Why Ring Size Matters

Before we get into all of the details of taking your measurements, we want to address why fit matters in measuring your ring. Fit is so much more than just a number; it is about fitting the ring into your life in an easy, comfortable, everyday way.

Comfort and Daily Wear Considerations:  

Think about it, you have this beautiful ring, and it either digs into your finger or, worse, it spins around. To be honest, a ring that is the correct size feels almost like a second skin. You forget it is there, and you carry on with your day. When it comes to your lab diamond ring, you want to be thinking about the diamond, not discomfort.

Cost Implications of Resizing:  

Most rings can be resized; however, it will generally come at some cost and may alter the integrity of the design depending on the degree of adjustments, notably lab diamond rings having a finer band. Knowing how to size a ring properly in advance would save all involved a headache in the form of time, money, and an almost certain heartbreak.

Professional Appearance and Confidence:  

To be blunt, a well-fitted ring looks better. It sits properly, seems comfortable, while putting your hand and the incredible brightness of the lab diamond front and center. Without that subtle detail, you're giving up a little confidence, and overall, just look less polished.

Safety Concerns:  

A loose ring has way more potential to fall off in everyday situations, increasing the risk of losing it. Too small is uncomfortable and may limit blood circulation or may even require a professional to cut it off in rare instances. For something as sentimental as a lab diamond engagement ring, you'll ideally want to make sure the ring can stay on your finger!

DIY Methods: Measuring Your Own Ring Size at Home

Ready to get started? Below are a few different, simple, and proven ways to determine how to measure your ring size right from your own home.

The String/Paper Strip Method

This method is a popular one for a reason: It's easy, items you need are usually readily found in your home, and to your surprise, it often can produce accurate results!

Step-by-step instructions with measurements:

1. You will need a piece of non-stretchy string, a strip of paper about ¼" wide, or even dental floss. 

2. You will want to wrap the string/paper snugly around the base of the finger that you plan to wear the ring on. Just make sure it is snug but not too tight to pinch any skin.  

3. Make a mark where the string or paper has overlapped with a pen. 

4. Remove the paper or plastic string and carefully lay it flat. 

5. Use a ruler to measure in millimeters (mm) the actual length from the start to the mark you made.

Pro Tip: Measure your finger at the end of the day; this will give you the most accurate size.

To convert to US ring sizes, it’s simply a case of using this handy guide: a 14.1mm circumference equals a size 3. Every size above that will be about an additional 2.6mm added to the circumference. So if you measured 57mm, you would divide it by 3.14 to get about 18.1mm in diameter. So approximately a size 8.

Using a Ring You Already Own

Have a ring that fits your ring finger exactly and perfectly? You're halfway there! This is a good method to use when you're deliberating how to tell your ring size without any measuring tools.

Simply grab a ruler and measure the inside diameter of a ring that fits comfortably. Place the ruler across the center of the ring's opening and note the number of millimeters from inside edge to inside edge. Take that diameter and plug it into a ring size chart: If the number is around 17.3mm, most size 7 rings in the US should fit best.

The rub here is ensuring you’re measuring a ring that fits the correct finger! Your ring finger (fourth finger) will usually be a different size from your other fingers, perhaps by as much as a half size or more.

Printable Ring Sizers

Printable ring sizers incorporate high-tech into low-tech measuring, and they are surprisingly accurate if you take the time to use them properly.

Search for 'printable ring sizer' and find a reputable jewelry site to download one from. The first step is to check that your printer is calibrated. If you can, make sure your printer is set at 100% scale (don't reduce or enlarge size when printing).

Most printable ring sizers provide a test ruler to ensure that the sizing is proper. 

Once downloaded and printed, cut out the sizer portion and follow the directions provided. The ring sizers will ask you to slide your finger through holes of different sizes until you find the right fit. Think of it as a mini Goldilocks experience, only for rings!

Professional Ring Sizing Tools

While these DIY hacks have already proven to determine your ring size, we still understand if someone wants to deal with professional tools to find the exact size. If you’re one of them, you can either buy a ring sizer or a ring gauge from your favorite e-commerce store, or you can simply visit your nearest jewelry store, where you can get your finger measured for free!

The Subtle Art of Sizing a Ring in Secret

Planning a surprise proposal with a beautiful lab diamond engagement ring? Good for you! It’s super romantic, but you also need to contend with another wrinkle in the ‘how do you tell your ring size’ conundrum. Fear not, secret agents of love, we’ve got some stealthy tricks for you!

Stealth Techniques

Borrow a ring: Sneakily get a ring they already wear on their ring finger and use one of the above methods to measure it.

Phone a friend: Their sibling, best friend, or roommate might already know or be able to subtly find out.

