How to find out your partner’s ring size without them noticing? 💍🤫

You’ve got the design, the perfect stone, and even the proposal idea all figured out — but there’s one problem: you don’t know your partner’s ring size.

Es importante tener claro ese dato, para que todo salga perfecto en ese momento!

Choosing an engagement ring is an exciting and meaningful moment. But one of the biggest challenges? Getting the size just right.

A ring that’s too tight can be uncomfortable, and one that’s too loose can easily fall off. That’s why we’ve created this article to share a few simple ways to figure out the perfect ring size — so this special moment can be unforgettable in all the right ways.

Methods to Measure the Ring Size

1. Use a Ring They Already Own

If your partner already wears rings, try borrowing one that fits well — ideally one they wear often, since it’s more likely to be a good reference.

• Place the ring on a ruler and measure the inside diameter in millimeters.

• Use a size chart (like the one we’ve included below) to match the diameter to the correct ring size.

• Make sure the ring is worn on the same finger the engagement ring will go on — usually the ring finger of the left hand.

2. Ask a Friend or Family Member for Help

If you’re planning a surprise proposal, a close friend or family member might already know their ring size — or be able to help you figure it out without raising suspicion.

A sister, best friend, or even their mom can be a great ally!

3. Use a Ring Sizer

Another option is to get a ring sizing tool, available at jewelry stores or online.

If your partner has a ring they don’t wear daily, you could borrow it for a day — and at Pedra, we’ll help you measure it without the need to purchase anything.

💡 Extra Tips

• Consider time of day and temperature: Fingers can swell in the heat and shrink in the cold. The best time to measure is at the end of the day, when the finger is at its natural size.

• When in doubt, size up: If you’re between two sizes, go with the slightly larger one — it’s easier to resize a ring that’s too big than one that’s too small.

This chart will help you understand how ring sizing works. Just take two measurements from the inside of the ring — the diameter and the circumference — and you’ll be able to find the correct size.
