Understanding the Finger to Palm Ratio

Everyone's hands are slightly different. Some people have longer fingers, others have broader palms, and most never stop to think about the proportions at all. The finger to palm ratio is simply a way to compare these two measurements in a clear and measurable way.

This calculator does not judge or label your result. It only helps you understand the numeric relationship between finger length and palm length.

How to Measure Correctly

Finger Length

  • Use your middle finger for consistency
  • Measure from the base (where finger meets palm) to the tip
  • Keep finger straight and relaxed

Palm Length

  • Measure from the base of your palm to the crease below your fingers
  • Do not include the fingers in this measurement
  • Keep hand flat and relaxed

Formula Explained in Simple Terms

The formula is straightforward:

Finger to Palm Ratio = Finger Length รท Palm Length

This means you divide the length of your finger by the length of your palm. The result is a number that shows how long the finger is compared to the palm.
