To measure ring size
How can you determine your ring size.
Ring sizes are displayed in different ways. Some brands choose the inner diameter in millimeters to use as size. Other brands choose to the outsite perimeter to handle as a measure. Sometimes also the US ring size is used. In itself it is not difficult, but sometimes a bit confusing. By-Sas uses the inside diameter of a ring, because this is the easiest way to measure it yourselfs.
Below you will find a size chart for ring sizes. Left is a list with inside diameters in millimetres. Right is a list of circumference sizes of fingers. If you know the circumference size of the finger, then you can look up the diameter size to its left.

METHOD 1: Measureing with a ring
The easiest way to determine a ring size is with a ring that fits you well and nice. This way is also handy if you, for example, want to surprise someone with a ring and you don’t want to ask for his or her size. You can than simply ' borrow ' the ring to measure.
Take your favorite ring and place it on a ruler. Make sure that one site of the inside of the ring is placed on the 0 cm and read on the other inside the number of millimeters. This is the ringsize of the inside diameter. In the chart you can look up your size.
METHOD 2: measure the circumference of the finger
If an appropriate ring is not available, then you can estimate the diameter of the ring the best by using a Ribbon or string.
lay the piece of string or ribbon around your finger where the ring at is going to be carried (but make sure that the string still have the thickest part of your finger) and cut it off where the string comes together. lay the string along a ruler. The length of the string is the circumference of your finger. in the chart above you can find on the right the circumference of fingers and on the left in the same line you’ll see your ringsize.
You can also cut a slip of paper for this method instead of ribbon. You can simply sign off with a pen. Measure the length along a ruler.
METHOD 3: use a flexible measure tape
It is an easy and fast way to measure. The flexible measuring tape is wider than a string, so you have a larger surface of the finger. Proceed as follows: wrap the flexible measuring tape around the finger and read the number of millimeters off there where the tape comes together. The length that you have now, is the circumference of your finger. At the chart above you will find your matching ring size.
Other ways to measure
You can also use a caliper to measure the inside diameter of a ring, or you can go to a jeweler for measuring your ring size. We assume that if you have a caliper, you also know how to use it for measuring ring sizes.
