replace comparing the listed measurements with something you already own.
Our vintage golf clothing size guide
The figures below are the flat pit-to-pit measurements we use as the starting point for our recommended sizing.
Do not double these figures when using the table. Double them only when you want an approximate full garment circumference.
Polos, mock necks and T-shirts
| Flat pit-to-pit measurement | Recommended size |
|---|---|
| Under 19 inches | Small |
| 19–21 inches | Medium |
| 21.5–23 inches | Large |
| 23.5 inches and above | XL |
Polos sit relatively close to the body, so the thresholds are lower than they are for jackets and jumpers. Vintage examples can still have much fuller sleeves, wider bodies and firmer collars than modern performance shirts.

Vests and gilets
| Flat pit-to-pit measurement | Recommended size |
|---|---|
| Under 19 inches | Small |
| 19–22 inches | Medium |
| 22.5–25 inches | Large |
| 25.1 inches and above | XL |
A knitted vest needs room for a polo underneath without pulling across the chest. Wind vests and insulated gilets are usually designed with more space through the body, placing them between polos and full outerwear in our sizing approach.

Windbreakers, jackets, fleeces and jumpers
| Flat pit-to-pit measurement | Recommended size |
|---|---|
| Under 20.5 inches | Small |
| 21–23 inches | Medium |
| 23.1–26 inches | Large |
| 26.1 inches and above | XL |
These garments were made with layering and movement in mind, so their chest measurements are naturally larger. A 24-inch windbreaker should not automatically be treated in the same way as a 24-inch polo.
Where a measurement falls between two bands, we look at the overall cut, length, fabric and intended shape before assigning the recommendation.

How vintage golf polos fit
Polos produce some of the biggest differences between label size and modern fit.
Many shirts from the 1980s and early 1990s have fuller bodies, longer sleeves and more room beneath the arms. A medium from that period can comfortably measure like a modern large or XL.
This is particularly common across early Greg Norman, Ashworth and Nike Golf polos. Substantial embroidery, stitched patterns, heavier fabrics and older logo treatments can all be clues that a shirt belongs to a fuller-cut period, although none should be treated as a sizing rule on its own.
By the early 2000s, many golf polos had moved towards lighter performance fabrics and sizing that feels more familiar today.
How vintage golf windbreakers and jackets fit
Golf outerwear was made to move through a swing and sit over another layer. That naturally created wider bodies, generous sleeves and boxier shapes.
Windbreakers from the 1980s and early 1990s are often particularly broad. That does not always mean you should size down.
A roomy body, dropped shoulder or wide raglan sleeve may be central to how the jacket is meant to look. Removing all of that room can turn a strong vintage shape into a jacket that simply feels too short or restrictive.
Compare both chest and length. An older windbreaker can be very wide without being especially long.
How vintage jumpers and knitwear fit
Knitwear is the least consistent category.
Washing, storage, fabric composition and previous wear can all change the shape. A jumper may have retained its width but lost length, or become tighter through the body while the sleeves remain generous.
Two jumpers from the same brand, period and labelled size can therefore fit differently.
This is where the listed measurement matters most. Compare both the chest and back length rather than using the label or brand as the deciding factor.
How vintage golf trousers and shorts fit
For trousers and shorts, we normally use the stated waist size as the starting point.
Vintage golf bottoms can feel slightly smaller through the waist than the equivalent modern size, although they are generally more predictable than polos. Leg lengths also tend to be generous, particularly across traditional golf trousers.
Some shorts have a noticeably different front and back length because of the rise and cut. Check the full description rather than judging the length from the front photograph alone.

How vintage Nike Golf fits
Vintage Nike Golf sizing changes considerably across the years.
Some of the earliest polos have the biggest proportions we see. Patterned shirts, heavily stitched designs and early Tiger Woods or Yin Yang-era pieces can come up one or two modern sizes larger than the label suggests.
The windbreakers are more manageable. They are often boxy, but generally not as dramatically oversized as the earliest polos.
As Nike moved into the early 2000s, its sizing became more consistent with modern sportswear. Lighter Dri-FIT polos and performance layers are usually less surprising than substantial earlier cotton or woven shirts.

