You’ve got the ring size chart, but how do you measure your finger the right way? We teach you the simple procedure right below:

How to measure your ring size?

Get some string
You need a piece of string or thread for this method. You could also use floss if you haven’t got the string.

Wrap it around the finger
You should wrap it around the finger you want to wear it on. The string shouldn’t be too tight or loose, or the size will be affected.

Mark with a pen
Use a pen to mark where the string starts to overlap. This will be used to match the size chart.

Measure the string
Now lay down the piece of string next to a ruler or a measuring tape. See how many inches or centimeters the marked piece of string is.

Convert to millimeters
Make sure to get the size in millimeters or convert accordingly. This will help maintain accuracy.

Use a chart
Now that you have the exact measurements look at our size chart. See which millimeter or inch fit best. That’s the one for you!

Another way you can get your size is to find the size of the bling you already own. If this particular one fits you perfectly, you can go ahead and measure it with a string or place it on a size chart with markings for accuracy.

So then, what’s the best sizer for you?

It’s this adjustable and reusable little sizer tool. Use it on any finger and adjust it like a measuring tape every time. We recommend this instead of huge physical sizers that are super bulky with the weight of several rings and unnecessary most of the time.

The best part is that it’s portable. You can use it to measure toe and finger rings for adults and children to find the circumference!

Silicone spiral

Another alternative you have in adjusters is a long spiral that is spun around the base of the rings and makes the fit tighter. You could also have a go at the straight adjuster instead of the spiral. This simple clip-on must be measured and worn in the right size.

However, the spiral can be cut and twisted around the base in your preferred length and size. Both options are anti-scratch and easy to use with superior results.

A fold-over latch

There are more than plenty of resizing options in the market, and a fold-over latch is another innovative one.

A latch is for you if you don’t like squeezing your finger through rings after you get out of the pool, or come back from the gym or finish with the dishes.

It features a simple hinged latch at the bottom of the ring. When you put it on, keep the latch open. After putting it on, close the latch and go about your day. These are super comfy and very practical for fitness freaks and working professionals.

Ring guard

These are resizing as well as protection tools. They also enhance the look of solitaire rings. It consists of a small band on one or both sides of the solitaire ring. The choice of metal and the shape is entirely customizable.

Sometimes your rings will get tighter or looser, and the solitaire will flip to one side due to the weight. Guards are great to keep them propped up when this happens.

Do it yourself

While it is considered best not to mix foreign substances with your skin, some DIY resizing alternatives may be harmless. For instance, you can get some yarn or thread and wrap it several times around the base of your ring. Keep checking by sticking your finger inside and seeing whether it fits. Cut off the thread and tie the loose end together when it fits.

Try not to use any striking colored threads that will look funny with the ring. Use thread or yarn without any synthetic coloring to avoid allergic reactions.

Pro tip: While this is a quick fix, it is not permanent. Over time the thread will thin out, and the ring will become loose again. The knot may even come loose. You can either repeat the process or go for other more durable options like plastic, metal, or silicon adjusters.
