Sizing Guide — The Twisted ZenStone™

Ordering jewelry online should not be a guessing game. Accurate sizing matters, and customers are responsible for confirming their measurements before ordering. The guide below is here to help you choose as confidently and accurately as possible.
​​​​​​​​
​
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.
Incorrect sizing is the responsibility of the customer and is not considered a defect.
