NDA Medical Test Standards: Fitness Criteria for Army, Navy, Air Force
The NDA medical test standards are among the most critical - and most misunderstood - aspects of the National Defence Academy selection process. Thousands of candidates qualify the written examination every year only to face disqualification at the medical board stage due to avoidable gaps in preparation or awareness.
This article provides a complete overview of NDA medical fitness criteria across all three services - Army, Navy, and Air Force - covering height and weight requirements, eyesight standards, common disqualification reasons, and how to prepare effectively. Read on to ensure you walk into your medical board with full confidence.
What Are the NDA Medical Test Standards? A Complete Overview
The NDA medical examination is conducted by a Medical Board after a candidate clears the written exam and SSB Interview. It assesses overall physical and mental fitness across multiple parameters including vision, hearing, dental health, orthopaedic condition, and general systemic health. A candidate declared medically unfit can appeal, but prevention through early awareness is far more effective.
Candidates often assume the medical test is a formality - this is one of the most damaging misconceptions. The NDA medical standards are stringent and service-specific, meaning the criteria for Army, Navy, and Air Force differ in key areas such as vision and height.
Core Parameters Checked in NDA Medical Examination
- Height and weight (with BMI correlation)
- Eyesight and colour vision
- Hearing and ENT fitness
- Dental and oral health
- Orthopaedic fitness (spine, limbs, flat foot)
- Cardiovascular and respiratory health
- Skin and general systemic conditions
For a structured start to your preparation, the 3 Months Preparation Course for NDA on EduRev covers both written exam content and awareness resources to help candidates plan holistically.
NDA Physical Fitness Criteria for Indian Army Candidates
For Army candidates, the minimum height requirement is 157.5 cm. Weight must be proportionate to height and age, and candidates are assessed on a standard height-weight chart. A common mistake is ignoring body composition - being overweight or significantly underweight can both lead to rejection.
Chest measurement is also evaluated for Army candidates. The minimum chest measurement (unexpanded) is typically around 77 cm, with a minimum expansion of 5 cm. Flat foot (pes planus) is a frequent cause of rejection for Army aspirants, so candidates should get this evaluated well in advance by an orthopaedic specialist.
NDA Medical Standards for Navy: Height, Weight, and Vision Norms
The NDA medical fitness criteria for Navy are slightly more demanding in terms of height. The minimum height for Navy candidates is 157 cm, while for candidates seeking the Naval Aviation branch, the requirement rises to 162.5 cm. Weight must correspond to height as per the approved naval medical standards.
Navy candidates must have good distance and near vision. The acceptable vision standard (with glasses) for Navy is 6/6 and 6/9 in better and worse eye respectively, though standards for specific roles may vary. Colour blindness is a disqualifier for most naval branches.
NDA Air Force Medical Requirements: Eyesight and Physical Standards
The Air Force has the most stringent NDA medical standards among all three services, particularly for vision. Candidates aspiring to be pilots must have uncorrected distant vision of 6/6 in both eyes. Even minor refractive errors that are acceptable in Army or Navy can lead to disqualification for the flying branch.
Height for Air Force candidates must be between 152.5 cm and 182.5 cm, while leg length, sitting height, and thigh length are also assessed - parameters unique to Air Force that many candidates are unaware of. These anthropometric measurements determine whether a candidate can safely operate an aircraft cockpit.
Height and Weight Requirements in NDA Medical Examination
Height and weight are among the first checks performed in the NDA medical examination process. The NDA height requirement varies by service and region - candidates from certain hill regions and specific tribal communities are granted a relaxation of up to 5 cm in height.
| Service | Minimum Height (cm) | Special Note |
|---|---|---|
| Indian Army | 157.5 | Chest expansion minimum 5 cm |
| Indian Navy | 157 | 162.5 cm for Naval Aviation |
| Indian Air Force | 152.5 - 182.5 | Leg length and sitting height also checked |
NDA weight requirements are assessed against standardised age-height charts. Being underweight is as disqualifying as being overweight, so candidates should monitor their body mass index well before the medical board date.
NDA Eyesight Standards: Vision Requirements Across All Three Services
NDA eyesight standards are perhaps the most commonly searched medical criterion, and for good reason - many candidates discover vision-related disqualifications only at the board stage. The NDA eye test standards differ significantly across services.
- Army: Distant vision 6/6 in better eye and 6/18 in worse eye (correctable to 6/6 and 6/6 with glasses for hypermetropia up to +3.5D)
- Navy: Distant vision 6/6 and 6/9 (corrected); near vision N5 in better eye and N10 in worse eye
- Air Force (Pilot): 6/6 uncorrected in both eyes; myopia and hypermetropia strictly assessed
NDA colour blindness criteria apply across all three services - candidates with colour vision deficiency are typically disqualified from combat and flying roles. The Ishihara test is used to assess colour perception during the medical board.
