Ring Size Chart for South Africa: How To Measure Your Ring Size

Navigating the intricacies of ring sizing can be daunting, especially when planning a surprise proposal. While the design, metal, and gemstone (lab grown or natural) are crucial, the ring's size is equally important for that perfect fit. This guide aims to demystify the process of determining ring sizes in South Africa, offering ingenious methods to discreetly determine your partner's size.

Ring sizing varies globally, adding an extra layer of complexity when shopping online. Unlike most countries that use numerical systems, South Africa and the UK employ an alphabetical approach. Each letter on the size chart in South Africa corresponds to a specific ring circumference. For instance, size 'A' signifies a 37.8mm circumference, while 'Z' stands for 69.1mm.

Important note: Size variations between jewellers

It's crucial to note that ring sizes can vary between jewellers, adding another layer of complexity to your decision-making process. The most reliable way to ascertain your ring size is to consult a jeweller for a professional fitting, especially since factors like ring thickness can affect the fit. Thicker rings, for example, tend to fit more snugly.

If an in-person fitting isn't feasible, particularly when shopping online, there are alternative methods to accurately gauge your ring size. Continue reading to discover how our complimentary downloadable ring sizer tool can assist you in this endeavour.

Understanding South African Ring Sizes

If you're considering buying a ring in South Africa, it's essential to grasp the country's unique sizing system.

How do South African ring sizes work?

South African ring sizes are determined by the finger's circumference and internal diameter, measured in millimetres. These measurements are denoted by alphabetical letters, each corresponding to a specific circumference and internal diameter range.

The sizing scale begins with the letter 'A' and ascends to 'Z,' extending further with sizes like Z+1, Z+2, and so on for larger dimensions. Half sizes are also accommodated, usually indicated as M1/2, signifying the ring size falls midway between M and N.

How are rings measured in South Africa?

In South Africa, ring sizes are gauged by measuring the finger's circumference where the ring will be worn. You can use a string or tape measure for this, recording the measurement in millimetres. Once you have the measurement, refer to a South African ring size chart to find the corresponding alphabetical size.

It's worth noting that ring sizes can fluctuate based on the ring's width and the shape of the finger. Therefore, trying on the ring for a more precise fit whenever possible is recommended. Following this method will aid you in selecting the right ring size, even if you can't try it on beforehand.

Measuring Your Ring Size at Home

Knowing your precise ring size is crucial for a comfortable fit when shopping for a ring online. Fortunately, you can easily measure your ring size at home using basic household items. Here's a straightforward guide to help you determine your ring size without stepping out of your front door.

Use a ring sizer or mandrel

Utilising a ring sizer or mandrel is one of the most reliable methods for determining your ring size at home. A ring sizer is a set of graduated rings designed to fit your finger, allowing you to easily identify your size. Simply slide the sizer onto your finger and adjust for a snug fit, noting the size indicated just above the ring. Alternatively, a mandrel—a cylindrical stainless steel tool marked with sizes—can also serve the purpose. If you have a ring that fits well, place it on the mandrel to find your size. If not, a string or thin strip of paper can be wrapped around your finger; mark the overlap point and then align it with the mandrel to ascertain your size. While both tools can be purchased online, a more cost-effective option is to use our downloadable ring sizer.

Different methods of sizing a ring


Use a string or strip of paper

If a ring sizer or mandrel isn't readily available, a simple piece of string or a paper strip can be a practical alternative. Wrap the string or paper around the base of your finger where the ring will sit, marking the point where the two ends meet. Measure this length in millimetres and consult a ring size chart to find your corresponding size. This method provides a straightforward way to ensure you select a ring that fits comfortably.

Use an existing ring

If you already own a ring that fits perfectly, you can use it as a reference to determine your ring size. Measure the ring's inside diameter in millimetres and consult a ring size chart to find your corresponding size.

A ruler can be a handy tool for this task. Some ring size charts even feature printed circles that match various ring sizes. You can easily identify your size by placing your existing ring over these circles. However, printing the chart to scale for accurate results is crucial. Keep in mind that the ring's thickness can also affect its fit. If you still need to decide, consulting a professional jeweller for precise sizing is always a good idea.

