Men’s shirt size chart
Button-up or formal shirts use international letters or collar sizes which are based on neck measurements. The fit of the shirt can also be indicated in the description field (e.g. regular fit, slim fit, skinny fit).
NoteInternational sizing isn't standardized, so sizes can differ across countries or regions. If you're not sure about an item's size, exact measurements can help.

How to measure collar size?
- Take flexible measuring tape for sewing or tailoring
- Measure around your neck at the level of your Adam’s apple.
Leave a little slack when measuring so the shirt isn’t too tight around the neck. You should be able to comfortably fit two fingers between your neck and the measuring tape.
