Is there such thing as normal finger size?

What is a large ring size for a woman

More often than not, you will find most people questioning what the ‘normal’ ring size for a man or woman is whenever they don’t really know the size of their finger.  

While it seems the right question to ask, there is no such thing as a ‘normal finger’ size for both genders. This is mostly because every human being is built differently and for this reason alone, our fingers can never be similar.

If you have noticed, some people you meet have long thin fingers, others have large knuckles, and others have short thin fingers. You may also come across others with short and wide fingers, or another group of people with long and slightly wide fingers. Based on this, ring sizes differ greatly.

Besides that, ring sizes also fluctuate depending on the hand that you measure. To explain this better, your dominant or most used hand is often larger than the less dominant one.

So, if you are a left handed person, your left hand is definitely larger than the right, and if you are right-handed, your right hand is slightly bigger than the left.  

In addition to that, temperature and body fluid somehow affects ring size. During the summer season, your hand gets bigger as it gets warmer outside, and you are bound to experience loose fittings during the winter season as it gets colder.

Also, your fingers are often smaller in the morning and slightly larger towards the afternoon. We also cannot forget to mention that your ring size fluctuates if you gain or lose weight. All these factors are normal, so there isn’t really anything like a ‘normal finger size’.

In that regard, what you need to know about is the average ring size for every man and woman and the typical range of sizes in different regions and jeweler stores, so that you can get the perfect fit. Aside from that, always try on different rings in order to find a comfortable fit for daily wear.

Alternative Three: Purchase a ring sizer

A ring sizer is one of the most accurate tools that you can use to measure your ring size. Once you have purchased one, you should do the following;

  1. Put the ring sizer over your chosen finger and pull it tighter slowly until you have the correct size. The correct size is simply one that allows the ring sizer to move over your knuckle seamlessly.
  2. The measured size that you should be using in this case, is the one towards the inside of the ring sizer’s buckle. If the gauge shows a point between two sizes, you are better off using the larger size.
