What Size Is Samsung Galaxy Watch 7
The Galaxy Watch 7 comes in two sizes: 40mm and 44mm. The 44mm offers a larger display and significantly longer battery life, while the 40mm is lighter and better suited for smaller wrists.

|---|---|---|
| Case Dimensions | 40.4 x 40.4 x 9.7mm | 44.4 x 44.4 x 9.7mm |
| Display Size | 1.3 inches | 1.5 inches |
| Weight | ~28g | ~33g |
| Battery | 300mAh | 425mAh |

How to Choose
Measure your wrist circumference (wrap tape where watch sits):
| Wrist Size | Recommended |
|---|---|
| Under 140mm (5.5") | 40mm |
| 140-165mm (5.5-6.5") | 40mm |
| 165-185mm (6.5-7.3") | Either (preference) |
| Over 185mm (7.3"+) | 44mm |
40mm vs 44mm
Choose 40mm if:
- You have a small to medium wrist
- You prefer lighter, subtler watches
- You'll wear it during sleep (lighter weight)
- You want the most comfortable fit
Choose 44mm if:
- You have a larger wrist
- You prioritize battery life (25-30% longer)
- You want maximum display visibility
- You prefer a bold watch presence
Battery Life Matters
The 44mm has 42% larger battery but only 15% larger screen. This gives it a significant net advantage of 25-30% longer battery life. If you're torn between sizes and battery matters, go larger.
Band Compatibility
Both sizes use 20mm bands — all Galaxy Watch 7 bands fit either size, and previous Samsung 20mm bands are compatible.
