Which dimensions matter when comparing wearable designs?
Find the relaxed opening, overall space and exact adjustment description.
Check which part was measured
Ring length, relaxed opening and overall outer size are different measurements. Record the units and where the maker took them. If a number appears ambiguous, ask the manufacturer for a labeled view of the exact SKU and color.
Find the adjustment and release information
Look for a model-specific explanation of adjustment and removal. If those details are missing, ask the maker what range they publish and which parts can be released independently.
