Finding Your Ring Size

the perfect tungsten rings

Tungsten Direct realizes that you may not know the ring size for a given finger, and we want to help. We provide a printable ring sizer that can help you determine your ring size.

Tungsten Ring ResizerComplimentary Ring Sizer

NOTE: In the Print dialog box, make sure that you do not have "Shrink oversized pages to fit paper size" or "Expand small pages to paper size" selected, and that Page Scaling is set to None. Use Method A or B on the Ring Size Finder printout to determine your own or someone else's ring size.

Tips for Measuring Your Finger

Here are some tips to make your ring size measurement more accurate:

  • Confirm the printed paper size with a ruler.
  • Pull tightly. The sizer must fit snugly to produce an accurate size.
  • Don't measure cold fingers. This is when fingers are their smallest.
  • For the most accurate reading, measure your finger at the end of the day when it is largest.

Tips for Buying a Ring for A Surprise

- Ask your partner's mother or one of her friends if they know her finger size.
- Borrow one of your partner's rings (from the correct finger) and use the Ring Sizer PDF to determine its size.

What if it's the Wrong Size?

Don't worry if you've ordered the wrong size. Just ship the ring back to us, and we'll re-size it any time. See our policies for details.

*Tungsten rings tend to run a half size larger then other metals. This is partly due to the comfort fit of our rings.
