Human arm
The human arm is the upper limb of the body, extending from the shoulder to the hand and enabling a wide range of movement and manipulation.

Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. A ruler represents the selected distance or a measurement not visible in this view.
A little perspective
75 centimetres is approximately equal to the shoulder-to-fingertip length of the human arm.

75 centimetres
Length: 75 cm; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Human arm
Defined shoulder-to-fingertip length: 75 cm; representative model; range 65 cm–85 cm.
One complete arm in a defined 70 kg adult model: 75 cm from shoulder to fingertip and 3.46 kg, using published upper-arm, forearm and hand mass fractions. This is a comparison model, not a population average.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 75 cm for the shoulder-to-fingertip length of the human arm; the recorded range is 65 cm–85 cm.
- The shoulder-to-fingertip length of the human arm: This is a representative comparison value; individual specimens or conditions can vary.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
This comparison follows the selected length only; other dimensions may differ.
