This calculator estimates bra size based on bust size and band size (frame size). To ensure accuracy, measure to the nearest ¼ inch or ½ cm. This calculator provides results for the United States, the United Kingdom, European Union, France, Belgium, Spain, Australia, and New Zealand.

Incorrect Bra Fit
Surveys and studies often cite that anywhere between 70-85% of women wear incorrectly fitted bras. While data collection methods between various sources is not consistent and these percentages may be inflated, incorrectly fitted bras are nonetheless a significant issue, evidenced by the number of studies, articles, and complaints surrounding the issues women face due to a lack of size standardization. Studies have revealed that the most common mistake made by women when selecting a bra was to choose too large a back band and too small a cup. Part of the issue is the lack of standardization regarding band and cup sizes. These vary largely between countries, and even manufacturers, making it difficult to use these measures as anything more than an approximate fit. A 34B bra from two different companies, for example, may not fit the same person because of this lack of standardization.

Some signs of incorrectly fitted bras include the band digging into the torso or sliding upwards, red marks, shoulder or neck pain, the breasts overflowing around the edges of the bra, and the bra's center panel not lying flat against the breast, among others.

Bra Size
The two major aspects of bra size are the band size and the cup size.

Band Size (Frame Size)
The band size is the size of the bra band around the torso. However, band sizes come in different measurements in different countries, in that sizes such as small, medium, and large, equate to different measurements. Refer to the table below for some size measurements, though some variation from the published measurements is possible.

Band Size FR/BE/ES EU (Standard EN 13402) US and UK AU, NZ
XXS 75 60 28 6
XS 80 65 30 8
S 85 70 32 10
M 90 75 34 12

3XL 110 95 42 20
4XL 115 100 44 22
5XL 120 105 46 24
Cup Size
The cup size can be calculated using the difference between bust size and band size. Refer to the table below.

In Continental Europe, the cup size is calculated from the bust-to-band difference in centimeters.

Age Calculator of NDA 2026: Check Your NDA Attempts Instantly

Age Calculator of NDA 2026: Check Your NDA Attempts Instantly
The age limit in the NDA exam is very strict, and even a difference of just one day in your date of birth can decide whether you are eligible or not. Use the NDA Age Calculator given below to check within a few seconds whether your date of birth falls within the allowed age window for the upcoming NDA exam. Just enter the same date of birth that is printed on your Class 10 certificate, and the tool will tell you whether you qualify or not. Do not enter any incorrect date of birth.

NDA Age Limit – Current Notification (NDA 2 2026)
These figures have been taken directly from the official UPSC notification for the National Defence Academy and Naval Academy Examination (II), 2026. This exam is for the 158th NDA Course and the 120th Indian Naval Academy Course (INAC), which will start from 1 July 2027.

Candidates must be between 16.5 and 19.5 years of age. Age is fixed according to the course start date, so there is a different date-of-birth range for every exam cycle. A candidate will be eligible only if their date of birth falls between the two dates shown below or on either of those dates.

Exam cycle Born not earlier than Born not later than
NDA 1 2026 2 July 2007 1 July 2010
NDA 2 2026 1 January 2008 1 January 2011

Why Is It Important to Carefully Check NDA Age Eligibility?
The National Defence Academy (NDA) exam is conducted twice a year by the Union Public Service Commission (UPSC). It is the main route for school students to join the Army, Navy and Air Force wings as officers.

NDA age eligibility is decided by your exact date of birth, not by your rounded-off age. UPSC publishes a fixed date-of-birth range for each exam cycle. And you have to check it using your original date of birth itself. This tool helps you check your eligibility, that too for free and easily on CalculatorFlows. If your date of birth falls within that range, you are eligible. If it is even one day outside the range, you are not eligible – no relaxation is provided. This is why simply looking at your age in years is not enough, and the calculator given above matches your exact date of birth with the official age window.

How Is NDA Age Calculated?
The age rule does not work on the basis of the age you calculate yourself, but through a date-of-birth range. Understand it simply as follows:

Check your date of birth exactly as it is printed on your Class 10 certificate.
Select the exam cycle for which you want to apply (NDA 1 or NDA 2).
Check whether your date of birth falls between the two boundary dates of that cycle or on either of those dates (see the current notification section above).
If yes, then you meet the age criteria. If your date of birth is even one day before the earliest date or one day after the latest date, you do not meet the age criteria. The calculator given above automatically performs this check for you.
For this, the best calculator for you is the Age Calculator of NDA.

NDA Educational Qualification
Many students are confused about what the Educational Qualification should be. The minimum educational qualification depends on the wing you choose. Students studying in Class 12 can also apply, but students studying in Class 11 are not eligible. These requirements generally remain the same across different cycles.

Wing Qualification
Army Wing of NDA Class 12 passed (10+2) from a recognised Board or University
Air Force and Naval Wings of NDA Class 12 passed with Physics, Chemistry and Mathematics
10+2 Cadet Entry Scheme in Naval Academy Class 12 passed with Physics, Chemistry and Mathematics
Nationality is also a condition: the candidate should be a citizen of India, a subject of Nepal, or an eligible person of Indian origin who has migrated from the specified countries.

How Many NDA Attempts Can You Get?
There is no maximum number of attempts set for the UPSC NDA exam. Only your age is the actual limit. Since the exam is conducted twice a year and the eligible age window is from 16.5 to 19.5 years, most aspirants get approximately 4 to 5 chances in total.

This is why students who are born in the starting months of the eligible age should plan carefully. For them, a particular cycle may be one of their last valid attempts, so it is better to confirm eligibility in advance with the help of the calculator and the official notification.

Important Age Rules for the NDA Exam
Different rules apply to every candidate, regardless of which category or wing they belong to. These rules generally remain the same across different cycles, but you should still confirm them according to the latest notification.

Rule Detail
Age band 16.5 to 19.5 years
Age relaxation None — same limits for General, SC, ST, OBC and all others
Marital status Only unmarried candidates are eligible
Gender Both male and female candidates are eligible
Date of birth proof Only the Class 10 / Matriculation certificate is accepted
