How to Measure Your Ring Size

Choosing a ring, whether an everyday band, a wedding band or an engagement ring, always starts with one essential step: knowing your ring size. A perfectly fitted size ensures not only comfort but also the longevity of the piece, especially for a creation made in 18k gold or platinum, like those offered by Laveran Paris, an ethical fine jewelry house specializing in lab-grown diamonds.

Many people wonder "how do I find my ring size?", "how do I measure a ring size?" or "what is the right ring size for a woman?" In this complete guide, we help you easily determine your ring size, whether you are at home without any special tools or already own a ring that fits you perfectly.

How to find your ring size: the different methods

To measure your ring size accurately, there are several simple methods you can use at home. Each one can help you find out your ring size, whether or not you already have a reference ring. Here are the most reliable techniques for determining ring sizes.

Method 1: Measure your ring size with a ring you own

If you already have a ring that fits you perfectly, this is the most accurate method.

1. Choose a comfortable ring, worn on the same finger as your future piece.
2. Measure the inside diameter to the nearest millimeter (with an accurate ruler).
3. Look up the measurement in a ring size guide to find the corresponding French size.

It is one of the most reliable ways to know your ring size without error.

Method 2: Measure your ring size with a tape measure

If you don’t have a ring, don’t worry.

1. Wrap a flexible tape measure around your finger.
2. Note the circumference in millimeters.
3. Compare it with a ring size guide to find the corresponding size.

This method makes it very easy to measure a ring size based on the actual circumference of your finger.

Method 3: Measure your ring size with string or thread

A simple solution, though slightly less precise:

1. Wrap a piece of thread around your finger.
2. Mark the point where it meets.
3. Measure the length with a ruler.

This gives a fairly reliable estimate of which ring size to choose.

How to determine the size of an engagement ring

Choosing the size of an engagement ring calls for even more precision, since this precious piece is meant to be worn for a lifetime. Here are the recommendations of our Laveran Paris experts.

1. Take the width of the band into account

A slim ring (a classic solitaire) is worn in your exact size.
A wider band may require going up half a size for optimal comfort.

2. Consider the metal: 18k gold vs. platinum

• 18k rose, yellow or white gold: slightly more malleable, perfect for a precise fit.
• Platinum: denser, it can feel slightly tighter.

This affects how the size feels.

3. Discreetly find out your partner’s ring size

If the ring is meant to be a surprise:

• borrow a ring she wears on the same finger;
• ask a friend or family member;
• discreetly observe the size of the rings she already wears.

4. Check the measurement several times

For a solitaire or halo set with a lab-grown diamond, a sizing error can be more complicated to correct, depending on the setting.
That is why an accurate measurement matters.

How to measure your ring size at home

It is entirely possible to measure your ring size at home, whether or not you have a reference ring. Here are the three simplest, most reliable methods for finding your ring size without going anywhere.

1. With a ring you own

• Measure the inside diameter with an accurate ruler.
• Compare the measurement with a ring size guide.
  It is the quickest way to find out your ring size if you already have a piece that fits perfectly.

2. With a tape measure

• Wrap the tape around the finger in question.
• Note the exact circumference in millimeters.
• Find the corresponding size in a ring size guide.
  This method is ideal for measuring your ring size at home if you don’t own a ring yet.

3. With string or a strip of paper

• Wrap a piece of string around your finger.
• Mark the point where it meets.
• Measure the length.
  This simple technique lets you find your ring size without any special accessories.

Laveran Paris tip: take several measurements at different times of day. Fingers can vary slightly with heat, cold or hydration.

How to measure the right ring size for a woman or a man

The right ring size can vary depending on the finger, your build, the width of the band and the type of ring. Here are a few useful benchmarks for choosing a women’s ring size or men’s ring size with confidence.

