Stealth Ring Sizing Guide

The Ultimate Stealth Ring Sizing Guide

How to find her exact fit without ruining the surprise.

The Secret Methods (Preserve the Magic)


  1. The 'Borrow' Technique (Highest Accuracy): Temporarily borrow a ring she currently wears on her left ring finger. Place it on a piece of paper and trace the inside circle with a sharp pencil.

  2. The Soap Impression: Press one of her existing rings
    firmly into a bar of soap to create an exact mold. Wipe the ring clean
    and measure the inner diameter of the impression.

  3. The Inside Man: Enlist her best friend or sister. They
    often already know her size or can casually find out during a "just for
    fun" jewelry shopping trip.

Standard Sizing vs. Secret Sizing


  • Standard Sizing (The Foolproof Way): Using a professional metal ring sizer or our complimentary sizing kit. Pros: 100% accurate. Cons: Completely ruins the surprise.

  • Secret Methods (The Romantic Way): Using the tracing or soap methods. Pros: Keeps the proposal a complete secret. Cons: Slight risk of being 0.5 sizes off.

The Verdict: If you want a surprise proposal, use the secret methods. Pro tip:
It is always easier for a jeweler to size a ring down than to size it
up. If your stealth measurements fall between two sizes, choose the
larger one.
