A 43cm shirt is measured by collar circumference, not chest or body size. In Australian sizing, 43cm typically falls in the XL bracket, suited to broader necks and larger builds.
It's one size up from 42cm and one down from 44cm. The difference between each size is small (1cm at the collar), but it's enough to change how a shirt sits at the neck when buttoned.
Some shoppers know their size in inches or letters rather than centimetres, particularly if they've bought shirts overseas. Here's how 43cm lines up:
| Collar (cm) | Collar (inches) | Letter size |
|---|---|---|
| 43cm | 16.9in (sold as 17) | XL |
Note: brands round to the nearest half inch, so a 43cm collar is sold as a 17-inch shirt in markets that use inch sizing.
| 42cm | 43cm | 44cm | |
|---|---|---|---|
| Letter size | L | XL | XL |
| Best for | Slightly narrower necks than 43cm | Broader necks, medium-large builds | Broader still, or preferring more room at the collar |
If you're between 42cm and 43cm, size up for a tie-friendly fit or down for a closer, more casual collar. Between 43cm and 44cm, both sit in the XL bracket, the difference is 1cm of room, not a fit-category change.
43cm sits one size above 42cm and one below 44cm, all close to the XL bracket. The step from 42 to 43 moves you from L into XL, while 43 to 44 stays within XL with slightly more room at the collar.
Typically, a size 43 shirt fits chest dimensions around 116-120 cm.
Measure your neck circumference where the collar sits comfortably using a soft tape, allowing slight room for comfort.
Generally, 43 cm shirts suit medium to larger builds; slim builds would likely prefer smaller neck sizes for a better fit.
It is larger than 42 cm size and suitable for those needing a more generous fit around the neck and chest.
A 43cm collar converts to 16.9 inches, which most brands round up and sell as a 17-inch collar. If you're used to shopping in inches, look for 17 on the label.
