How to Measure for Jewellery


A local jeweller such as Diamonds and Pearls know a lot about jewellery, including styles, metals, stones, and recommended retail pricing. What they don’t know, however, is your significant other’s ring size, or how the particular sizing of necklaces, bracelets, earrings, and rings works with your body shape and size.

Even if you plan on seeing jewellers in secret, so your partner doesn’t know you’re surprising them or you are planning wedding gift, you need to be aware of sizing. If you don’t, you may find it more challenging to pick something out they’ll like or will fit them perfectly.

Of course, when you do visit a jeweller’s store and pick out something, you can return it if it doesn’t fit or you want to resize it. However, if you can get it right the first time, you can avoid that hassle, and you or your loved one can wear that piece forever. Measuring for jewellery is easier than you think.


Even if you’re shopping for yourself, you may find it challenging to buy a necklace that works on your body shape. Often, it can also seem like more hassle than it’s worth to try on every single necklace you like. So, rather than pay attention to measurements, many people buy a necklace from their local jewellers then put up with the fact it doesn’t suit them.

A 400-410mm necklace is going to sit more like a choker chain with minimal give, whereas something between 430mm to 490mm will sit on the lines of your collarbone. If you prefer something a little longer, a necklace over 550mm will hang around the neckline, while over 600mm will be below it. Specific necklace styles suit different clothing and body shapes, so keep this in mind. Anything below 420mm can limit how many outings the necklace will get with apparel.


Most bracelets you will find within a jewellery store are easy to measure with a measuring tape or ruler – especially loose bracelets with clasps. However, bracelets without a closure system such as bangles require you to measure the inner circumference, adding on any measurement from an opening point as well. If you are buying a solid bangle for your significant other, try to find out what their wrist measurements are. If you can’t, measure a bracelet they wear all the time to get a gauge of what will fit.


Whether you’re buying a ring for you or your partner, you will find the measuring process can be a little daunting. Everyone has a different finger size, which makes shopping for rings akin to shopping for clothing – a slow process. You can make ring shopping far easier if you have already measured your ring size in advance.

Wrap string around your finger’s base, mark the string at the joining point, then measure it with a ruler. You can then use a jeweller’s sizing chart to compare your millimetre measurement to a ring size. For example, a 68.3mm finger equates to a size 12.5 ring in the United States.

When you’re shopping for jewellery, it’s helpful to be aware of approximate measurements for all jewellery you are considering purchasing. However, if you aren’t able to get them, you can rely on your local jewellers to be of assistance with choosing the perfect ring or other item for your loved one.
