Print out our easy Ring Sizing Guide if you want to measure your ring size immediately. Check that page scaling is set to "none" in your print dialog box before printing the guide. At home, use the Ring Sizing Guide to measure a ring by placing it over the sizing dots until it matches the inner edge of your ring. Then double-check that you're buying a ring for the correct finger (and hand).

Start by cutting out the ring sizer. Next, wrap the ring sizer snugly around the most comprehensive portion of the intended finger, with the numbers exposed, and push the pointed end through the hole you made. Finally, identify which number aligns with the cut; this is your wedding band size!

1. Don't forget to measure the correct finger on your right hand - our dominant hands are generally a bit larger.

2. Rings with wider bands will fit a bit more snugly. If you're trying to measure one of your partner's rings, choose one with a similar width as the ring you're interested in purchasing.

3. Ensure the finger is at room temperature (i.e., neither hot nor cold).

4. You might not realize it, but your fingers swell and shrink throughout the day. So wait until the end of the day to get an accurate finger measurement.

5. If your knuckle is larger, take two measurements. First, the ring needs to fit over the knuckle but not be too loose; otherwise, it will shift around.

6. Are you planning a proposal? Great! But before you pop the question, make sure you know her ring size. Check out our guide on How to Measure Ring Size for a Surprise Proposal.

7. If you're unsure of your partner's ring size, choosing one of the standard sizes is your best bet. The average ring size for women falls between 6 and 6.5, while the average for men lies between 9 and 10.
