Band width is the distance across the face of a ring, in millimeters, and it decides how much of your finger the ring covers.
Width, thickness and size are three measurements
Width is the distance across the visible face of the band, from one edge to the other.
Thickness is how deep the band is, from the finger to the outside surface. Ring size is the fit around your finger. A band can look substantial because of its width, its thickness, its profile, or all three.
Each D2 ring page lists the band width in millimeters.
How width reads on the hand
Width is a visual choice more than a rule. Finger length, knuckle size, the scale of your hand and the other rings you wear all change the result.
- Narrow, about 2 to 3 mm: a fine line of metal that leaves plenty of finger visible above and below the band.
- Middle, about 4 to 5 mm: a defined band that shows noticeably more metal but does not take over the finger.
- Broad, 6 mm and up: wide enough to be the main feature of the ring.
Compare three widths, not one
Start with the width you expect to prefer. Then look at one millimeter narrower and one millimeter wider.
- Look from directly above, from the side and in a mirror.
- Look at arm's length as well as up close.
- Close your hand. You should be able to grip normally without noticing the edges of the band.
To test at home, cut a paper strip to each width, wrap it around the finger and look at the result.
When the ring shares a finger
If you wear your ring beside another one, compare the two together on the same hand. The goal is not for the widths to match. It is for their relationship to look chosen.
Widths also add up. A narrow band can disappear beside a larger ring, so ask whether it still reads as its own band.
Width and lab-grown diamonds
On a band set with lab-grown diamonds, the width and the size of each lab-grown diamond are decided together. A wider band can carry larger lab-grown diamonds or more rows. A narrow band keeps the line fine. Check both numbers on the product page.
Choosing your ring size
Width is separate from size, and size comes first. For the most reliable reading, have a jeweler measure your finger in person.
