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.

  • Oh my I’m so pleased and delighted to be among the many here on this site that have provided their sincere praise of Wedding Bands.com… Initially my fiancée and I selected our rings at a brick mortar jewelry store! The rings had to be ordered however after arriving and looking at my ring that day a bit closer I discovered a slight flaw in the design that we had chosen! Unfortunately we returned my ring and was later told my size was not available…I was devastated! We looked at several stores and decided to look online and I’m extremely happy that we did. We came upon Wedding Bands.com and completed a search and there was my ring!!!! I placed an online order after reading over all of the online information to include testimonials shipping return policy etc. however before pulling the trigger and finalizing the sale I called the company! My fiancé and I were very pleased that all of our questions were answered the sales associate/representative was extremely pleasant and knowledgeable the representative even asked the date in which we would need them! So we made our purchase and they arrived in about 8 days. We are so very please happy excited with our purchase and looking forward to the day when we exchange our vows with my ring from Wedding Bands.com!! Thank you all so very much

  • Back in 2016 when we decided to finally make it official we ironically had 12 days to plan our wedding....and it all honestly fell into place as if it had been planned for a very long time. We found wedding bands.com online and found the perfect ring....the Grand Canyon....it was truly a mix of us... yellow gold and white gold both polished and satin in a wave design around the band. We ordered them and can honestly attest this jeweler is amazing! We got the rings in time for the ceremony and since then we have sent both of them back for inspections and refurbishing. As our 7th anniversary was approaching 10/23 we contacted the jewelers and scheduled our bands to be sent back to be inspected refurbished and refinished. This company is beyond professional...in communications and advice on the products they create and take pride in taking care of. They kept the rings for almost 3 weeks giving them the time to make them look new again and today we received them back...looking like they did the day the originally arrived 7 years ago. They communicated with us by email and phone from our initial contact to send them back for inspections/refurbishing and followed up till they arrived back to us today. They are the type of organization that existed years ago in the old days....they take great care in what they create for you and take great pride in keeping you as a satisfied customer....we recommend them highly definitely a 10+ in todays retail world.

  • 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.
