Finding the perfect ring is an exciting endeavour, but making sure it fits comfortably is just as essential. Knowing your ring size is vital whether you're planning a surprise proposal or purchasing a new accessory. Here's a quick way to estimate your ring size:
The Paper Method
1. Gather Your Materials
To begin, you will need a thin, straight sheet of paper, a pen, and a ruler. Make sure that the paper is no wider than the ring you would like to wear.
2. Wrap and label
Wrap the strip of paper around the base of the finger to be measured. You want the ring to slide on comfortably, so make it snug but not too tight. Once it's securely wrapped around, draw a straight line down the centre of the paper where the two ends meet.
3. Determine the Distance
Remove the paper from your finger with care and lay it flat. Now, using your ruler, measure the distance in millimetres between the two highlighted lines. This dimension relates to the size of your ring.

Using an app
Alternatively, you can use a reliable ring sizing app, such as "Ring Sizer" by Jason Withers.
Choose a Reference Ring
To begin, choose a ring that you currently own and that you know fits well on the finger you intend to wear it on. This reference ring helps you in precisely determining your ring size.
Using the App
Download Jason Withers' "Ring Sizer" app for your smartphone. To use the app's augmented reality function, follow the instructions.
Circumference Matching
With the programme turned on, place your reference ring on the screen and align it with the virtual circle provided. Make the circle the same size as the circumference of your reference ring.
Determine Your Size
Based on the matched circumferences, the app will then suggest the ring size you require.
