Measuring finger size is important when picking out your ring. If you're not sure on your finger size, you could end up buying a piece of jewellery that is loose or too tight. Before measuring your finger, consider coming into our store in Birmingham Jewellery Quarter to have your finger sized by a professional.
Alternatively, to find out at home, read below.
Range of Sizes
Before starting on measuring, you will need to know the possible sizes. There are a total of 32 sizes on a standard measuring stick. For reference, most jewellers will use this range when measuring any ring. Some sizes will be extremely unlikely for the average person; these sizes will include the absolute smallest sizes (A–G) and the largest sizes (Z+2 to Z+6-beyond). As a reminder, these are not abnormal sizes. People's finger sizes will always be different.
It's best to know the possible sizes before entering a jewellery shop, as you will understand the sizes of in-the-counter items.
