How to Get a Ring Size?
Ring Size Guide
Below is a comprehensive guide to help you accurately determine your ring size for everyday use. Follow these steps to ensure a comfortable, precise fit when purchasing a new ring.
1. Before You Measure
1.1 Choose the Right Time of Day
• Ideal Timing: Late afternoon (around 2–5 PM).
In the morning, fingers may be slightly smaller; in the evening, they may be a bit swollen. Measuring in mid‐afternoon usually yields the most average size.
• Avoid Extremes: Do not measure right after a heavy workout, after a long flight, or when your hands are very cold/hot. Exercise, dehydration, or temperature can temporarily alter finger size.
1.2 Environment & Tools
• Room Temperature (20–25 °C): A comfortable, moderate temperature ensures your fingers aren’t constricted or overly expanded.
• Recommended Tools (use one of these):
1. Ring Sizing Set (Metal or Plastic): A series of trial rings numbered in U.S. or metric sizes.
2. Printable Ring Sizer (Paper Loops): Print at 100% scale and cut out the paper rings.
3. String or Paper Strip + Ruler: For a makeshift measurement when no specialized tools are available.
2. Measurement Methods
2.1 Professional Ring Sizer
Accuracy: Highest
Where to use it: A jewelry store or if you already own a ring sizer set at home.
Steps:
1. Select a Trial Ring: Start with a ring larger than you think your size is.
2. Slide the Ring Over Your Knuckle: Gently push it down until it passes over your knuckle with slight resistance.
3. Find the Snug Fit Point: The ring should fit comfortably around the base of your finger—fitted but not pinching.
4. Read the Size: Note the number printed on that trial ring (e.g., U.S. size 6, U.K. size L, or a metric diameter/inner circumference).
Tip: Try on two or three adjacent sizes (for example, 6, 6.5, and 7) and choose the ring that slides on smoothly but requires a gentle twist to remove. That ensures a proper fit.
2.2 Printable Ring Sizer (Paper Loops)
Accuracy: High (if printed correctly)
Requirements:
• A high‐quality PDF or template from a trusted jeweler or jewelry retailer.
• A printer set to 100% scale (no “fit to page” or “shrink to fit”).
• A pair of scissors and a ruler (to verify print accuracy).
Steps:
1. Download & Print the Template: Make sure your printer settings are set to 100% original size.
2. Verify Scale: Use a ruler to confirm that a known measurement on the printout—such as a circle labeled “Diameter 16 mm”—actually measures 16.0 ± 0.1 mm on paper.
3. Cut or Create Paper Loops: Carefully cut out each paper ring loop.
4. Try the Loops On: Slide different loops onto your finger until you find the one that can pass over your knuckle with slight resistance and then fits snug around the base of the finger.
5. Note the Size: Record the size indicated on that paper loop (e.g., U.S. size 6, European 52, or diameter 16 mm).
Tip: If possible, ask a friend to help you hold the loop in place so you can gently pull or twist it to test the fit without cutting circulation.
2.3 String or Paper Strip + Ruler Method
Accuracy: Moderate (±0.5 mm potential variance)
When to use it: If you don’t have any specialized tools available.
Steps:
1. Cut a Narrow Strip: Use a piece of non‐stretch string, dental floss, or a 5 mm-wide paper strip.
2. Wrap Around Your Finger: Place it around the widest part of your finger (usually the center knuckle). Wrap it snugly—but not too tight—until it meets the starting point.
3. Mark the Overlap: Use a fine-tip pen to mark where the string or paper strip overlaps.
4. Measure the Length: Lay the marked string or paper flat and measure the length between the start and the marked point with a ruler (millimeters preferred). That length is your finger’s circumference.
5. Convert to Ring Size: Refer to a ring size conversion table (below) to find the corresponding size based on circumference.
3. Key Measurement Considerations
3.1 Measure Over the Knuckle
• A ring must be able to pass over your knuckle and still sit comfortably at the base of your finger. Always wrap your measuring tool around the widest part of the finger—usually the knuckle.
