Ring Sizing

No tools like ring sizers or mandrels? No problem!

 

Three Sizing Methods:

 

• Wrap a piece of string around your finger where the ring will sit

  • Mark or cut where it overlaps, lay it flat and measure in millimeters

  • Divide that number by 3.14 to get your diameter, then compare to a US ring size chart.

• Grab a ring that fits the exact finger

  • Measure straight across the inside (side to side) in millimeters

  • Compare that number to a ring size chart

• Visit a jeweler if you want zero doubt (recommended)
   

Keep in mind:

• A ring worn on the right hand may not fit the same on the left and vice versa

• Consider whether your current ring fits great, snug, tight, or loose

• "It kinda fits" is not a size

• Think about what can affect your size (see below)

Measurement Basics

Millimeters (mm) is the global standard for jewelry sizing.
One inch = 25.4 mm.​​​

What Actually Affects Ring Size

• Temperature Changes

  • Fingers swell in heat and shrink in cold

  • Size can fluctuate up to a full size

  • Always measure in moderate, comfortable conditions

  • *Measure when your hands feel "normal"

• Time of Day

  • Fingers are typically smaller in the morning, larger in the evening

  • Measure in the late afternoon or early evening, when they're at their average size

  • *Late afternoon or early evening is "normal"

• Activity & Lifestyle

  • Exercise, salt, travel, hormones - everything matters!

Ring Width & Size Adjustment

• Thin Bands (1-3 mm)

  • Minimal contact with the finger

  • Typically run true to size

  • No adjustment needed

  • Least affected by finger size fluctuations

​

• Medium Bands (4-6 mm)

  • Require sizing up by a half size

  • Creates more resistance when sliding over the knuckle

  • More contact at the finger base affected by size fluctuations

​

• Wide Bands (7 mm+)

  • Often a full size or more above thin ring measurements

  • A wider band covers more of the finger and usually requires additional room for comfortable all-day wear

​​

If using a thin ring as a reference for a wide band, plan to size up.

When to Size Up

Choose the larger half size if:

• Your fingers fluctuate with temperature

• You are between sizes

• The ring must pass over a larger knuckle

• You switch fingers frequently (I do!)

Important Do's & Don'ts

Do:

• Measure multiple times over several days

• Measure in the late afternoon or evening

• Check your knuckle (seriously)

• Think about the band width

• Visit a jeweler if you want zero doubt (recommended)

 

Don't:

• Guess

• Measure cold fingers

• Assume all rings fit the same

Bracelet Sizing

Bracelet sizing is simple:
 

• Measure your wrist snugly at the wrist bone.

• Add your comfort fit.

  • Snug Fit: + ½ inch

  • Comfortable Fit: + ¾ to 1 inch (standard)

  • Loose Fit: + 1 to 1¼ inches

     

Most Twisted ZenStone designs are cuffs with approximately 1 inch added for overlap; designs will vary.

Be mindful that while pieces may adjust, constant bending equals metal fatigue.

Necklace Length

• Choker (14-16") - Sits at or above the collarbone

• Princess (18") - Most common; sits just below the collarbone

• Matinee (20-24") - Falls near the top of the bust

• Opera (26-34") - Falls at or below the bust

• Rope (36+") - Worn long, doubled, or knotted

Choker Tip (Do This Right)

• Measure around the base of your neck where it will actually sit

• Stand normally; don’t pull tight and don’t slouch

• Add ½ to 1 inch so you can breathe

Final Check Before You Order

• You've chosen the exact finger the ring will be worn on

• You measured more than once (or went to a jeweler!)

• You accounted for your knuckle

• You adjusted for band width

• You chose your bracelet fit intentionally
   

You’ll receive a photo of your finished piece on a mandrel confirming size before shipment.
