How would you like to find your size?

Numeric size (e.g. 8) for US/Canada, EU, or Japan — or a letter size (e.g. P 1/2) for UK/Australia.

CaratLane sizing accuracy & everyday diamond ring fit

CAD-precision manufacturing, solitaire bands, and stackable ring guidance.

Omnichannel fine jeweler CaratLane (a Titan Company partnership) crafts rings using precision 3D CAD modeling aligned with standard Indian millimeter dimensions. A CaratLane size 11 measures 16.1 mm inside diameter (approx US 5.75 / UK L), while size 13 measures 16.9 mm diameter (approx US 6.5 / UK M½).

Online Sizing Tips: When buying engagement solitaires or everyday fashion rings on CaratLane, measure your finger's inside circumference at room temperature. If stacking multiple bands or buying a broad cocktail ring, consider sizing up by one full Indian size.

Lower-confidence data — Japan, India (VowJewels), India (The Vedic Crystals) comes from a single published retailer source, or is known to drift by 1–2 sizes at the top of the range. Confirm with the retailer before ordering.

Rounded scale — Germany / Netherlands uses a coarser step than US half-sizes, so one value can cover two neighbouring US sizes. Check the millimeter columns when you need to tell them apart.

Frequently asked questions

How accurate is CaratLane ring sizing?

CaratLane follows the standard Indian ring size scale (sizes 6 to 30). Because CaratLane jewelry is precision-crafted with CAD technology, their rings fit exactly to standard millimeter diameter and circumference specifications.

Does CaratLane offer free ring resizing?

Yes, CaratLane provides a 30-day resizing policy for most gold, diamond, and platinum rings (subject to design constraints; full eternity bands cannot be resized).

What if my CaratLane measurement falls between two sizes?

If you measure between two Indian sizes, CaratLane recommends sizing up for bands wider than 4mm and sizing down for slim, delicate solitaire bands.
