Read length, width and girth on a bead listing
Match each measurement to the exact section it describes.
Keep the units and the labels together
Girth measures around a section. Width measures straight across it. Use dimensions with the same label for direct comparisons. A number without a labeled section needs clarification.
Keep overall and usable length separate
The B Yours listing gives both. The Onyx listing gives only a length and a girth. Ask which part is measured and use the product’s care instructions for its specific material.
