The Difference Between the 44mm vs 40mm

Apple Watch Series 6 44mm vs 40mm

As you can see from the table above, the 40mm and 44mm have the same features and appearance. Each of these two comes with a 32GB storage capacity and will also track your heart rate, calories, sleep, stress, blood oxygen, and steps.

Each of these two also has an inbuilt GPS that allows you to track your outdoor routes and locations without carrying your iPhone along.

The design is also the same, both sizes come in three materials, aluminum, stainless steel and titanium case materials, while the aluminum unit has an Ion-X glass screen, the stainless steel and titanium units have a sapphire glass screen.

  1. The 44mm has a bigger display size than the 40mm unit. While the 40mm unit has a 1.57 inches display size, the 44mm unit has a 1.78 inches display size that allows you to see more at a glance.
  2. The 40mm being smaller is a more compact smartwatch than the 44mm unit. Although, both sizes are still very compact. In fact two of the most compact smartwatches.
  3. The prices are also different. The 40mm unit being smaller is cheaper than the 44mm unit.
  4. Although Apple didn’t specify the battery capacity of the Watch 6, the 44mm unit most likely has a bigger battery capacity than the 40mm unit. However, since the 44mm unit has a larger display size, it has about the same 18hrs battery life as the 40mm unit.

Although the 44mm is bigger than the 40mm, both smartwatches are still very compact. The right choice for you depends on your wrist size which is what is intended here in the first place. The difference in size is to give consumers the option to choose their preferred size based on the wrist size of the individual.
