NDA Physical Requirements: Complete Guide to Height, Weight, Chest, Vision & Medical Standards
Aspiring to wear the uniform of the Indian Armed Forces starts with clearing the National Defence Academy (NDA) selection process. While the written exam and SSB interview test knowledge and personality, the final gatekeeper is the medical board. Understanding NDA Physical Requirements in detail helps candidates prepare early, avoid temporary or permanent rejection, and walk into the medical examination with confidence.
This comprehensive guide covers every major aspect of NDA physical and medical standards for both male and female candidates across Army, Navy, and Air Force wings. All standards mentioned here are based on the guidelines followed by the Armed Forces Medical Services and are subject to official updates in UPSC notifications.
Why NDA Physical Requirements Matter
The Indian Armed Forces demand officers who can endure rigorous training, operate in extreme climates, and lead troops under physical and mental stress. The medical examination ensures candidates are free from conditions that could limit performance or endanger safety. Meeting the NDA Physical Requirements is non-negotiable for final selection and joining the Academy at Khadakwasla.
Height Standards for NDA Candidates
Height is one of the first parameters checked.
For Male Candidates
- Minimum height for Army and Navy: 157 cm
- Minimum height for Air Force Flying Branch: 162.5 cm (some references list 163 cm)
- Ground Duty branches in Air Force: generally 157.5 cm
Relaxations for Male Candidates
- Gorkhas and candidates from North-Eastern hills, Garhwal, and Kumaon: 152 cm
- Certain island and tribal categories (Andaman & Nicobar, Lakshadweep, Ladakh): further limited relaxations as per official rules
For Female Candidates
- Minimum height for Army and Navy: 152 cm
- Air Force Flying Branch: 162.5–163 cm
- Ground Duty: 152 cm
Relaxations for Female Candidates
- Gorkhas and candidates from North-Eastern hills, Garhwal, and Kumaon: 148 cm (or 147 cm in some Air Force ground duty notes)
An allowance of about 2 cm for growth may be considered for candidates below 18 years at the time of examination in certain cases. Height is measured without shoes.
Weight Standards Linked to Height and Age
Weight must be proportionate to height and age. Charts published by the Armed Forces provide ideal weight ranges. A variation of up to ±10% from the ideal is generally acceptable. Underweight or overweight beyond this range usually leads to temporary rejection, giving the candidate time to correct the weight.
Separate height-weight charts exist for males and females, and they differ slightly across Army, Navy, and Air Force. Candidates are advised to check the latest official tables corresponding to their age group (typically 17–20 years for NDA entry). National-level athletes in bodybuilding, wrestling, or boxing may receive limited consideration for higher weight if BMI, waist-hip ratio, and metabolic parameters remain within limits.
Maintaining the correct weight is a practical part of preparing for NDA Physical Requirements. A balanced diet, regular running, and strength training help candidates stay within the prescribed range.
Chest Measurement Requirements
A well-developed and well-proportioned chest is essential.
- Minimum chest circumference (unexpanded): generally 77 cm (some older references mention 81 cm when fully expanded)
- Minimum expansion after full inspiration: 5 cm
The chest should be symmetrical without deformities such as pigeon chest, sunken chest, or asymmetry that could affect physical performance or military bearing. Measurement is taken with the tape at the level of the nipples in front and the lower angle of the shoulder blades behind.
Vision and Eye Standards for NDA
Eyesight standards are strict and vary by service and entry type.
For NDA (10+2 entry – Army)
- Uncorrected vision: maximum 6/36 in each eye
- Best corrected visual acuity: 6/6 in both eyes
- Myopia: not exceeding –2.5 D Sph (with astigmatism limits)
- Hypermetropia: not exceeding +2.5 D Sph
- Colour perception: CP-II
- LASIK or equivalent refractive surgery is not permitted for NDA entry
Navy standards are more stringent for uncorrected vision in some parameters. Air Force Flying Branch demands near-perfect vision (often 6/6 uncorrected or with very limited correction) and CP-I colour perception. Spectacles are generally not accepted for flying duties.
Candidates should get a proper eye check-up early. Night blindness, colour blindness beyond the permitted grade, squint, and active eye diseases are causes for rejection.
Other Important Medical Parameters
The medical board examines the entire body systematically:
- Hearing: Normal hearing in both ears; no significant disease of ear, nose, or throat.
- Dental: Healthy gums and teeth; adequate dental points.
- Spine and limbs: No knock knees, flat feet (beyond permissible limits), bow legs, or spinal deformities that affect function.
- Chest X-ray and investigations: Free from tuberculosis or other pulmonary issues. Routine blood, urine, and ultrasound abdomen/pelvis are performed.
- Skin and general health: No chronic skin conditions, hyperhidrosis of severe degree, or systemic diseases.
- Tattoos: Permanent body tattoos are restricted. Tattoos on the inner face of the forearm (from inside of elbow to wrist) and reverse side of the palm are generally accepted. Tribal tattoos may receive consideration. Facial and other visible tattoos are usually not permitted.
Candidates must be free from any disease or disability that could interfere with efficient performance of military duties in peace or war.
Common Reasons for Temporary or Permanent Rejection
Many candidates receive temporary rejection for correctable issues such as:
- Weight outside the ±10% range
- Under-developed chest expansion
- Minor dental problems
- Ear wax or mild ENT issues
- Borderline vision that can be managed within limits
Permanent rejection occurs for conditions that cannot be corrected within the given time frame or that fundamentally affect fitness (severe flat feet, colour blindness beyond standard, certain cardiac or neurological issues, etc.).
How to Prepare for NDA Physical Requirements
Start early. Daily running (build up to 2.4 km comfortably), push-ups, sit-ups, chin-ups, and rope climbing develop the stamina and strength expected. Maintain a nutritious diet rich in proteins, complex carbohydrates, fruits, and vegetables. Avoid junk food and ensure adequate sleep. Regular medical check-ups help identify and address minor issues well before the SSB medical.
Physical conditioning also builds the mental toughness required for the Academy’s demanding routine.
