Ring Size Guide and Chart - Free Ring Sizer

Your best option is to visit a jeweller in person. They can offer a fitting and advise on sizes using their knowledge of how each ring is made. For example, a thicker band on a ring means it will have a tighter fit than normal. You will likely have to go up a size.

You can also take a ring you already own and measure its inside circumference to get a general idea of what size you are looking for.

The average ring size for a woman in the UK is an L or M, which is an inside circumference between 51.2mm and 52.5mm. Predictably, it is larger for men and usually has an S or T, with an inside circumference between 60.2mm and 61.4mm.

If you decide to go to a jeweller in person, getting your ring size is normally completely free. An expert can advise you on the size and how this will vary in warmer weather when fingers swell and in the cold when fingers are slimmer. If you know what type of ring you are looking for, they can also advise if you need a larger size to accommodate a wider band.

Most jewellers offer downloadable sizers online. You can print the template and use it, but this is more of a rough estimate than if you go in-store. You can also buy professional ring sizers online, but it is always important to check this is a UK sizer.

If you do choose to measure at home, it is best to do so at the end of the day, when your finger will be at its largest. This will make sure you get the most comfortable fit.

Navigating your partners’ references and finding the perfect engagement ring can be challenging enough. But what if you also don’t know what ring finger size to buy? Don’t worry, here are some tips that will come in handy. The first thing you should do is always check your loved one’s jewellery box and use a ruler to measure the diameter of the rings they like to use on the middle finger of their left hand. You can also create a sketch using a piece of paper (just make sure you draw the inside and the outside of the ring to be sure of the circumference!) or a piece of string (if you’re careful you can even do this while your partner sleeps). If all else fails, there’s always the option to ask friends for advice. For example, you can ask someone who’s recently got engaged to let your spouse-to-be try the ring on. This should give you a good sense of possible sizes. And, if in doubt… always size up. It’s always easier to make your engagement ring smaller (rather than bigger) later.

Although getting the size right is important when it comes to a ring, this isn’t always a possibility (for example, if you’re buying a surprise engagement ring and you can’t figure out the correct dimensions in advance). However, we got some good news. Most jewellers can resize rings free of charge! Rings can definitely be altered. However, there are limitations depending on their design and materials. If a ring is too large, it can often be made smaller, and if it's too small, it can be made larger. Precious metals like gold and platinum are more malleable and can be resized more easily than harder materials like tungsten or titanium. The design of the ring also plays a role. Simple bands are easier to resize, while rings with intricate designs, gemstones, or engravings may be more challenging to alter without affecting their aesthetics. It's important to keep in mind, also, that engraved patterns may be lost, and certain designs may not allow for resizing without noticeable changes. Also, always have a professional jeweller handle the resizing process. They have the expertise and equipment needed to ensure the ring is resized correctly and safely.

There are a few factors that affect the cost of resizing a ring, including the type of metal, how complex the design is, how much you might need to resize it, and where you will have it done. Rings made of different metals will have different resizing costs. For example, resizing a gold or platinum ring is usually less expensive than resizing a ring made of harder materials like titanium or tungsten. The cost may also increase if the ring needs to be resized significantly (because making a ring much smaller or larger can require more time and materials). Rings with intricate designs, engravings, or multiple gemstones may require more work to resize, potentially raising the cost, too (and there might be additional costs if your ring contains gemstones as well). The good news, though? Many jewellers offer additional services such as cleaning and polishing the ring as part of the resizing process.

An engagement ring is a symbol of your love and commitment to each other. So, picking the perfect design is not something that should be done lightly. This also applies to size, as getting the right fit will determine the comfort of the ring. Now, finding out how big the ring needs to be can be rather complicated on its own, but you can figure it out by using other rings or measuring with paper or strings. The key considerations, though, have more to do with environment and activities, finger shape, and band width. For example, temperature, pregnancy, or diets can all impact a finger, so lifestyle plays a big role. Fingers can also vary a lot from person to person. For instance, if you have a tapered finger that widens towards the base, your rings might fall easily - so you would need a snug fit. Or, if you have big knuckles, you might need to add sizing beads to your ring. Lastly, thicker rings are usually tighter, so the same diameter might mean a different kind of fit depending on the width.
