The ring size comparison chart above includes ring sizes for both men and women. As you might expect, the ring sizes for men are a little larger, usually starting at EU size 52 (US 6), with 50% of men’s ring sizes falling between EU/DK size 60 (US 9) and EU/DK size 65 (US 11).
Follow this video guide which will guide you step-by-step to find your ring size.
Step 1: Measure your finger by wrapping a strip of paper or wide thread around it, leaving enough space to slide the ring over your knuckle.
Step 2: Mark the place where the paper strip meets and measure the length by using a ruler.
This is the circumference of your finger, which corresponds to European ring sizing. E.g. if it measures 5.4 cm you should choose a size 54. If you fall in between sizes, we recommend that you choose the larger size.
As a rule of thumb, you can always remember that you will probably need a slightly bigger size if the ring is wide versus slim. If the ring is sleek and slim we recommend that you opt for a slightly smaller size, e.g. 0.5 size difference.
This method can be used to find the ring size of any of your fingers.
Please note that the ring size can vary depending on the ring design and fit on your finger.
Measure one of your own rings using a ruler. Lay the ring on a flat surface and place a ruler on top of the ring. Measure the ring (inside diameter) at the widest part of the ring. When it comes to selecting the perfect ring size, precision is key, as even a few millimetres can make a difference.
Now that you’ve found the right size, discover rings crafted to fit beautifully.
Before you measure, get acquainted with your fingers
The fingers on your dominant hand tend to be larger than those on your non-dominant hand, so keep that in mind when measuring for your ring size.
Cold weather can cause your fingers to shrink a bit, while heat or water retention caused by food or medications can cause finger swelling.
Ring sizing tips
Here are a couple of tips on choosing ring size based on the ring’s design/style.
Large statement/cocktail rings: Keep in mind that broad/thicker ring bands (larger than 6mm) will fit tighter. It is better to choose half a size up when purchasing a thicker band, for the ring to be comfortable.
Stacking rings: When you buy slim stackers, ensure a comfortable fit by picking a snug-fitting ring size (measure the finger you choose to wear the ring on).
Types of rings
Rings have been the favoured accessory among both men and women for centuries. Accordingly, The Jewellery Room has curated an extensive range of ring styles and designs to accommodate the whim and fancy of every wearer!
Cocktail rings make a bold impression worn on any finger. Get measured for the finger you plan to wear the ring on.
Stacking rings are delightful companion rings that can be paired with your favourite gemstone rings or simply worn on their own! Create a playful look with a multi-coloured zircon- or diamond-studded ring party on as many fingers as you like.
Knuckle rings are trendy, hot, and all the rage. Pick half-a-size up and note designer-specific sizing instructions when you buy one of these.
Engagement & wedding rings are stunning and resplendent. Whether a solitaire or a gemstone-set band, these forever rings need to be chosen with careful consideration. Get the right size and you are on cloud nine every day!
Adjustable/open rings usually have a 3-6mm open end. These rings are great for gifting. Follow the designer’s sizing instructions and you are good to go.

Wrap a small strip of paper around your finger and mark where the ends meet. Measure that length with a ruler in millimetres to determine your European size. Alternatively, you can measure the internal diameter of a ring you already own.
Your size is based on the circumference of your finger in millimetres. If your measurement falls between two options on our chart, it is best to select the larger size. Keep in mind that wider bands often require a slightly bigger fit than thin ones.
Our Ring Size Guide comparison chart displays the inner diameter and circumference alongside various international scales. You can find your regional size by matching your measurement in millimetres to the corresponding US, UK, or DK/EU column. This gives you a way to understand global ring sizing language.
A well-fitting ring slides over the knuckle with slight resistance but stays securely on the finger. It should feel snug enough to not rotate or fall off during daily tasks. Be aware that your fingers may swell in the heat or shrink in the cold, affecting the fit.
Most men wear sizes between EU 60 and 65, though sizes often start from EU 52. While women’s sizes are generally smaller, the “average” varies significantly based on the specific finger and hand. Usually, your dominant hand will require a slightly larger size.
