Measure at home with our ring sizing guide. If you are between sizes, choose the larger size. Stainless steel and tungsten often feel a little snugger than sterling silver.

Get the size right before you order. Stainless and titanium often feel a little snugger than softer metals. If you are between sizes, the larger size is usually more comfortable.

Wrong size after it arrives? See Fit or Credit — store credit or a size exchange, with you paying the return label. We do not send free prepaid return labels.

How to measure

1. Paper strip. Wrap a thin strip of paper around the intended finger (the one you will wear the ring on). Mark where it overlaps. Measure that length in millimeters. Match it to the inside circumference in the chart below.
2. A ring that already fits. Measure the inside diameter in millimeters (straight across the inside of the ring). Match it to the chart.

Measure at the end of the day when fingers are a bit larger. If your knuckle is bigger than the base of the finger, size for the knuckle so the ring can pass, then sit.

US ring sizes

Half sizes sit halfway between the whole sizes on this chart.

Newest collection / special-order rings

Some styles are ordered for you when you buy. Delivery is often around 11 days and can take up to 3 weeks. Fit or Credit still applies if the size is wrong. It is not a change-of-mind return.

Questions? Email ringguru@proton.me with your order number.

If the size is wrong: store credit toward another MyRingGuru piece, or an exchange for a different size of the same style when stock allows. You pay the return label. Email ringguru@proton.me with your order number.

We want your ring to fit. If the size is wrong, we offer a simple Fit or Credit path — not a free “ship it back on us” return.

What we offer

• Store credit toward another MyRingGuru ring (or eligible MRG item), once we confirm your claim, or
• An exchange for a different size of the same style (when stock allows), with you paying the return-shipping label

We do not offer free prepaid return labels that eat postage. We do not promise 2-day shipping on items in our newest collection that take longer to ship. Metal and stone descriptions match what we sell; we do not invent materials.

Before you order

• Use our ring sizing guide. Stainless bands often run differently than soft metals — measure carefully.
• Check the product page for honest ship timing. Items in our newest collection can take longer; we will not advertise 2-day ship on a longer path.

If the size is wrong

1. Email us with your order number and what went wrong (too big / too small / which finger).
2. We’ll reply with the options that apply: store credit and/or exchange with customer-paid label.
3. For an exchange: buy/print the label we specify (or your own prepaid method if we agree), ship the unused ring back, then we send the replacement size when we receive it (or as we outline in email).
4. For store credit: we’ll apply credit to your account / send a code once the claim is approved (and after return receipt if we require the item back).

What we ask

• Ring unused, unworn beyond a careful try-on, in original condition, with tags/packaging when provided.
• One Fit or Credit claim per order line unless we say otherwise in writing.