1. The most common ring sizes for women

For women, the most common sizes (French sizing) fall between:

• 50 and 54 for most fingers
• 48 and 50 for slender fingers
• 55 and 57 for slightly larger fingers

These figures are based on the best-selling women’s ring sizes.

2. The most common ring sizes for men

For men, we generally see:

• 58 to 62 as the most frequent range
• 63 to 66 for larger hands

Men with a sturdier build will naturally wear larger ring sizes.

3. Take the width of the band into account

• A slim ring (1.2 to 2 mm) is worn in your exact size.
• A wide ring (4 to 8 mm) may require going up half a size or a full size for optimal comfort.

4. The influence of the metal: 18k gold or platinum

• 18k gold (rose, yellow or white), the precious metal used at Laveran Paris, offers a precise, comfortable fit.
• Platinum, which is denser, may feel slightly tighter.

These factors are essential when choosing the right ring size, especially for a piece meant to be worn every day.

How to find out her ring size without her knowing

If you want to give a ring as a surprise — especially an engagement ring — there are several discreet ways to find out her ring size without her knowing.

1. Borrow one of her rings

This is the simplest method:

• Take a ring she wears on the same finger you have in mind.
• Measure the inside diameter or take it to a jeweler.
• Remember to put the ring back exactly where you found it so as not to raise suspicion.

2. Use a ring as a template… without taking it

If you can’t take it with you:

• Discreetly press the ring into a bar of soap, modeling clay or a sheet of paper.
• This gives you an imprint of the diameter.
  An undetectable trick for finding a woman’s ring size.

3. Ask a friend or family member for help

People close to her can help you get her ring size without drawing attention:

• a sister,
• a best friend,
• a family member.

They can also encourage her to try on rings "just for fun" and pass the information on to you.

4. Observe her jewelry habits

If she often wears rings:

• Notice which finger she wears them on
• Note the style and approximate size
  This can give you a useful estimate.

5. Choose a standard size if all else fails

If you are completely unsure:

• for a woman, French size 52 is the most common;
• for a man, French size 60 is the most common.

And of course, at Laveran Paris, creations in 18k gold or platinum can be resized depending on the setting.

What to do if you don’t have a ring

Even without a reference ring, it is entirely possible to find your ring size accurately. Here are the most reliable ways to measure your finger at home.

1. Use a flexible tape measure

This is the best alternative:

• Wrap the tape around the finger you want to measure.
• Note the circumference in millimeters.
• Refer to a ring size guide.

This method offers excellent precision for determining your ring size.

2. Use string, thread or a strip of paper

• Wrap your chosen material around your finger.
• Mark the point where it meets.
• Measure the length with a ruler.

It is a quick, simple solution when you don’t have any specific tools.

3. Ask someone close to you who owns a ring sizer

Some jewelry lovers and seamstresses already have one: a discreet and effective solution.

Laveran Paris advice: measure your finger at several times of day to get a reliable average.

What to do if the ring size isn’t right

Even if you take every precaution, the ring size may not be perfect on the first try. Here is what you can do, depending on the type of ring and the metal.

1. Have it resized by a professional

Most 18k gold and platinum rings can be resized:

• sized down if the ring is too big,
• sized up if it is slightly too small.

Plain bands and classic solitaires are generally the easiest to resize.

2. Understand the limits of each setting

Some rings are more delicate:

• Rings set with stones all the way around
• Multiple ornaments
• Very wide wedding bands

In these cases, the jeweler may suggest a special adjustment or a partial remake.

3. Don’t force a ring that is too tight

A ring that is too tight can become uncomfortable, or even difficult to remove.
It is better to have it resized than to force it.

4. Anticipate natural changes in your finger

Fingers change slightly depending on:

• heat,
• cold,
• water retention,
• the time of day.

If your ring is comfortable in most situations, the size is probably right.

At Laveran Paris, our 18k gold and platinum rings are designed to offer an ideal, lasting fit. Resizing can be considered depending on the model and the structure of the setting.
