Determine Your Apple Watch Screen Size

When buying Apple Watch bands, you just need to know if you own the small or large screen version of the Apple Watch. Bands are then split into the two types depending on the Series. Small Screens are either 38mm or 40mm and large screens are either 42mm or 44mm. 

Usually the series and screen size of your Apple Watch is printed on the back of your Apple Watch.

Small Screens

Series 0,1,2,3 are 38mm.

Series 4,5,6,SE are 40mm.

--> When buying, choose “38/40mm”

Large Screens

Series 0,1,2,3 are 42mm.

Series 4,5,6,SE are 44mm.

--> When buying, choose “42/44mm”

Purchasing a Case or Screen Protector

If you are purchasing an Apple Watch Screen Protector or an Apple Watch Case, you must know the exact size of your screen or it won’t fit. So you will need to choose one of 38mm, 40mm, 42mm or 44mm.

Determine Your Wrist Size and Check the Band Sizes

Band sizing information is displayed in the Additional Information section on each product page for all our watch bands. Just click on the words ‘Additional Information’ at the top of the product’s Description to see full wrist sizing information applicable to that band. After that, the only thing you will need to do is measure your wrist to check the band will fit.

If you have a paper or plastic measuring tape, just wrap it around your wrist to see what your wrist circumference is. If you don’t have one of these, you can cut a strip of paper off the long edge of an A4 sheet, wrap it around your wrist, make a mark where it joins and then take it off and measure how long it was with a ruler.

Adults will typically have a wrist circumference around the 14.5cm – 21cm mark.
