Average Index vs. Ring Finger Length

Can the length of your fingers tell you about your personality, future, love life, and career prospects? Many people think so, and although this hasn't been definitively proven, there have been some scientific studies that link finger length to personality traits. In this article, we’ll break down the popular personality traits commonly associated with different finger lengths before diving into what the scientific community has to say about differences in your digits. The answers will surprise you, so read on!

Finger Ratio and Length Meanings

Science is actually split on whether finger length impacts personality. Believe it or not, this has been studied quite a bit! Some studies claim that certain physical and personality traits can be linked to the same hormones that impact the development of finger length.^{[8]

Research source} With that said, many of these insights haven’t been replicated in other studies, and correlation doesn’t necessarily indicate causation, so there’s no definitive answer here.^{[9]

- The studies that look at finger length and personality traits focus primarily on neonatal hormones that people are exposed to in development. It is thought that finger length is a byproduct of androgen (male growth hormones) exposure—especially testosterone, which may be why men tend to have slightly longer fingers relative to their size.^{[10]

Genetics and natal hormones determine finger length. Your finger length is a lot like your cheekbones and height—you’re just getting what your parents gave you. Your genes determine the length of your fingers in development, but it also looks like androgens (male growth hormones) that a mother is exposed to while pregnant can have an impact on the length of a child’s fingers.^{[11]

Average Index Finger Length vs. Ring Finger Length

It's most common for a ring finger to be longer than an index finger. The most common finger length measurement is the 2D-4D ratio. The 2D-4D ratio refers to the difference between your index finger (2D, or the second digit) and your ring finger (4D). On average, most people have a slightly longer ring finger than index finger. This difference is more pronounced in men.^{[13]

- What is the average 2D-4D ratio? In men, the average ratio is 0.95 (meaning the index finger is 0.05% shorter than the ring finger), while the average ratio for women is 0.97.^{[14]

- Men tend to have slightly longer fingers than women overall. Even when you adjust for the height differences in men and women, men tend to have longer fingers with slightly less difference between the ring and index fingers.
