Ring Size FAQ

Does Omara offer half-ring size?

Yes! You can always order half-size rings to ensure you find the perfect fit. You can also request a design in a quarter size by contacting us via phone or email.

What if I order the wrong ring size?

If you order the wrong size, contact us to begin the complimentary resize process within 1 year of when your piece was initially shipped out to you. We'll confirm a new size with you and resize your ring free of charge. 

What is the average ring size for women?

The average ring size for women is between size 5 and 7, though this can vary greatly.

What happens when my ring is resized?

To resize your ring to the perfect fit,  our jewelers will add or remove a small strip of metal from the back of the band and solder it back together – you won't be able to tell it's been resized.

What is the average ring size for men?

The average ring size for men is between 8 and 10. Use our printable chart or order a free ring sizer to determine the perfect size.  

How do you secretly get the ring size

If you need to know your partner's ring size without them knowing, selecting a standard size or slightly larger size is the best choice. The average size for women's rings is 6, and for men's rings 9. You can also try measuring a ring they already wear or asking a friend or family member if they know their size. Whichever method you go with, always double-check the product detail page to confirm that your specific design can be resized to ensure you can eventually find the perfect fit. 

Does OMARA offer inclusive ring sizing?

We are proud to be one of the only jewelry brands to offer inclusive sizing across our entire assortment of engagement rings, wedding bands, and fashion rings.
