How to Choose a Wedding Band: Metal, Width and Fit

Prices checked: October 2, 2026, in our live catalog

Most people are best off with 14k white gold in a comfort fit. 14k is tougher than 18k, because it has less pure gold in it. Comfort fit means the band is rounded on the inside, so it slides over your knuckle more easily. Then you pick a width. That mostly depends on whether it'll sit next to an engagement ring or on its own.

Next to a ring, go narrow, under 3mm. On its own, 5mm or 6mm. Take your time on this part. It's the one you'll notice every time you look at your hand.

That's metal, fit and width, three of the four decisions you make when you choose a wedding band. The fourth is how it sits against your engagement ring, and there's a quick way to check. Look at your ring from the side. If a band could slide in under the stone, a straight one will fit. If not, you'll want a curved band.

Wedding band or wedding ring: is there a difference?

Not really. Jewelers and shoppers use both words for the same thing: the ring you swap at the ceremony and then wear every day.

There used to be a difference. A band was plain metal, and a ring had stones in it. These days, plenty of bands have diamonds. You'll also hear "wedding ring" more often in the UK and Australia.

The engagement ring really is a different thing. It has the center stone, and it comes at the proposal. The band goes on at the wedding and usually sits below it on the same finger. Wondering about the order? There's a little etiquette to it. Here's which ring goes on first.

How the metals compare

If price is going to decide it for you, check the "Relative price" row, fourth one down. It only shows which metal costs more. There's no dollar figure, because the gap between them moves with metal prices.

Decision 1: pick your metal

On a hand, white gold and platinum are hard to tell apart. Expecting platinum to look richer for the extra money? It doesn't. You're paying for a denser metal that ages in a different way.

White gold is gold mixed with other metals, and it's usually plated in rhodium. That plating gives it the bright white surface you see. GIA, one of the big diamond-grading labs, says the rhodium wears away, so the ring needs replating from time to time. Skip it, and you'll start to see a faint yellow tint from the gold underneath.

So white gold comes with a little upkeep, and hardly anyone mentions it when you buy. Don't let that put you off. Replating is a quick job at a jeweler, and it doesn't cost much. There's no set schedule for it. If you're rough on your hands, you'll just need it more often.

Platinum doesn't need replating. GIA says platinum is denser and stronger than gold. In the US, it can only be marked platinum if it's at least 95% pure. It won't stay glossy, though. Over the years it picks up a soft, matte patina. Some people love that. Others have it polished off.

Would a trip to the jeweler for replating bother you more than a matte look that creeps in slowly?

If you've been reading about titanium or tungsten, you won't find those bands at Liori. The width advice here still applies. Resizing them is another story, and the men's wedding band guide has the details.

14k or 18k?

This is the choice most people skip. In the US, white gold mostly comes in 14k or 18k, and the number tells you how much of it is pure gold.

14k is just over half gold. 18k is three quarters. If you like exact numbers, GIA puts them at 58.3% and 75%. Everything else in there is other metals. In white gold, those can include nickel. GIA calls it a common allergen and suggests platinum if you're allergic.

All that extra gold makes 18k softer. In yellow gold, it also gives a slightly richer color. 14k has more of those other metals in it, so it's harder and copes better with the knocks a band takes every day.

For a band you never take off, 14k is the easier pick. Good news if you're going narrow: the petite bands in the width chart below are 14k white gold.

Pick white gold when you'd like a white metal for less than platinum. Pick platinum when nickel is a problem or your hands take a beating. Is your engagement ring yellow or rose gold? Pick that color if you'd like them to match. Mixing works too.

If you're still deciding, there's a full head-to-head on white gold versus platinum. If you've already decided, have a look at the white gold wedding bands and move on to width.

Decision 2: pick your width

Width changes a ring more than anything else. And you can't really picture it from a product page. A few millimeters sounds like nothing. It isn't. The chart below shows why.

You'll see "ctw" under the narrow bands. It means total carat weight: add up every diamond on the band, and that's the number. The bigger it is, the more diamond you're getting. Don't mix it up with karat, the k in 14k. That one's about the gold.

