Ready? Let’s Start!

Tools You Will Need

It is easy to measure your ring size at home; you don’t need too many specialized tools for it. Here are some things that you can use and will easily find at home: 

• A ring sizer; these are easy to come by. You will find both plastic and metal sizers online. 

Or

• You can also use an existing ring that fits you well to determine the exact ring size. 

Or

• A strip of paper or string to wrap around your finger and a ruler that will help you measure the paper or string’s length accurately. 

Methods to Measure Ring Size

Using a Ring Sizer

This is an accurate method to find your ring size. They come in two types: 

• Adjustable belt-style sizers: This is a flexible plastic strip that has markings for different sizes. 

• Individual ring gauge sizers: A set of metal or plastic rings that have different sizes. 

How to use a ring sizer: 

Step 1: Slide the adjustable ring sizer or different gauge rings on your finger. 

Step 2: Ensure that the fit is comfortable. Ideally, it should slide over the knuckle with no resistance. 

Step 3: Check the marked size on the sizer. 

Measuring an Existing Ring

You might have a ring that already fits, so use it to determine your size: 

• Start by placing the ring on a printed size chart that you will easily find online.

• Match its inner circumference to the closest size on the chart.

• Make sure that alignment is proper; misalignment will lead to inaccurate ring size. 

Using a String or Paper Strip

This simple DIY method is the best way to measure your ring size if you don’t have a ring sizer at home. Follow this step-by-step guide:

Step 1: Cut a thin strip of paper, or use a piece of string. 

Step 2: Wrap it around the base of your finger, and ensure it's comfortable but not too tight.

Step 3: Mark where the strip or string overlaps. 

Step 4: Lay it flat, and use a ruler to measure the length. This should be done in millimeters (mm). 

Step 5: Finally, compare the measurement to the US ring size guide we have provided below. 

Remember: Do not stretch the string when measuring against the ruler. It will give you incorrect numbers and lead to confusion. 

Factors Affecting Ring Size

There might be times when your finger size isn’t constant; some factors may cause it to change, and thus affect your ring size. Here are some ways you can get the correct measurement: 

• Temperature: Fingers can swell and shrink in the cold weather. 

• Cold temperatures can cause the fingers to shrink and result in an inaccurately small size.

• Heat, exercise, or water retention can make your finger swell, and lead to a larger size.

• The best practice is to measure your finger when it's at a normal temperature.

• Time of Day: Your finger size often changes during the day: 

• In the morning, they may be smaller after the night’s rest. 

• Fingers are slightly larger throughout the day due to swelling from your daily activities. 

• Do the ring size calculations in the evening, when fingers are large, but not too swollen. 

• Use Only Accurate Tools: 

• Materials like an elastic thread will stretch when you wrap it around your finger, which will lead to incorrect measurements, so avoid using it. 

• While paper strips will work, there is a chance they might crumble and lead to inconsistent results. 

• Use a sturdy strip of paper, a non-stretchable string and a printable ring size chart to get accurate measurements. 

• Make sure you measure the ring size close to the knuckle, to ensure that the ring will smoothly slide into your finger. 

• Keep in mind that wider bands feel tighter, so go up by half a size in case you are thinking of buying a thick ring. 

US Ring Size Chart and Conversion

Ring sizes are different in every region. In such a case, the question arises: ‘how to determine ring size accurately?’

Here is a detailed chart that will help you convert your ring size correctly: 

Since no single system is common in countries, having a ring-size conversion chart will be helpful. Online jewelers also provide tools where you can input one size and get its equivalent in another region. Remember to check the conversion chart at the store you are buying at, and measure in millimeters to find the closest match in case you are unsure.
