How to Secretly Get Ring Size When You Live Together
You already know where she keeps her passport, which drawer her tights live in, and exactly what time she gets home on a Tuesday. That's the problem. Planning a proposal is hard enough when you have your own apartment to hide things in. When you share every square foot of the place with the person you're trying to surprise, "secret" starts to feel like a technicality.
The good news: living together doesn't actually make a secret proposal impossible — it just means the obvious moves (a drawer, a coat pocket, a "safe" spot in the closet) are off the table. You need a plan that works with the fact that she notices things, because she does, and because that's exactly the kind of woman worth planning this for.
Why living together actually changes the math
Most proposal advice assumes two separate apartments, a getaway car's worth of privacy, and a mother-in-law who can hold a ring hostage for six weeks. None of that applies when you split rent. Every hiding spot in a shared home is a spot she also has access to — which means the standard advice (sock drawer, glove box, the top shelf of the closet) mostly describes places she'll find the ring while looking for something else entirely. The fix isn't smarter hiding. It's shifting some of what you'd normally hide inside the apartment to somewhere outside it, and being deliberate about the two things that actually require secrecy: her ring size, and the ring itself.
How to secretly get ring size when you can't just ask
This is the part that trips up most first-time planners, and living together makes it both easier and harder — easier because you have constant access to her jewelry, harder because she'll notice a missing ring faster than a missing sock.
Borrow a ring she already wears on that finger
The single most accurate method: take a ring she already wears on her right hand (never the left — different finger, different size) while she's in the shower or asleep, and either take it to a jeweler for sizing or trace its inside diameter on paper. Put it back within the hour. If she has a ring on her left hand already — a fashion ring, not a wedding band — even better, since that's the exact finger you need.
The string or paper trick
If borrowing a ring feels too risky, a thin strip of paper or a piece of string wrapped snugly around her ring finger while she's asleep works almost as well. Mark where it overlaps, measure it in millimeters, and compare it to a standard ring size chart. It's not perfect, but it's close enough that a jeweler can adjust from there.
Enlist someone she trusts
Her sister, her best friend, or her mother can casually bring up rings in conversation, invite her to try some on "for fun," or simply ask her directly — women tend to be far less suspicious of another woman asking about jewelry than they are of a boyfriend suddenly caring about ring sizes. This is also the moment to have that person help you figure out her actual taste, not just her size, so you're not guessing at style on top of guessing at fit.
Worth knowing: Most rings can be resized up or down by half a size after the fact without much trouble, so you don't need to be exact — you need to be close. A slightly loose ring is a minor inconvenience. A ring that won't go past the knuckle is a moment nobody wants at the proposal.
Where to actually hide the ring when you share every drawer
Once you have the ring, the question of where to hide an engagement ring gets a lot more literal when there's no spare apartment involved. The honest answer is: mostly, don't hide it at home at all.
- Your workplace desk drawer or locker. She has no reason to be there, and it's the single most underused hiding spot for exactly that reason.
- A trusted friend's apartment. Hand it off entirely. You can't accidentally leave a ring somewhere it can be found if it isn't in your possession.
- A safety deposit box or a small home safe you control. If you do keep it at home, a low-cost lockbox tucked inside something unglamorous — a toolbox, a case of old cables — beats any drawer she might reorganize on a whim.
- Your car, in the glove compartment or under the spare tire cover. Works well if you're the one who drives most often and she rarely opens either.
The places to actively avoid are the ones every generic guide recommends: the sock drawer, inside a shoe, taped under furniture. Anywhere that shows up on the first page of a search for how to hide an engagement ring is a place a curious partner has already thought to check.
Choosing a ring she'll love without her ever seeing it in person
Here's where a lot of partners overthink it: you don't need to nail every detail of her exact dream ring. You need a ring that's genuinely beautiful, unmistakably well-made, and doesn't require you to walk into a jewelry store and explain your entire financial plan to a commissioned salesperson. Gemiros' rings are built exactly for this moment — 925 sterling silver, moissanite and simulated diamond stones cut and set to catch light the way a jewelry-store diamond does, without needing you to justify a markup that exists mostly to fund advertising you've already seen a hundred times on Instagram. A ring that looks like it cost $15,000 or higher, at a price that doesn't require a loan, means the only pressure left is picking a style — not affording one.
The Soleil Ring
A round-cut solitaire on a pavé band — the safest bet if she leans classic and you'd rather not gamble on a shape she's never mentioned wanting.
Shop The Soleil Ring →If she's dropped hints about wanting something with more presence — a sharper silhouette, a stronger opinion — a princess cut reads as confident without tipping into unfamiliar territory for most first-time buyers.
The Lennox Ring
Sharp, geometric, and a 2-carat presence on a pavé band — for the partner whose girlfriend has strong opinions about clean lines.

Managing the parts you can't fully control
Living together means she'll notice a change in your mood before she'd notice a missing ring. A few practical habits help more than any hiding spot:
- Use a separate email for order confirmations and delivery notifications, so a shipping update doesn't pop up on a shared inbox or a phone she sometimes borrows.
- Have packages sent to your workplace rather than home, especially if you're usually the one who grabs the mail anyway — a sudden change in that habit is more suspicious than the package itself.
- Keep the timeline realistic. Rushing to hide a ring the same week it arrives is when mistakes happen. Give yourself breathing room between delivery and proposal.
- Decide in advance what you'll say if she does ask. A prepared, casual answer beats a visible panic every time.
None of this requires elaborate planning software or a secret second phone. It requires treating the ring the way you'd treat any other surprise gift — kept out of the house, ordered quietly, and revealed on your terms rather than discovered on hers.
Quick Takeaways
- Borrowing a ring she already wears on the correct finger is the most accurate way to size her secretly.
- The string-and-ruler method works as a reliable backup if borrowing a ring isn't possible.
- Keep the actual ring somewhere outside the shared home — a workplace, a trusted friend, or a lockbox you control.
- Avoid every "creative hiding spot" a quick search would also surface — she may have seen the same list.
- Order online, route deliveries away from a shared inbox or mailbox, and give yourself time between delivery and the moment itself.
Frequently Asked Questions
How do you discreetly find out someone's ring size?
Borrow a ring she already wears on her right ring finger and take it to a jeweler, or trace it on paper, while she's asleep or in the shower. If you can't borrow a ring, a string or paper strip wrapped snugly around her finger and measured in millimeters gives a close estimate a jeweler can work from.
Can I use my phone to measure a ring size?
Some sizing apps use your phone's camera and a reference object, like a credit card, to estimate a ring's inner diameter, but the accuracy varies. Treat any app result as a starting estimate rather than a final size, and confirm with a physical method if you can.
Where do people usually hide an engagement ring at home?
Most guides suggest a sock drawer, a coat pocket, or taped under furniture — which is exactly why those spots no longer work well. If you live together, the safer move is keeping the ring somewhere outside the shared space entirely, like a workplace drawer or with a trusted friend.
What's the safest way to keep a proposal secret when you live together?
Remove the ring from the equation as much as possible — order it with a separate email, have it delivered somewhere other than home, and store it outside the apartment until you're ready. The fewer secret objects inside your shared space, the fewer chances she has to stumble onto one.
Living together doesn't make a proposal less romantic — if anything, it makes the eventual reveal land harder, because she genuinely didn't see it coming despite living three feet from where you kept your secret. Get the size close, keep the ring somewhere she'll never think to look, and let the rest of the planning be the fun part.