You're looking at real bands, drawn to scale against each other. Up top are the petite diamond bands. Each step wider adds more diamond weight and more metal, so the price climbs from about $700 to about $1,700. At Liori, every band that narrow has diamonds in it.

Below them are four of the plain men's bands. They're 14k gold with no diamonds, and all four are comfort fit. They run from about $2,200 to about $3,800. Why would you pay more for a plain band than for the diamond ones above? Part of it is the gold, since a wider band takes more of it. Each one is also a different design, so width isn't the only thing behind the price. The 8mm, for one, is braided white and yellow gold.

Don't let the "men's" label throw you. They're in the chart because they're the wider bands at Liori that list a width. The 5mm or 6mm advice is for anyone who wears a band on its own.

There are two things the chart can't tell you. First, narrow bands sit better beside an engagement ring, because a wide one crowds the setting and fights it for attention. Second, width looks different on every hand. The same 6mm band looks normal on a broad finger and heavy on a slim one.

Now look at your own hands. Slim fingers or broad? Slim ones suit the narrow end of each range, so 2mm or under beside a ring, or 5mm on its own. Broad ones can carry the wider end.

For width, trying a ring on beats any chart, even this one. If you can get to New York, you can see a few widths in person at the NYC showroom. If you can't, measure a ring you already wear. Then you'll have a width you've seen on your own hand.

Pick a petite band when it'll sit next to an engagement ring and you want that ring to stay the star. Petite here means under 3mm.

Pick 5mm or 6mm when it's the only ring on that finger and you want it to hold its own. Pick 7mm or 8mm when you already own a wide ring and know you like the weight.

Stuck between two widths? Compare them in the wedding band collection or the men's bands. If it's still close, go with the narrower one. What about 3mm or 4mm? That works too, if neither end feels right.

Decision 3: pick your profile

Profile is the shape you'd see if you cut the band in half. It decides how comfortable the band feels. Get it wrong, and you'll keep fiddling with your ring.

The name "comfort fit" doesn't tell you much. Think of the profile as two choices, the inside of the band and the outside. Comfort fit is only about the inside.

A standard band is flat inside, so the full width of metal sits against your finger. A comfort fit band is rounded inside, so only the middle touches you. With less metal on your skin, it slides over a knuckle more easily and traps less moisture underneath.

It also fits differently. At the same size, a comfort fit band usually feels a bit looser, because less of it grips your finger. Try one on before you order if you can, or ask a consultant about your size. A size chart can't tell you how it'll feel.

The outside is simpler. Flat gives you crisp edges and a modern look. Domed rounds off the top for a softer, more traditional feel. Put a domed top on a comfort fit inside, and you get a court band. That's the classic wedding band shape.

Have you worn a ring every day before? If not, start with comfort fit. Pick comfort fit too when your knuckles are on the big side or the band is 5mm or wider. Pick a flat interior when you want it snug and you're fine pushing a bit harder to get it past the knuckle.

To see comfort fit on a real band, look at Liori's plain men's bands. Every one of them has it, from 5mm to 8mm.

What to check before you buy

Here's a quick check that works in any store. Look for these five things on the listing before you pay.

• The karat, as a number. You want to see 14k or 18k. "Solid gold" or plain "gold" doesn't count. If a listing won't name the karat, move on.
• The width in millimeters. Words like "slim" don't tell you anything. You need a number, and it should be right there on the product page. Fair warning: Liori doesn't always manage that. The petite bands and the plain men's bands do list one. For the others, curved bands included, a consultant can give you the number. Ask whether the petite bands are comfort fit too, since their listings don't say.
• The profile. Is it comfort fit or a standard interior? It changes how the ring fits, so it can change the size you order.
• What's under the white finish. Most white gold bands are rhodium plated, and that's normal. The question is what's underneath. A cheaper metal with a white coating isn't white gold, which is one more reason to check the karat.
• Whether it can be resized. A plain gold or platinum band resizes easily. With stones all the way around, a band usually can't be resized at all. With one of those, get the size right the first time.

