Planning a romantic ring surprise is thrilling, but guessing her ring size can be nerve-wracking. A ring that is too loose or too tight can take away from that magical unboxing moment. Fortunately, you don’t have to ruin the surprise by asking directly. Here are three foolproof, secret methods to get her exact measurement for a Glemes ring.

1. The "Borrow and Trace" Method
If she already wears rings, discreetly borrow one that fits the finger you intend to gift for. Place it flat on a piece of paper and trace the inside circumference with a fine pencil. Alternatively, press the ring firmly into a clean bar of soap to leave a clear impression. Take your paper tracing or soap mold to a local jeweller, or compare the inner diameter against the Glemes Ring Size Chart.

2. Recalibrate During Sleep
If she is a deep sleeper, wait until she is fast asleep. Take a soft piece of string or a narrow strip of paper, wrap it gently around her ring finger, and mark the exact point where the ends meet with a pen. Measure that length in millimeters to find her perimeter.
3. Enlist Her Best Friend
Her closest friends often know her ring size, or they can bring it up naturally in conversation during a shopping trip without raising suspicion. When in doubt, opt for Glemes Adjustable Rings, which feature open-back bands that accommodate various sizes comfortably!
