Wedding ring sizing looks simple on paper — measure the finger, order the band — but two things trip people up: assuming an old engagement ring measurement still applies, and not checking how the new band actually sits alongside a ring you're already wearing.
A wedding band is usually the second ring measured for the same finger, worn alongside the first — and that changes what actually matters when you size it.
For which width to choose when pairing a band with your engagement ring — matching vs. contrasting — see our full ring band width guide. This page focuses on the size and timing side specifically, not width.
Unlike an engagement ring, there's no secrecy pressure to size early — and in fact, sizing too early can work against you.
Close enough to the wedding that your current size is accurate, but with enough lead time for manufacturing, resizing, or engraving if needed.
Try the new band on stacked with your existing ring, not on its own — see the section below on why this matters.
If your weight, activity level, or the season has shifted noticeably since the fitting, a quick re-check avoids a surprise on the day.
A wedding band measured in isolation can still feel wrong once it's actually worn — because in daily life, it sits directly against your engagement ring's setting, prongs, or contoured shape, not on an empty finger.
At your sizing appointment, put both rings on together and check that:
Not automatically. It's the same finger, but engagements often run a year or more, and finger size genuinely can shift over that time from weight changes, age, or simply season and temperature at the time each ring was measured.
Before ordering your wedding band, re-measure rather than assuming — using the same paper strip or string method from our how to measure ring size guide, or by trying on your actual engagement ring right now to confirm it still fits the way it did originally.
Once your size is confirmed, the remaining decision is usually width — matching your engagement ring's profile or deliberately contrasting it. That's covered in full, with a sizing-adjustment table for wider bands, in our ring band width guide.
Anniversary rings — typically added to the stack years after the wedding — follow the same sizing logic as a wedding band: measure the finger as it is now, not from an old record, and try the new piece on stacked with what you already wear daily. If your existing rings still fit comfortably, that's usually the most reliable starting reference for the new piece's size.

About 6 to 8 weeks before the wedding — close enough that your current size is accurate, but with enough lead time for manufacturing or a resize if one's needed.
Usually close, since it's the same finger, but not guaranteed. Finger size can shift over the course of an engagement, so re-measure rather than assuming the old size still applies.
Yes — always try them together at the fitting. A band that fits well on its own can still feel tight or catch on the engagement ring's setting once the two are worn stacked.
This depends on whether you want it to match or contrast your engagement ring's profile — see our full band width guide for the complete breakdown and sizing adjustment table.
No — the same logic applies as a wedding band. Measure your finger as it is now, and try the new ring on stacked with whatever you already wear daily.
This is uncommon if you were sized close to the date, but if it happens, most jewelers can perform an emergency resize quickly — ask about rush turnaround when you order, and see our resizing cost guide for typical pricing.
