1) The only truly reliable method is to visit any jewelry store and ask them to measure your finger. All stores offer this service for free. It's important to ask for a special metal ring sizer in the form of rings, as trying on display rings often leads to errors!
2) If you're ordering a ring as a gift or for a proposal, and you want to keep it a surprise, the easiest way is to ask the person's friends or acquaintances (they often know the exact size).
3) If that's not possible, you can wrap a thread around the finger and measure the inner diameter of the resulting circle – that will be the ring size. But this method is very unreliable and often leads to errors.
4) If you have a ring that is worn on the same finger, there are two ways:
- Take the ring to a jewelry store or jeweler to have them measure the exact size (this is a fairly reliable method). You can also bring the ring to our client office (the most accurate method).
- Or, measure the inner diameter of the ring with a caliper/ruler – this will be the ring size, rounded to the nearest 0.5 mm (unfortunately, there won't be much precision in this case):
