How To Measure Your Ring Size At Home: 3 Easy Methods
If you're wondering how to check your ring size at home, these are the easiest and most reliable methods.
1. Use Our Printable Ring Sizer (Most Accurate)
The easiest way to measure your ring size at home is by using our printable ring sizer. Because it uses an existing ring for comparison, it's often the most accurate way to measure your ring size at home without visiting a jeweller.
Our Head of Product Design, Anna Tipton, recommends this method:
"The best way to check your ring size at home is to print the guide and make sure it's printed to scale. Take a ring that already fits the finger perfectly and place it over the circles until you find the best match. Alternatively, carefully cut out the circle and slide it over your finger to check the fit."
You can download our printable guide and follow the simple instructions on our Find Your Perfect Fit page.
2. Measure Your Finger With Paper or String
If you don't have a printer, here is an alternative for how to measure ring size at home.
Simply:
-
Wrap a piece of string or a thin strip of paper around the base of your finger.
-
Make sure it feels snug but comfortable.
-
Mark where the ends meet.
-
Measure the length in millimetres using a ruler.
-
Compare your measurement with our chart to find your size.
This is one of the most popular ways how to find out your ring size at home, especially if you're ordering a ring online.
3. Measure a Ring You Already Own
If you already have a ring that fits comfortably on the finger or you're looking to surprise someone special, you can use it to determine your size.
Place the ring over a ruler and measure the inside diameter in millimetres, or compare it directly against our printable ring guide. You can then match the measurement using our Ring Size Chart.
This method works particularly well if you're buying a gift and want to discreetly check your ring size at home without measuring your finger.
Our Top Tips On How To Measure Ring Size At Home
Whichever method you choose, these simple tips will help you get the most accurate measurement.
-
Measure your finger more than once throughout the day, as finger size naturally changes with temperature.
-
Avoid measuring when your hands are very cold, as your fingers may be slightly smaller than usual.
-
Make sure your measuring tool feels snug but isn't tight.
-
Remember that wider ring bands often feel tighter, so you may prefer to size up slightly.
What If You're Between Ring Sizes?
If your measurement falls between two sizes, we generally recommend choosing the larger size. This helps ensure your ring slides comfortably over your knuckle while still feeling secure once it's on.

Frequently asked questions
How do I know if I've measured my ring size correctly?
Your ring should slide comfortably over your knuckle and feel secure once it's on. If you're unsure, measure twice and compare your results using our printable ring sizer.
Can I measure my ring size with a ruler?
Yes. You can use a ruler to measure the length of a piece of string or paper wrapped around your finger, or measure the inside diameter of a ring you already own.
Is it better to measure your finger or a ring?
If you have a ring that already fits perfectly, measuring that is often the most accurate option. Otherwise, measuring your finger with string, paper or a printable ring sizer works well.
Does finger size change with the weather?
Yes. Fingers can swell in warm weather and shrink slightly when it's cold. For the most accurate result, measure your finger at room temperature.
Can I measure my ring size for a surprise gift?
Yes. If possible, borrow a ring they already wear on the correct finger and compare it with our printable ring sizer.
Are ring sizes the same for every finger?
No. Each finger can be a different size, and your dominant hand is often slightly larger. Always measure the finger you'll be wearing the ring on.
Do engagement rings and fashion rings use the same sizing?
Yes. Ring sizing is the same regardless of the style, whether you're shopping for an engagement ring, a personalised ring or an everyday piece.
Can I measure my ring size on my phone?
While some apps can help estimate your size, a printable ring sizer or measuring an existing ring is generally more accurate.
What if my measurement falls between two sizes?
If you're between sizes, it's usually best to choose the larger size for a more comfortable fit, particularly for wider bands.
How many times should I measure my ring size?
For the best accuracy, measure your finger two or three times at different points during the day and compare the results.
