How To Measure A Bra Size

There is not one hard and fast rule that says one size fits all – not all bra types, I mean. It is worth mentioning that you must try a bra of every type before you are sure of the size. There would not be a radical difference in the sizes for every type/brand, but there would, most definitely, be some. Research shows that 80% women are oblivious to their true bra size. And for all you know, you might be wearing an incorrect one as we speak. The most obvious aspect we all go wrong with is the band size, amongst several others. So, here’s what determines your size.

Step 1: Measure Your Band Size

  • Wrap the tape around your chest, where your band sits, and ensure that it is snug, but not too tight or loose.
  • Round it off to the next even number if it’s an odd measurement or in fractions. For example, if the measurement is 33 or 33.5 inches, the size will be 34. Or, for 35, try both 34 and 36, again depending on your cup size.
  • Make a note of this final number.

Step 2: Measure Your Cup Size

  • Wrap the tape loosely around the fullest part of your breast.
  • A simple option is to measure it at the nipple level – this invariably gives an accurate number.
  • Round it off to the nearest or next whole number.
  • Make a note of this final number.

Things To Remember

Go braless or wear a non-padded bra while you get your measurements done. Or, wear something light like a T-shirt and avoid sweaters, hoodies, jackets, or anything that is thick.

Be vigilant while getting your measurements, especially if you having sagging or larger breasts. Go one step further and get a second opinion if you want to be extra cautious. There have been instances where the difference in sizes was rather alarming when a measurement was taken the second time around.

Get a one-time professional fitting done. Experts say that the measurements are generally more accurate when you let someone else do your fitting.
As a rule of thumb, your bra should fit snugly around your body. It should neither be too tight nor too loose.

When you go up or down your bra size, the cup size also differs. For example, if your size is 34B, a bigger size for you would be 36A. If you want a smaller size, go for 32C.

It is easier to determine your band size first and then map it to your cup size.
Remember that your breasts should sit approximately midway between your elbows and shoulders when you wear a bra.

The cups will do the heavy lifting, and the straps will support them, so do not forget to adjust the straps.

How To Find The Right Bra

Choosing the right bra is nothing but knowing your exact bra size for every type. However, you can’t just magically arrive at this number. You need to work backward and connect a few dots to get there. Here are a few pointers.


Move your arms around like a windmill to see if your breasts are falling out or hanging from the bottom or if your bra is riding up. In that case, try adjusting the straps first. Otherwise, you will need to go for a smaller cup size.

If your bra straps are pinching or digging into your shoulders, or if your breasts are spilling out, making the two of them look like four, you need a bigger size.


  • Bend forward when putting on a bra so that everything goes into the cup and nothing hangs under the wire.
  • Make sure the cup is taut and there is no extra room.


  • Always hook your bra at the closest (first) eye and run two of your fingers under the band. Your fingers should slide comfortably. The bra will loosen up with time, and you can hook it on the next eye then.
  • If your bra is riding up your back and you’re always pulling it down, you need a smaller band size.
  • Center
  • The center part of the bra should sit just perfectly. It should not stick out or poke your skin.
  • Now that you know how to choose the right bra that fits you perfectly, what are you waiting for? With the number of options out there, bra shopping should not be that bad. There is one for everyone.

  • Enhance the shape and silhouette.
  • Prevent sagging of breast tissues.
  • Avoid pain and discomfort.
  • Increase confidence.

Q3. What is the best bra to wear?

A simple T-shirt bra is ideal for everyday use. These bras give you a smooth line underneath your clothes, as they're either seam-free or they have barely-there seams. These bras don’t have any extra embroidery or lace, so they simply vanish under tight fitted tops and dresses.

Q4. What is ABCD in bra sizes?

The letters - like A, B, C, D - stand for cup sizes. The numbers - like 32, 34, 36, 38 they tell you the band size – that's the part of the bra that goes around your torso. For instance, a 34A means that your boobs are an A cup and that your bra is 34 inches around.

Example: 37 inches (bust) – 34 inches (band) = 3 inches. That’s a 34C.

Q5. What is the difference between cup size & bra size?

Your cup size is the difference between your chest size and your bust line measurement while your bra size is your band size with your cup size.

Everyone has a unique body type, which means sometimes you may not find accurate bra size measurement using the regular bra size chart. Here, you can switch to sister sizes. Basically, these are alternate bra sizes where the cup volume stays the same even though the band size and cup letter change. For instance, if you are a 34 B, there is a good chance that a 32 C or a 36 A will fit you. 32 C will have a shorter band size and 36 A will have a longer one, so you can figure out what fits you better.

Q7. What happens if you wear the wrong size?

  • You can put yourself at a risk for plethora of problems, such as
  • Pain and discomfort in the breast tissues.
  • Straps start digging into your shoulders.
  • Back, neck and headache.

  • Your bra hinders your movement.

Q8. How can I tell if my bra fits properly? Let’s check each part of the bra.

  • The back band should lay straight on the back without riding up.
  • The centre gore should sit flat against your sternum.
  • The underwires should fully encircle the breasts.
  • Your breasts shouldn’t spill out of the cups and the cups shouldn’t have extra room either.

Q9. Am I wearing my bra correctly? Let’s double check.

  • As long as you’re following these steps, you’re good.

The average recommended time to revamp your bra closet is about six months to a year depending on your usage.
