How To Size Your Finger Perfectly

Knowing the size of your finger so the ring will fit correctly is one of the trickiest aspects of buying a ring online. Even if you go to a jewelry store, you can never be too certain if the person behind the counter gets it right.

At WeddingBands.com we solved this problem by giving free ring sizing kits that are sent directly to you at no charge. You can size your fingers in the comfort of your own home and see what fits you the best without any doubts. Use the following guide to ensure a perfect fit of your wedding band.

  1. Request a ring sizing kit through the following form: Ring Size Request Form
  2. When you receive your kit, take the blue plastic kit and punch out the ring sizes you want to try.
  3. When you try the different sized rings on keep a few things in mind:
    1. The ring should go on easily.
    2. The ring should feel comfortable on your finger.
    3. It should come off with a little resistance.
    4. If you think you're between our half sizes, don't fret, we offer quarter sizes on all our rings on WeddingBands.com.
  4. Once you know your size, you can order your ring from our site with confidence that your wedding band will fit you perfectly.

We guarantee using our sizing kit will ensure an ideal fit from any of our wedding bands. If it doesn't, please feel free to use our 30-Day Return/Exchange policy to find a better fitting ring.

Also, if you know your size but it's in a different metric than the standard U.S. ring metric, you can use our ring sizing conversion chart to find out what your U.S. standard ring size is.

As always, we are here to help, give us a call at (888) 422-4333 or shoot us an email at CustomerService@WeddingBands.com with any questions or comments.

  • I have for many years wanted an extra wide band. My husband purchased a second band 7mm for me when my first band cracked apart. No grief there because I never liked it anyway. My finger size has changed as I have aged and my second band became tight on my finger. I finally took it off before I would have to have it cut off. We started shopping at local jewelers and pricing the type of band that I wanted. None of the jewelers had bands as wide as I was looking for especially in the ring size I needed. Thank goodness for WeddingBands.com. I found the EXACT width of band I wanted 10mm and in the perfect ring size. I felt very assured of my purchase because of the return policy provided. I am very pleased with my ring and the service provided. Thank you.

  • Two-Tone Gold Comfort Fit Wedding Band - Item 110361. My wife bought this wedding band to replaced the one that I had lost while on a camping trip. This is the exact Byzantine Rope- Coil design that I had for over 25 years. I thought I would never be able to find the exact design ring but WeddingBands.com had it. The quality is nothing less than excellent. The support representatives were great.