How Greg Norman and Ashworth fit
Greg Norman is one of the clearest examples of why the label cannot be trusted on its own.
An 80s or 90s Greg Norman polo labelled medium can easily fit like a modern large or XL. Across the pieces we handle, the difference is often closer to two sizes than one.
Greg Norman windbreakers can also be generous, although the intended outerwear shape accounts for some of that space.
Ashworth follows a similar pattern. Its vintage polos can be exceptionally full through the chest and sleeves, while its windbreakers tend to be slightly more consistent.
How TaylorMade, PING and adidas fit
TaylorMade is generally fairly true to size, although older pieces can be boxier than their modern equivalents. Someone who wears a modern large or XL can often still take a labelled large TaylorMade layer.
PING follows the broader pattern of the period: 80s and 90s polos tend to run larger, while windbreakers are roomy but more predictable.
Vintage adidas Golf outerwear is often fairly true to size. Its older polos can run bigger, particularly pieces carrying prominent Golf wording, traditional three-stripe treatments or substantial early embroidery.
How Mizuno, FootJoy, Titleist and Callaway fit
Mizuno is one of the more consistent brands we handle and is often relatively true to size across different garment types.
FootJoy windbreakers tend to have a boxy, generous cut, but rarely reach the extreme proportions found in some early Greg Norman pieces.
Titleist and Callaway are much less predictable. Both used a wide range of fabrics and suppliers, and some older garments have clearly changed shape over time.
Callaway’s California pieces can be particularly inconsistent. Fabric and shrinkage can matter as much as the label, making the actual measurements essential.
Measurements we always re-check
Our catalogue process flags measurements that look unusual for the garment and stated size. Examples include:
- a labelled large or XL with a chest under 20 inches
- an XL windbreaker with a back length below 26 inches
- a garment whose length is unusually short relative to its width
These do not automatically mean a measurement is wrong. A genuinely cropped or exceptionally boxy piece may produce an unusual result. They do mean we stop and measure it again before relying on the number.
Should you size down in vintage golf clothing?
Sometimes, but not automatically.
Size down when the measurements show that the garment is substantially larger than something you already wear and you want a neater modern fit.
Do not size down purely because the description says “boxy” or because the label appears large. You may lose the sleeve length, body length and movement that made the original shape work.
The safest approach is always the same: measure a comparable garment you already own and choose the vintage piece whose dimensions are closest to it.
How to measure pit to pit
“Pit to pit” is the flat measurement across the chest of a garment.
- Choose a polo, jumper or jacket that already fits you well.
- Lay it flat on a table or the floor without stretching the fabric.
- Measure in a straight line from the bottom of one armpit seam to the other.
- Compare that figure with the pit-to-pit measurement shown in our product listing.
An item measuring 22 inches pit to pit has an approximate 44-inch chest circumference when doubled. However, that does not mean it will fit exactly like every other 44-inch clothing.
The cut still matters. A boxy windbreaker, fitted performance polo and thick knitted jumper can all share the same chest width but sit very differently on the body.
How we measure garment length
For polos, jumpers, fleeces, jackets and other tops, we measure down the back from the top of the collar to the bottom hem.
Some are deliberately longer at the back than the front. This is particularly common across certain polos. Where the difference is material, we note it in the description.
Vintage golf sizing FAQs
What does pit to pit mean?
Pit to pit is the flat width across a garment from one armpit seam to the other. Double it for an approximate full garment chest circumference.
Is a vintage medium the same as a modern medium?
Not necessarily. Some 80s and 90s golf polos labelled medium fit like modern large or XL garments. Later performance clothing is often closer to current sizing.
Why is the recommended size different from the label?
Our recommendation is based on the garment’s actual measurements, cut, category and comparison with modern clothing. The label is recorded, but it does not overrule what the tape measure shows.
Do vintage golf windbreakers run big?
Many do, because they were designed for layering and unrestricted movement. They can be wider and boxier than modern technical jackets without necessarily being longer.
Are vintage Nike Golf polos oversized?
Earlier Nike Golf polos can run one or two modern sizes larger, particularly substantial patterned, stitched and early Tiger-era designs. Early-2000s performance polos are usually more consistent with modern sizing.
What is the best way to choose my size?
Take a similar garment that already fits you, lay it flat and compare its pit-to-pit and back-length measurements with the individual product listing.
Measure the piece, not the expectation
Vintage sizing is inconsistent, but it does not need to be a gamble.
The label tells you what the manufacturer called it decades ago. The chest, length, cut and fabric tell you how it fits today.
Start with something you already own. Measure it in the same way. Then choose the vintage piece whose actual dimensions and shape work for you.
That is a much better guide than the letter stitched into the collar.
