Ring sizing · printable
Print a ring sizer at exact scale.
Two ways to size at home, both on one sheet. A 100 mm ruler at the top confirms your printer didn't scale the page. If unsure, request a free plastic mail-a-sizer or book a fitting.
Pick the method that fits your home setup.
- Method
String and ruler
Wrap a thin string or paper strip snugly around the finger. Mark where it meets, lay it flat against a millimeter ruler, then match the circumference to a US size.
Best for measuring a finger directly.
- Method
Existing ring
Place a ring that already fits the finger over the overlay circles on the printable sheet. The circle whose inner edge meets the inside of the ring is the size.
Best when the wearer cannot try on.
- Method
Mail-a-sizer
Free plastic ring-sizer in a finger-sweep band, mailed within two business days. Includes a $10 credit toward any purchase.
Best for surprise rings or precise fits.
How to use the printable sizer
Print at 100%
Choose Print, set Scale to 100% (or Actual size). Do not use Fit to page. Hold a ruler against the 100 mm scale at the top to confirm.
Paper strip
Cut along the dashed strip on the left. Wrap it around the finger snugly but not tight. Mark where the free end meets the start, then read the US size at the mark.
Overlay circles
Place a ring that already fits over each circle on the right. The circle whose inner edge lines up with the inside of the ring is the size.
Fingers swell during the day, in heat, and after meals. Measure twice at different times. Pick the larger reading for everyday rings, the snugger reading for eternity bands.
