DIY At Home – Ring Sizing Guide


A pandemic has not stopped people from giving each other jewelry, especially engagement rings. In fact, absence may have actually made many hearts grow fonder. But, when you cannot personally try on rings in a store setting with a professional sizing expert literally at your fingertips, don’t despair. There is a way to size those ring fingers at home with these helpful tips.

One fairly accurate way to measure for ring sizing at home is to use the string or thread technique. Simply wrap the string or thread around your finger and then hold it up against a ruler. Do this a few times to make sure you have an accurate measurement. Then, take the inner circumference numbers to get your ring size.

Don’t forget to account for the fact that your finger will naturally swell throughout the day. Allow some room and don’t get too tight of a fit. Measuring your ring finger in the mid-afternoon is going to give you the most accurate idea.

Sizing a ring is about more than simply slipping it on your finger and adding a sizer if it’s too large. There are other things to think about. For instance, many don’t consider the thickness of the band and how it will affect the way it fits.

Once you know how to measure the finger where the ring will rest, you will need to get a hold of a ring sizing chart that is specific to the country of origin for the ring you want to purchase. In the United States, sizing begins at a size 3 for a diameter of 14.1mm and gradually moves up to a size 13.5 at 22.6mm, which are comparable to the EU 44 to Z+2,  the UK & AU F ½, SGP & JP 4, HK 6, and CHE 4, all of which end at a smaller size than the US or EU do. Most women fall somewhere in the size 5 at 15.7mm, 6 at 16.5mm, or 7 at 17.3mm range, or an EU equivalent of 49 to 54.

Your knuckles and length of your finger are also going to be considerations for what style of ring you choose. Generally speaking, larger hands require larger jewelry, while smaller hands need more dainty rings. A thicker ring will be good on thicker knuckles, and big oval stones will work best with long, slender fingers. Small stones and delicate rings look nice on slender, slim fingers.

Ultimately, whatever ring style you choose, you will want to make sure it is a good fit and works well with your lifestyle. After all, especially if it is an engagement ring, you will want to wear it for years to come.
