What's my size?
Our bands come in two sizes: Small and Large. The size you need depends on the case size of your Apple Watch (the size of the watch itself), not on the size of your wrist. Every band can be adjusted to fit your wrist.
Step 1 – Find your case size
Choose one of these ways:
- On the back of your watch: turn your watch over. The case size (for example "41mm" or "45mm") is engraved on the back.
- On your iPhone: open the Watch app → General → About. You'll see your model and case size.
Step 2 – Match your size
| Your Apple Watch | Case sizes | Choose |
|---|---|---|
| Series 1, 2, 3 | 38mm | Small |
| Series 1, 2, 3 | 42mm | Large |
| Series 4, 5, 6 & SE (all generations) | 40mm | Small |
| Series 4, 5, 6 & SE (all generations) | 44mm | Large |
| Series 7, 8, 9 | 41mm | Small |
| Series 7, 8, 9 | 45mm | Large |
| Series 10 & later | 42mm | Small |
| Series 10 & later | 46mm | Large |
| Ultra (all generations) | 49mm | Large |
Good to know about 42mm: a 42mm watch from Series 10 or later takes Small. A 42mm watch from Series 1, 2 or 3 takes Large. Not sure which Series you have? Check the Watch app on your iPhone (General → About).
