NDA Physical & Medical Standards: Complete Guide

Clearing the NDA (National Defence Academy) written exam and SSB interview is only part of the journey. Candidates must also meet the stringent physical and medical standards set by the Union Public Service Commission (UPSC) and the Armed Forces Medical Services. This comprehensive guide details the height, weight, vision, and general medical requirements for the Army, Navy, and Air Force.

1. General Physical Standards

The Armed Forces require candidates to be in excellent physical and mental health, free from any disease, syndrome, or disability that might interfere with the efficient performance of military duties in any terrain or climate. A candidate must be physically fit according to the prescribed physical standards.

Before we dive into the specific measurements, here are some general physical requirements:

• The candidate should be free from any past history of mental breakdown or fits.
• Hearing should be normal. The candidate should be able to hear a forced whisper with each ear at a distance of 610 cm in a quiet room.
• There should be no evidence of present or past disease of the ear, nose, and throat.
• Blood pressure should be within normal limits.
• There should be no enlargement of the liver or spleen. Any evidence of disease of internal organs of the abdomen will be a cause for rejection.
• Un-operated hernias will make a candidate unfit.
• Skin should be healthy and free from any chronic diseases.

2. Height and Weight Standards

Height and weight standards vary slightly depending on the branch of the Armed Forces you are applying for and your age at the time of entry. It is crucial to maintain a weight proportionate to your height.

Army and Navy Height Standards

For the Army and Navy, the minimum acceptable height is 157 cm. However, for candidates belonging to certain regions, there are relaxations:

• Gorkhas and candidates belonging to the hills of North-Eastern regions of India, Garhwal, and Kumaon: 152 cm.
• Candidates from Lakshadweep: 155 cm.
• Candidates from Andaman & Nicobar Islands: 155 cm.

Air Force Height Standards

The Air Force has stricter height requirements, especially for the Flying Branch.

• The minimum acceptable height for the Air Force (Flying Branch) is 162.5 cm.
• Leg Length: Minimum 99 cm, Maximum 120 cm.
• Thigh Length: Maximum 64 cm.
• Sitting Height: Minimum 81.5 cm, Maximum 96 cm.

For Ground Duty branches in the Air Force, the minimum height requirement is generally 157.5 cm.

Weight Correlates

Weight should be strictly correlated to height and age. A variation of up to ±10% from the ideal weight is generally acceptable. Overweight or obese candidates are unfit for service. Here is a general reference for a 16-17 year old candidate:

3. Vision Standards

Vision is a critical component of the medical examination. The standards vary significantly between the Army, Navy, and Air Force.

Army Vision Standards

• Uncorrected vision: 6/36 in both eyes.
• Corrected vision: 6/6 in the better eye and 6/9 in the worse eye.
• Myopia (Short-sightedness): Should not exceed -2.5 D (including astigmatism).
• Hypermetropia (Long-sightedness): Should not exceed +3.5 D (including astigmatism).
• Color Vision: CP-III (Defective safe).

Navy Vision Standards

• Uncorrected without glasses: 6/12 in the better eye, 6/12 in the worse eye.
• Corrected with glasses: 6/6 in the better eye, 6/6 in the worse eye.
• Limits of Myopia: -1.5 D.
• Limits of Hypermetropia: +1.5 D.
• Color Vision: CP-I (Normal).

Air Force Vision Standards (Flying Branch)

• Uncorrected vision: 6/6 in one eye and 6/9 in the other, correctable to 6/6.
• Limits of Myopia: NIL (No myopia is allowed).
• Limits of Hypermetropia: +2.0 D (including astigmatism).
• Astigmatism: +0.75 D Cylindrical.
• Color Vision: CP-I (Normal). Color blindness is a strict ground for rejection.
• Candidates who have undergone PRK/LASIK laser surgery are generally not accepted for the flying branch.

4. Tattoo Policies

The Armed Forces have strict regulations regarding permanent body tattoos:

• Allowed Locations: Permanent body tattoos are only permitted on the inner face of the forearm (from the inside of the elbow to the wrist) and on the reverse side of the palm/back (dorsal) side of the hand.
• Tribal Tattoos: Permanent body tattoos on any other part of the body are unacceptable. However, candidates belonging to tribal communities (as declared by the Government of India) may be permitted to have tattoos on other body parts, subject to specific regulations and verification.
• Offensive Tattoos: Tattoos that are lewd, racist, sexist, or offensive are strictly prohibited and will lead to immediate rejection, regardless of location.

5. Common Causes of Rejection

Many candidates are unaware of minor physical conditions that can lead to permanent or temporary rejection during the medical boards. It is highly recommended to get a preliminary medical check-up done before the SSB interview to identify and, if possible, rectify these issues.

The most common causes for medical rejection include:

• Knock Knees (Genu Valgum): When standing with knees touching, the distance between the medial malleoli (inner ankles) should not exceed 5 cm.
• Flat Foot (Pes Planus): The arches of the feet must be well-formed. Completely flat feet are a cause for rejection.
• Bow Legs (Genu Varum): Outward bowing of the legs.
• Sweaty Palms and Soles (Hyperhidrosis): Excessive sweating of palms and soles.
• Carrying Angle of the Elbow: For males, the carrying angle should generally not exceed 15 degrees.
• Pigeon Chest: Deformity of the chest wall.
• Defective Vision: Failing to meet the specific myopia, hypermetropia, or color vision standards.
• Dental Issues: Candidates must have a sufficient number of natural teeth in good condition (a minimum of 14 dental points). Severe pyorrhea or missing teeth can cause rejection.
• Deviated Nasal Septum (DNS): Significant deviation causing obstruction may require surgery prior to joining.
• Overweight/Underweight: Failing to meet the height-weight correlation charts.
• Phimosis: Inability to retract the foreskin.
• Ear Wax: A common temporary rejection. Candidates should get their ears cleaned by a professional before the medical exam.

Conclusion

The physical and medical standards for the NDA are uncompromising. They are designed to ensure that every officer cadet can withstand the rigorous training and subsequent operational deployments without endangering themselves or their comrades. If you are aspiring to join the NDA, start focusing on your physical fitness early, eat a balanced diet, and consult a medical professional if you suspect any minor issues like ear wax or flat feet. Discipline in physical health is the first step toward a disciplined life in the Armed Forces.
