With their roots dating back to ancient civilizations, rings have been symbols of tradition and social status for thousands of years.

Today, we often associate rings with commitment. Promise rings, engagement rings, and wedding bands are meaningful ways to mark milestones in romantic relationships. Regardless of the exact reason for why you’re looking to buy a ring, it is most likely a substantial financial commitment, and a purchase that you are hoping will last a lifetime.

With such a big decision, there are a lot of factors to consider — composition, settings, karats, clarity, etc. While many of these factors are elements of personal choice, one aspect that you do not have control over but must consider, is size.

How to Measure Ring Size at Home

You can easily determine your ring size at home by following a few simple steps.

Measure Your Finger

Going to the jeweler may be inconvenient due to time constrictions or distance. If you are in a situation where determining how to measure ring size online at home is your best option, we have some tips and tricks to help you out.

You can get an accurate gauge on ring size with just four everyday household items.

First, you will need to gather a long piece of string or paper, a tape measure or ruler, scissors, and a pen or pencil.

  1. If using paper, cut it so that it is long and thin.
  2. Wrap the string or small piece of paper below your knuckle and carefully cut it at the point where the ends begin to overlap.
  3. Lay the string or paper on a flat surface and measure the length in millimeters (mm).
  4. Use our sizing chart to determine your ring size depending on the country that you live in.

For example, if the length of your string measures at 57 mm, you are a size 8 in the US and a Swiss size 17.0.

Round up to the nearest number if you find that your measurements are in between increments.

Measure Another Ring

If there is already a ring at home that fits the exact finger that you are trying to size a new ring for, you can use the existing ring to help you out.

For this method, you will just need to measure the inside of the upper edge of the band to the inside of the lower portion of the ring. Once you get that number in millimeters, you can use the chart mentioned above to help you find the appropriate size.

Additional Tools

There are some other handy tools that you can use to ensure you are selecting a size that will get you the best fit possible. If you know someone who has a ring mandrel or a ring sizer set, you may want to consider borrowing those tools.

Sizing Tips

Fit of the Ring

The way that the ring is designed to fit will influence the size that is appropriate for you. The band you are looking at having sized may be “comfort fit” or “standard fit,” and will be an essential factor to consider.

Rings fall into the standard fit category when they are precisely the same size all throughout the inside.

Comfort fit rings, on the other hand, are rounded on the inside at the place that touches the skin. This style can be beneficial because it allows the ring to easily slide over the knuckle and create less friction because it covers less surface area of the skin.

If you have chosen a comfort fit ring, you will simply want to order a half-size smaller than the measurement that you have been given for a standard size ring.

Dominant Hand

Since wedding bands and engagement rings are often placed on the left hand, there are a couple of key pieces to keep in mind.

The dominant hand is usually larger than the other. If you are someone who is left-handed, this means that the fingers on your left hand will most likely be a little bit larger than the fingers on your right. So, even though you may know what size your ring finger is on your right hand, that does not necessarily mean you know what size you need for your left hand. Always measure!

Issues to Consider to Get a Good Fit

There are several things you’ll need to take into account in order to get the correct fit.

Your Finger Size Fluctuates

The size of your finger will vary by what time of day it is. Many people find that their fingers swell up while they are asleep for the night, and as the day goes by, it may become noticeable that your finger has shrunk down half of a ring size.

Your body temperature also affects your finger size. In warmer weather and after strenuous activity, you will probably find that your finger has swollen up.

It is best to measure in the middle of the day when you are relaxed and in a room with moderate temperature to obtain an accurate measurement of the diameter of your finger.

Width Matters

Expect wide rings to fit tighter on your finger. If you find that thick bands catch your attention the most, consider going up in size by .25 to .5. Keep in mind that if you are purchasing an engagement ring, a wedding band will also go on the same finger, so you will want to account for the additional width that will occur once both rings are on the finger.


Getting your ring size just right can be a tricky undertaking. If you find yourself stumbling upon some obstacles, there are a couple of things to keep in mind.

Keeping It a Secret

If you are planning to surprise your partner with a ring, figuring out what size to order can be difficult, but there are a few tips to keep in mind when faced with this situation.

If your partner already has a ring that goes on the finger you’re selecting a new band for, your job is fairly easy. Find a time when your partner isn’t wearing his or her current ring and use the simple measuring techniques that are listed above.

If it is easier for you to get ahold of a ring that goes on the same finger that you are looking to size, but on the opposite hand, keep in mind that whichever hand is dominant will measure a little bit larger.

If your partner doesn’t have a suitable ring for you to borrow for measuring, try asking a close family member or friend. There is a chance they may know what size you should order.

If you’re not able to obtain any of the information that you need to select the correct size, guess based on the norms. The average ring size for women is somewhere around 7, and the average ring size for men is 10.


Even though you may try your best to get the perfect fit, sometimes it just doesn’t work out. Luckily, re-sizing your ring is an option, but there are a few issues to consider before getting the size altered.

Re-sizing a ring causes a weak spot. When a ring is split apart and then put back together, the location where the ring got soldered will become less sturdy.

If the ring is designed to have a designated top and bottom portion, soldering happens at the bottom of the band. This can be an issue because the bottom of the ring is where pressure is exerted on it most. In cases of the ring encountering extreme weight, this may result in the band breaking.

Moral of the story: be sure to use a trusted professional whenever you are altering the size of a ring so that you decrease the risk of damage occurring.

We’ve provided you with some handy tips and tricks on how to measure your ring. The entire measurement process takes just a few minutes, and then you are on your way to ordering the ring of your dreams and preparing for the celebrations that will go along with it.