Getting His or Her Ring Without Knowing Their Size

Securing the perfect ring for your significant other is both thrilling and meaningful, especially if you're gearing up for a marriage proposal. Yet, the task becomes tricky when you need clarification on their ring size. Here are some discreet methods to determine their size to help you navigate this challenge without tipping your hand.

Option 1: Borrow one of their rings

A straightforward method to ascertain your partner's ring size is to momentarily take possession of one of their rings. Opt for a ring they typically wear on the relevant finger to ensure an accurate measurement.

You can then consult a jeweller for sizing and design recommendations. Exercise caution in your selection; avoid taking a ring of significant sentimental or monetary value that they frequently wear to prevent causing undue stress or concern.

Option 2: Ask a trusted friend or relative

If the idea of borrowing a ring doesn't sit well with you, consider seeking assistance from a trusted friend or family member. They might already be privy to your partner's ring size or could discreetly inquire without arousing any suspicion.

Option 3: Use a printable ring sizer

Take advantage of our complimentary printable ring sizer for a more hands-on approach. Simply print it, cut along the lines, and wrap it around your partner's finger to gauge the size accurately.

The challenge lies in crafting a convincing reason for needing this information. To keep your intentions under wraps, consider inquiring about their ring size around their birthday or your anniversary, casually suggesting that you're contemplating 'a ring as a special gift.'

Option 4: Go shopping for a friend or family member together

A cleverly orchestrated visit to a jewellery store can yield your partner's ring size without arousing suspicion. Pose as if you're shopping for a gift for someone else and ask your significant other to try on various pieces of jewellery, rings included.

This tactic helps you determine their ring size and offers valuable insights into their preferences in styles, designs, and gemstones.

However, ensure you pop the question before the supposed gift-giving occasion arrives. The last thing you want is for your partner to inquire about the 'gift' you never actually purchased.

Pro Tip: To minimise risk, pretend you're shopping for someone who isn't a mutual friend.

What Happens if I Choose the Incorrect Size?

Ensuring a perfect fit is crucial when buying a ring, but there are instances when the size may need to be corrected, necessitating adjustments. If you find yourself in this situation, don't panic.

Most jewellers offer resizing services to fine-tune the fit. Keep in mind that the feasibility of resizing often depends on the ring's design and material, so it's always a good idea to consult with your jeweller about the options available to you.

What happens when my ring is resized?

When your ring undergoes resizing, the jeweller typically alters the metal band to achieve the desired fit. If the ring needs to be downsized, a segment of the band is removed, and the ends are seamlessly fused together.

Conversely, if the ring needs enlarging, additional metal is incorporated into the band before the ends are joined. This meticulous process ensures that the ring maintains its original integrity while fitting your finger comfortably.

Adjusting a ring's size can have consequences for its structural durability. For instance, rings made from softer metals like gold may become more vulnerable to wear and tear following resizing.

Additionally, if the ring has intricate designs or embedded stones, resizing could compromise these elements. It's also worth noting that resizing often incurs an extra charge. Therefore, aiming for an accurate size from the outset is crucial to avoid these potential issues.

Additional Ring Sizing Tips

When selecting the ideal ring size, there are several nuanced factors to consider for a perfect fit. For instance, the band's width can influence how snugly the ring fits; wider bands generally fit more tightly. If you're uncertain, opting for a half-size larger for comfort is advisable.

Timing also matters. Finger width can fluctuate due to various factors like temperature, stress, and hydration levels.To get a more accurate size, measure your finger at different times throughout the day. It's best to avoid taking measurements immediately after exercise or during periods of hormonal changes, as these can cause temporary swelling.

Weight changes can also impact ring size. If you or your partner have experienced significant weight fluctuations, it's wise to re-measure your ring finger.

Seasonal changes can also affect finger size; fingers may swell in hot weather and contract in the cold. Therefore, consider the current weather when determining your size.

Lastly, while at-home measurements provide a good starting point, nothing beats the accuracy of trying on rings in person. This hands-on approach will give you a clearer sense of how different sizes fit and feel.
