How Long is a Human Arm?

The average human arm length is approximately 25 inches from the shoulder to the tip of the middle finger. This measurement can vary slightly depending on an individual’s height, weight, and body type.

Factors That Affect Arm Length

Height is one of the most significant factors that affects arm length. Generally, taller people have longer arms than shorter people. Additionally, body type can also influence arm length. People with a more muscular build tend to have longer arms than those with a slimmer physique.

Weight can also play a role in arm length. People who are overweight may have shorter arms due to excess fat tissue in the upper body. Conversely, people who are underweight may have longer arms due to their lack of muscle mass.
