Finding the perfect ring size can be nerve-wracking, especially when you want to keep the proposal a secret. But don’t worry, there are several clever and discreet ways to get it right. This guide will walk you through reliable methods to find her ring size accurately without spoiling the surprise, along with some practical tips for measuring your own finger size.

The Best Method: Visit a Jeweller Together

If you can include your partner without giving away your plans, visiting a jeweler is by far the most accurate method. Jewelers use a set of metal ring sizers that come in half-size increments to get the perfect fit. Keep in mind that factors like temperature, time of day, and humidity can cause slight variations in finger size. The ring should fit snugly but still be able to slide over the knuckle comfortably.

If visiting a jeweler isn't an option, you can always order one of our free ring sizers and try it out at home.

Preserving the Element of Surprise

If you’re determined to keep the proposal under wraps, there are still plenty of ways to find her ring size covertly:

  1. Enlist a Friend or Family Member
    Reach out to her close friends, sister, or mom. They might already know her ring size or can casually bring it up in conversation without raising suspicion.

  2. Use a Ring She Already Wears

    • “Borrow” a Ring: Sneak away with a ring that she wears on her left or right ring finger and take it to a jeweler for sizing. If it’s worn on her right hand and she’s right-handed, her left ring finger will be slightly smaller. Reverse this if she’s left-handed.
    • Make an Impression: If you can’t take the ring out of the house, press it firmly into a bar of soap to create an impression. A jeweler can determine the size from the imprint.
    • Trace It: Carefully trace the inside of the ring on a piece of paper using a fine-tip pencil. Hold the ring still and trace as close to the edge as possible. Measure the diameter of your traced circle and match it to a ring size chart.
    • Try It On Yourself: Slip her ring onto one of your own fingers and note where it fits snugly. Visit a jeweler and use a ring gauge to determine the size.
  3. For the Sneaky: Measure While She Sleeps
    If she’s a heavy sleeper, gently slip a ring sizer onto her ring finger and read the measurement. Make sure it fits snugly but can still slide over her knuckle.

What to Avoid

Avoid using string or a strip of paper to measure her finger. These materials aren’t rigid enough and often lead to inaccurate measurements. When in doubt, it’s always better to go slightly larger. If the ring is too big, resizing it is a simple fix, but if it’s too small, it may not fit at all during the big moment.

Pro Tip: The “Go Big” Rule

When in doubt, always err on the side of going slightly larger. It’s much easier to resize a ring that’s a bit too big than one that’s too small.

Good Luck! Finding the right size may seem tricky, but with these tips, you’ll be well-prepared to surprise her with a ring that fits perfectly and a moment she’ll never forget.
