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.

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.

GORGEOUS lightweight & dramatic

LOVE these earrings!
Such a statement, different but elegant so can be dressed up or down. So lightweight you don't know you're wearing them. Wind doesn't matter.
GREAT DESIGN!!!

I had one piece from insync design, which was a Christmas gift, which I absolutely love and I have been following this designer ever since. I have now purchased my 2nd and 3rd pieces on sale and I couldn’t b happier. They are stunning and of high quality. The earrings were bought to go with my first piece and they match beautifully. Will be purchasing more from this designer.

Love these earrings!

This is the second pair of earrings I have purchased from insync. Wearing these makes me feel breezy and interesting.

The light weight of these earrings makes them very wearable and the design goes well with any clothing.

Raw, edgy and sheik

Lovely original design earings. Light weight and loving the raw metal look.

My first Rose Gold inSync piece!

And what a stunning brooch! The colour so different to all the ones I usually wear and that, makes it so much more special. More so, the fact that it’s one of my favourite Australian native flower, can’t ask for more!

Stunningly Beautiful

I love blue. When I spied this brooch, I had to have the cobalt blue. It is a simple design goes with everything. Plus with any of my InSync necklaces & earrings.

Great if need hypo-allergenic-Red Pebble Earrings

I LOVE In Sync Designs unique statement jewellery & suitable for my metal allergy ... YEAH!
Over the years I've purchased 5 pairs of their earrings for my birthdays & Christmas.
From The Big Design Market in Melbourne, locally from Albury Gallery shop & now online.
Recently I purchased the Red Pebble Earrings LOVE the look they are on the heavy side but not too heavy unless windy. I prefer the squiggle part to be at the back so I bent the hooks over as it's easier to insert from front of ear than back of the ear, they look gorgeous.
I also bought the Flux Hoops that I LOVE, light weight in a unique modern hoop design.

Beautiful earrings

I was so fortunate to purchase the beautiful raw steel ringlet earrings from Iris. They are absolutely stunning and I feel so special wearing these, knowing that they are unique. The compliments I have received are so positive. Thankyou Iris

Lots of comments on the simplicity of the necklace. Love how it sits off centre.

Christmas come quick pretty please! 🎄

Cannot wait to get my hands on my Christmas present from my darling husband 🎅! My newest addition to my InSync collection, the Cluster necklace in black!
It’s such an eye catching piece of jewellery, and I know that because I also have it in gold 😂

Great extra to extend earings

Lovely extra to add to a number of studs. So light and they fall beautifully.

So Stylish and Unique

Absolutely love my earrings that arrived beautifully packaged. Stylish and unique. My first purchase and won’t be my last . Thank you so much Iris.

Uniquely beautiful design

This broche is a real jewelry that makes any piece of clothing - look special. Its looks sophsiticated, but in the same time - modest, it is gorgeous both on business jackets or evening little black dresses. I recommend getting also same design earings, then your evening look will be totally special.

I love it!!

I really love this piece it is so cool with a shirt or even a white Tshirt.

Gorgeous- I want one in every colour!!

Curvaceous

As I swim in the ocean, I watch the waves. These Fay earrings allow me to have the surf with me always. Insync designs are the best kept secret.

Gorgeous brooch

I bought this for my son’s girlfriend who has just been admitted as a solicitor and we both love it! Such a simple yet stunning piece!! A wee bit envious haha

Beautiful earrings, so light and comfortable to wear too. They elevate any outfit. Love them!!

Love it

Beautiful brooch. Another beautiful piece. Thank you so much.

Nina, thank you for your kind words. I am so glad the brooch has found a home with you, and even happier to know it joins your inSync collection. May it bring you joy each time you wear it. Iris x

I am so excited to add this gorgeous brooch into my collection of inSync design items. I love it!

Delightful

This is a delightful necklace. A good bit smaller than I hoped as I planned to wear it with bigger sort-of matching earrings. Cord a little less firm. Still I do enjoy it, Iris. Thanks for you me superb eye and creativity.

Thank you so much for your kind words Frances, and for your honesty, too. I’m really touched that you still find the necklace delightful, even if it turned out a little smaller and softer than you expected. Every piece is designed to feel good and bring a bit of joy, so I’m glad to hear you’re enjoying it nonetheless.
Your appreciation of the design and my “superb eye” (what a lovely compliment!) truly means a lot. I’m always refining and exploring, so feedback like yours helps me grow and inspires future pieces that might just be the perfect match for those bigger earrings 😊

Curl Necklace - Matt gold

I was looking for something to wear with v-neck linen shirts and cashmere jumpers and think this necklace will meet my requirements. It’s pretty and light and fun!

Thank you so much for your lovely words Margaret, I’m glad the Curl Necklace fits so beautifully into your wardrobe! I designed it with exactly that kind of effortless elegance in mind, something light, a little playful, and easy to wear with those timeless pieces.
It means a lot to know it resonated with you and I hope it brings you joy (and compliments!) every time you wear it. Iris x
