US Ring Size Guide

Choose the size for your finger, the design and the way you wear it.

Morrow Carat ring options use the size system stated on the individual product page. When an option is labeled US, choose your US ring size. A number from another sizing system is not automatically the same size.

A quick US size reference

The measurements below are approximate inner diameters. They are a starting point for comparison, rather than a promise that a particular ring will fit. Only sizes listed for the piece are available to select.

US ring size Approximate inside diameter
US 5 15.7 mm
US 6 16.5 mm
US 7 17.3 mm
US 8 18.1 mm
US 9 19.0 mm

Start with a ring that fits

Choose a ring that fits the same finger on the same hand. Measure the clear space across its center, from the inside edge to the opposite inside edge. Exclude the metal itself. A jeweler can help check the size with a proper gauge.

Consider the band

Fit can feel different with a wider band or a different inner profile. If you are between sizes, buying a gift or choosing a broad design, have the fit checked before selecting the final option. Do not assume a stock ring can be resized or that resizing is included.

Before you request your piece

Check the size label, selected option and SKU together. If an old ring uses a different sizing system, tell us which system it uses and ask us to confirm the matching option for the piece before ordering.

For a question about a specific design, contact Morrow Carat with the product link and your size. Read how ordering works before submitting your request.
