Oval Solitaire Engagement Ring

A well-chosen ring size should feel secure while still passing comfortably over the knuckle. Because fit varies by finger, band width, and design, use the guidance below as a starting point.

Best option: professional measurement

For the most reliable result, ask a jeweler to measure the intended finger with a professional ring sizer. If possible, use a sample with a band width similar to the ring you plan to order.

Using a ring that already fits

A jeweler can measure the inside diameter of a ring that fits the intended finger. Confirm that the existing ring has a similar profile and is worn on the same finger and hand.

Measure under normal conditions

• Finger size can change with temperature, time of day, and temporary swelling.
• A wider band can feel tighter than a narrow band in the same nominal size.
• Do not rely only on string, paper, or an uncalibrated screen measurement.

Check the product before ordering
