Clearing the UPSC NDA written examination and earning a recommendation from the Service Selection Board (SSB) are tremendous milestones. However, the final hurdle before your name appears in the official Ministry of Defence merit list is the NDA medical examination conducted by the Special Medical Board (SMB). Every year, nearly 20% to 25% of recommended candidates face temporary or permanent rejection simply due to preventable physical or medical shortcomings. In this authoritative guide, Path Finder Defence Academy details the exact height, weight, eyesight, and physical conditioning standards required to secure a clean medical clearance.
How the NDA Special Medical Board (SMB) Operates
Immediately after your SSB interview recommendation on Day 5, candidates are moved to the nearest designated Military Hospital or Command Hospital for a rigorous 4-to-5-day comprehensive medical screening. You will be evaluated by military specialists across major disciplines:
- Surgery: Assessment of limbs, spinal curvature, hernia, hydrocele, carrying angle, and varicose veins.
- General Medicine: Blood pressure, heart rate, ECG, chest X-rays, blood profiles, and ultrasound screening.
- Ophthalmology (Eye): Distant vision, near vision, color perception, squint, pupil dilation, and fundus examination.
- ENT (Ear, Nose, Throat): Audiometry hearing test, eardrum perforation checks, Deviated Nasal Septum (DNS), and tonsils.
- Dental Examination: Calculation of dental points (minimum 14 points required out of 22 for healthy natural teeth).
Physical Fitness Benchmarks: What You Must Achieve
Cadets at the National Defence Academy, Khadakwasla endure rigorous physical regimes involving endurance runs, cross-country marches, obstacle courses, and swimming. To ensure you can cope with academy life without injury, start training 6 to 12 months before your exam date to meet these benchmarks:
- Running: 2.4 km running in 15 minutes (ideally under 12 minutes for competitive fitness).
- Push-ups: Minimum 20 to 30 clean repetitions with proper form and tempo.
- Sit-ups (Crunches): Minimum 25 to 30 repetitions within 60 seconds.
- Chin-ups / Pull-ups: Minimum 6 to 8 overhand chin-ups without swinging legs.
- Rope Climbing: Vertical rope climb up to 3 to 4 meters using arms and legs.
Minimum Height & Weight Standards
The Ministry of Defence specifies precise height-to-weight correlation charts based on age. Below are the primary baseline standards for NDA aspirants:
- Indian Army & Navy (Male): Minimum acceptable height is 157 cm. For candidates from the Gorkha community, Garhwal, Kumaon, and North-Eastern regions, a relaxation of 5 cm is granted (minimum 152 cm).
- Indian Army & Navy (Female): Minimum acceptable height is 152 cm (147 cm for Gorkhas and North-Eastern regions).
- Air Force Flying Branch: Strict minimum height requirement of 162.5 cm with specific leg length (99 cm to 120 cm), thigh length (maximum 64 cm), and sitting height (81.5 cm to 96 cm) to fit cockpit ejection seats.
Weight Clause: Weight must strictly fall within +/- 10% of the standard average for your corresponding height and age. Underweight or obesity is the #1 cause of temporary medical rejections.
Visual Acuity & Eyesight Standards
Visual standards depend heavily on whether you are applying for the Army, Navy, or Air Force Flying Branch:
- Indian Army: Uncorrected vision must be at least 6/36, correctable with spectacles to 6/6 in the better eye and 6/9 in the worse eye. Myopia limit is -2.50D and hypermetropia limit is +2.50D including astigmatism.
- Indian Navy: Uncorrected vision must be 6/12, correctable to 6/6 and 6/6. Myopia limit is -0.75D, hypermetropia +1.5D.
- Indian Air Force (Flying Branch): Requires strictly 6/6 uncorrected vision in both eyes. Spectacles are not allowed. Hypermetropia must not exceed +1.5D. Color vision must be CP-I (normal).
- LASIK Warning: Any laser corrective surgery (LASIK, PRK, SMILE) is permanently disqualifying for entry into the National Defence Academy.
Top 5 Preventable Medical Rejection Points
Many medical points given during SMB are easily preventable with proactive care:
- Knock Knees (Genu Valgum): When standing at attention with feet together, knees must not touch each other while ankles remain separated. Regular butterfly stretches and cycling help correct minor alignment.
- Flat Foot (Pes Planus): Lack of a natural plantar arch on the bottom of the foot can cause pain during marches. Walk barefoot on sand or use arch-support insoles.
- Carrying Angle (Cubitus Valgus): The natural angle of the elbow when palms face forward must be between 10 to 15 degrees for males and up to 18 degrees for females. An angle exceeding 20 degrees is cause for rejection.
- Wax in Ears: A surprisingly common reason for temporary rejection! Have an ENT specialist professionally clean your ears 10 days before your SSB reporting date.
- Permanent Tattoos: Tattoos are strictly banned on any body part except the inner face of the forearms or tribal communities with official cultural exemptions. Offensive, religious, or neck tattoos lead to instant disqualification.
