Love it

It's so easy to use, very convenient, and will use for years to come.
I've recently lost weight so the sizer will help keep me in with my ring sizes. I love it. Thank you Simple & Dainty for being a small business owner. As from personal experience, they put the most love in their products.

Ahh, this made our day, Randi! So glad you love the ring sizer and are finding it so useful. Thank you so much for your sweet words and for supporting our small business :)

Great little tool

I had been using a measuring tape to measure my ring size and was always getting it wrong! Got this ring sizer (free) from Simple & Dainty and voila! So easy to use and now I know all 10 ring sizes 😂

Haha love this — so glad it made things easier for you! Thanks for sharing, Ann :)

Different, yet Dainty

I ordered the "Thin Flower Band Ring" after receiving a complimentary ring sizer. Only shipping needs paid for for the ring sizer, and mine was like $5 for total price.

The ring sizes for Simple & Dainty are heterodox: no "1/2" sizes. All numerical sizes are whole numbers, which makes your ring size differ from that of other companies'. That being said, the size discrepancies are also straightforward; not a hassle at all.

When she finally received the ring, she loved it! I'm completely happy with what I received.

Aww, thanks so much for sharing, Matthew! We’re so glad she loves her ring and you're happy with your purchase. Really appreciate your feedback about sizing—it’s helpful for others to know. Thanks a ton for your support :)

Perfect

I was desperate and used a printout ring sizer I found online and of course ended up ordering the wrong size. I added this ring sizer to my order and I’m so glad I did. It was easy to use/read and feels durable, I see it lasting. Once I took the correct measurements, Simple&Dainty made it so easy for me to exchange. Thank you!!

YAY! So happy you found our ring sizer useful. Thanks a ton for your kind words and support of our small business, Karina :)

ring sizer

I ordered the ring sizer along with three rings as a gift for my daughter. Well, I guessed wrong on her size. The ring sizer allowed us to find the correct size. Simple and Dainty promptly exchanged the rings for the correct size. What more could you ask for?

You’re so sweet, Linda!! I’m so happy the ring sizer was helpful & the exchange went smoothly. Thanks a bunch for your kind words :)

BUY FIRST

I originally purchased this ring sizer first but got antsy and ordered my rings before this arrived. And i should have waited, as i ordered my rings one size too small. But now i know and will be gifting the smaller set and reordering in my size. Great little thing to have around for future orders too!

Accurate and easy to use

So Nice!

I love that this was free. It’s a perfect ring sizer too! I never knew my ring size, but always wanted to purchase some rings online. So I got this sizer, measured my fingers, and I then purchased the love knot ring from this shop, and it was a perfect fit! Definitely going to be using this frequently because it works great! I can’t wait to buy some more rings now, knowing that this is an accurate sizer!

Good for general sizing

I had a few ideas on what my ring sizes were for a couple of my fingers so I went ahead and bought some rings for those but I wasn't totally sure on the sizing for all of my fingers so I got this ring sizer in case I wanted to get rings for the other fingers. It's great for helping you find your general sizes but I think might be off by a half size either due to the material (the plastic is a bit stretchy) or the thickness (it's thicker than most stacking rings) so it feels more comfortable at a smaller size measurements.

J
Jeslyn Kim (Santa Clara, US)
So helpful

So kind of Simply & Dainty to make these available for free. I have really thin fingers and never knew my size, so it's always difficult to find the perfect ring when shopping online. Thank you!!

Genius

What can I say, it works. Definitely useful if you plan on ordering a ring for a specific finger.

Useful!

I added the ring sizer to my order when I purchased a necklace from Simple and Dainty and it is very useful because I wanted to purchase some stacking rings but didn't know what size to purchase, so this is a very handy thing to have!
