How to Find Your Ring Size: A Complete Guide

Buying a ring online or as a gift can be tricky if you are unsure about the size. A properly fitting ring should be comfortable, secure, and flattering. In this guide, we will explain how to measure your ring size, what size a US 7 is in Australia, and tips for ensuring the perfect fit.

How Do I Know My Ring Size?

There are two simple ways to measure your ring size.

Method 1: Measure Your Finger

1. Cut a strip of paper or string about 10 cm long.
   

2. Wrap it around the base of your finger where the ring will sit, ensuring it is snug but not tight.
   

3. Mark the point where the paper or string overlaps.
   

4. Measure the length from the mark to the end of the strip in millimeters. This is your finger circumference.
   

5. Use an online ring size chart to convert your measurement to the corresponding ring size, including US, UK/Australia, and other sizing systems.
   
   

Method 2: Measure an Existing Ring

1. Find a ring that fits the intended finger comfortably.
   

2. Measure the internal diameter of the ring using a ruler in millimeters.
   

3. Match the measurement to a ring size chart that shows US and Australian sizes.
   
   

Tips for Best Results

• Measure at the end of the day when your fingers are largest.
  

• Consider the width of the band. Wider bands may require a slightly larger size.
  

• Repeat the measurement process a few times for accuracy.

Can I Measure My Ring Size on My Phone?

Yes. There are apps like The Ring Sizing App™ that allow you to measure your finger directly on your phone screen. Simply place your finger on the screen and adjust the sizing lines to outline it. The app will provide your ring size, including Australian sizing, within minutes.

Is It Better for a Ring to Be Tight or Loose?

A ring should fit snugly enough to stay in place but loose enough to remove comfortably. Fingers can swell due to temperature, activity, or diet, so finding a balance is key.

Signs of a Proper Fit

• Slides on easily without force
  

• Snug at the base for security
  

• Slight resistance when removing, like twisting gently
  

• Leaves no deep indentations
  

• Does not spin excessively
  
  

Signs a Ring Is Too Tight

• Skin bulges above or below the ring
  

• Pain, tingling, or discomfort
  

• Deep indent marks
  
  

Signs a Ring Is Too Loose

• Slides freely up and down the finger
  

• Spins easily
  

• Feels insecure and may fall off during activity
  
  

Additional Tips

• Measure when your fingers are stable, often in the mid-afternoon
  

• Wider bands feel tighter than narrower bands of the same size
  

• For the most accurate fit, have a professional jeweler measure your finger
  
  

Final Thoughts

Finding the right ring size ensures comfort, security, and confidence when wearing a ring. Including Australian sizes in your measurements makes it easier to shop locally or online in Australia. Whether you measure your finger with a string, use an existing ring, or try a phone app, accuracy is important. With the right approach, you can find a ring that fits perfectly every time.
