How to Choose the Perfect Ring Width and Why It Matters

Stone and metal type aren't the only elements to factor in when choosing an engagement ring or wedding band: There's also ring width. "Ring width refers to how wide the band of the ring is when the person wearing it looks down at their finger," says Angie Kennedy, VP of product innovation at Zales. The width is measured in millimeters and typically ranges from 2mm to 12mm. (Note that ring width is totally different from, but can affect ring size; your ring size may alter slightly for different band widths.)

Just like with stone shapes, diamond settings and metal colors, trends in ring width come and go. You'll know it when you see it: For engagement rings, wider cigar bands that offset the stone are trending. For the wedding bands that complement, it's the opposite. "Right now, we are seeing a trend of thin bands with thin stones, many incorporating diamond cuts such as marquise, oval and pear," Kennedy says. "The dainty, minimalist look is one many brides gravitate toward right now, though these trends change quickly."

Regardless of your style preference, width should also be considered for other reasons. Here, Kennedy explains why width is an important dimension and offers some insight into choosing your wedding ring width.

Why is Ring Width Important?

Ring band thickness is not just about style. "The width of the ring determines a lot of factors, including comfort for the wearer and durability of the ring," Kennedy says. "It is important to choose a style based on your needs." Wider bands are typically more durable, for instance, and daintier bands are often better suited to smaller stones. Note that, especially in the case of engagement rings (as opposed to wedding bands), width is sometimes listed online, but Kennedy recommends shopping in-store to learn more.

Should Engagement and Wedding Band Be the Same Width?

It depends, and there's no right answer. "While traditionally people opted for engagement rings and wedding bands in the same width, many people today prefer to mix and match for a more personalized touch," Kennedy says. "A current trend we're seeing is to mix bold bands with thinner engagement rings, especially as traditional and classic solitaire engagement rings continue to rise in popularity again." But, ultimately, it's up to the wearer (or the proposer!). "There is no 'one size fits all' approach," Kennedy says. "The choice should reflect individual tastes and styles, making each set unique to the couple."

How to Choose a Band Width for an Engagement Ring

If you're creating a custom engagement ring—or even if you're purchasing a pre-designed ring—you have plenty of options when it comes to engagement ring band width. "Women commonly choose engagement rings between 1.5mm and 4mm, such as this one from Zales," Kennedy says. (People often wonder if a 1mm ring is too thin, and the answer is probably yes; see below as to why.) Here, Kennedy offers tips for choosing the right engagement ring thickness in mm.

Balance the Stones

"For engagement rings, the main factor to consider is the carat weight of the center stone," Kennedy says. "While a thinner band may be easier to put on and feel more comfortable, it often can't support the weight of a larger stone and is more prone to spinning around the finger." A good rule of thumb: The bigger the diamond, the wider the band.

Consider Aesthetics and Hand Shape

You want to love your ring, and so how it looks on your finger should absolutely play a role (though Kennedy warns against letting that be the only factor considered). "Aesthetic preferences can play a part in deciding," she says. "Typically, those with smaller hands prefer the look of a narrow band, while broader hands are well suited for wide band engagement rings. However, this is just one factor to consider, while the more important factors are comfortability and durability."

Try It On

It may be controversial, but "trying rings on in person is the best way to decide what type of band you should get, as your ring size will change based on the width of the ring," Kennedy says. "Some couples prefer to shop together, while others prefer to be surprised." If you're the like-to-be-surprised type, go ring "shopping" with your girlfriends sometime in advance of a proposal to get a feel for what you like on your finger; that way, they can pass on the clues to your significant other.

How to Choose a Band Width for a Wedding Ring

On average, Kennedy says, women tend to select wedding bands between 2mm and 5mm (here's one she loves). Men's ring width tends to be wider, averaging around 6mm to 8mm. "It ultimately comes down to personal choice," Kennedy says.

Talk to a Jeweler About Metal Types

"When selecting a wedding band width, several factors should be considered, including metal type," Kennedy says. "At Zales, we have minimum width requirements that we will not go below to make sure the quality standards are met and bands do not bend." Platinum is a stronger metal than gold, for instance, and is more durable for narrower bands.

Decide if You Want the Bands to Match

Unlike with the engagement ring, which is typically kept secret, couples can go together to try on the matching wedding bands. This is the best time to decide if you want your engagement ring and wedding band widths to match, as you can try the band on with your engagement ring. "For those who want something really special and unique, Zales offers services where you can create your own custom engagement rings and wedding bands that speak to your personal style," Kennedy says. Plus, picking wedding bands together makes for a fun day date, and you can see how your bands look with each other's, as well.

Consider Your Lifestyle

This is an important one. "Overall, a thicker band can better withstand the wear and tear of daily activities compared to a thinner one," Kennedy says. If you're not someone who wears your ring daily or takes it off for activities that may contribute to wear and tear, a thinner band works well.
