Jewellery Size Guide - Jewellery Measurement Tips

At one point or another, we’ve all bought a piece of jewellery that is so irresistibly eye-catching that we just could not help but make it our own; only to come home and find out that it is just a tad too loose or tight. Or we’ve wanted to buy the perfect ring at a great price during Boxing Day sales, only to be confused about sizing. 

Not many people realise that understanding jewellery measurement is critical to a good shopping experience! So here’s our jewellery size guide, where you can find out everything you need to know about discovering your jewellery size, plus tips to measure yourself.

What You Should Consider:

Buying rings can be a tricky business unless you know exactly what you’re looking for. This becomes trickier still when it involves purchasing it for someone else, as in the case of an engagement ring! And who on earth would want to ruin that surprise by asking their significant other for their ring size? All of this can be avoided by taking the basics into account.

So, for starters, consider which finger this ring is being bought for. Is it a fancy cocktail ring like the Sterling Silver Amethyst 14x12mm Cocktail Ring (Figure A) which can be best suited for the middle or forefinger? Or is it a minimalistic band like the Memoire 18ct White Gold 1/5 Carat Diamond Eternity Band with 3/4 band of Diamonds (Figure B), which can glide onto any finger? Not sure which finger to wear rings on? Check out our blog! 


Once you have this figured out, you’ll have a general idea about the fingers that are narrower or wider than the rest. One aspect to keep in mind is the knuckle. If you know your knuckle is on the larger side, measure your finger and then order half a size bigger than what your finger alone indicates, otherwise you won’t be able to slide a ring into the right place.

5 Ways To Measure Your Ring Size:

If you’re asking yourself, ‘what is my ring size?’, fear not; there’s a tonne of ways to get an accurate measurement of your ring size from the comfort of your couch.

1. Use dental floss 

One hack is to use a piece of string or dental floss to get the circumference of your finger. Use the string or floss by wrapping it around your finger once, and then marking the point of overlap with a pen. Set the string against a ruler to measure the length, and voila! You now have the length in millimetres. With standard ring sizes, every half-size matches up to a 0.4-millimetre increment, starting with size 3 equaling 14 mm, size 3.5 equal to 14.4 mm, size 4 equal to 14.8 mm, and so on. You can then use the ring size chart on our website to get the letter size. When using this method, just make sure the floss or string doesn’t stretch - as it could give you the wrong measurement.

2. Use a current ring

You can also place a ring you already own in a size chart, which is an excellent alternative if you’re out engagement ring hunting! A foolproof and sneaky way to find accuracy.

3. Use a ring sizer

An easy way to measure your ring size is to use a ring sizer, like the ones available here at Shiels! With distinct markings and clear instructions, this makes it simple to find your ring size.

4. Consider the band thickness 

Always keep in mind that your ring size will be larger or fuller for a ring that has a thicker band, compared to a thinner one.

5. Measure at the right time

A good general tip is to ensure that you check and re-check the measurement a couple of times, because quite often, the fingers can become wider or narrower due to simple things like the weather, heat, cold, or perhaps even water retention or fluctuation in weight. 

The ideal time to measure your ring size is in the late afternoon, this usually gives the most correct size. Don’t measure your ring size when you’ve just woken up, taken a shower or just did a workout,  wait a little bit and then measure your size. It’s also important to skip assumptions like fingers on your right and left hand both having the same measurements, because it is far more likely that they don’t.

There’s more to our jewellery size guide than ring sizing. No one wants to buy a necklace without being able to correctly visualise how it’s going to fit, especially with respect to its length. While some pieces like the Cream Freshwater Pearl Oval Bar & Ball Necklace (Figure C) are meant to be a little more fitted, necklaces like the 9ct Yellow Gold Zirconia 5mm Solitaire Pendant on 45cm Chain (Figure D) or 14ct Yellow Gold Mixed Colour Freshwater Pearl 45cm Necklace (Figure E) have a style that requires s them to be lower-hanging. So, keep an eye out for the length of the chain of the necklace you’re interested in, this will give you an approximation of where, exactly, it will lie.


This one is the easiest! Simply use a measuring tape to loop around your wrist like a watch, and then adjust as per the perfect fit and length you’re looking for. Quick and easy, isn’t it? And here’s a pro-tip: while ordering your bracelet, if you’re uncertain about the fit of a piece, - a bangle vs a charm bracelet, for example - always opt for a looser option, as opposed to a tighter one.

This one is the easiest, and much like measuring the sleeves of a dress, this, too, can be done by simply using a measuring tape to loop around your wrist like a watch, and adjust as per the fit and length you’re looking for. Quick and easy, isn’t it? And here’s a pro-tip: while ordering your bracelet, if you’re uncertain about the fit of a piece, like in case of the difference in fit between a bangle and a charm bracelet, always opt for a looser option, as opposed to a tighter one.
