NDA Eligibility Criteria: Age Limit, Height, and Physical Standards for Boys & Girls
The National Defence Academy (NDA) is one of India’s most prestigious institutions for students who dream of becoming officers in the Indian Army, Indian Navy, or Indian Air Force. Every year, thousands of young aspirants apply for the NDA examination, but only candidates who meet the required eligibility and medical standards can move forward in the selection process.
Both boys and girls can apply for the NDA examination. However, candidates must satisfy specific requirements related to age, educational qualification, marital status, height, weight, eyesight, and overall physical fitness.
In this guide, we explain the NDA eligibility criteria, age limit, minimum height, and physical standards for male and female candidates.

What Is the NDA Exam?
The NDA and Naval Academy Examination is conducted by the Union Public Service Commission (UPSC). It provides young candidates with an opportunity to join the officer-training pathway for the Indian Armed Forces after Class 12.
Candidates can apply for different wings, including:
- Indian Army
- Indian Navy
- Indian Air Force
- Indian Naval Academy
The selection process generally includes a written examination, SSB interview, medical examination, and final merit list.
Meeting the academic eligibility requirements is only the first step. Candidates must also satisfy the prescribed physical and medical standards.

NDA Age Limit for Boys and Girls
The general age range for NDA entry is approximately 16.5 to 19.5 years at the commencement of training.
The age criteria are the same for male and female candidates. However, UPSC normally specifies eligibility through exact dates of birth rather than only mentioning a general age range.
Important Points About the NDA Age Limit
Candidates should remember the following:
- Both male and female candidates can apply.
- Candidates must fall within the exact date-of-birth range given in the official notification.
- The candidate must be unmarried.
- Candidates are expected to remain unmarried during the required training period.
- Age relaxation is generally not provided for the NDA examination.
Since the exact eligible birth dates change with each NDA examination, candidates should carefully read the latest official notification before applying.
NDA Educational Qualification
The educational qualification depends on the wing for which the candidate is applying.
For the Army Wing of NDA
Candidates must have passed Class 12 or an equivalent examination from a recognised board.
Students appearing in Class 12 may also be eligible to apply, subject to the conditions mentioned in the official notification.
For the Air Force and Naval Wings
Candidates must have passed or be appearing in Class 12 with:
- Physics

Students who have not studied the required science subjects should carefully check their eligibility before selecting Air Force or Naval preferences.

NDA Height Requirements for Boys
Height requirements can vary depending on the service branch and other medical conditions.
As a general reference, the minimum acceptable height commonly considered for male candidates is around 157 cm for many entries.
However, different standards or concessions may apply based on:
- Service branch
- Flying duties
- Region of origin
- Specific medical guidelines
Candidates applying for flying roles may have additional anthropometric requirements related to sitting height, leg length, and thigh length.
NDA Height Requirements for Girls
For female candidates, the minimum acceptable height is generally around 152 cm for many entries.
However, candidates should understand that the final standard depends on the official medical guidelines applicable to the particular service and entry.
Height concessions may apply in certain cases according to official rules.
NDA Height Standards: Quick Comparison
| Category | General Minimum Height Reference |
|---|---|
| Male Candidates | Around 157 cm |
| Female Candidates | Around 152 cm |
These figures should be treated as a general guide. Candidates must refer to the latest official medical standards because requirements can vary by service branch and category.
NDA Height and Weight Standards
Meeting the minimum height requirement alone is not enough. A candidate’s weight should also be proportionate to:
- Height
- Age
- Body build
Candidates who are significantly underweight or overweight may require further medical evaluation.
The medical board assesses whether the candidate is physically capable of handling the demanding training and duties of the Armed Forces.
Tips to Maintain a Healthy Height-Weight Balance
Aspirants should:
- Follow a balanced diet
- Avoid crash dieting
- Maintain a regular exercise routine
- Get adequate sleep
- Drink sufficient water
- Avoid unhealthy weight-gain or weight-loss methods
Candidates should focus on long-term fitness rather than making extreme changes immediately before the medical examination.
NDA Physical Standards for Boys and Girls
Candidates must be physically and mentally fit according to the prescribed Armed Forces medical standards.
The medical examination may assess:
- Height and weight
- Vision
- Hearing
- Dental health
- Chest and respiratory health
- Bones and joints
- Spine and posture
- Heart and cardiovascular health
- General physical development
A candidate should be free from medical conditions that may interfere with military training or future service.
NDA Eyesight Standards
Vision is an important part of the NDA medical examination.
The exact eyesight requirements may differ according to:
- Army entry
- Navy entry
- Air Force entry
- Flying or ground duties
Candidates may be examined for:
- Distant vision
- Near vision
- Colour perception
- Night vision
- Eye alignment
- Refractive errors
Candidates interested in the Air Force, especially flying roles, should pay particular attention to the specific visual standards.
Common Medical Reasons for Rejection
Some candidates clear the written exam and SSB interview but face difficulties during the medical examination.
Common medical concerns can include:
- Being significantly underweight or overweight
- Vision outside permitted limits
- Colour vision problems for certain branches
- Knock knees
- Flat feet in disqualifying cases
- Significant spinal deformities
- Serious dental problems
- Hearing difficulties
- Chronic medical conditions
- Certain past injuries affecting physical function
Not every minor condition results in permanent rejection. The final decision depends on the official medical board and applicable standards.
Are Tattoos Allowed in NDA?
Tattoo rules are governed by the applicable Armed Forces policy.
Permanent tattoos may be permitted only under specific conditions and at approved body locations. Certain traditional or customary tattoos may also be considered according to official rules.
Candidates with permanent tattoos should carefully review the latest tattoo policy before appearing for medical examination.
Physical Fitness Preparation for NDA
The NDA selection process demands stamina, discipline, and overall fitness. Candidates should start physical preparation early.
A practical fitness routine may include:
- Regular running
- Push-ups
- Sit-ups
- Squats
- Pull-ups
- Skipping
- Swimming, if available
- Mobility and flexibility exercises
Beginners should gradually increase the intensity of their training instead of suddenly attempting an extreme workout routine.
Sample Weekly Fitness Routine
| Day | Activity |
|---|---|
| Monday | Running and bodyweight exercises |
| Tuesday | Strength and mobility training |
| Wednesday | Running and core exercises |
| Thursday | Light recovery and stretching |
| Friday | Running and strength training |
| Saturday | Sports, swimming, or endurance activity |
| Sunday | Rest and recovery |
Consistency is more important than a single intense workout.
NDA Selection Process
Candidates who meet the eligibility criteria generally go through the following stages:
1. Written Examination
The written examination includes Mathematics and the General Ability Test.
2. SSB Interview
Candidates who qualify in the written examination are called for the Services Selection Board interview. The SSB assesses qualities such as intelligence, communication, teamwork, decision-making ability, confidence, leadership potential, and personality.
3. Medical Examination
Recommended candidates undergo a detailed medical examination to determine whether they meet the required Armed Forces medical standards.
4. Final Merit List
Final selection depends on the candidate’s performance, medical fitness, merit position, service preferences, and available vacancies.
