Ring size basics

Our rings come in various widths (ranging between 20-35mm) that change as the drawn line undulates and wraps around your finger, so it's important to measure carefully for the perfect fit.

To get started, you can either measure the inner diameter of an existing ring or measuring your finger directly. For the most accurate results, we recommend measuring your finger size several times to eliminate errors.

To determine your ring size we recommend using our ring size chart and helpful tips below. Here's how:

How to measure your finger circumference

To measure your finger size directly, you will need a piece of string, a marker, and a measuring tape or ruler. Cut a piece of string long enough to wrap around the base of your finger (make sure it's at the widest part of your finger) and ensure it's a snug and comfortable fit. Mark where the end of the string overlaps and lay the string flat against a ruler or measuring tape to measure the length in millimetres. Use the Ring Size Conversion Chart below to find your correct ring size.

How to measure the inside diameter of an existing ring

If you have a ring to compare, you can use a ruler or measuring tape to determine the diameter of the inside of the ring.

Measure across the centre of the ring from the inside of one side of the ring across to the other. It can be tricky, so make a couple of attempts and use the largest measurement you got which will be the most accurate, then find the corresponding ring size in the chart below.

Now you have your two measurements, refer to the ring size chart. You only need one measurement but using the two will give greater accuracy.

See below an approximate size guide for the inSync rings:

Size S - Size 5-6

Size M -  Size 7-8

Size L - 9-10.

Things to keep in mind when measuring a ring

  • The inSync design rings should NOT be measured similarly to a wedding band as they have a wider grip on the finger. We, therefore, recommend selecting one size larger than you normally would with a thin band.
  • It's important to keep in mind that your ring size and finger size are two different things. A ring is a rigid material that will not conform to the shape of your finger. Your finger size changes shape and size over time and also swells and shrinks with different temperatures. 
  • As your finger size changes shape and size over time and it swells and shrinks with different temperatures. When measuring a ring, make sure the finger is at a normal body temperature – fingers can expand or shrink when hot, cold, or damp. Your fingers tend to change size throughout the day, so the best time to measure your finger is towards the end of the day when it is at its largest.
  • Your dominant hand is generally slightly larger - ensure you measure the finger that the ring will be worn on most, on the correct hand!
  • If the ring size is between two sizes, we recommend sizing up just to be safe.

Gift for someone special?

If you’d like to buy a surprise gift, and you can borrow one of their rings, use the ring size guide above to determine their correct size.

Otherwise, if you can put their ring on your finger (pick a finger where the ring fits as close to a normal position as possible). Mark two marks, one on either side of the ring. Leave the marks on your finger and visit a jeweller to find out what size ring fits between the two marks.

Ring size help or Still unsure?

If you're still unsure about your size, don't worry! We are happy to exchange your inSync ring for another size or style, provided it is in its original condition/packaging.

Our rings come in various widths ranging between 20-35mm that change as they undulate along the drawn line. They should NOT be measured similarly to a wedding band as they have a wider grip on the finger. We, therefore, recommend selecting one size larger than you normally would with a thin band. In order to determine your size, you can either use an existing ring that fits you. Align it over the circles below, making sure the INSIDE of the ring lines up with the circle. If you are between sizes, we recommend ordering the larger size.

ring sizer

Alternatively, cut the ruler below and wrap it around your finger to measure your finger circumference.

1. Print this page and cut out the Ring Sizer below. Use a utility knife to cut a slit in the ring sizer.

2. Wrap the Ring Sizer around your finger. Then poke the pointed end through the slit with the numbers facing out.

3. Tighten the Ring Sizer by pulling the pointed end toward your finger. The fit should be snug but comfortable around the widest part of your finger (normally at the knuckle)

4. Simply read the number at the slit. if the size falls between 2 numbers use the larger one.

Just feel so stylish

Hi Iris, have loved my previous inSync earrings, was devastated when I lost one, contacted you & you made me a replacement. (Love you dearly for this🤗🥰).
Love the Contra Brooch & earrings, get lots of comments & compliments.
Feel so special wearing art pieces, thank you.

Thank you so much for the lovely review Toni, it made my day!
I'm thrilled to hear how much you're enjoying your inSync pieces, and I'm glad I could help with the replacement earring.
It's fantastic that you're getting lots of compliments and thank you for sharing your thoughts, I truly appreciate it!

