<p style='text-align:justify;'>Pramanatah means measurement or proportion and pariksha means examination. The term pramanatah pariksha indicates examination by measurements or proportion. These are means to quantitatively express the proportions of the human body  parts.  In ancient era, the measurements were done by angula (fingers) and anjali (the cup shaped hallow formed by the joining of two palms together). These measurements are referred as anguli pramana and anjali pramana respectively. These measurements are individual specific. Though evolution of technology led to invention of accurate and precise measuring devices, still the ancient means of measurements via anguli and anjali maintain their clinical importance, being an easy, inexpensive, and scientifically justifiable mode of measurement. The anjali pramana is used for measuring the volume of fluid constituents, whereas anguli pramana is used for measuring the dimensions (length, breadth, height, circumference, distance between two points, etc). Pramana pariksha is one of the ten-fold clinical examinations of patient. [Cha.Sa.Vimana Sthana 8/94] Having well developed and proportionate body parts is one sign of good health. [Su.Sa.Sutra Sthana 15/40] Underdeveloped or overdeveloped body parts can lead to disease. The present chapter deals with concept and practices of pramana pariksha. The contemporary science also gives importance to anthropometric measurements and evaluation of body composition. It is assessed on the basis of the nutritional status of an individual. This chapter describes pramanatah pariksha, its application and importance in healthcare practices. <p style="text-align:justify;">{{Infobox

Ø  Certain differences are observed in the measurements of a human body via anguli pramana. The measurements described by the two Ayurveda scholars are the approximations of body parts of an ideal person. But criteria of idealness vary from person to person. For a person who is native of plains, a long height may be an ideal height. While for a person who is native of hilly areas, shorter height may be the ideal height. This difference in opinion may be the reason of variation in anguli pramana of Charak and Sushrut.

The equilibrium of dosha, dhatu (body tissues) and mala (metabolic waste of body) is responsible for keeping a person healthy. Any derangement in pramana leads to disorders. Example depletion of rasa dhatu (plasma) causes precordial pain, palpitation, sense of emptiness and thirst, whereas increase in pramana of rasa dhatu may result in nausea and salivation.

It’s difficult to understand how the ancient Ayurveda scholars estimated the volume of body fluids. Ayurveda scholars had an understanding of qualities of substances based on their panchabhautika composition (the five universal elements or panchamahabhuta). The proportion or volume of a substance in most cases has a direct relationship with its qualities. For example, proportion of water present in a substance decides moisture content or dryness in it. In the absence of advanced medical techniques, how the volume of body fluids was measured in ancient times is a topic for research. Most probably the Ayurveda scholars estimated the qualities of fluid in body and thereafter assessed its volume inside the body.

===In determining life span===

Any deviation from the normal measurements possibly points towards an anatomical or genetical anomaly, which may consequently reduce the life span of the person. According to Ayurveda scholars, a person with tip of the nose raised lives a maximum life span of 70 years [Su. Sa. [[Sutra Sthana]] 35/8]; and a person whose phalanges are short, penis enormously bigger positioned upwards from its normal place, nose higher and gums visible while laughing or talking lives a maximum life span of 25 years only. [Su. Sa.  [[Sutra Sthana|Sthana]] 35/9-11] Contrarily, if a man or woman, endowed with standard body and body organ measurements, then he attains long life and prosperity [Su. Sa. [[Sutra Sthana]] 35/16-17]. It is also postulated that if the height of person in standing position is equal to the arm span of that person, than this person is said to possess sama sharira (body with optimum proportion of measurements of body parts). A sama sharira person is endowed with longevity, strength, ojas (the essence of all seven dhatus or tissues, that is vital for life), happiness, power, wealth, and virtues. [Cha. Sa. [[Sutra Sthana|Viman Sthana]] 8/117]

*Pramanataha pariksha is helpful in identification of four (too tall, too dwarf, too fat or too emaciated) among eight of the undesirable constituents. [Cha. Sa. [[Sutra Sthana]] 21/3] A person aspiring good health shall make possible efforts to reach close to the standards measurements. For example, reducing weight for an obese person is possible by suitable diet and exercise. However, increasing height of a dwarf adult or decreasing height in tall person is not possible by medical management.

Pramantaha pariksha is like anthropometry (the '''systematic measurement of th'''e physical properties of the human body, primarily dimensional descriptors of body size and shape). Anthropometry, along with physical measurement of human body, also takes into consideration the body weight, body parts, human physical appearance and physical attractiveness.
