Choosing the correct ring size is important to ensure a comfortable fit and avoid unnecessary returns or exchanges. This guide provides helpful information to assist you in estimating your ring size at home.

💍 How to Measure Your Ring Size at Home

Measure an Existing Ring

If you already own a ring that fits well:

• Place the ring on a flat surface.
• Measure the inside diameter in millimeters (mm).
• Compare the measurement to the size chart below.

This method may provide a useful at-home estimate when measured carefully.

⭐ Professional Sizing Recommendation

If you are unsure of your ring size after using our at‑home method, we strongly recommend visiting a professional jeweler for accurate sizing before placing your order. Jewelers use specialized tools that provide the most reliable measurement, especially for rings with wider bands or unique designs.

🎁 Tips for Buying Rings as Gifts

• If you are unsure of the recipient’s size, consider choosing a slightly larger size when appropriate, but keep in mind that some ring styles may be difficult or impossible to resize.
• Ask a friend or family member if they know the recipient’s size.
• Compare a ring the recipient already wears (if available).
• Choose adjustable ring styles when possible.

⚠️ Important Notes

• Finger size can change with temperature, time of day, and hydration.
• Measure more than once for accuracy.
• Rings with wider bands may fit more snugly than narrow bands in the same size. Consider professional sizing for wide-band styles.
• Returns due to incorrect sizing follow our standard buyer’s‑remorse rules. See our Return & Refund Policy for details.
