Sri Hanuman describes the characteristics of Sri Rama

Seetha asked him to narrate as to how did he came into contact with Sri Rama Lakshmana and how did the union between Vanara-s and men arise.  She further asked him to describe the characteristics and the appearance of Sri Rama and Lakshmana. 

Sri Hanuma then started to describe Sri Rama as follows:

"O Seetha! Sri Rama has his eyes resembling the petals of a lotus. He has handsomeness, attracting the hearts of all living beings. He is endowed with grace and dexterity, by birth."

तेजसा आदित्य सम्काशः क्षमया पृथिवी समः |
बृहस्पति समो बुद्ध्या यशसा वासव उपमः ||

रक्षिता जीव लोकस्य स्व जनस्य च रक्षिता |
रक्षिता स्वस्य वृत्तस्य धर्मस्य च परम् तपः ||

रामो भामिनि लोकस्य चातुर्वर्ण्यस्य रक्षिता |
मर्यादानाम् च लोकस्य कर्ता कारयिता च सः ||

(Sundara Kanda 35 Sarga 9 - 11 Slokas)

"He is equal to the sun in splendour, earth in endurance, Brihaspati in intelligence and Indra in fame. Sri Rama the tormentator of his adversaries, is a protector of the world of beings, further protecting his own people. He is the protector of his own behaviour and righteousness. O Seetha! Sri Rama is the protector of the four Varnas of the world. "

त्रिवलीवांस्त्र्यवनतश्चतुर्व्यङ्गस्त्रिशीर्षवान् |
चतुष्कलश्चतुर्लेखश्चतुष्किष्कुश्चतुःसमः ||(Sundara Kanda 35 Sarga 18 Sloka)

"He has four lines at the root of his thumb (denoting his proficiency in the four Vedas). He has four lines on his forehead (indicating longevity). He is 4 cubits high (96 inches). He has four pairs of limbs (viz. the cheeks, arms, shanks and knees) equally matched."

"The invincible Lakshmana, is resembling Sri Rama in appearance, affection and in qualities. Sri Rama and Lakshmana, the two tigers among men, very anxiously desirous of seeing you and searching all over the earth, came in contact with us."

Sage Valmiki described through Sri Hanuma that Sri Rama’s height was 4 cubits (armlength) – chetushkishku.  Many scholars taken the length of a Cubit (armlength) as 24 inches and calculated the height of Sri Rama as 96 inches or 8 feet.  

We do not know the exact age of Srimad Ramayana and the actual length of a Cubit (an armlength), people used to adopt in that age. 

If the average height of human beings in a particular country or area 6 feet then the length of arm they adopt will be different and if the average height of humans is 10 feet then different result will be obtained.
