Earring Size, Weight & Comfort

Size, next to US coins

Coins are drawn to scale with each other. Sizes on product pages are height x width in mm and inches.

Weight & comfort

We weigh one earring, not the pair. US coins weigh a fixed amount, so they make a handy reference.

2. Lightweight2–4.5 gAbout one or two dimes. Easy to wear for most of the day.
3. Medium4.5–7 gAbout a nickel (5 g) or a quarter (5.67 g).
4. Substantial7–10 gAbout a quarter and a dime, up to two nickels.
5. Heavyweightover 10 gMore than two nickels. Among our heaviest.

Bangle & cuff

The wrist range it fits, e.g. “Fits wrists about 5.5”–7””.

How to measure

Wrap a tape measure, string or paper strip around your wrist just above the wrist bone, mark where it meets and measure it with a ruler. If you use a printable sizer, print it at 100% scale.

For a chain bracelet, add about 0.5” to your wrist size for a close fit or about 1” for a relaxed fit. An extender chain widens the range.

Ring Size & Fit

We make whole US sizes only (no half sizes). Each product page shows the sizes available for that ring.

How to measure

Measure the inner diameter of a ring that fits the same finger, or wrap a strip of paper around your finger and compare the circumference with the table. Measure at the end of the day when your fingers are warm, and make sure the ring can pass over your knuckle.

Wide bands (for example 8 mm) fit more snugly. If you are between sizes, choose the next size up. Tungsten rings cannot be resized, so please check your size before ordering.

If you use a printable ring sizer, print it at 100% scale. Measurements are approximate.
