Apple Watch Series 10 Band Sizes: What’s New?

The Series 10 introduces new case sizes:

  • 46mm (replacing 45mm in previous standard models)
  • 42mm (replacing 41mm for smaller wrists)

This update sparked confusion among users: “Will my old Apple Watch bands still fit?” Fortunately, Apple retained backwards compatibility for most previous sizes.

Here’s a quick look at how the new sizes map to older models:

  • 46mm Series 10 fits bands made for: 49mm (Ultra), 45mm, 44mm, and 42mm
  • 42mm Series 10 fits bands made for: 41mm, 40mm, and 38mm

So, while the sizing labels changed, most existing bands will still fit!


Are Series 10 Apple Watch Bands Different?

No, Apple Watch Series 10 bands are not technically different. The lugs and locking system are still the same, which means your old bands will fit — as long as they match the corresponding size range.

The only difference is in how Apple labels the case size. Instead of using 41mm and 45mm, Series 10 uses 42mm and 46mm. But the connection mechanism has not changed.

So if you previously owned an Apple Watch Series 9, Series 8, or even Series 6 — your band collection is still usable with the right case size.


Series 10 46mm Band Compatibility

If you own the 46mm Apple Watch Series 10, your band compatibility is quite broad. The following sizes will fit:

  • 49mm bands – Apple Watch Ultra & Ultra 2
  • 45mm bands – Apple Watch Series 7, 8, 9
  • 44mm bands – Series 6, 5, 4, SE (1st & 2nd Gen)
  • 42mm bands – Series 3, 2, 1

👉 Tip: Even though 46mm technically replaces 45mm, the band lug system remains identical. So if a band fits a 45mm case, it’ll also fit the 46mm.

Series 10 42mm Band Compatibility

For those who opted for the 42mm Apple Watch Series 10, you’re still covered when it comes to backwards compatibility.

It supports bands originally made for:

  • 41mm bands – Apple Watch Series 7, 8, 9
  • 40mm bands – Series 4, 5, 6, SE
  • 38mm bands – Series 3, 2, 1

Important Note: Some wider bands for 44mm or 45mm may appear too large on a 42mm case. Always match width for aesthetics.
