Measure at room temperature

Finger size can change with temperature, so measure when your hands are comfortable.

Measure two or three times

For the most accurate result, take at least two measurements and compare them.

Comfort is key

Your ring should feel secure while still sliding comfortably over the knuckle.

Between two sizes?

Choose the larger size in most cases for a more comfortable fit.

Ring Size FAQ

What ring sizing system does Buvea use?

Buvea ring selections are displayed in US sizes.

Is 17 mm my diameter or circumference?

A measurement of around 17 mm is typically the inside diameter of a ring. Finger circumference is usually much larger.

Should I measure the inside or outside of an existing ring?

Measure only the inside diameter. Measuring the outside includes the thickness of the metal and can lead to an incorrect size.

Can every Buvea ring be resized?

Resizing depends on the design. Full eternity rings and certain design-specific styles may have resizing limitations.

My measurement is between two sizes. Which should I choose?

For most standard-width rings, the larger size is usually more comfortable.

I measured 5.5 cm around my finger. What should I enter?

5.5 cm equals 55 mm. Enter 5.5 and choose cm, or enter 55 and choose mm.
