With rings, it’s usually love at first sight, so you may want to place an order quickly, but they’re asking you to choose a ring size. You have no idea what it is. Or maybe you’re out ring shopping for your partner?
Getting the wrong ring size can dampen the proposal moment a bit. So, what do you do? How do you get it right the first time without the need for resizing? We’ll show you how to measure your ring size using simple methods.
How to Measure Your Ring Size in 4 Ways
You can measure your ring size right from home. Here are four simple methods you can try out.
Using a Ring Sizer
Ring sizers are usually made of stainless or plastic. They are both typically inexpensive and readily available. Some jewelry stores may offer to send a free ring sizer before making a purchase, or they may have a downloadable one you can print.
One type of ring sizer is a bunch of rings of different sizes looped together. You will need to try out each ring to see the one that fits best. Once you find it, check for the ring’s size code to find your ring size.
Another type of ring sizer, usually made of plastic, is designed like a belt. You wrap it around the intended ring finger to determine your ring size. Like the other type of sizer, it is graded according to ring size.
You can also download this type of ring sizer from some jewelry websites. It is sometimes called the paper ring sizer. Make sure to print it according to scale to ensure accurate measurement.
💡 Tip: If your ring size is between two numbers, it is always better to go for the larger size.
With a Ring You Own
If you already wear rings and have a ring that fits the intended finger, you can easily use it to measure your ring size. First, you can measure the diameter of the ring and compare it with a ring size chart. Simply measure the inner width of the ring using a ruler or a tape rule.
You can also download a true-to-size ring sizing chart. Place the ring on each size on the printed chart to find the one that fits.
💡 Remember: You should match the inner width of the ring, not the outer width.
Measuring Ring Size with a Tape Measure
This is another method of measuring ring size.
Materials Needed
- Tape measure
- Ring size chart
Instructions
- Place the measuring tape at the base of the intended ring finger.
- Wrap it around the ring finger.
- Gently move it up to the knuckle and down to check if it can pass through.
- Check the measurement at which the tape measure overlaps.
- Compare it with a ring size chart.
How to Measure Ring Size with a String
You can make your ring sizer with a string, dental floss, or even paper. It follows the same principle as the tape measure method.
Materials Needed
- String or dental floss or paper
- Pen
- Ruler
Instructions
- Wrap the string or dental floss around the base of the intended ring finger.
- Pull it up to the knuckle and then down. Make sure it feels snug but not too tight.
- Mark where the string ends meet with a pen or marker.
- Place it against a ruler and get the measurement in millimeters, centimeters, or inches.
- Compare your measurement against a ring size chart.
💡 Tip: Be careful with tugging on the string so you don’t make it slack and make your measurement inaccurate.

- Measure your finger three to four times to ensure accuracy.
- Consider the size of your knuckle when measuring. You can measure the width of your knuckle and base and choose a number in between or take a ring half a size bigger than your finger base measurement.
- Since the size of fingers changes during the day based on several factors, it is best to measure your finger at night when it is likely the largest.