3.2 Temperature & Daily Fluctuations
• Very cold or very hot weather can shrink or expand your fingers slightly.
• Avoid measuring:
• Immediately after intense exercise
• After a long flight (circulation changes)
• First thing in the morning or late at night (fingers can be smaller or more swollen)
• Best practice: Measure at least twice on different days, then average the results if they differ by less than 1 mm.
3.3 Brand & Metal Variations
• Metal Type Affects Fit: Platinum, gold, and silver have different thickness and manufacturing tolerances. A U.S. size 7 in one brand may feel slightly tighter or looser in another.
• Ring Width Matters: Wider bands (≥ 6 mm) fit tighter than narrow bands (≤ 2 mm). If you plan to buy a wide band, you might need to go up by half a size (0.5 US size) compared to your normal measurement.
3.4 Seasonal & Lifestyle Factors
• Weight Fluctuations: If you’ve recently lost or gained 5 kg (11 lbs) or more, your finger size could change by 0.3–0.5 mm. In such cases, wait until your weight stabilizes.
• Pregnancy & Water Retention: Pregnancy can cause temporary hand swelling. Ideally, measure after any swelling subsides (often several weeks postpartum).
• Active Occupations: If your daily life involves heavy lifting, typing, or long periods of standing, your fingers may be slightly larger. In those cases, consider choosing a size 0.3–0.5 US sizes larger than your measured size for maximum comfort.
4. Purchasing & Trying On Rings
4.1 In-Store Try-On
• Most Reliable: If you have a local jeweler, visit them and try on a few rings in the same style and metal you plan to buy.
• Adjust on the Spot: Many jewelers offer one complimentary resizing (± 0.5 US size); ask about their policy before purchase.
4.2 Online Ordering
1. Check the Brand’s Specific Size Chart: Jewelers often publish their own ring‐sizing guides. Always follow those charts rather than a generic table.
2. Allow for Resizing: If you’re between sizes or unsure, it’s safer to order a slightly larger ring and have it resized later.
3. Return/Exchange Policy: Confirm that the store allows free or low-cost exchanges/resizing if the ring doesn’t fit.
4.3 Custom Designs & Allowances
• Custom-Made Rings: Ask the jeweler to leave a 1 mm (± 0.5 US size) margin in the band’s inner circumference. This ensures the ring can be resized if your finger size changes.
• Wide Bands or Comfort Fit: Always try on comfort-fit and wide bands in person or request a paper-loop test of that specific style, because fit can feel different than a standard narrow band.
5. Frequently Asked Questions
Q1: Where on my finger should I measure?
• A: Wrap the measuring tool around the widest part of your finger (the knuckle), then let it rest at the base. Only then will the resulting size guarantee the ring can slip over the knuckle easily.
Q2: My left ring finger is a size 6—does that mean my right ring finger is also 6?
• A: Not necessarily. Most people have slight differences between fingers and between hands. Always measure each finger separately. It’s common for the right ring finger to be 0.5–1 US size different from the left.
Q3: Will my ring size change if I lose or gain weight?
• A: Yes. A 5 kg (11 lb) weight change can alter finger circumference by about 0.3–0.5 mm (roughly 0.5 US size). If you anticipate further weight changes, measure when your weight is stable.
Q4: What about measuring during pregnancy?
• A: Pregnancy often causes temporary swelling. It’s best to wait until after childbirth or allow several months for your body to return to its pre-pregnancy state before measuring.
Q5: My knuckle is larger than the base of my finger—what should I do?
• A: Wrap the sizer so that it can pass comfortably over your knuckle. Once it’s past the knuckle, it should fit snugly at the base of your finger. That ensures you can slide the ring on and off without pinching.
Q6: Are chart measurements the same across all jewelers?
• A: No. Slight variations (± 0.2–0.5 mm) can occur depending on manufacturing tolerances, the metal used, and brand standards. Always refer to the specific jeweler’s size chart or request an in-person fitting whenever possible.
