Jewelry teaches you how to measure the inner diameter of a ring? How to measure the inner radius of the ring? Let me explain to you the jewelry below. Method 1: When measuring, put 4 long fingers (except the thumb) to the 'tiger's mouthSuitable for your circle mouth. This specification will have a certain pain when worn, please use hand sanitizer and other lubrication. Some people like to wear a little looser, they can choose a larger circle mouth. Method 2: When choosing a jade bracelet, you should be able to put the jade bracelet into the 4 long fingers (except the thumb) and reach the 'tiger's mouthFor example, it is exactly 55 mm, then this size is suitable for your ring mouth. Some people like to wear a little looser. When choosing, choose a circle with a size of 1 to 2 mm, so that it can be easily put on and removed. Some people are accustomed to wearing smaller jade bracelets, or don't plan to take them off again. In this way, the size can be reduced by 1 to 2 millimeters. Generally, when choosing, you should try it on first. When trying it on, put some detergent or soapy water on your hands and ask someone for help. Put the jade bracelet into your wrist with a little force. Method 3: Put your five fingers together, ask someone to use a soft rope to measure the circumference of the thickest part of your hand in the thinnest state, then divide by 3.14, and add 1~2mm to get the inner diameter of your ring. For example: the length you measured is 170mm, then 170/3.141~2u003d55~56mm. Warm reminder: The above three methods provided by Jewelry have their own shortcomings. You'd better try each method as much as possible, measure it several times and then calculate the average value, which is more accurate.