Maybe my fave!

My husband noticed!!! 😉

Today I wore the silver contra brooch, (I also have the red one, for another day…) when I got home my husband said ‘oh what a beautiful brooch, is it new?’ Hahaha, what can I say, love, love, love inSync pieces of art! Just can’t help myself, makes me feel so good and that’s what matters 💕

I'm so happy that your husband noticed and loved your new brooch. I love knowing that my pieces make you feel so good—that’s exactly what I aim for! Next time I would suggest layering the silver and red Contra brooches together, it will have a lovely effect!

Enjoy wearing your brooches, and thanks for being such a fabulous part of the inSync community. Sending you lots of love!

Really like these

I really like these earrings. They are silver and black anodized aluminum,. They are very light and comfortable to wear. All good!! Well done Iris!

Thank you so much for your kind words Debra, I appreciate it! I'm thrilled that you love your earrings and find them light and comfortable. Enjoy wearing them and the compliments they bring ;)

Beautiful earrings....not exactly what I was expecting, but beautiful.

For some reason I thought these were enamel....they are not. They are colored metal. I love the color and the length.

One note, Iris - I got two earrings that go on the same side. You want the channel for the ear wire to be on the inside, and in my case I got two with the same orientation, so one is on the outside. My hair covers it, though.

Overall, pleased with my purchase and happy to support a small business.

Hi Debra,
Thanks so much for the your five start review, i appreciate it. I am pleased that you love the colour and length of your earrings, but I wanted to clarify that the earrings are made from anodised aluminum, rather than enamel.

The decision to have both closures on the same side was made to help keep costs manageable. Since the earrings hang sideways like a hoop, the clip remains discreet and out of sight, ensuring the design remains elegant while being cost-effective. Creating two oposite sides would have significantly increased production costs, and I strive to balance affordability with quality.

Thank you again for taking the time to review the earrings and for your your support. I hope you will continue to enjoy your earrings and feel stylish and unique while wearing them. Warm regards, Iris x

Another pair of earrings

I have three pairs of Pebble earrings and a pair of Plunge earrings. I love them all. The Pebbles travel overseas with me because the catch is so good I know they will never slip off. And they are so tactile and striking, dressing up any outfit.The Plunge earrings are so stylish and my dress-up go to. So why did I need another pair - clearly I didn’t, but the Meander studs are just irresistible. Perfect size and weight with the most gorgeous contours. Thanks Iris. Your designs are always so innovative.

Thank you so much for your amazing review Kris, I appreciate it! I’m thrilled you love your Pebble and Plunge earrings, especially that they’ve become your trusty travel buddies and go-to for dressing up. I’m really excited that the Meander studs have won you over as well—they’re a personal favourite of mine too! Your kind words about the designs mean everything to me. Thanks so much for your support, Iris x

Orbit Ring

Have been looking for a ring with a difference.
Came across inSync design.
What I found was unsual, different and most beautifully crafted handmade pieces of art.
The piece that spoke to me was the Orbit ring. I'm in love with this piece of difference.
On arrival, my purchase was beautifully packaged and on opening there was a personal message to me.
Will be buying more pieces to add to my collection.

Thank you so much for your kind words Irene and for choosing the Orbit ring from inSync design! I’m thrilled that you're in love with your new piece. I take great pride in crafting unique and beautifully handmade pieces, and it means the world to me that my work resonates with you. Enjoy wearing the ring and the compliments it brings ;)

LOVE THEM!!

I have bought the earrings because I already have a necklace from InSync that I love it’s so light (perfect for hot weather) and looks stunning.
I love these earrings because they’re so sculptural in design, the quality is excellent and I’ve had lots of compliments when I wear them.

I'm thrilled that you're loving your new earrings! It's wonderful to know that my pieces have become staples in your collection, especially since you already adore the necklace. I totally get the need for lightweight accessories, especially in hot weather, and I'm so glad that our earrings are hitting the mark in terms of comfort and style. Your appreciation for the sculptural design and quality craftsmanship means a lot to me, and I'm truly grateful for your support. :star2::sparkling_heart:
