Buying a ring can sometimes feel slightly confusing especially if you don’t know what your finger size is. So, using our finger size chart below, this displays sizes in both metric and imperial for the most recognised international standards. This guide has been compiled from many sources in various countries to help you determine your local ring size, this will allow you to easily find your correct size or provide an accurate finger size measurement.
If the mandrel and plastic ring sizer seem like overkill, try our printable “Ring sizer”, “Paper strip ring sizer” or use the “International ring size conversion chart” below.

- This ring size method is based on the inside diameter measurement of a ring. Place the ring over the circles, lining up the inside edges of the ring to the circle that best matches on the ring size chart. If the ring is in between two sizes, choose the larger ring size.
Printable paper strip ring sizer
- This ring size method uses a tape measure approach with specific ring sizes. Cut out the paper strip ring sizer and open the slot where marked, with the letters facing out, slip the tip of the ring sizer through the slot. Place the sizer on your ring finger and carefully pull taut to read the finger size.

Traditionally, rings have been flat on the interior side and are referred to as "Flat / Standard Fit". There are many different shank profiles in the jewellery industry with the next most common being "Comfort fit" which is rounded on the inside. Comfort fit rings have become popular because they are, as the name implies, more "comfortable" to wear.
Comfort fit rings tend to "run big" and fit a bit looser compared to standard fit rings "of the same ring size" because of the different inner shapes. When the interior is round (comfort fit), there's less material in contact with the finger, which means less surface area in contact with the finger, which means it will feel looser. When the interior is flat (standard fit), there is more surface area in contact with the skin and it will feel tighter.
Again, this is comparing for the same size ring (same inside diameter).
It's worth reiterating: the same size ring in comfort fit may not feel the same in flat / standard fit. Comfort fit tends to feel looser.
* Note: A comfort fit ring can't really "run big" because a size is a size. The inner diameter measurement dictates the size. If it "ran big," it would just be a different size! With the International ring size conversion chart above we have taken the measurements for the Flat / Standard Fit ring to get the most accurate measurement for your finger size.
Try these ring sizing tricks of the trade to find the perfect fit.
- Go for a snug fit. As jewellers, we always say the ring should “go on easy, come off hard”. This means you have the right fit and the ring is sized properly for the finger, minimizing the risk of loss.
- Keep seasons in mind. Your fingers tend to change size throughout the course of the year, especially during summer and winter. They'll swell up a bit during the summer so keep that in mind so the ring doesn't become uncomfortable to wear during those months.
- Consider the width of the band. "The wider the band, the tighter it will fit", we recommend going up .25 to .5 size for rings with wider styles.
- Warm up your hands. If you've just come in from the cold or naturally have colder hands, we recommend warming them to room temperature for the most accurate ring sizing.
- Go BIG. If you get two different finger measurements or find that a ring you wear often fits differently from time to time, it's best to choose a slightly larger ring size, and, if you can, consult a jeweller.
