You need a fit that slides on smoothly over the knuckle but takes a little resistance to come back off. Too tight, and it won't clear the knuckle at all. Too loose, and gravity does the rest.
Sizing can be trickier than it sounds. If your knuckle is noticeably larger than the base of your finger, and a lot of us are exactly that, split the difference between the two measurements. Our Jewelry Size Guide walks through exactly how to measure at home, whether you're sizing your own finger or measuring a ring that already fits well, along with the full US ring size chart.
One more tip that trips people up: measure at a normal body temperature. Stay cool, don't measure when you're hot, and maybe skip sizing yourself right after a night out, since cocktails and swollen fingers don't exactly mix. When in doubt, size up rather than down. If you'd rather skip the paper-strip method altogether, you can order our Ring Sizer and get a reading that's about as accurate as an at-home measurement gets.
How to Make a Ring Smaller at Home
If you're not ready for a permanent resize yet, or you're waiting out a seasonal fit change, there are a few safe, reversible ways to keep your ring secure in the meantime.
- A ring size adjuster: small, clear coils or sizing beads that fit inside the band to take up extra space. They're inexpensive, reversible, and don't touch the ring's structure.
- Stacking rings: wearing a correctly fitted ring on either side of the loose one creates a barrier that keeps it from sliding off, while doubling as an intentional-looking stack.
- A ring guard: a small clip or spring insert that snaps onto the band from underneath, tightening the fit without any permanent change to the ring.
What we'd steer you away from: tape wrapped around the band might feel like a quick fix, but it can damage the metal finish over time and leaves a sticky residue that's a pain to remove. These at-home options are a fine short-term bridge, but they're not a substitute for a proper resize if the fit issue is here to stay.
When to Get It Professionally Resized
If the loose fit isn't seasonal and isn't going away, professional resizing is the safest long-term fix. Most rings can be sized up or down by about 1 to 1.5 sizes without compromising the setting or the integrity of the band. Beyond that range, the structure of the ring may need more significant rework, so it's worth having a conversation with your jeweler about what's realistic for your specific piece.
At Ring Concierge, every engagement ring is handcrafted right here in NYC, and the first resizing on your engagement ring is complimentary within one year of your purchase date. Bespoke bridal pieces also come with a complimentary lifetime warranty that covers manufacturing defects, and we're always happy to talk through a resize. One thing worth knowing before you go anywhere else: having any RC piece resized or repaired by an outside jeweler will void that warranty, so if your ring came from us, come back to us first.
Not every ring can be resized at all. Eternity bands and bangles, for example, typically can't be adjusted, since the diamonds run the full circumference with no plain metal section left to add or remove from. If you're not sure whether your specific setting is a candidate, that's a quick and worthwhile question to ask before committing to any fix, temporary or permanent.
