Have you ever had the feeling that your bra is squeezing you or that your breasts seem to be escaping somewhere? If so, you're not alone. Many women wear the wrong bra size without even realising it, which can cause discomfort, pain and even long-term health problems.

But don't worry, because in this article we'll teach you how to calculate the ideal size for your bra. So get ready to say goodbye to bras that don't fit you well!

Why is it important to calculate the size correctly?

Calculating the correct bra size is crucial to ensure comfort and proper support for your breasts. If you wear a bra that doesn't fit you well, you can experience a number of complications, such as neck and back pain, chafing, skin irritation or even long-term posture problems.

What's more, wearing a bra that isn't your size negatively affects the shape and appearance of your breasts, which can lower your self-esteem and confidence. That's why taking the time to calculate the ideal size is essential if you want to feel comfortable and secure in your underwear.

What's the difference between cup A, B, C, D?

Bra cups "A, B, C, D…" represent different cup sizes, with A being the smallest and F the largest. The difference between each of these cups lies in the difference between the bust circumference and the circumference of the bra band.

The bra measurement is taken below the bust, while the bust measurement is taken at the fullest part of the bust. The cup letter is determined by the difference between these two measurements.

In general, cup A is the smallest and usually corresponds to a difference of 2 cm between the measurements. Cup B corresponds to a difference of 5 cm, cup C to a difference of 7 cm and cup D to a difference of 10 cm.

It's important to keep in mind that bra brands can vary slightly in the shape and size of their cups, so one brand may have a different cup size than another. What's more, cup size can also vary depending on the bra style, since some styles may have more or less coverage than others.

How to know which cup type you are?

The first thing you should do is go to your wardrobe and look for your best bra, preferably one without push-up or padding. Then note down the size and once you have it on, start measuring yourself and compare the measurements with the bra size. If it fits perfectly, then you chose the right size.

On the other hand, once you have these measurements, you can use a bra size chart to determine your cup size. Cup size is determined by subtracting the band measurement from the bust measurement and comparing the result with a size chart. For example, if your band measurement is 86 cm and your bust measurement is 96 cm, the difference is 10 cm. Which corresponds to an A cup.

Remember, bra sizes can vary between brands and styles, so you may need to try several sizes and styles before finding the one that fits you best.

Do it this way step by step

Before you start, you should know that bra sizes are made up of two fundamental values, known as cup and size. When we talk about size we're referring to numbers like (80, 90, 100…) and when we talk about cup we're referring to the letter (A, B, C, D, E…).

That said, let's get started!

Step 1: Calculate the size

Measure the circumference below your chest with a measuring tape. It's important that the tape is completely firm, but not tight. Then add 15 cm to the number you've marked.

Your size will correspond to the rounded figure closest to the number obtained.

For example: 74 cm + 15 = 89 cm. The ideal size would then be 90.

Step 2: Measure at nipple height

Now, it's time to calculate the letter of your bra. When we talk about the letter, we're referring to the volume of the breast in relation to the circumference. The letters are classified from A, which is the smallest breast, to F, which would be the largest breast, meaning that the further away the letter, the more volume the breast has.

Step 3: Do a subtraction to get the letter

The cm you obtain in step 2 should be subtracted from the figure obtained in step 1, but you must do it before adding the 15 cm. Once the subtraction is done, you'll need to look at the equivalence table to finally establish which letter it is.

For example: 89 cm - 74 cm = 15. The result corresponds to a B cup.

Benefits of wearing the correct size

Wearing the correct bra size can have several benefits for your health, comfort and appearance. Here we present some of them:

Wearing the correct size can give you great comfort, plus you'll prevent the bra from shifting and making you feel uncomfortable throughout the day. The right bra will give you the ideal support for your breasts, which can help you reduce back pain and improve your posture. If you wear the correct size, your shoulders won't be hunched and your back will stay straight thanks to the support your chest receives. It can improve the appearance of the bust and your figure in general, which can boost confidence and self-esteem.Wearing the wrong bra size can cause health problems such as neck and back pain, skin irritation and respiratory problems. By wearing the correct size, you'll reduce the stress on the bra and prevent it from stretching or becoming deformed over time, which can prolong its lifespan.The ideal size immobilises the breast and prevents the breaking and loss of flexibility of the Cooper's ligaments, and it also prevents sagging. A bra that gives you enough support while you exercise will let you enjoy your routine, since, if it were too loose or too tight, it would cause you discomfort.

That's why it's so important that you take the time you need to find the right size, since this way you can make sure the bra fits perfectly and gives you better support.

It's important to select the correct size, since a bad choice can significantly affect comfort, support and the health of the breasts and back. A bra that's too small can cause pain and pressure on the breasts, as well as on the back, while one that's too big may not provide adequate support and cause the breasts to move uncomfortably.

If you wear exactly the size you need, you'll be able to improve your posture and the appearance of your bust, which in turn can boost your confidence and self-esteem.
