Ring sizing tips

Finding Out Someone Else’s Ring Size

Want to surprise a loved one with a beautiful ring? The first step to finding their perfect piece of jewelry is figuring out their ring size. There are a few ways you can do this without raising any suspicion.

Check their jewelry

One of the easiest ways to find out someone else’s ring size is to check their other jewelry. Take a peek inside their jewelry box and analyze the rings they already have. Use a ruler to measure the diameter of a couple of the rings. That way, you’ll have enough information to closely guess your loved one’s ring size.

Use a piece of string

While it may be tricky, using a piece of string is a great way to measure ring size if you’re buying for a partner.

Wrap a small piece of string around your partner’s finger while they’re sleeping and use a pen to mark where the ends meet. Take the string to a jeweler and you’ll receive an accurate measurement of ring size.

Ask friends or family

Encourage your loved one to try on their friends’ or family members’ rings so you can get a better idea of what their ring size might be.

HOW TO MEASURE YOUR DIAMETER

Diameter is the measurement across the inner width of the ring

You’ll need:

  • A ring that fits you
  • Ruler
Step 1:

Find a ring that fits.

Step 2:

Lay ring on top of ruler, and measure the widest area inside the ring from inner edge to inner edge. Round to the closest whole millimetre.

Tip:

If your ring is a different shape and is not circular, measure the shortest distance across.

HOW TO MEASURE YOUR CIRCUMFERENCE

Circumference is the measurement around the base of the finger

You’ll need:

  • 5mm wide strip of paper
  • Pencil of fine tip pen
  • Ruler
Step 1:

Cut a long strip of paper that is 5mm wide.

Step  2:

Wrap a strip of paper around the base of desired finger. For the most accurate result, pull paper as tight as possible.

*Don’t worry! The correct ring size is determined based on a tight measurement. The ring itself won’t fit that tight.

Step  3:

Make sure the paper is evenly overlapped and pulled tight, and mark where the strip of paper meets itself.

Step  4:

Measure the length of the strip of paper in millimetres. Round to the closest whole millimeter.
