How to Find Your Ring Size

Ring Size Made Simple. Find the Fit That Feels Like You

Your jewelry should fit like it was made just for you, because it is.

Finding your ring size goes beyond numbers; it’s about feeling connected to a piece that moves with you through every moment. Whether you’re marking a milestone, gifting a loved one, or celebrating yourself, the perfect ring brings comfort, confidence, and joy. This guide helps you learn how to find your ring size accurately at home so every piece from Made by Mary feels effortlessly personal.

Your finger size reflects the balance between comfort and precision. It’s measured by two key details: circumference, or the distance around your finger, and diameter measurement, or the width across the inside of the ring. Together, they determine how securely and comfortably your ring sits. Even a small change, like a quarter-size or half-size, can affect how a ring feels. A tighter fit may restrict movement, while a looser fit might twist or slip. The goal is a proper ring size that rests gently at the base of your finger and glides over your knuckle size with ease.

You don’t need a jeweler to measure your ring size accurately. 

Finding your size at home is simple with a few everyday items, or with our Made by Mary Ring Sizer. Whether you use a measuring tape, tape measure, or string flat, you can get accurate results with these simple ring sizing tips.

Method 1 – Use a Flexible Measuring Tape

Use a soft, flexible measuring tape and wrap it directly around the base of your finger where the ring will sit. Make sure the tape is snug but not tight. Note the measurement in millimeters, then compare it to our millimeter-to-size chart on the Made by Mary Jewelry Sizing Chart page.

Pro Tip: Measure at different times of day, ideally later, when your fingers are naturally warm. Finger size fluctuates throughout the day, so taking a few measurements will give you the most accurate result.

Method 2 – Use an Existing Ring

If you already have a ring that fits perfectly on the same finger, use it for reference. Measure the inside diameter of the existing ring in millimeters, then check a printable ring size chart or printable ring sizer for your match. This quick method ensures your new ring will be the correct size before ordering.

Method 3 – Try the Made by Mary Ring Sizer

For the most accurate measurement, use theMade by Mary Ring Sizer, a small, adjustable tool designed to take the guesswork out of accurate ring sizing. Simply print or request one of our free ring sizers from our website. The printable ring option is perfect if you prefer similar tools, you can use straight from your jewelry box.

Your ring size can shift based on your body and environment. 

Warm weather, hydration, and physical activity can make your fingers expand slightly, while cooler temperatures may shrink them. Even your dominant hand can have a different finger size. These natural changes can alter your measurement falls by a quarter size or more.

To get the most accurate measurement, we recommend measuring your finger a few times throughout the day and averaging the results. You’ll end up with an ideal ring size that feels comfortable year-round.

Life stages like pregnancy or hormonal shifts can also affect finger size. Knowing these factors helps you choose a correct ring size that adapts over time.

Your ring should move easily, reflect your personal preferences, and feel like it belongs to you. Whether you love slim stacking bands or wedding bands, the right ring size ensures your jewelry stays secure and elegant.

Slim Bands vs. Wide Bands

Wider bands sit closer to the finger, so consider sizing up slightly to maintain comfort. Slim, delicate bands like Made by Mary’s stacking rings fit true to size and move naturally. The thinner the band, the lighter and more flexible it feels.

Stacking Rings

When building a stack, leave a bit of space for movement. Slight separation between rings keeps the stack comfortable and stylish. Mix sterling silver, gold-filled, and rose gold-filled pieces to tell your story layer by layer.

Seasonal and Everyday Fit

The ideal ring should slide over your knuckle with a little resistance, resting securely without feeling tight. If you’re active or live in a warm climate, choose a slightly larger size that stays comfortable even with swelling. A ring that fits well moves with you: your perfect fit that complements your rhythm and your story.

Q: What if I’m between ring sizes?
Choose the slightly larger size. Fingers naturally swell throughout the day, and a bit of extra space ensures your ring remains comfortable.

Q: Can I resize Made by Mary rings later?
Some rings can undergo a ring resizing process by a professional jeweler, but it depends on the metal and structural integrity of the piece. Gold-filled bands, for instance, may have limitations. When in doubt, measure first for the most accurate sizing and check each product page before purchase.

Q: How can I secretly find someone else’s ring size?
Borrow a ring they wear on the same finger and measure its inner circumference or inside diameter. If that’s not possible, trace it carefully or compare it with standard ring sizes using a printable ring sizer. Remember, your partner's ring size can vary slightly from your own due to dominant hand or lifestyle.

Q: What’s the average ring size for women?
In the U.S., the average ring size for women is around a size 6, though many fall within the 5–7 range. But every hand is unique. Always measure for your exact size rather than relying on averages.

Q: What if I’m shopping for an engagement ring or wedding band?
When choosing an engagement ring or wedding bands, it’s essential to find your accurate ring size first. These rings are worn daily, so comfort and security matter. Use our ring sizer or printable ring size chart to find ring size that ensures your ring fits beautifully for every moment.

A perfect ring doesn’t just fit your finger, it fits your life. When your ring feels right, it becomes part of your rhythm. It moves with you, celebrates with you, and becomes a quiet witness to every moment that matters. Whether you’re embracing change, honoring connection, or celebrating yourself, your ideal ring size awaits: crafted with care and intention by Made by Mary.
