Ring, Bracelet, Necklace & Earring Size Guide | Free Jewelry Sizing Tool
The Measuring Studio

Find the fit before it arrives.

Four simple tools to measure rings, bracelets, necklaces, and earrings from home — no jeweler required.

Precision, at home

Every measurement below converts instantly to real sizing — the same way a jeweler’s loupe brings the fine print into focus.

Screen calibration
Match the box to a real card so the black dial reads true-to-size.
CARD
Hold any standard card (bank card, ID, gift card) up to this outline. Use the buttons until the outline matches the card exactly.

01 — Ring Sizer

Measure a ring finger

Wrap a strip of paper or string around the finger, mark where it overlaps, then measure that length in millimeters.

Circumference (mm)
Diameter (mm)
Indian size  ·  US  ·  UK  ·  EU
17.2 mm ⌀ · slide to match an existing ring laid flat on screen
  1. Cut a 6cm strip of paper or a piece of non-stretch string.
  2. Wrap it snugly around the base of the finger, where a ring normally sits.
  3. Mark the point where the ends meet or overlap.
  4. Measure that length with a ruler in millimeters and enter it at left.

No string handy? Lay a ring you already own flat on the screen and grow or shrink the black dial next to it until the inner edges match.

02 — Bracelet & Wrist Sizer

Measure a wrist

Wrap a tape measure or string just below the wrist bone, then choose how the piece should sit.

Snug

( inches)
55.0 mm ⌀ · match to a bangle’s inner opening
  1. Locate the wrist bone and wrap your tape just below it.
  2. Keep the tape snug but not tight — you should be able to slide one finger under it.
  3. Choose a fit style: snug sits close, comfort has gentle movement, loose drapes lower.
  4. Read your recommended bracelet length at left.

Own a bangle already? Rest it on screen and grow the black dial to match its inner circle instead of measuring your wrist directly.

03 — Necklace Length Guide

See where each length falls

Tap a length to see where it sits, based on an average neckline.

Choker · 14–16″
Princess · 17–19″
Matinee · 20–24″
Opera · 28–36″
Rope · 36″+

Choker

Sits directly at the base of the neck. Pairs well with open collars, off-shoulder necklines, and layering with a longer chain.

04 — Earring Drop Guide

Choose a drop length

Earrings aren’t measured on the body — this is a quick reference for how drop length reads on the face.

Stud — 0″

Sits flush at the earlobe. Best for everyday wear and a clean, minimal look.

Huggie / Short Drop — up to 1″

Grazes the jawline on most face shapes. Versatile for both day and evening.

Mid Drop — 1″–2″

Falls between the jaw and shoulder. Elongates the neck; flatters rounder face shapes.

Statement / Long Drop — 2″+

Reaches toward the shoulder. Best with hair worn up or pulled back.
