How to Measure Ring Size at Home

The three easiest ways to measure your ring size without our free sizer are:   
  • The string method   
  • Using a printable ring sizer   
  • Measuring an existing ring to determine a size that already fits   
These methods require our Ring Sizer & Conversion Chart. To print the chart for methods two or three, set page scaling to "100" in your print settings and use 8.5 x 11-inch standard paper.

Method One: Create Your Own Ring Sizer

 
What you'll need:   
  • Printer & paper    
  • String, yarn, floss, or a thin strip of paper    
  • Pen or marker    
  • Ruler  
Steps:   
  1. Cut a piece of string, yarn, floss, or thin strip of paper to at least three inches long.   
  2. Wrap one end of the string around the base of the intended finger.
  3. Using a pen or marker, mark where the end of the string overlaps with the rest.
  4. Lay the string flat and use a ruler to measure the length between the end and your mark in millimeters.
  5. Use the Ring Size Conversion Chart to match the millimeter length to the corresponding ring size.

Method Two: Print a Ring Sizer

 

 

What you'll need:   
  • Printer & paper   
  • Scissors   
Steps:
  1. Print the Printable Ring Sizer & Conversion Chart. Set page scaling to "100" in your print settings and use 8.5 x 11-inch standard paper.
  2. Cut out the ring sizer and the slot as instructed. 
  3. Wrap the paper ring sizer snuggly around the base of the intended finger so that the numbers are visible and insert the pointed end through the slit you made in the sizer.
  4. Note the number that lines up with the slit; this is your ring size! Remember that quarter sizes are also available if your sizer indicates that you are between whole and half sizes. 

Method Three: Measure an Existing Ring with Our Chart

What you'll need:   
  • Printer & paper   
  • Scissors   
  • An existing ring 
  
Steps:
  1. Print the Printable Ring Sizer & Conversion Chart. Set page scaling to "100" in your print settings and use 8.5 x 11-inch standard paper.
  2. Choose a ring that correctly fits the intended finger.
  3. Lay the ring over each size circle within the chart until you can closely match the inside edge to one of the circles on the guide. If the ring falls between two sizes, contact us to order the quarter size between them.

Brilliance in Every Purchase: Customer Experiences

Choosing Walter Steiner to create my fiancee’s dream ring was the right decision. We were planning this purchase for a long time and she had a lot of requirements. Their customer service can’t be beat and the entire experience from design through delivery was top quality. 

- Shelby and Janice Groetz

My husband surprised me with some money to buy myself a diamond piece and Walter Steiner worked with me to create a beautiful solitaire heart diamond necklace that fit within my budget. It is a real show stopper and I can’t wait to design my next diamond piece with them. 

- Lia Marway

I wanted a princess cut diamond ring but I wanted something different, something no one else had. Walter Steiner showed me a few diamonds to choose from and then we created the setting design. I get asked every day where my ring is from and I always send them to Walter Steiner.

I inherited my grandmother’s ring to give to my future wife but was outdated for my girlfriend. I brought it to Walter Steiner and they helped me design the perfect ring setting to fit the diamond and it didn’t even come close to the price I thought it would be. I saved money and stress by choosing them. I know she’ll say yes.

- Mark Dingsley

I shopped for diamond studs for a long time but I couldn’t find the perfect set. I wanted perfection but I also had a tight budget. Walter Steiner gave me my dream piece and I am already working on my next diamond piece with them. Definitely the only place I will shop from now on.
