How to Measure Ring Size at Home?

With a few tools and steps, you can measure ring size accurately right from your home.

Tools To Measure Ring Size at Home:

To measure ring size at home you can use:

A strip of paper or non stretchy string
A ruler (preferably with millimeters)
A pen or marker
A ring size chart (you can find printable versions online)

Measure Ring Size Using a String or Paper Strip

1. Cut a thin strip of paper or use a string.
   Make sure it is about 6 inches long and not stretchy.
   
2. Wrap it around the base of your finger.
   This is where the ring will sit. Make sure it is snug but not too tight.
   
3. Mark the point where the string or paper overlaps.
   Use a pen or marker to make a clear line.
   
4. Measure the length from the end to the mark.
   Use a ruler to measure in millimeters (mm).
   
5. Compare your measurement to a ring size chart.
   Each size corresponds to a specific circumference. For example:
   
   • 50 mm = Size 5
     
   • 54 mm = Size 7
     
   • 57 mm = Size 8
     

 Measure Ring Size Using an Existing Ring

If you already have a ring that fits the intended finger perfectly you can use it to find the size.

1. Place the ring on a ruler.
   Measure the diameter (inside edge to inside edge) in millimeters.
   
2. Use a ring size conversion chart.
   Match the diameter to a size. For example:
   
   • 16.5 mm = Size 6
     
   • 17.3 mm = Size 7
     
   • 18.1 mm = Size 8
     

Tips for Accurate Measurement of Ring Size

• Measure your finger at the end of the day. Fingers can swell throughout the day so it is better to measure when they are at their best.
  
• Do not measure cold fingers. Cold weather can shrink your fingers slightly which can lead to an inaccurate measurement.
  
• Consider the knuckle. If your knuckle is much larger than the base of your finger then measure both and choose a size in between.
  
• Use non-stretchable material. Stretchy strings can give false results.
