Как узнать размер кольца дома: 4 простых способа и таблица размеров

She once mentioned that she “has no idea” what her ring size is. You smiled, nodded and filed it away. Now the ring is chosen, and the only thing standing between you and the moment is one small number.

Quick answer: to measure your ring size at home, wrap a thin strip of paper or string around the base of your finger, mark where it overlaps, and measure that length in millimetres with a ruler. That is your finger circumference. Divide it by 3.14 to get the inside diameter, then find your size in the chart below. Already own a ring that fits? Measure its inside diameter edge to edge instead. That is the most accurate home method. When you know your number, every ring in our rings collection is made to that size.

Below you will find four ways to do it, a simple US, UK and EU size chart, and the small mistakes that make a ring too tight. All of it comes from the people who size and set rings by hand in Yerevan.

How do you measure your ring size at home?

There are four reliable ways, and you only need one of them. Pick the one that matches what you have on the table:

How to measure ring size with string or paper

This is the method most people use, and it works well if you are careful:

1. Cut a thin strip of paper about 1 cm wide. Paper is better than string, because string stretches.
2. Wrap it around the base of the finger the ring is for. Snug, but not squeezing.
3. Mark the spot where the paper overlaps with a pen.
4. Lay it flat on a ruler and read the length in millimetres. This is your circumference.
5. Now slide the loop over your knuckle. If it will not pass, add 1 mm.
6. Repeat it three times at different moments of the day and use the middle result.

How to find your ring size using a ring you already own

If a ring already fits the right finger, it holds the answer. Lay it on a ruler and measure the inside diameter, from inner edge to inner edge across the widest point, in millimetres. Do not include the metal.

That number is your size in our shop. A ring that measures 17 mm inside is a size 17. Easy.

How to use a printable ring sizer

A printable ring sizer is a page of circles or a paper strip that you print and wrap around your finger. Two rules make or break it:

• Print at 100% or “actual size”. “Fit to page” shrinks it and gives you the wrong size.
• Check the printout with a ruler first. If the test line says 5 cm, it must measure exactly 5 cm.

Place a ring you own on the circles and pick the one that matches the inside edge of the ring, not the outside.

How to measure ring size in mm (and what the number means)

Every ring size in the world is really just a measurement in millimetres with a different label on it. There are two numbers to know:

• Circumference: the distance around your finger. A 54 mm circumference is EU size 54.
• Inside diameter: the distance across the inside of the ring. Our sizes, from 16 to 20, are the inside diameter in mm.

To switch between them, use one simple sum: circumference ÷ 3.14 = diameter. So a 53.4 mm paper strip means a 17 mm ring.

Ring size chart: US, UK, EU and mm

Find your measurement in the first or second column, then read across. Our size is the inside diameter of the ring, the number you choose on our product pages. Finger is the distance around your finger. On a phone, swipe the table sideways to see every column.

Conversions are rounded to the nearest common size. If you fall between two sizes, choose the larger one.

How to measure ring size without them knowing

Planning a proposal is hard enough without asking “so, what’s your ring size?” at dinner. Four quiet ways to find out:

• Borrow a ring she wears on the same finger, measure the inside diameter, and put it back before she notices. A ring from her right hand is often a little bigger, so use it only as a backup.
• Press it into soap or clay to keep an outline, if you cannot take it out of the house.
• Trace the inside of the ring on paper with a sharp pencil, then measure the circle.
• Ask her best friend, mother or sister. Someone often knows, and most are happy to keep a secret.

Should a ring be tight or loose?

A ring that fits well slides over the knuckle with a little resistance and sits comfortably at the base. It should not spin around freely, and it should not leave a deep mark when you take it off.

Three things change the fit, and most sizing mistakes come from one of them:

• Temperature and time of day. Fingers swell in the heat and in the evening, and shrink in the cold. Measure at room temperature, later in the day.
• Band width. A wide band feels tighter than a slim one in the same size. For a band wider than about 4 mm, go up half a size.
• Knuckles. If your knuckle is much wider than the base of your finger, measure both and choose a size in between.

What is the average engagement ring size?

The most common women’s ring sizes are US 6 to 7, which is about 16.5 to 17.5 mm inside, or EU 52 to 55. Many jewellers treat US 6 as the “standard” size for an engagement ring.

But an average is only an average. A petite hand may wear a size 16, and a tall woman may wear a 19. If you have no way to measure, size 17 is a sensible middle, and it gives you room to adjust later on a plain band.

Engagement ring size guide: why getting it right first matters

A plain gold band can usually be resized. A ring with diamonds along the band is different. Pavé, half eternity and halo designs have stones set into the metal, and cutting and stretching that metal can loosen them. Some designs cannot be resized at all.

That is why we make every ring to your exact size instead of resizing a stock ring. If you are choosing a ring with a diamond band, such as our half eternity ring or the round solitaire with a pavé band, measure twice and order once.

Frequently asked questions

What is my ring size if I don’t have a ring sizer?
Wrap a thin strip of paper around the base of your finger, mark where it overlaps and measure the length in millimetres. Divide that number by 3.14 to get the inside diameter, which is your size in our shop. Do it three times for the most reliable result.

How do I know what my ring size is in US, UK or EU sizes?
Measure your finger in millimetres first, then use the chart above. EU sizes are the circumference in mm, US sizes are numbers like 6 or 7, and UK sizes are letters like L or N.

Is it better to size up or down?
If you fall between two sizes, size up. A slightly loose ring is more comfortable than a tight one, especially in warm weather or with a wide band.

Does ring size change over time?
Yes, a little. Fingers change with weight, pregnancy, age and even the seasons. Check your size again before you order a new ring rather than relying on a number from years ago.

Is the ring finger the same size on both hands?
Not always. Your dominant hand is often slightly bigger, so measure the exact finger on the exact hand where the ring will be worn.

Can you resize a ring with diamonds on the band?
Sometimes, but it is harder and riskier than resizing a plain band, because the stones are set into the metal. It is one reason we make every ring to the right size from the start.

Back to that one small number

It felt like the hardest part, and now it is a measurement on a strip of paper. Get it right, and the only surprise left is the one you planned: a ring that slides on the first time and stays.
