Ring Sizing Guide

RING SIZE GUIDE

Find Your Perfect Fit


WHY PROPER SIZING MATTERS

A properly fitted ring should: ✓ Slide on with slight resistance
✓ Fit snugly over your knuckle
✓ Not spin excessively on your finger
✓ Come off with gentle effort (not easily, not impossibly)

Too loose: Risk of loss, ring spinning, discomfort
Too tight: Difficult to remove, restricted circulation, discomfort


METHOD 1: MEASURE AT HOME (STRING METHOD)

What You'll Need:

  • String, dental floss, or thin strip of paper
  • Ruler or tape measure
  • Pen or marker

Instructions:

Step 1: Cut a piece of string about 6 inches long

Step 2: Wrap the string around the base of your finger (where you'll wear the ring)

  • Wrap snugly but not too tight
  • The string should slide over your knuckle comfortably

Step 3: Mark where the string overlaps with a pen

Step 4: Measure the string length from the end to your mark in millimeters

Step 5: Use the chart below to find your size

Conversion Chart:

Inside Circumference (mm) US Size UK Size

59.5mm 9
62.1mm 10
64.6mm 11
67.2mm 12 Y
69.7mm 13 Z+1

Can't find your exact measurement? Round UP to the nearest size. It's easier to size down than up.


METHOD 2: USE AN EXISTING RING

What You'll Need:

  • A ring that fits the same finger
  • Ruler with millimeter markings

Instructions:

Step 1: Find a ring you already own that fits the finger you want to wear your new ring on

Step 2: Measure the inside diameter of the ring in millimeters

  • Place the ring on a flat surface
  • Measure straight across the inside from edge to edge
  • Measure in millimeters for accuracy

Step 3: Use this chart to find your size:

Inside Diameter (mm) US Size
14.1mm 3
14.9mm 4
15.7mm 5

METHOD 3: VISIT A JEWELER (MOST ACCURATE)

Your local jewelry store can measure your finger with a professional ring sizer. This is the most accurate method and takes just a few minutes.

Bring this information when you visit:

  • Which finger you'll wear the ring on (they may be different sizes!)
  • Whether the ring will be a wide band (6mm+) or thin band (2-3mm)

Pro tip: Many jewelers offer this service for free, even if you're not purchasing from them.


IMPORTANT SIZING CONSIDERATIONS

1. Knuckle Size

If your knuckle is significantly larger than the base of your finger:

  • The ring must fit over your knuckle to get on
  • But it should fit snugly at the base to prevent spinning
  • Consider sizing up and using sizing beads (we can add these during resizing)

Test: If you measure 6.5 at the base but 7.5 at the knuckle, order size 7 or 7.5.


2. Wide Bands Need Larger Sizes

Rings wider than 6mm fit more snugly than thin bands.

General Rule:

  • Thin bands (2-3mm): Order your true size
  • Medium bands (4-5mm): Consider sizing up ½ size
  • Wide bands (6mm+): Size up ½ to 1 full size

Bravais Bombe Rings: Our signature bombe rings are typically 5-8mm wide. We recommend sizing up ½ size for comfort.


3. Temperature & Time of Day

Your fingers swell and shrink throughout the day due to:

  • Temperature (fingers swell in heat, shrink in cold)
  • Time of day (often larger in the evening)
  • Hydration levels
  • Physical activity
  • Sodium intake

Best time to measure: Late afternoon/early evening in moderate temperature when you're well-hydrated.

Avoid measuring:

  • First thing in the morning (fingers are smaller)
  • During extreme heat or cold
  • After intense exercise
  • When very dehydrated

4. Dominant Hand Considerations

Your dominant hand fingers are often slightly larger due to increased use.

If you're right-handed:

  • Right hand fingers may be ½ size larger than left hand

For engagement/wedding rings:

  • Most people wear on left ring finger (regardless of dominance)
  • Make sure to measure the SPECIFIC finger you'll wear it on

5. Finger-Specific Sizing

Each finger may be a different size! Common patterns:

  • Index finger: Often ½-1 size larger
  • Middle finger: Typically largest
  • Ring finger: Standard reference
  • Pinky finger: Often 2-3 sizes smaller

Always measure the specific finger where you'll wear the ring.


RING SIZING AT BRAVAIS

Initial Sizing:

All Bravais rings are listed with their current size. We offer complimentary resizing before shipping for most designs.

When ordering:

  1. Add item to cart
  2. In "Order Notes" at checkout, specify: "Please resize to [size]"
  3. We'll resize before shipping (may add 3-5 business days to production)

Designs that cannot be resized:

  • Eternity bands (stones all the way around)
  • Full pavé bands
  • Certain carved patterns
  • We'll note on the product page if resizing is not available

Ring Sizing Insurance:

Recommended! Purchase one-time ring sizing insurance at checkout.

What it includes: ✓ One complimentary resize anytime during the life of the ring
✓ Cleaning and inspection included with resize
✓ You only pay return shipping to us

Cost: $25-50 (depending on ring complexity)

Why we recommend it:

  • Fingers change size over time (weight changes, pregnancy, aging)
  • You might prefer a different fit after wearing it
  • Temperature variations affect fit
  • Peace of mind for a one-time fee

Resizing After Purchase (Without Insurance):

Cost: $75-150 depending on design complexity

Limitations:

  • Rings can typically be sized +/- 2 sizes maximum
  • Beyond 2 sizes may compromise the design
  • You pay return shipping both ways
  • Turnaround time: 2-3 weeks

Cannot resize if:

  • Another jeweler has already resized or repaired the ring
  • Ring has been damaged or worn down
  • Design has features that prevent resizing (full pavé, eternity band, etc.)

BETWEEN SIZES? HERE'S WHAT TO DO

If You Measure Exactly Between Two Sizes:

For thin bands (2-4mm):

  • Order the smaller size (they fit looser)

For wide bands (6mm+) or bombe rings:

  • Order the larger size (they fit tighter)

For knuckle considerations:

  • Order the larger size (must fit over knuckle)

When in doubt: Order the larger size. It's easier and less expensive to size down than up.


SIZING FOR GIFTS

Option 1: Sneaky Measuring

Borrow a ring they already wear on the correct finger and:

  • Trace the inside circle on paper
  • Measure the inside diameter
  • Use our size chart

Pro tip: Make sure it's from the CORRECT finger (ring finger if it's an engagement ring).


Option 2: Enlist Help

Ask their:

  • Best friend
  • Sibling
  • Parent
  • Anyone who might know their ring size

Option 3: Adjustable Sizing

Some of our designs can be made with adjustable shanks (ask when commissioning a custom piece).


Option 4: Propose with a Placeholder

Order one size larger than you think, propose with it, then:

  • Use our complimentary resizing service (if you purchased sizing insurance)
  • Or resize for standard fee

Why size up? A too-large ring can be worn temporarily on a different finger until resized. A too-small ring cannot be worn at all.


PRINTABLE RING SIZER (OPTIONAL)

If you want to create a printable ring sizer, this section would include a downloadable PDF with actual-size circles for each ring size that people can print and cut out.

How to use:

  1. Print at 100% scale (no scaling/fitting to page)
  2. Cut out the size circles
  3. Try each size on your finger
  4. Choose the one that fits snugly but comfortably
