Why Ring Thickness Matters (and Why We Haven't Made Ours Thinner)

When people shop for a wedding band, they usually ask about width: 4mm or 6mm, narrow or bold. Width is what you see across the room. Thickness is what you feel every day, and it has more to do with how a ring holds up over a lifetime than almost anything else about it.

Width and thickness are not the same thing

Width is how far the band runs along your finger, measured across the top.

Thickness (jewelers also call it depth or profile) is how much metal sits between the inside of the ring and the outside surface. If thickness varies, it's measured at the thinnest point, usually the underside of the band, because that is where a ring wears and where it gives way first.

Weight follows from both. Two bands of the same width can differ by several grams because one simply has more metal in it, and you notice that difference the moment you put the ring on.

What thickness to look for

There is no single standard, but jewelers' guidance falls into a fairly consistent range:

  • About 1.2 to 1.4mm: light. Comfortable and economical, but more prone to bending out of round, especially in wider bands.
  • About 1.5mm: a common minimum for a ring worn every day, particularly by anyone who works with their hands.
  • About 1.7 to 2.0mm: the range most jewelers recommend for everyday wear, balancing comfort with resistance to bending.
  • 2mm and above: substantial. You feel the ring, and it keeps its shape.

The inside of a band shapes how it feels on the finger.

Wider bands need more thickness to stay rigid; a wide band that is also thin can flex like a strip of foil. The inside matters too: a gently rounded interior, often called a comfort fit, lets a thicker band slide over the knuckle and sit easily.

Metal prices, and the temptation to go thinner

Gold and silver set record prices through 2025 and into 2026. The jewelry trade has responded in predictable ways: lighter designs, hollow chains, lower-karat gold, and pieces engineered to look the same while using less metal. Some of that is sensible; a lighter piece can make fine jewelry affordable for more people.

We haven't changed our approach. The designs we create in our Andover workshop keep a solid, comfortable weight. We have not thinned our bands or shaved metal from our crosses and pendants to hold a price, because the whole point of a piece like this is that it lasts. A wedding band gets knocked against car doors, gripped around tools and worn through decades of dishes and yard work. It should come through all of that still as round as the day you were married.

We hope our pieces are cherished for a lifetime and then passed down, so that a new generation can cherish them in turn. Our designs are made with that intention - a piece can only become an heirloom if it is made to last long enough to be handed on.

Not just rings

The same thinking applies across our work. Our Celtic crosses have real depth to them, with a reassuring weight in your hand rather than the feel of a flat cut-out. Pendants hang well and sit flat because there is enough metal to give them some heft. Bails and jump rings are sized to carry the piece for years of everyday wear.

When you hold one of our pieces, you'll feel the difference.

Made to be worn, and handed down

Every new piece from our studio carries our one-year guarantee, and repairs are done by the same craftsmen who make our jewelry, on the same benches. Rings come with free resizing within 90 days of purchase (the first sizing; sale and discontinued rings excepted); see our ring sizing chart to get it right the first time.
