Largest Bone in Human Body, List of Top-10 Largest Bones

The human body is a marvel of biological engineering, composed of various intricate systems working in unison to support life. At the core of this remarkable structure lies the skeletal system, providing stability, protection, and mobility. Among the myriad bones that make up this framework, some stand out for their size and importance. In this article, we delve into the top 10 largest bones in the human body, shedding light on their functions and significance.

Largest Bone in Human Body

The femur, or thighbone, is the longest, strongest, and heaviest bone in the human body. It extends from the hip to the knee, supporting the body’s weight and providing stability for movements like walking and running. Resistant to immense forces, it can withstand up to 1,800-2,500 lbs of pressure. Serving as an anchor for ligaments and muscles, the femur also houses bone marrow stem cells crucial for producing red blood cells, vital for oxygen transportation.

Top-10 Largest Bones in Human Body

Femur (thighbone), with the average length of 19.9 inches, holds the distinction of being the largest bone in human body, followed by Tibia (shinbone), Fibula (lower leg), and Humerus (upper arm).

Here is list the top-10 largest bones in human body:

Longest Bones in Human Body
Rank	Bone	Average Inches
1.	Femur (thighbone)	19.9
2.	Tibia (shinbone)	16.9
3.	Fibula (lower leg)	15.9
4.	Humerus (upper arm)	14.4
5.	Ulna (inner lower arm)	11.1
6.	Radius (outer lower arm)	10.4
7.	7th rib	9.5
8.	8th rib	9.1
9.	Innominate Bone (hipbone)	7.3
10.	Sternum (breastbone)	6.7

Largest Bone in Human Body – Femur (thighbone)

Average Inches: 19.9

The femur, the longest bone in the human body at an average length of 19.9 inches, supports weight and stabilizes gait from hip to knee. Resilient to immense forces, it withstands up to 1,800-2,500 lbs, making it the strongest and heaviest bone. Serving as an anchor for ligaments and muscles, it aids in maintaining posture and facilitating movements like walking and running. Additionally, it houses bone marrow crucial for red blood cell production, essential for oxygen transport.

Second Longest Bone in Human Body – Tibia (shinbone)

Average Inches: 16.9

The tibia, or shinbone, measuring approximately 16.9 inches, ranks as the second-largest bone in the human body. It acts as a crucial connector between the knee and ankle, supporting movements like running, walking, and jumping. Also known as the shankbone, it plays a vital role in facilitating quick turns and providing stability to the lower leg. The tibia supports both the femur and ankle, contributing significantly to everyday mobility.

Third Largest Bone in Human Body – Fibula (lower leg)

Average Inches: 15.9

The fibula, measuring around 15.9 inches, stands as the third-largest bone in the human body, located in the lower leg. Unlike the weight-bearing tibia, its primary role is to support and stabilize the ankle joint, working in conjunction with ligaments attached to its grooves. Injuries often involve the fibula, particularly in ankle-related incidents. Interestingly, its name “fibula” derives from Latin, meaning “brooch,” resembling an old-fashioned pin akin to those worn during special occasions, evoking a unique visual analogy.
