The middle finger is generally considered the most powerful finger.
Understanding Finger Strength
Several studies and analyses point to the middle finger's superior strength contribution to overall grip strength. This is due to its anatomical position and the way muscles are connected. The middle finger is often the longest and most robust, providing more strength and stability compared to the other fingers.

Grip Strength Studies: Research consistently shows that the middle finger is the most significant contributor to overall hand grip strength. For example, one study concluded that "The middle finger was the most important contributor to grip strength." https://pubmed.ncbi.nlm.nih.gov/25085045/

Ulnar vs. Radial Contribution: While the middle finger leads in individual strength, it's important to note that the ulnar side (pinky and ring fingers) contributes approximately 40% to overall grip strength. The radial side (thumb and index finger) accounts for roughly 60%. https://www.researchgate.net/publication/8435430_Individual_finger_strength_Are_the_ulnar_digits_powerful
-
Second Strongest Finger: The ring finger frequently ranks as the second strongest, often closely following the middle finger in strength. https://www.mountainproject.com/forum/topic/107855960/which-finger-is-second-strongest Individual variations can exist, however.

Individual Variations: It's crucial to remember that individual finger strength can vary based on factors like genetics, hand size, and regular use. Personal experiences reported online illustrate this, showing diverse strengths across different fingers. https://www.ukclimbing.com/forums/walls+training/which_finger_is_seond-strongest-524573
