How Do I Know My Ring Size?

Have you just snapped up a ring from our collection but you're not sure of your size? Don't panic, there are simple techniques for measuring your ring size at home without going to the jeweller's. Choose which hand and which finger you want to wear the ring on. The size of the fingers on the left and right hand may be different.

Measuring Your Finger

Step 1: Cut out the measuring tape

Carefully cut a ribbon or strip of paper. Make sure the strip is long enough to wrap around your finger.

Step 2: Wrap the tape

Make sure you draw a line on your measuring tool and then gently wrap it around your desired finger. Make sure your tool is snug but not too tight. It should slide easily over your finger without being too loose.

Step 3: Mark the joint

Make another line at the joint of your measuring tool.

Step 4: Note the distance

Using a ruler, measure the distance between the 2 lines to the nearest mm.

Step 5: Read the ring size

Use the table to note down the ring size corresponding to your measurement.

Perfect comfort for all sizes

We advise you to measure your finger early in the evening, as they tend to swell during the day depending on your activity and the ambient temperature.

It's best to take the time to measure your ring size so that you're wearing a ring that fits comfortably (neither too small nor too large), doesn't compress your finger and doesn't slip off your finger. This will also avoid possible exchanges and returns between you and the online shop. 

The shape and width of the ring will influence your choice of size: if the ring is wide and thick, it's advisable to choose a size larger; if it's ultra-thin, you should choose the size that fits your finger. If you're between two sizes, always go for the size above.
