Why a ‘Close Enough’ Size Isn’t Enough

Sarah thought she nailed her husband’s ring size—until he nearly lost it surfing in Malibu.
Resizing costs 50−150 in the USA. Save time and money!

A ring that’s too tight can leave indentations (ouch!), while a loose one risks slipping off forever. Here’s what most people don’t consider:

• Resizing Costs: Most USA jewelers charge 50–50–150 per resize, and some designs (like eternity bands) can’t be adjusted.
• Time Crunch: If you’re planning a surprise proposal, you won’t have time for last-minute fixes.
• Comfort Matters: 82% of wearers in a 2023 Brides survey said they’d rather skip a day wearing their ring than deal with a bad fit.

“💡 Teddy Jewellers Hack: If you’re buying a gift, opt for a sizing-neutral design (e.g., adjustable bands or open cuffs) to avoid guesswork.”

Comfort and Fit

A ring that’s too tight can cause discomfort and swelling, while a ring that’s too loose may slip off and get lost. Ensuring the right fit is crucial for both comfort and security.

Aesthetics

A well-fitted ring sits perfectly on your finger, enhancing its beauty and showcasing the design. A poorly fitted ring, on the other hand, can look awkward and detract from its appearance.

5 Foolproof Methods to Measure Ring Size at Home

No Tools? No Problem! 5 DIY Methods (Tested by Jewelers)

Method 1: The Paper Strip Trick (Free & Easy)

Perfect for: Secret proposers or late-night shopping.

Steps:

1. Cut a 4-inch strip of paper (width: 0.5 inches).
2. Wrap it snugly around the base of the finger.
3. Mark where the paper overlaps.
4. Measure the length in millimeters.
5. Use our FREE Ring Size Chart (below) to convert to USA sizes.

⚠️ Avoid This Mistake: Don’t measure cold fingers! Body temperature drops overnight, shrinking fingers by up to half a size. Measure at 8 PM for the most accurate reading.

Use an Existing Ring

Ideal if: You’re replacing a ring they already wear daily.

1. Place the ring on top of our printable ring size chart (download here).
2. Match the inner diameter to the chart.

Teddy Jewellers Tip: If the ring fits their middle finger, subtract 0.5 sizes for the ring finger.

Method 3: Order a Free Ring Sizer Kit (USA Brands)

Best for: Perfectionists who want pro tools.
Many USA jewelers offer free ring sizers, including:

• James Allen: Free plastic sizer (takes 3–5 days to ship).
• Blue Nile: Printable chart + virtual sizer.
• Kay Jewelers: In-store sizing (ask for a “loaner kit”).

👉 Pro Hack: If you’re sizing a surprise engagement ring, borrow a ring from their jewelry box and press it into a bar of soap to create a mold. Take it to any jeweler for measurement!

Top 3 Mistakes to Avoid (With Visuals)

Don’t Let These Blunders Ruin Your Ring

Mistake 1: Ignoring Knuckle Size

If your partner has large knuckles, measure the base AND knuckle, then average the two. For example:

• Base: Size 7
• Knuckle: Size 7.5
  Ideal Size: 7.25 (round up to 7.5 for comfort).

Mistake 2: Measuring at the Wrong Time

Fingers shrink in cold weather and swell in heat. The best time to measure:

• After a warm shower.
• At night (8–10 PM).
• Avoid mornings (fingers are smallest after sleep).

Tips for Accurate Measurement

1. Measure at the End of the Day: Fingers tend to swell throughout the day, so measuring later ensures a more accurate fit.
2. Consider the Knuckle: If your knuckle is larger than the base of your finger, measure both and choose a size in between.
3. Temperature Matters: Cold weather can shrink your fingers, while heat can make them swell. Measure when your hands are at a normal temperature.

Understanding Ring Size Variations

International Ring Sizes

Ring sizes can vary internationally. It’s important to know the conversion if you’re purchasing from a different country. Here’s a quick reference:

• US and Canada: Sizes are typically measured in numbers (e.g., 6, 7, 8).
• UK and Australia: Sizes are given in letters (e.g., L, M, N).
• Europe: Sizes are based on circumference in millimeters (e.g., 52, 54, 56).

Width of the Ring

The width of the ring band can affect the fit. Wider bands tend to fit more snugly, so you might need to go up half a size for wider rings.

Ring Styles

Different ring styles can also impact sizing. For example:

• Comfort Fit Rings: These have a rounded interior and may fit differently than standard rings.
• Eternity Bands: Due to the continuous line of stones, these rings may feel tighter.
