What size and weight data should every jewelry listing include?

Give the dimensions that decide fit and appearance, in millimetres, plus weight in grams, stone sizes and available sizes or lengths. State how each figure was measured, and use the same format throughout.

Rings

Our advice Include band width, thickness, stone size, available sizes and weight.

Necklaces and pendants

• Chain length including clasp and any extender
• Chain width
• Pendant height and width, including the bail
• Weight

Earrings

• Total length or drop
• Width
• Post length and thickness, if relevant
• Weight per earring or pair

Bracelets

• Inner circumference or length
• Width
• Clasp type
• Weight

Stones

• Shape and size in millimetres
• Number of stones
• Carat weight, if stated, and how it is measured

It depends Sellers measure differently, so the same product may appear with different numbers. Describe your method, for example whether the length includes the clasp.

Add context

Our advice Show a scale in photographs and give a size chart where relevant.

Be accurate

• Weigh and measure a sample from each batch
• Update listings when the product changes

Presenting the numbers

Our advice Place measurements in a consistent list near the top of the product page, not hidden in a long description. Use the same units and order for every product, so that customers can compare pieces quickly. A short line explaining how to measure a ring or bracelet saves questions and cuts down on size-related returns.

Our advice Check the figures against a finished sample before publishing, and again when a new batch arrives. Small changes in thickness or stone size can slip in, and customers notice when a listing and a product differ.

Our advice Use the same units on every listing and say which they are, so that customers can compare products without converting. State whether weights are for one piece or a pair.

Our advice Where a measurement varies a little from piece to piece, say so, and give the typical value. Customers prefer an honest range to a number that is wrong on their piece.

Uncertain We cannot say which measurements matter most for your product. Ask customers what they need to know.
