Traditionally, arm span is measured between the middle finger of one hand to middle finger of your other hand. Have your partner take a measuring tape and measure from the tip of your middle finger on your left hand to the middle finger on your right hand.

How do you find the proportion between height and wingspan?

The proportion of wingspan to height is found by dividing the wingspan of the person over their measured height. Graphically the proportion of height to wingspan is represented by coefficient A on the proportional fit equation, y=A*x, shown on the Wingspan vs Height graph. The proportion was found to be 1.023.

How is the golden ratio of arms calculated?

Find the ratio of the two measurements in the following way: Ratio = (full length of arm) / (length of lower arm) = a/b • Compare your ratio with the Golden Ratio.

How do you calculate upper and lower segments?

Upper to lower segment ratio (U/L) reflects trunk vs legs ratio, where lower segment is the distance from the middle of pubic symphysis to the floor level and upper segment is height minus lower segment. At birth, U/L is about 1.7:1 or trunk longer than legs.

Why is arm span measured?

Arm span is an important measure for the assessment of growth and hormone deficiency diseases. In an epidemiological survey, with a large number of subjects’ indicators, it is especially valuable to establish methods which can measure both quickly and accurately.

What is the ratio of wingspan fingertip to fingertip?

one-to-one ratio
An example of a human body ratio is a person’s arm span—the distance from the left hand’s middle fingertip to the right hand’s middle fingertip when stretching out both arms horizontally—to their height. This ratio is approximately a one-to-one ratio, meaning that a person’s arm span is about equal to their height.

What is the ratio of wingspan?

one to one ratio
An example of a human body ratio is a person’s arm span—the distance from the middle fingertip of the left hand to that of the right hand when stretching out both arms horizontally—to their height. This ratio is approximately a one to one ratio, meaning that a person’s arm span is about equal to their height.

How do you calculate golden ratio?

The Golden Ration Defined Algebraically, if you have two numbers, A and B, it has to be such that (A + B) divided by A = A divided by B. In most cases, this is going to be a comparison result in a ratio of 1:1.618. This appears naturally all over your body.
