How to Measure Jewelry Size and What to Consider

Accurate sizing is essential for comfort and long-term use. When measuring ring, bracelet or necklace sizes, it is important to use a standardized measuring tool and to account for natural variations in finger or wrist size throughout the day.
Temperature, humidity and hand activity can affect measurements, so taking multiple readings is recommended. A precise size ensures an ideal fit, enhances wearability and protects the structural integrity of the piece.

How to Measure Jewelry Size and What to Consider

Accurate sizing is essential for both comfort and long-term wear.

A perfectly sized Earthpiece feels natural on the body — balanced, effortless and secure. Understanding a few key principles helps ensure that your piece fits the way it is meant to.

Measure With Standardized Tools

For rings, bracelets and necklaces, using a standardized measuring tool is the most reliable method.

International jewelry guidelines (ISO 8653 for ring sizing) show that even millimeter-level differences can change the fit, especially for everyday wear.

A proper measurement eliminates guesswork and supports structural integrity over time.

Account for Natural Changes Throughout the Day

Fingers and wrists naturally shift in size due to:

• temperature changes,
  
  

• humidity,
  
  

• salt intake,
  
  

• physical activity.
  
  

Studies on peripheral circulation show that finger diameter can fluctuate by up to half a ring size during the day.
