How Do You Measure Ring Size?

If you’re wondering how to measure ring size, you’ve come to the right place! Getting the right ring size for an engagement ring is crucial for a perfect fit. Whether you're surprising your partner or picking out the ring together, accurately measuring the ring size is essential. 

In this guide, we'll explore different methods to measure your ring size, from visiting a jeweller for professional measurement to using printable size charts or the string method.

Guide: How to Measure A Ring

If you have an existing ring that fits well, you can measure its inner diameter or circumference using a ruler or a ring size chart to determine the size. 

Free ring size charts can be downloaded and printed online. Our very own ring size guide is available to download and print below! 


Ensure the chart is scaled correctly and follow the instructions provided. Place an existing ring on the chart to match the inner circumference with the corresponding size.

If you don’t have an existing ring, there are still ways to measure ring size by measuring your finger. Read on to find out how.

Guide: How to Measure Your Finger

To measure your finger for the right engagement ring size, you can use the following methods:

String or Paper Method

Wrap a thin strip of paper or string around the base of the intended finger. Mark the point where the string or paper overlaps and measure the length with a ruler. Refer to a ring size conversion chart to determine the size based on the measured length.

Professional Measurement

Visit a jeweller and have your finger professionally measured using a ring sizer. They will have a set of ring sizer tools to determine your exact ring size.

    Remember to measure multiple times and under different conditions (such as temperature) for accuracy. It's important to note that the ring size can vary slightly depending on the finger, so measure the specific finger you plan to wear the ring on.

    Jeweller's Tips for Measuring Ring Size

    Measure in the afternoon

    Fingers tend to be slightly larger in the afternoon or evening due to natural swelling. It's a good idea to measure during this time to ensure a comfortable fit throughout the day.

    Consider the width of the band

    Wider bands may require a slightly larger size for a comfortable fit. Keep this in mind when measuring if you plan to have a wider band for your engagement ring.

    Measure the specific finger

    Measure the exact finger you plan to wear the ring on, as ring sizes can vary between fingers.

    Seek professional assistance

    If you're unsure or want the most accurate measurement, visit a jeweller for professional ring sizing. They have the experience and tools to ensure precise measurements. If you’re from Melbourne, you can always book an appointment or visit our store for help with ring sizing!

    Measure multiple times

    To ensure accuracy, measure your finger multiple times using different methods and compare the results. This can help you find the most consistent measurement.

    Remember, it's better to have a slightly larger size that can be resized later than a ring that feels too tight. When in doubt, consult with a professional jeweller who can guide you through the process and offer expert advice.

    Ring Size Chart

    A ring size chart displays a range of ring sizes corresponding to specific measurements, such as inner circumference or diameter. It helps determine the appropriate ring size based on your measurement. By comparing the measurement of your finger to the chart, you can easily identify the corresponding ring size. This makes it convenient to find the right size when ordering a ring online or when you don't have access to a physical ring sizer.

    Can Rings Be Resized?

    Yes! Rings can often be resized. Resizing involves adjusting the size of the ring to make it smaller or larger to better fit the wearer's finger. It is a common service offered by jewellers and can be done for many types of rings, depending on the design and materials. 

    However, certain factors such as the ring's style, gemstones, and metal type can affect the feasibility and limitations of resizing. It's best to consult with a professional jeweller to determine if a ring can be resized and to ensure the resizing is done properly.

    Is It a Surprise?

    If you’re planning to surprise your partner with their dream ring, it can be challenging to get an accurate ring size measurement! Here are a few strategies you can try:

    1. Borrow a ring: If your partner already wears rings, discreetly borrow one that is worn on the intended finger and take it to a jeweller for sizing. Be sure to choose a ring that is frequently worn and fits well to get the most accurate measurement.

    2. Enlist help from friends or family: Reach out to a close friend or family member who may know your partner's ring size or can discreetly find out without raising suspicion.

    3. Use a ring sizer app: Some jewellery retailers offer mobile apps that use augmented reality or measurement algorithms to estimate ring size based on a photo of your partner's hand. While not as accurate as professional sizing, it can provide a rough estimate.