Revision Tools for Medical and General Preparation
Visual learning tools can significantly help in retaining complex criteria and concepts. EduRev offers several resources designed for NDA aspirants who prefer structured, concise formats.
Common Medical Disqualification Criteria in NDA Medical Test
Understanding NDA medical disqualification criteria helps candidates identify and address potential issues months before their board. Below are the most frequent NDA medical rejection reasons that candidates encounter.
Common Mistakes Candidates Make Regarding Medical Fitness
- Ignoring flat foot early on: Pes planus (flat foot) is a common NDA medical unfit criteria for Army, yet many candidates only discover it at the board stage instead of getting it corrected through exercises beforehand.
- Assuming spectacles are always acceptable: Candidates assume corrected vision always passes - but Air Force (pilot) roles require uncorrected 6/6 vision, making this a serious misconception.
- Neglecting dental fitness: Missing teeth, advanced cavities, or impacted wisdom teeth can lead to rejection. Dental fitness is checked but rarely prepared for.
- Undiagnosed colour blindness: Candidates who haven't had a formal colour vision test may be caught off guard at the medical board.
- Skin conditions like psoriasis or eczema: Chronic skin diseases fall under diseases that disqualify NDA candidates, yet they are seldom mentioned in general preparation guides.
How to Prepare for NDA Medical Examination: Tips and Checklist
Preparing for the NDA medical examination is not just about physical fitness - it involves systematic self-assessment and early intervention. Candidates should begin their medical fitness preparation at least six months before the anticipated board date.
- Get a comprehensive eye check-up including colour vision and refraction assessment
- Consult an orthopaedic specialist for flat foot, knee alignment, and spine curvature
- Maintain a consistent diet and exercise routine to achieve optimal NDA height and weight standards
- Visit a dentist for any pending fillings or extractions
- Get a general health check-up covering blood pressure, heart, and respiratory parameters

Practice and Assessment Resources
Consistent practice across the written examination helps candidates stay on track during the entire selection process. Use these EduRev resources to strengthen your overall NDA preparation.
NDA Medical Test Procedure: What to Expect During the Examination
The NDA medical board examination is typically conducted at designated Military Hospitals or Service Selection Centres. The procedure is multi-day and involves specialists from different medical departments examining each candidate in sequence.
On Day 1, general physical measurements - including NDA body measurement criteria like height, weight, and chest - are recorded. Subsequent days cover ENT, ophthalmology, orthopaedics, dental, and general medicine. Candidates found temporarily unfit may be placed under review with a stipulated period to address the issue.
Difference in Medical Standards for Army, Navy, and Air Force in NDA
The difference in NDA medical standards for Indian Army, Navy, and Air Force is most apparent in vision, height thresholds, and anthropometric requirements. Army standards are relatively more flexible on vision correction, Navy adds specific branch-based requirements, while Air Force demands the highest physical precision for flying roles.
Subject-Specific Preparation Courses
Building strong subject knowledge alongside physical preparation is essential for clearing the NDA selection comprehensively. These EduRev courses address the core written exam subjects.
For candidates who need an accelerated study plan covering both subjects and fitness awareness, the Crash Course for NDA on EduRev offers a focused, time-bound approach to cover all major topics before the examination.
Frequently Asked Questions on NDA Medical Fitness Criteria
Can I appear for NDA if I wear glasses?
Yes, for Army and Navy, corrected vision within permissible limits is acceptable. However, for Air Force pilot roles, uncorrected distance vision of 6/6 in both eyes is mandatory. Candidates with myopia beyond the permissible limit will be declared medically unfit for flying branches.
Is flat foot a permanent disqualification?
Mild flat foot may be accepted with proper assessment, especially for Navy and Air Force. However, Grade 2 or Grade 3 flat foot (pes planus) is typically disqualifying for Army ground roles. Early physiotherapy and corrective exercises can help in borderline cases.
What happens if I am declared medically unfit?
Candidates have the right to appeal to a Review Medical Board. The appeal must be filed within the stipulated timeframe mentioned in the rejection letter. For certain correctable conditions, candidates are given time to seek treatment before reassessment.
Are there any hearing test standards for NDA?
Yes, NDA hearing test standards require candidates to have no significant hearing loss. Candidates must be able to hear a forced whispered voice at a distance of 610 cm in each ear. Any use of hearing aids is a disqualifier across all three services.
