Your Perfect Ring – Try it at Home

Not sure which ring to buy once you know your size? Try 3 rings at home before you commit — we'll send them with a second ring sizer so you can check fit and colour in person. Return them free and order the one you want.

“I used the ring sizer first, then ordered the Try At Home service to decide between two rings. The whole process was easy and I ended up with exactly the right ring.”
James, a UK buyer

Add Engraving When You Order

Once you know your size, add engraving at the same time as your ring order. We laser engrave in-house and dispatch the same day — your personalised ring arrives in 1–2 days with no extra delay.

“Ordered, engraved and dispatched within 12 hours of purchase, and arrived the next day after dispatch. What a service!”
Hailey Clarke — Croydon, London
Accurate measurement

Ring string gives a precise reading at knuckle and base

Any gender

Works for all ring sizes across the full Newman Bands range

Free option

A reusable ring sizer tool for measuring your exact ring size at home before you order. Works for any gender. Includes a ring string for an accurate reading at the knuckle and base of the finger. Tungsten and titanium rings cannot be resized — getting the size right first is the only way to avoid an exchange.

Yes. Select “I don’t know my ring size” from the dropdown on any ring product page and we’ll send you a free ring sizer. Once you know your size, email us your order number and size and we’ll dispatch your ring straight away.
Wrap the ring string around your knuckle and slide the sizer down to the base of your finger. The number at the arrow is your ring size. We always advise measuring your finger at a few different times of day — fingers are larger in the evening and in warm conditions.
If you’re between two sizes, we recommend sizing up — especially for tungsten rings, which cannot be resized. If you’re still unsure, contact us directly before ordering and we’ll advise.

Guarantee

100-Day "Try at Home" Returns

Buying a ring online shouldn't be a gamble. Try it on at home, check the fit, and see how it looks in person. If it isn't exactly what you wanted, simply return it for free within 100 days in unworn condition.

Fast, Hassle-Free Size

Ordered the wrong size? Don't panic. Our UK-based team makes swapping any unengraved ring for the perfect fit fast and painless. We usually process exchanges within days, so you're never left waiting. You're dealing with real people, not a warehouse.

Get Your Size Right Before You Order

Tungsten and titanium rings cannot be resized. Getting the size right before you order is the only way to avoid an exchange. This ring sizer removes the guesswork.

Works for any gender. Includes an accurate ring string for measuring. Reusable — keep it for future reference.

Not sure of your size at all? Select “I don’t know my ring size” from the size dropdown on any ring page. We’ll send you a free ring sizer with all the details you need. Once you know your size, email us your order number and size and we’ll get your ring sent straight away.

Simply wrap the ring string around your knuckle and slide the sizer down to the base of your finger. The number at the arrow on the sizer is your ring size. Sizes are sometimes a letter and number (e.g. J2) — the number on this tool gives you exactly what you need.

If you prefer to skip the ring sizer and take your time, no problem. Select the “I don’t know my ring size” option from the dropdown — no strings attached.

51 buyers of the Ring Sizer confirm it gives an accurate measurement and removes the uncertainty before ordering.

“The ring sizer arrived promptly, was extremely easy to use and gives an accurate measurement as well as being excellent value for money. A very useful purchase for all members of the family to use.”
Loralees, a UK buyer

Loralees noted it is useful for all members of the family — not just the person ordering. Elizabeth, a UK buyer, confirmed she is keeping hers for future reference, which is the point of a reusable tool. The most common reason buyers contact Newman Bands before ordering is uncertainty about ring size, and the consistent feedback from buyers who used the sizer first is that it resolves that uncertainty completely.

You have 100 days to try it at home. If it’s not right for any reason, return it free.
