Black Cowhide Pin Buckle Belt for Men, 3.8cm Wide £19.99 · Free UK delivery Shop Your belt size is your trouser waist size plus two inches. A 34 inch waist takes a 36 inch belt.
How do you measure your belt size?
You measure your belt size from the waist size of trousers that fit you well. This is often called the plus two method. The extra length lets the belt pass through the loops and the buckle.
Read the waist size on the label of your well fitting trousers. If there is no label, measure around your waist at the point where the trousers sit. Use a soft tape and keep it level. Do not pull it tight.
What does a men’s belt size chart look like?
A belt size chart converts trouser waist to belt size. Each row below applies the plus two method. Centimetres are rounded to the nearest centimetre.
| Trouser waist | Belt size | Belt size in cm |
|---|---|---|
| 30 inch | 32 inch | 81cm |
| 32 inch | 34 inch | 86cm |
| 34 inch | 36 inch | 91cm |
| 36 inch | 38 inch | 97cm |
| 38 inch | 40 inch | 102cm |
| 40 inch | 42 inch | 107cm |
Compare the chart with a belt you already own before you order.
How do you measure a belt you already own?
You measure a belt you own from the hole you use most to where the buckle begins. Lay the belt flat on a table first. The most used hole is usually the most worn one.
Run the tape from the centre of that hole along the strap. Stop at the point where the buckle starts. Do not measure into the buckle.
The figure in inches is your belt size. Compare it with the result from your trouser waist. If the two numbers are close you have the right size.
What if your measurement falls between sizes?
A measurement that falls between sizes should be rounded up to the next whole inch. A 37 and a half inch measurement becomes a 38 inch belt.
Rounding up is the safer choice. A belt that is too short may not close at all.
What size are LuxuryTrex belts?
LuxuryTrex belts are listed in lengths from 105cm to 130cm. The supplier does not state which trouser waist each length fits.
| Belt | Listed length | Width | Buckle |
|---|---|---|---|
| Black automatic buckle belt | 110cm to 130cm | Not stated | Square alloy automatic buckle |
| Black pin buckle belt | 105cm to 125cm | 3.8cm | Alloy pin buckle |
| Black split leather belt | 110cm | Not stated | Alloy automatic buckle, gunmetal finish |
| Brown pin buckle belt | 105cm to 125cm | 2cm to 4cm band | Alloy pin buckle |
The listed lengths run longer than most belt sizes in the chart. To compare like with like, measure a belt you own from the buckle end to the tip. Compare that full length with each listed length. A listed length close to that figure is a sound starting point. The supplier does not confirm where its length is measured from.

What is the difference between a pin buckle and an automatic buckle?
A pin buckle fastens through holes in the strap. The automatic buckle is named but not explained in the listings.
The black and brown pin buckle belts both use a pin. Their fit changes in steps set by the hole spacing.
An automatic buckle is the supplier’s name for the fastening on the other two belts. The listings call one a square alloy automatic buckle. An automatic buckle usually grips a plain strap with no holes. These listings do not confirm that mechanism.
How wide should a belt be?
A belt must be narrower than the gap inside your trouser loops. Measure that gap with a ruler before you buy. Then compare it with the width in the table above.
The black pin buckle belt is the one belt here with an exact width, at 3.8cm. If the gap is wider than that figure the belt will pass through.
The brown pin buckle belt is given only as a band between 2cm and 4cm. The two automatic buckle belts state no width. If your loops are narrow, pick the belt with the known width.
How should a belt fit when it is fastened?
A belt fits when it closes on a hole near the middle and sits flat around the waist. The buckle should rest at the centre of your trouser fly.
Check three things when you put it on:
- The buckle closes on a middle hole with holes spare either side.
- The tip of the strap reaches the first trouser loop past the buckle.
- The strap lies flat without folding or bunching at the loops.
A tip that ends before the first loop means the belt is short. A tip that runs past the second loop means it is long.
What if a LuxuryTrex belt is too long?
The listings do not say the straps can be cut or the buckles removed. Plan to buy the right length.
If your belt is a little long, fasten it on a tighter hole. The spare strap then tucks into the first loop.
Which belt should you choose?
Choose by the buckle and the colour you wear most.
- For a black belt with a square automatic buckle in the longest lengths, choose the black automatic buckle belt.
- For a black belt with a pin buckle and a stated width, choose the black pin buckle belt.
- For a split leather strap with a gunmetal buckle, choose the black split leather belt.
- For a brown belt at £17.99, choose the brown pin buckle belt.

Questions answered
Do belt sizes run the same across brands? +
No, brands do not all measure a belt the same way. Check the size chart on each listing against your own measurement.
Are belt sizes in inches or centimetres? +
Both. The chart above gives each size in inches and centimetres. LuxuryTrex belts are listed in centimetres.
Should I buy a belt by my jeans size or my suit trouser size? +
Use the waist size of the trousers you will wear the belt with most. If the labels differ, measure a belt you already wear with them.
Can I wear a belt that is one size too big? +
Yes, if the tip still stops between the first and second trouser loops. A belt that only closes on its tightest hole is too big.
