How to Measure Ring Size

Measuring ring size is an important step when purchasing or ordering a ring. There are several methods for measuring ring size. One of the most common methods is using a measuring tape or ruler. The inner diameter of the ring is measured in millimeters or inches. Another option is to use ring sizers or sizing rings. A ring or sizing ring that fits comfortably on the finger is selected and checked for fit. Additionally, you can use a size guide, which you can find at the end of the article and even download it.

In What Units Can Ring Size Be Specified?

Ring size can be specified in various units. The most commonly used units are millimeters (mm) and fractions of an inch (often in the form of tenths or twentieths of an inch). Millimeters are a precise and widely used measurement system for ring sizes. However, in some countries, especially in the United States and the United Kingdom, ring sizes may be specified in fractions of an inch (for example, 6/8 inch or 0.75 inch). As a European brand, we measure sizes in millimeters.

Ring Size Chart

There is also a simple formula for calculating ring size from the circumference of your finger:

ring size = finger circumference in mm - 40

If your finger circumference is 60 mm, then according to the table of jewelry below, you should wear a size 20 ring. This method works for average finger sizes.

How to Make the Right Choice Between Two Ring Sizes, What to Choose?

Making the right choice between two ring sizes can be complex. If you find yourself in such a situation, it is recommended to consider several factors:

  1. Consider that fingers may change size depending on the time of day, temperature, and other factors, so one size may be more comfortable during the day.
  2. We consider the width of the ring itself - wider rings may feel tighter.
  3. The recipient's preferences for the ring - some people prefer a snug fit, while others prefer a looser fit. If possible, try both sizes and consult a jeweler.

Rings with Engraving

Rings with engraving are a special type of rings where personalized text or an image is applied. Engraving can be done on the inner or outer side of the ring. When ordering a ring with engraving, it is necessary to consider that it may affect its size. Engraving can take up a certain space on the inner side of the ring, so it may be necessary to increase its size.

How Long Does It Take to Resize a Ring?

The time required to resize a ring can vary depending on various factors such as the workload of the jeweler's workshop, the complexity of the resizing process, and the availability of necessary materials. Typically, the process of resizing a ring takes several days to several weeks. In some cases, especially if the resizing is complicated or requires special expertise, it may take up to three weeks.

How to Determine the Right Size

Determining the right ring size is important to ensure comfortable wearing and a perfect fit. The best way to determine the correct size is to visit a jewelry store where professionals can assist you. They may use special tools to measure the size of your finger. You can also use measuring tapes or sizing rings to roughly determine the size yourself. Below, you will find a size guide from Omara, which will help you make the right choice easily and flawlessly.
