Everything you need to choose the right wrist size and screen connection for your smartwatch band.
Which smartwatch do you have?
What is your wrist circumference?
| Size | Wrist circumference | Variant name |
|---|---|---|
| S | 14.5 – 16 cm (5.7–6.3 in) | 14.5 - 16 cm (S) |
| M | 16 – 17.5 cm (6.3–6.9 in) | 16 - 17.5 cm (M) |
| L | 17.5 – 19 cm (6.9–7.5 in) | 17.5 - 19 cm (L) |
Which Apple Watch size do you have?
Check your Apple Watch case size carefully before selecting your variant.
1. Back of your watch
Check the back of your watch for the case size, e.g. 45 mm.
2. Or via the Watch app
Open the Watch app on your iPhone → General → About → Model details.
What is your wrist circumference?
| Size | Wrist circumference | Screen connection |
|---|---|---|
| S | 14.5 – 16 cm (5.7–6.3 in) | 20 mm or 22 mm |
| L | 16.5 – 18 cm (6.5–7.1 in) | 20 mm or 22 mm |
How to find your case size
1. Back of your watch
Turn your watch over and find the case size in mm. Only a model number (e.g. SM-R940)? See the tip below.
2. Or via the app
Open Galaxy Wearable → Watch settings → About watch.
Does this band fit other brands too?
Our bands use the standard Quick Release connection (20 mm or 22 mm) — the same one Samsung uses. Many other watches, including various Garmin models, use this exact connection, so our bands often fit those as well. Always check that your model uses a Quick Release pin connector in 20 mm or 22 mm before ordering.

How to measure your wrist
Measure your wrist where you normally wear your watch.
Using a tape measure
Wrap the tape around your wrist, just above the wrist bone. Not too tight, not too loose — one finger should still fit underneath.
No tape measure?
Wrap a charging cable or strip of paper around your wrist, mark where it ends, lay it flat and measure with a ruler. Measure to one decimal, e.g. 15.7 cm.
