Finding the perfect ring can be an exciting experience. But before you get swept away by sparkling diamonds or shimmering gemstones, there's a step you need to complete: determining your ring size. Whether treating yourself or surprising a loved one with an engagement ring in popular styles, a ring sizing guide will be your best friend throughout this process.
In this ring sizing guide, we'll explore tried and tested methods to get an accurate measurement and discuss factors that might affect ring sizes.
Why Getting Your Ring Size Right Matters
A ring that's too tight will be uncomfortable and might even restrict blood flow. A ring that's too loose, risks slipping off your finger without you even noticing. Either way, an ill-fitting ring is not just an inconvenience - it could also mean losing a cherished piece of jewellery. Accurate ring sizing ensures your ring fits comfortably, letting you flaunt it with confidence and peace of mind.
Ring sizes aren't one size fits all. This means a size 6 in the UK won't be a size 6 in other parts of the world, such as the US or Europe. Be sure to use a ring size chart that clarifies the region's units of measurement to prevent any size discrepancies.
For example, if you're looking for information about a specific type of ring, like a gold ring, you might want to search for a "gold ring size chart UK" to get more targeted results.
In the UK, the ring sizes by circumference are generally as follows:
- Size I: 47.25mm
- Size J-K: 48.38mm
- Size L: 50.58mm
- Size M-N: 53.16mm
- Size N ½: 54.45mm
- Size O-P: 55.76mm
- Size Q: 57.15mm
- Size R-S: 58.47mm
- Size T: 61.52mm
Alternatively you can also measure by diameter. Take a look at our ring size guide instructional page for more details.
Factors That Can Affect Ring Size
Various factors can affect a person's ring size. Here are a few things that can affect your or your partner's ring size so you can choose the perfect engagement ring.
Time of Day
Did you know your fingers fluctuate in size throughout the day? This is because they tend to swell a bit in the heat and shrink in colder temperatures. For the most accurate ring size, it is advisable to measure your finger at room temperature.
Activity Level
Engaging in physical activities, especially those that involve your hands, can also cause your fingers to swell temporarily. It's best to measure your finger when it's at its normal size, typically in the morning.
Pregnancy
Pregnancy often leads to water retention, which can affect finger size. It's common for pregnant women to experience a change in ring size, and this change can sometimes be permanent. If you are pregnant, you might need to get your ring resized after delivery.
Methods for Determining Your Ring Size
There are a few different methods to find your ring size. Each method comes with its pros and cons:
Printable Ring Sizers
One option for finding your ring size is by using a printable ring sizer. You can download and print a ring sizing guide, just make sure your printer settings are set to 100% scale.
After cutting out the ring sizer, wrap the marked end around your finger, and the number it aligns with indicates your size. However, remember this method is highly dependent on accurate printing and might not be completely foolproof.
DIY Ring Sizing Method
You can use a piece of string, a piece of paper, or a flexible measuring tape to measure the circumference of your finger. Then, use a sizing chart to match the measurement to the corresponding ring size.
Measuring an Existing Ring
This method requires a ring that already fits you comfortably. Grab a ruler with millimeter markings, and measure the inner diameter of the ring - the distance across the centre of the circle. Note down the measurement and use a conversion chart (readily available online) that matches the diameter to its corresponding ring size.
Ring Sizing Apps
There are smartphone apps available that use augmented reality or virtual ring sizing tools to help you measure your ring size. These apps typically guide you through the process of finding your ring size using your phone camera.
While some apps claim to measure ring size, their accuracy is debatable. They might give you a general idea, but may not provide the most accurate fit.
Jeweller Sizing
Consider visiting a professional jeweller if you're not confident about measuring at home or want absolute certainty. Jewellers use specialised tools, ensuring a highly accurate measurement. It's particularly useful for those with larger knuckles or if you're purchasing an expensive ring, like a diamond ring, and want to minimise the risk of needing to get it resized later.
How to Measure Ring Size Without Your Partner Knowing
If you're planning a surprise and want to measure your partner's ring size without them knowing, here are some discreet methods you can use:
Borrow Their Ring
While they are not around, borrow a ring that they normally wear on the finger you want to measure. Make sure it fits comfortably on your finger and take note of how far down the ring slides. You can then visit a jeweler or use a ring sizing guide to determine the size.
Trace the Inside
Place one of their rings on a piece of paper and carefully trace the inside circumference with a pencil. Be sure to keep the ring flat and steady while tracing. You can then use a ring sizing chart to find their ring size.
Use a String or Paper
Take a piece of string or a thin strip of paper and wrap it gently around the finger where the ring will be worn. Mark the point where the end of the string or paper overlaps and measure the length with a ruler. Use a ring sizing chart or online ring sizer to convert the measurement into their ring size.
Compare Finger Sizes
If you have the opportunity to try on their rings briefly, you can compare the fit on your fingers. Pay attention to which of your fingers the ring fits comfortably on and remember the feel. This can help you estimate their ring size.
Enlist Their Friends or Family
If you feel comfortable doing so, you can discreetly ask their close friends or family members if they have an idea of their ring size. They may have discussed it or been involved in previous ring purchases.
Tips for Accurate Measurement at Home
Whether you are using a printable ring sizer or measuring an existing ring, here are a few handy tips to help you get accurate results:
Consider Your Knuckle
If you know you have a larger knuckle, it's best to size up slightly to ensure the ring slides over it comfortably. Try sizing up about half a size larger than what you measure at the base of your finger. This helps to make sure the ring can be taken off and put on with ease.
Measure Multiple Times
It's easy to be off by a fraction of a millimetre. To minimise errors, measure your ring size at least 3 to 4 times, ideally throughout the day when your fingers are at their normal size. Take an average of the measurements for the most accurate ring size.
Factor in Ring Width
Generally, wider rings fit more snugly than thinner ones. Make sure to factor this into account, especially if you're planning to buy a wide band. Consider trying on rings of different widths at a jewellery store to get a feel for how they fit.
