Getting Your Correct Ring Size

Choosing the right fit can be tricky. It’s not always possible to try on a ring, and even if you have one that fits you perfectly already, it may not be the right style for your new bling. So how do you get the correct ring size?

Knowing Your Ring Size

If you’re shopping for a ring, for example men’s wedding rings, chances are you’ve come across the term “ring size.” But what does that mean? Are ring sizes universal? Do they change as we get older? Can we change our own ring size if it’s not right?

Well, let’s start by explaining what ring size is. It’s actually measured in millimeters (mm) and refers to the diameter of your finger at its widest point. As such, it doesn’t necessarily correspond with your actual finger measurements—and this can be quite confusing.

How to measure your ring size

Ring sizes can be tricky as there are many ways to measure ones ring size.

Here are a few ways to determine your perfect ring size:

1) Going to a jewelry store where a professional can help determine your size. This is the safest way of measuring your ring size.

2) Use a ruler to measure the diameter of an existing ring that fits you. This is not the safest way to measure if you are ordering an expensive wedding ring that can not be exchanged as 1mm makes a big difference when it comes to ring sizes.

3) Using paper or a string to measure the circumference of your finger. This is definitely an option but once again not very accurate as it is difficult to know how tight a comfort fit will be when using string or paper.

Ring Sizes in South Africa?

Ring sizes are Universal and are just labelled differently in different countries. For instance America uses numerical numbers such as 6, 7, 8 etc where as South Africa use alphabetical letters such as L, N, P etc.

South African ring sizes are measured in Alphabetical letters such as size P, R, U, V etc. For every letter shift upwards / bigger is equivalent to a half an american size increase in numerical numbers. For instance a size U (South African) = size 10 (American) and a size V (South African) = Size 10.5 (American).

Here are a few examples of South African Ring sizes with it’s respective diameter measurements:

Size P = 18.2mm

Size R1/2 = 18.9mm

Size U = 19.8mm

Size W = 20.6mm

Size Y = 21.3mm

Size Z + 1 = 22.2mm

Just a fun fact, the most common size in South Africa is a size U.

Get the Right Fit

  • If a ring is too big, it may slip off your finger.

  • If a ring is too small, you may feel discomfort or even pain.

  • The correct fit should allow 1/4 inch of space between the ring and your finger.

  • The ring shouldn’t be able to slide over the knuckle or down your finger when you flex it upward toward your hand.

Getting the right ring size when you can’t try it on is important.

You want to do this for two reasons: first, if you get one that’s too big or too small, your finger and hand will swell up in certain conditions (like summer heat), which could make a too-tight ring very uncomfortable. And second, if you’re going to spend a lot of money on a diamond engagement ring, getting the correct size is important!

If you haven’t been sized recently (maybe your last engagement was back when The Notebook came out) then finding a reputable jeweler is key. Once they have measured your finger properly and confirmed what size ring fits best, take some time at home to try out different rings in that size range until you find one that feels right.
