How to Determine Your (and Her!) Ring Size

The best way to determine your (and her) ring size is to stop by any Robbins Brothers and we’ll be happy to provide an accurate measurement. But if you want to measure your size at home, you can use our at home ring sizer and measurement tips.

Our measurement guide is useful whether you’re looking for an engagement ring, wedding band, or fashion ring. Remember that the engagement ring and wedding band are worn on the fourth finger (ring finger) of the left hand, and fashion rings are worn on any finger.

With most rings, you can order as close to the correct size as possible and then have it resized. But some rings, such as eternity rings can’t be resized to verify before purchasing whether a ring can be resized if you’re not sure of the exact size.

Tips:

Ensure you print the ring sizer at 100% size (and not “shrink to fit” or “expand to paper size”). Confirm the printed version is the current size by measuring the provided verification measurement to ensure it is exactly 2 inches.
Weather impacts finger size. When it’s hot, our fingers swell and when it’s cold, our fingers are thinner.
Right and left hands can vary in size, so be sure to measure the ring you’ll wear the finger on.

How to Find Her Ring Size And Still Surprise Her

If she has a ring that she wears on her right ring finger, you can use our ring sizer guide to determine the size of that ring. Remember that her right ring finger may not be exactly the same size as her left ring finger, so make sure that if you buy a ring using this method, it can be resized.

You can also get an accomplice (such as her friend, sister, or mom) to find out her ring size.

Also remember that it’s fun and romantic to go ring shopping together before you get engaged so you both can dream about your future together and you an get a good idea about her style and what she likes. During those shopping trips, make sure to ask the salesperson to get both of your ring measurements!

Wedding Band Sizing

Wedding band sizing is the same as engagement ring sizing. Another sizing factor to consider with wedding band sizing is band width. Wedding band widths are measured in millimeters. Women’s wedding rings generally range from 2-4 millimeters and men’s wedding rings generally range from 6-8 millimeters. The best wedding band width is the one you prefer! Wedding bands widths are all about the look and feel of the band.
