Find your fit
Choose a category below to see measuring advice and international size conversions.
Start with the product’s own size guide. Fit can vary between brands, styles and fabrics. Where a brand has supplied one, you’ll find a “Size Guide” link just above the size selector on the product page.
These general guides are approximate. Check the product description and brand’s guide before choosing your size.
Shoes, boots & footwearUK sizes and choosing the right conversion
All shoes and boots are shown in UK shoe sizes. International conversions can differ between brands, so use the brand’s size guide or the information on the product page rather than a general conversion chart.
Hats & capsHead measurements and hat size conversions

On smaller screens, swipe across the table to see all columns.
| Size | Head (cm) | Head (inches) | UK | US / Canada |
|---|---|---|---|---|
| Small | 55 | 21½ | 6¾ | 6⅞ |
| Medium | 57 | 22¼ | 7 | 7⅛ |
| Large | 59 | 23 | 7¼ | 7⅜ |
| XL | 61 | 23⅞ | 7½ | 7⅝ |
How to measure your head
- Wrap a soft tape measure around your head where the hat will sit: approximately 1cm above your ears, slightly lower at the back.
- Keep the tape comfortable, rather than tight. Most hat headbands have little or no stretch.
- Read the circumference where the tape meets. If you’re between sizes, choose the larger size.
No tape measure? Use string, mark where it meets, then measure it against a ruler.
Some brands and styles may differ.

How to measure your chest
- Wear a thin T-shirt or measure bare-chested. Stand naturally with your arms relaxed.
- Wrap a soft tape measure around the fullest part of your chest, just under your armpits and across your shoulder blades.
- Keep it level, snug but not tight. Breathe normally and record the measurement in inches or centimetres. Measure again to check.
Some brands have a slimmer mod fit. Check the brand’s guide and product description if you prefer more room.
Comparing with a jacket you own
Fasten a well-fitting jacket and lay it flat. Measure across the front from armpit to armpit, then double that measurement. For example, 19 inches across gives a garment chest circumference of 38 inches. This is the garment measurement, not your body chest size: it includes room to move, so compare it only with garment measurements supplied for the product.

| 18–18½ | 46–47 | XXL |
| 19–19½ | 48–49 | XXXL |
To measure your collar, place the tape around the fullest part of your neck. Allow two fingers between the tape and your neck for comfort, then round up to the next half inch. Exact fits vary by brand.

How to measure your waist
- Check the brand’s guide for where to measure: the natural waist or where the waistband sits.
- Stand relaxed and wrap the tape around that point. Keep it snug but not tight, allowing a finger under the tape.
- Record the measurement in inches and compare it with the product’s size guide.
You can also compare with trousers you own. Fasten them, lay them flat and measure the waistband without stretching it. Double the flat width to get the garment’s waist circumference.
On smaller screens, swipe across the table to see all columns.
| Label | Inches | Centimetres |
|---|---|---|
| Short | 30 | 76 |
| Regular | 32 | 81 |
| Long | 34 | 86 |
| Extra long | 36 | 91 |
Most styles are stocked in up to three leg lengths. Extra long is included here as a conversion reference. Some brands use 29, 31 and 33 inches for short, regular and long; check the product’s description.
How to measure your inside leg
- Lay a pair of trousers with your preferred leg length flat.
- Measure along the inside leg from the crotch seam to the hem.
- Alternatively, have someone measure down your inner leg from the crotch to where you want the hem to finish.
Men’s suits & tailoringJacket sizes, lengths and suit size conversions
A UK jacket size such as 40 refers to the chest size in inches. European sizes use a different numbering system: for example, UK 40 is approximately EU 50. S, R and L refer to jacket length, where available.
Suit trousers are often around 6 inches smaller at the waist than the jacket chest size: for example, a UK 40 jacket with 34-inch waist trousers. Check the actual sizes supplied for the suit.

How to measure
Use a soft tape measure over close-fitting clothing or underwear. Keep it level and snug without pulling it tight. A mirror or someone to help can make this easier.
- Bust: with arms relaxed, measure around the fullest part of your bust.
- Waist: measure around your natural waist, the narrowest part of your torso, usually just above your belly button.
- Hips: stand with feet together and measure around the fullest part of your hips and seat.
- Compare all three measurements with the brand’s size guide, or use the general body measurements above as a starting point.