Initiate light-hearted conversation: “Do you think my fingers are bigger than yours?” Some flirtation might give you the answer.

Creative Approaches

"Let's just try different rings for fun" game: Go with them to window-shop for fun and agree to ‘just look,’ then make notes!

Use their jewelry box: See what size they wear regularly, especially on the ring finger.

Pretend you’re ring shopping for somebody else: Ask them for their ring size opinion and borrow their finger for measurements.

Technology Solutions

Yeah, there's an app for that.

Ring sizing apps let you put a ring on your phone screen and measure it.

Photo comparison tools allow you to snap a picture of the ring resting against a commonly sized item, such as a coin, to provide some scale

If you’re still not sure, a Friendly Diamonds expert will be able to guide you through all of this with absolute discretion!

Professional Ring Sizing: When to Visit a Jeweler

Sometimes, there's just nothing you can do yourself to salvage the situation, especially when you don't have the space to DIY the return, exchange, or resizing process. That's when you need to call in the professionals and visit a jeweler.

When you go for a professional fitting, a jeweler will measure your finger with calibrated ring sizers, usually a few times to correct for your knuckle size, seasonal factors, and the particular width of the setting you’ve picked. And they’ll have insight on fit, if you’re considering a lab diamond ring setting that affects the fit and comfort in exemplary or challenging ways.

Timing matters for professional sizing, too. Your digits tend to be their absolute most accurate size when your fingers are at normal temperature: in the afternoon, when they're not swollen after sleeping or exercising. It might not be the best idea to book an appointment right after a workout, during an especially hot or cold day, or when you're under the weather.

Common Ring Sizing Mistakes to Avoid

If you are inquiring as to how to determine your ring size and want to avoid making mistakes, here are a few things to consider:

Do not measure cold fingers; they shrink!

Do not assume all fingers are the same. They are not! Most importantly, your left ring finger can be different in size from your right.

Consider the width of the band; wider bands tend to feel tighter, so you can usually take a half size larger.

Of course, knuckles also need to be thought of; if your knuckle is larger than the base of your finger, then you should look for a size that will easily glide over the knuckle and not spin around after it has been worn.

Ring Sizing for Different Ring Styles

Fit is certainly not created equal for rings.

Wide Bands: You may want to consider one-half size larger than usual for comfort.

Thin Bands: These offer room but may feel loose.

Stackable Rings: Leave room for multiple rings or size according to how you plan to stack them.

Complex lab diamond settings may restrict comfort, which will make sizing critical.

Frequently Asked Questions

How do you tell your ring size accurately at home?

There are three key ways to find your ring size at home and for free. You can measure your ring size using a string or strip of paper, use a ring you currently own and find comfortable, or purchase a downloadable ring sizer for the most accurate measurements. If you're using string or paper, measure your finger at the end of the day, when it is most likely at its largest. You should also avoid taking measurements while your hands are cold, as this will make your ring size falsely smaller. If you are still unsure about your ring-size measurement, try your hand at multiple measurements to get the most accurate size.

Can I secretly determine someone’s ring size?

Yes, and it is sneakier (and sweeter) than you might think! You can borrow a ring they wear on their ring finger, enlist help from a close friend, or start a casual conversation about jewelry. Technology like ring sizing apps or photo comparison tools can also help. It all comes down to knowing how do you tell your ring size creatively!

What ring size is most common for a woman in the US?

The most common ring size for women in the US is 6! But everyone’s fingers are different, so don’t make assumptions! Read more to learn how you can determine your ring size using at-home methods or by seeking help from a jeweler.

Can a lab diamond ring be resized after the time of purchase?

Yes, most lab diamond rings are resizable, although it may get a tad tricky with some ring styles or settings. Eternity bands or tension-set rings, for example, may present more of a challenge in resizing. Knowing how do you tell your ring size when ordering a ring could save time and money in resize costs.

What's the best time of day to determine your ring size?

The best time to measure your ring size is in the evening when your fingers are slightly swollen from the day’s activity. Avoid early morning or cold conditions, as they can give you a smaller-than-actual size. Knowing how do you tell your ring size is also about choosing the right time!

Can finger size fluctuate?

Yes. Your fingers can change size due to factors like weight fluctuation, temperature shifts, pregnancy, or even traveling. If you haven’t worn rings for a while, it’s worth re-identifying your size. Trust us, learning how do you tell your ring size isn’t a one-and-done job.

Do wide bands and thin bands affect sizing?

Yes! Wider bands are more snug on the finger, and you'll likely want to go up a half size or more. Thinner bands will feel looser and may be better suited for stacking. Keep ring band style in mind when determining how do you tell your ring size with a particular design.
