Found the perfect PUNCTUM ring, but you are not sure what size to order? Hereby you will find some indicative suggestions to find your accurate ring size.  The ring size chart below should tell you how many millimetres the size based on indicative country ‘s sizing system, as well as what ring size that measurement correlates to.

If you want to find your accurate ring size, please look the following! Remember to measure your fingers at the end of the day when your fingers are warm. Note that cold weather can shrink your fingers up to half a size, so make sure they are warm. Finally, alcohol and salt can make your fingers swell, therefore we suggest that you avoid measuring them after drinking alcohol and appetizers. The right fit should slide over the knuckle with a little friction and sit comfortably on the finger. The ring should not pinch your skin or make you feel like the circulation is being restricted to your fingers. It also should not be so loose on your finger that the ring can easily spin around.

A ring with a wide band such will need to be slightly larger than your normal size as wider bands will feel tighter than narrower bands. We recommend choosing a slight size larger than your normal size. For example, if you usually wear a size 8 (U.S.) for a narrow band, you should choose a size 8.5 (U.S.) for a wide band. So please keep this in mind when choosing your size!

There are two ways for you to find your accurate ring size:

  1. VISIT LOCAL JEWELLERS AND GET SIZED

Visit a local jewellery shop and ask to measure your finger, ideally using a calliper or micrometre. Measuring with a mandrel may result in less accurate sizing because not all mandrels are manufactured the same.

  1. MEASURE AN EXISTING RING

If you are fortunate to have an existing ring, you can bring this ring to a jeweller to use a calliper to measure the inside diameter of it in millimetres. This measurement can be used along with our Ring Sizing Conversion Chart (located at the very bottom of the page) to determine your ring size. This is considered a more accurate way to obtain estimated size.

 Do not forget to measure your knuckles as you may need to size up to fit rings over them.

We strongly recommend avoiding using string or paper to measure ring size as these materials can stretch or twist, yielding an inaccurate measurement.!
