Do you know your bra size? Or do you always end up buying bras that don’t fit the size of your chest? Knowing the size of your bra is easy; through a series of simple steps you can obtain it.

In this article we will explain how to know which bra size is yours; to know it you will only need a soft tape measure. Finally, we will explain what 20 types of bras exist depending on a series of parameters and characteristics (shape, complements, size…).

Bra sizes: how do you know what size you are?

First of all, we will differentiate two concepts in relation to our bra: the size, which indicates the measurement of the contour of the torso, and which is a number (for example size 90) and the cup, which indicates the volume of the chest, and which is a letter (for example cup B). These two parameters make up your bra size, and are very easy to calculate.. Let’s get on with it.

Not all women wear bras these days. However, if you are one of those who does, knowing the size of your bra will help you buy the one that best fits your body. This will make it more comfortable for you and not cause you any discomfort.

It’s true that not all brands of underwear (or their collections) are the same, and that’s why sometimes the same size and cup can vary from one bra to another. In general, however, the sizes usually correspond between different brands.

The steps to calculate your bra size and cup are as follows.

1. Measure the contour of the back at the height below the chest.

First of all you must measure the contour of your back. Thus, the first step you need to take to find out your bra size is to surround the contour of your back below your breasts with a meter (you can use a soft tape measure).

Round up that number and write it down (e.g. 100). This number corresponds to the outline of your chest, i.e. the number that appears in the size (size 90, 95, 100…).

2. Measure the contour of the back to the nipples

The second step is to use the meter (soft tape measure) to surround your back at the level of your nipples (without pressing) (the same thing you have done before but this time above the nipple, not below the chest). I mean, encircle your whole back, from the back to the front. Write down the resulting number (e.g. 85).

3. Obtain the cup by subtracting the two previous figures

Now we must subtract from the first number (obtained in step 1) the second number (obtained in step 2). In this case, following the example we set, we will subtract: 100 – 85 = 15. We get 15, which is 15 cm.

This 15 is the difference between the two measures, and corresponds to the measure of our cup (A, B, C, D…) in centimeters. When we buy underwear, we see on the label how the cup accompanies the bra size (e.g. 100 B). But what numbers correspond to each cup? Let’s go see him:

  • Cup A: between 12 and 14 cm
  • B cup: between 14 and 16 cm
  • C cup: between 16 and 18 cm
  • D cup: between 18 and 20 cm
  • E cup: between 20 and 22 cm
  • F Cup: between 22 and 24 cm
  • G cup: between 24 and 26 cm
  • H cup: between 26 and 28 cm

The cup of the bra

As we indicated, the cup of the bra indicates the volume of our chest (if it is more or less wide). Most often we have an A, B or C cup (these are the most common cups), but we can have up to an H cup, depending on the size of our chest and back.

Thus, the farthest letters (F, G, H…) correspond to larger breast volumes, and the differences between the contour of the back from below the chest and the contour of the back from the nipple are larger. On the other hand, the first letters (A, B…) correspond to breasts with less volume.

Types of fasteners

Beyond the size, there are different types of bra. Each of them will be ideal for one occasion or another (sport, walking…) and for one type of dress or another (gala dress, wide t-shirt…). In other words, there are several types of bra, which can be adapted to our needs and preferences. These, in addition, are classified according to six parameters. Let’s get to know them.bra types

1. According to the central bridge

The central bridge is the part of the fastener that joins the two pieces. Depending on whether the bridge is wide or thin we find two types of fasteners: “plunge” type (with the thin central bridge) and “no plunge” type (with the wide or thick central bridge).

2. Depending on the coverage of the cup

Depending on whether the cup is larger or smaller, there are four more types of bras: “full cup”, “balcony” (large cup but a little more low-cut than the previous one), “balconette” (cup with a more rectangular shape) and half a cup (similar to the previous one).

Depending on the position of the braces

Depending on the position of the straps, there are four other types of bras: half cup “balconette” (rectangular cup with normal straps, one in each cup without crossing), “full cup balcony” (wide and large cup, with normal straps), multipositional straps (can be extracted (the two or one), cross, etc.) and without straps (are simply strapless bras).

4. Depending on the placement of the chest

Depending on the placement of the breast inside the bra, we find the following types of it: “push up” (elevates the chest), reducer (reduces/hide), with lateral support (to hold it better) and the rest (normal).

5. According to the band

According to the band of the bra, we find three types: “bandless” (without band), with half band and with band (in the latter case the cups have a more rectangular global shape).

6. Depending on the type of filling

Finally, depending on the type of padding the bra is wearing (or if it is not), we can classify the bras into: “foam” bras (with a thin layer of padding), “spacer” (with a three-dimensional net inside the bra, which adapts to the shape of the breast) or without padding.
