Ring Size Guide

Getting a perfectly fitting ring doesn’t need to be like trying to

hit a moving target.

Ring size can be tricky if you are not aware that your finger size can

change depending on a variety of factors – like the season, weather,

time of day, diet, medication, etc. Then the width and shape of the ring

can also affect the ring fit.

There’s nothing more frustrating than falling in love with a ring, only to find out it

doesn’t fit correctly once you put it on your finger. So, how do you know what ring

size you are? And what should you do if you’re between sizes?

If you’re not sure what size ring to buy, don’t worry— we are here to help you! You

can use on of these easy methods:

European, German, Japanese, and Swiss size to US comfort fit.

Option 1. Measure an existing ring

Choose one of your rings.

How To Measure:

1. If you measure the inner diameter of your ring (in mm) it should match with the corresponding

size in the ring chart below. Be sure to use millimeters, because it’s more precise when it comes to jewelry. Measure the inner diameter of the ring using a ruler.

The inner diameter is the only cold, hard measurement you can trust. Once you

have this, you can compare it with our ring size chart below so you know

exactly what size to order.

​Please note that the ring size illustration above is not displayed to scale.If your size is between two sizes, go for the larger one

Option 2. Measure your finger with a string 

Measure a ring with a string (don’t use a elastic material) or a thin strip paper.

This can be easily done and can help find an accurate fit.

1. Cut a long string or piece of paper.
2. Wrap it around the finger you’ll wear your ring on, snugly around the base of your finger, the tighter the better but make sure to not let the string stretch while you are wrapping it around your finger.

      3. If you’re creating a ring stack, consider where on your finger the ring will              sit—and mark the place where it joins. 

4. Mark the spot where the where the two ends overlap and measure the distance with a ruler (in mm).

5. Match your finger measurement (in mm) with the closest circumference below.

Option 3. Measure your finger with a measuring tape

If you happen to own a measuring tape at home, then this is will get the job done most accurately.

1. Find a flexible, measuring tape with millimeters on its ruler.
2. Wrap it around the finger you’ll wear your ring on the tape, snugly around the base of your finger, not too tight and not too loose. Aim for a snug but comfortable fit. Make sure to not let the measuring tape go and make sure you start from the 0 mark on the tape.

3.if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins. 

4. Remember the number that meets up with your starting point at 0. Note how many millimeters

it took to wrap the measuring tape around your finger.

5. Match your finger measurement (in mm) with the corresponding ring size in the ring chart shown in method #02. If your tape is only showing in centimeter, use an online CM to MM

converter to figure out your finger size in the closest millimeter. (But as an example 5,5cm = 55mm).

Ring Size TIPS

1- Measure your finger at the time of the day when it will be at its largest – usually at the

end of the day. Please keep in mind, your ring size can fluctuate about a half size based

on your temperature, hydration levels, and hormones.

2- Make sure to measure your fingers are at room temperature to get a more accurate, avoid

measuring your fingers when they are cold and damp.

3- Did you know your ring feels tighter in the morning than in the evening? So you

should measure your ring size in the afternoon and not in the morning

because our fingers will usually shrink in the morning due to the lowered

body temperature.

4- Bands and rings over 5mm in width may fit your finger more tightly than rings of the

same size in a narrower widths, since the width changes the surface area in contact with

your finger, which affects how tight or loose the ring fits. So it might be a good idea to go

for a slightly bigger sizer than usual if you are buying a eternity band.

5- Avoid measuring your fingers after you had some salty snacks and a couple of glasses of wine because alcohol and salt can make your fingers swell

6- If you are  between sizes, we recommend ordering up. It’s always easier to size a ring

smaller, than larger.

7- Did you know your dominant hand has a larger ring size than your non-dominant hand?

8- If you’re between sizes, go for the larger size of a ring or bracelet—it’s easier to size down than size up. 

IMPORTANT NOTE: Because sizing can differ so easily from jeweler to jeweler, we have provided the industry standard table that we use. If you know the inner diameter or circumference, in millimeters, you should be able to determine your ring size. We guarantee that our rings will be manufactured within a variance of +/- 0.1 mm against the published measurements in our chart.

If you are still unsure about sizing and need further assistance, please reach out to customer service and we can send you our complimentary ring sizer.
