How To Measure Your Ring Size?

The tool you use will determine the accuracy of your ring measurement, and there are both free and affordable options to make your life just a little easier.

Use a Free Ring Sizer

The easiest and most accurate method is to use one of our free ring sizers. They are really easy to use.

Then, when you’re ready you can simply email us the size you need and we’ll get your ring sent straight out to you.

Tips to get the correct size using a ring sizer

  1. Wrap the plastic ring sizer around the base of the finger you want to wear the ring on and make a note of the size. Try it at different times of the day.
  2. Then try it around your knuckle. You’ll want a snug fit here. Some people will find that they need a larger size than at the base of their finger (so the ring can go over their knuckle). Then just slide it down to make sure it’s still comfortable.
  3. You can also often get your finger measured for free at a jewelers. Although it’s worth noting that about 30% of time we’ve found they’ll give you the wrong size and you’ll end up exchanging your ring for a different size.

Measure Your Ring Size at Home

Or you could choose to use the tools that you have at home.

You are at a higher risk of miscalculating your size, so be careful and take a few measurements.

Common tools you can use are:

  • Thread
  • Floss
  • Measuring tool
  • Plastic strips
  • Ribbon
  • Twine
  • Paper

Tip: A good rule of thumb when using tools from home is to make sure they are made of non-stretchable material.

  1. Wrap the measuring material around the base of your finger/ close to your knuckle (specifically where you want to wear your ring) and mark it with ink.  With a plastic strip, you can wrap it around your finger, and tighten it (generally provides more accurate results).
  2. Then you can use a ruler to calculate the measurement. This is your ring circumference. Dividing this by 3.15 will get your diameter.

A ring size chart will then determine your size, according to the sizing your shop uses (numerical in US; alphabetic in UK/Europe).

Purchasing Ring Size Tools

You can also purchase specific tools to increase your accuracy. Ring-size tools are generally affordable and widely available online. The three best types are:

  • Finger gauge sizes and benders
  • Ring mandrels and sticks
  • Ring clamps

What Size is The Right Ring Size?

Remember that the thicker the band of your ring, the tighter the fit will be for your finger. Your fingers on your dominant hand are also larger, and if you can try the ring on, shake your hand. If it wobbles or moves a lot, it is too loose, but you should also be able to rotate it left and right comfortably.

What Size is The Right Size?

The most common size we sell is UK size S (both 6mm and 8mm widths are equally as popular) it’s then fairly split between sizes 8 – 10. After that larger sizes tend to be more popular than smaller ring sizes.

Does Weight/Height Affect The Ring Size?

Normally your height has very little relation when it comes to the size of your fingers. Just because you are on the shorter side else doesn’t mean you will have smaller fingers than someone taller, and vice versa.

But your weight and your finger size will have a little impact.  Your finger size can fluctuate with your weight.

When Should You Measure Your Fingers?

The size of your finger can actually differ slightly with changes in temperature. In order to get the best results, you will want to measure your fingers in the evening or the middle of the day, when temperatures are typically more stable.

Do not measure your finger when the weather is very hot or cold. Also, avoid taking any measurements while you are sick, just had a workout, or after consuming a lot of alcohol (by all means, propose then, just save your ring sizing til the next afternoon!)

What To Do With Inbetween Sizes?

If you are ever in doubt, always go up a size first. We can always exchange if we need to.

How To Figure Out Someone’s Ring Size Without Letting Them Know

It is a little tricky to figure out someone’s ring size without giving the game away!  If the person already has a ring, try to see if you can borrow that ring (or get a friend to borrow it) and take it to an existing jeweler to measure the ring size. Or you can work on measuring the diameter at home.

If the ring is flat, you can trace the circle of the ring on a piece of paper. Or you could also simply try asking family or friends.  Some of them might have tactics of finding out the answers without letting the intended person suspect a thing.

Otherwise, you can do a sneak attack, where they take it off to shower or sleep. Slip it on your own finger, and take note of where it stops. Or buy a bar of soap and turn it into a makeshift mould.

What Happens If You Get The Wrong Size?

If you get the wrong size, you might have to resize or replace it.  Depending on where you get the ring from, it can turn out to be expensive. Resizing often involves removing or adding in a small amount of metal. 

There are certain ring materials that cannot be resized, such as:

  • Resin
  • Jade
  • Wood
  • Ceramic
  • Tungsten
  • Eternity rings

With our rings, we offer 100-day free returns. So if you find out that you chose the wrong size,  we will have it exchanged for you completely free, no problem.

Once you have successfully measured your ring size once, it becomes easier to do it again. So measure your finger a couple of times, and always double-check the charts.

To measure your ring size at home, use a non-stretchable material like thread, floss, or paper strip. Wrap it around your finger, mark the overlap, and measure its length against a ruler. Divide the length by 3.14 to find the diameter, and use a ring size chart to find your size.

Finger size can vary throughout the day due to temperature changes and physical activity. It’s best to measure your finger size in the evening when your fingers are likely to be at their largest. Avoid measuring when your hands are cold, as fingers can be smaller, leading to an inaccurate size.

If your measurement falls between two sizes, it’s advisable to choose the larger size for comfort. A slightly larger ring is generally preferable to one that is too tight and difficult to remove. Remember, it’s easier to adjust a ring that’s slightly larger than to enlarge a smaller one.

To secretly determine someone else’s ring size, borrow a ring they already wear and measure its diameter, or make an impression of the ring in a soft material. Alternatively, enlist the help of their friends or family to find out their size without arousing suspicion.

If you choose the wrong ring size, many jewelers offer resizing services. However, some materials, like tungsten or ceramic, cannot be resized. Always check the return and exchange policies when purchasing a ring. If unsure, opt for a slightly larger size, as it’s easier to adjust down.
