Ring Sizing Chart & Fit Guide: How to Find Your Perfect Fit, From Home

Sizing & Fit Guide: How to Find Your Perfect Fit, From Home

“What if it doesn’t fit?” It’s the question we hear most from anyone buying jewelry online.

Here’s how to measure your ring size at home, our US/UK/EU size chart, and what to know about necklace lengths and earring closures before you order.

How to Measure Your Ring Size at Home

You don’t need a jeweler’s visit to get an accurate measurement. 

Here’s the string (or paper strip) method:

1. Wrap a piece of string, thread, or a thin strip of paper snugly around the base of your finger — the part you’ll wear the ring on.

2. Mark the point where the ends meet, or cut the string at that point.

3. Check the fit — it should sit comfortably, not so tight it gets stuck, and not so loose it slips off.

4. Measure the length in millimeters using a ruler. That number is your finger’s circumference.

5. Match it to the conversion chart below to find your size. A couple of notes that make a real difference: For thicker or wider bands — think statement rings or pavé styles — consider sizing up slightly, since more metal touching the finger reduces how much it can flex. If you land between two sizes, size up rather than down.

This chart reflects standard international ring sizing conventions. For a piece-specific fit, we recommend confirming with a physical ring sizer alongside your string measurement.

Necklace Length & Closures

Rings aren’t the only pieces where fit matters. Several PSYLISH necklaces; including our Evil Eye and Diamond Drip styles, use a lariat closure with a sliding bead, which lets you set your own length rather than being locked into one size. On these styles, the product page notes the maximum adjustable length (commonly up to 18”, 21”, or 24” depending on the design), so you can wear it higher and closer to the collarbone or lower as a layering piece.

Other necklaces use a snap closure; a secure clasp mechanism at the back, rather than an adjustable slide.


Quick tip for layering: if you’re stacking multiple necklaces, look at each piece’s stated

length so they sit at staggered heights rather than overlapping at the same point.

A Few Sizing Notes on PSYLISH Pieces Specifically

  • Available size ranges vary by design. Some styles — like our sculpted pavé and statement pieces — are available across a set range (for example, US 5.5–7.5), noted directly on each product page.
  • Need something outside the listed range? Email us at info@psylish.com for a custom size request.
  • Solid gold vs. vermeil fits differently. Our 18K and 14K solid gold pieces hold their shape precisely; our FREY collection (18K gold plating over 925 sterling silver, with a thick 3-micron layer for lasting brilliance) wears similarly but is worth double-checking against the string method above, since plated bands can feel marginally different in hand.
  • Ordered the wrong size? We’re reachable 24/7 on WhatsApp and by email to help sort out a resize.

Earring Closures, Explained

Since we get sizing-adjacent questions about earrings too, here’s a quick primer on the closures across our Studs, Huggies, Hoops, Ear Cuffs, and Dangly styles:


  • Hinged / click-closure — common on huggies and small hoops; the hoop itself opens on a hinge and clicks shut, so there’s no separate backing piece to lose.

  • Ear cuffs — worn without a piercing, gripping the outer ear instead of threading through the lobe, which is why they come in one adjustable fit rather than a sized range.

  • Post and back — the traditional stud setup, secured with a friction back.

A Quick Glossary — Vocabulary You’ll See on Our Product Pages

  • Illusion setting — a technique where smaller diamonds are grouped and set to visually merge into what reads as one larger, more brilliant stone.
  • Pavé — small diamonds set closely together across a band or surface, creating a continuous sparkle.
  • Lariat — a necklace closure using a sliding bead along the chain, letting you adjust the wearable length yourself rather than fastening at a fixed point.
  • Snap closure — a secure clasp mechanism used on necklaces that aren’t adjustable via a lariat slide.
  • Hinged / click-closure — the built-in opening mechanism on huggie earrings and small hoops.
  • Huggie — a small hoop earring designed to sit close against the earlobe rather than swing freely.
  • Ear cuff — a no-piercing-required earring that grips the outer ear.
  • 18K Solid Gold — durable, tarnish-resistant gold used across our core collections.
  • Gold Vermeil — 18K gold plating over 925 sterling silver, as used in our FREY collection.
  • SI Clarity — the clarity grade used across our natural diamonds, meaning “eye-clean” —inclusions aren’t visible to the naked eye.
  • Zambian Emeralds — one of the natural gemstone origins featured across select PSYLISH pieces.
  • Factory to Cart — our production model, where we manufacture in-house and sell direct, cutting out the middleman markup typical of traditional fine jewelry.

Sizing FAQs

  • Does ring width affect sizing? Yes. Wider or thicker bands (statement styles, sculpted pavé) fit more snugly than thin bands at the same labeled size, since more surface area touches the finger. Size up if you’re between two sizes and choosing a wider design.
  • Can I get my PSYLISH ring resized? Reach out to us directly with your order details —we’re happy to help figure out the right path.
  • What if I’m ordering as a gift and don’t know their size? Borrow a ring they already wear on the intended finger and measure its inner diameter against the chart above, or size slightly larger — resizing is easier than replacing.
  • Do all PSYLISH rings come in the same size range? No — each product page lists the exact sizes available for that specific design, since some settings are more limited than others.