Decision 4: match it to the engagement ring

Two different things get mixed up here: whether the metals match, and how the band sits against your ring. The metals are just taste. The second one can annoy you every day if you get it wrong.

Start with the metals. Mixing them is normal now. Put a yellow gold band next to a white gold engagement ring, and it looks deliberate.

Now, how it sits. Look at your ring from the side again. If there's room under the center stone, a straight band will slide right in. If the stone sits low, or a halo gets in the way, a straight band can't sit tight against the ring. You'll see a gap, or the band will knock against the setting. Curved bands, also called contour bands, fix exactly that.

At Liori, curved bands start at about $500. Most are 18k, the softer of the two golds, but some come in 14k if you'd like the harder one. If you already know you need one, have a look at the curved bands. They're shaped to sit right up against a setting. For the gaps and the different curved shapes, there's a whole guide on how to match a wedding band to your engagement ring.

His and hers: coordinating two bands

Your two bands don't have to be identical. You and your partner have different hands, and often different taste. You'll probably end up with two different rings. That's fine.

So what makes two bands look like a pair? One shared thing. The same metal is the easiest. The same finish works too, like both matte or both shiny. Or keep it subtle with the same edge on both, like a beaded milgrain edge or an angled, beveled one. Any one of those does it. Two matte bands at different widths still look like a set. Two unrelated rings don't.

Expect your widths to differ too. In the width chart, the petite bands run from 1.7mm to 2.6mm, and the men's bands start at 5mm. Don't pick a width to match your partner's. Each of you should choose for your own hand.

If one of you is buying a men's band, the men's wedding band guide has more on metals, widths and styles. For a band with stones in it, the piece on men's diamond bands covers settings and what they cost. You'll find both kinds in the men's collection.

Plain or diamond band?

Save this one for after the four decisions. Then it's just a question of how much diamond you want, if any. Want a plain band from Liori? Then you're looking at the men's bands, 5mm and up. Anything narrower comes with diamonds.

Stones across just the top half give you a bit of both. That's called a half eternity band. You get sparkle where people see it, and plain metal underneath, where the band takes the wear and can still be resized.

Stones all the way around make it a full eternity band. Choose that, and you probably can't resize it later. This piece on full versus half eternity bands walks you through the choice, and the eternity band price breakdown has prices by metal and stone count.

Lab-grown or mined? They're the same carbon and just as hard, and the big grading labs certify both. Lab-grown costs a lot less. There's a whole write-up on lab versus mined diamonds, too.

Frequently Asked Questions (FAQ)

Short on time? The first four answers follow the four decisions, in order. For anything about your own ring, ask a consultant.

Is white gold or platinum better for a wedding band?

Neither wins outright. Platinum is denser, stays white without plating and costs more. White gold costs less and needs replating now and then. Which matters more to you, the price or the upkeep? For most people, white gold is the easier pick. At Liori, the white gold collection starts at about $700. Curved white gold bands sit in their own collection and start even lower, at about $500.

How wide should a wedding band be?

Beside an engagement ring, go narrow, under 3mm, so the focus stays on the setting. If you'll wear it alone, 5mm or 6mm holds its own. On slim fingers, go with the narrower of the two. Width looks different on every hand, so compare a few in the wedding band collection before you commit.

What does comfort fit mean?

It's all about the inside of the band. A comfort fit band is rounded on the inside, so less metal touches your finger and it slides over your knuckle more easily. At Liori, the plain men's bands are all comfort fit.

Does a wedding band have to match the engagement ring?

No. The metals don't have to match, and mixing them is a normal choice now. Your band should sit right up against the ring, though. A high setting takes a straight band. A low setting or a halo usually needs a curved or contour band.

Do his and hers wedding bands need to match?

No, and identical bands rarely suit you both. One thing in common is enough: the same metal, the same finish or the same edge detail. Your widths will probably differ too, and the men's band guide covers the wider bands.

Should a wedding band be 14k or 18k gold?

For everyday wear, go 14k. By GIA's figures, it's just over half gold, and 18k is three quarters. With less gold in it, 14k is harder and handles daily knocks better. In yellow gold, 18k gives you a slightly richer color. You'll find both in the band collection.
