Apple Watch Strap & Size Guide: Change, Replace, Choose

Whether you’re upgrading your style or replacing a worn strap, finding the right Apple Watch band and understanding how sizes work is essential. This guide covers Apple Watch sizes, how to change your strap safely, and the best strap types for every lifestyle, from workouts to weddings.

1. Understanding Apple Watch Sizes

Apple Watch models come in different case sizes:

• Small cases: 38mm, 40mm, 41mm

• Large cases: 42mm, 44mm, 45mm

• Apple Watch Ultra: 49mm

Important:

• Bands designed for 38/40/41mm cases are interchangeable.

• Bands for 42/44/45/49mm cases also work interchangeably.

Tip: Want a snug fit? Use a soft measuring tape (or wrap a strip of paper around your wrist) to find your wrist size in millimetres. You can also use Apple’s official band size guide to match your wrist to the correct S/M or M/L band.

2. How to Measure & Select the Right Band

Steps to measure:

1. Measure your wrist circumference with a flexible tape.

2. Match to Apple’s sizing:

   • S/M: Small to medium wrists

   • M/L: Medium to large wrists

   • XL: For larger wrists (less common)

3. Double-check size in the Apple Watch app:
   Go to My Watch > Band Size for recommendations based on your watch and usage.
