Size Specifications

How to Choose

Measure your wrist circumference (wrap measuring tape where the watch sits):

Wrist Size	Recommended
Under 150mm (5.9")	Consider standard Watch 6 40mm
150-170mm (5.9-6.7")	43mm
170-185mm (6.7-7.3")	Either (personal preference)
Over 185mm (7.3"+)	47mm

Choose 43mm If

You have a small to medium wrist
You prefer watches that don't dominate
You'll wear it during sleep (lighter weight)
You want a balanced, proportional look

Choose 47mm If

You have a large wrist
You prefer bold, statement watches
You want maximum display visibility
You prioritize battery life (30-40% longer)
You like traditional large watch aesthetics

Battery Life Matters

The 47mm has a 42% larger battery but only 15% larger screen. This gives it a significant net advantage of 25-35% longer battery life. If you're torn between sizes and battery life matters, go larger.

Band Compatibility

43mm uses 20mm bands — Same as Watch 6 40mm/44mm, Watch 4/5 series
47mm uses 22mm bands — Same as Watch 3 45mm, original Galaxy Watch 46mm

Bands are not interchangeable between sizes.

Weight Comparison

Watch	Weight
Galaxy Watch 6 40mm	28.7g
Galaxy Watch 6 44mm	33.3g
Classic 43mm	52g
Classic 47mm	59g

The Classic is significantly heavier due to the stainless steel case and rotating bezel mechanism. Some users find this premium and reassuring; others find it uncomfortable for sleep tracking.

Try Before Buying

If possible, visit a Samsung Store or Best Buy to try both sizes on your wrist. Most people have an immediate preference once they feel the weight difference.
