The difference between bra size and bra cup

It is common for there to be some confusion between the terms "size" and "cup" when talking about bras. Although they are interrelated, they are not the same and measure different parts of the breast:

Sizing: sizing refers to the measurement of the band around the torso just below the bust, i.e., it measures body contour. This measurement is expressed in numbers and is generally found in a range of standard sizes (85,90,100, etc.).

Cup: The bra cup refers to the size and shape of the part that covers and supports the breasts. It is measured at nipple height and is identified by letters (B,C,D, etc.). Therefore, what the letter on the bra label means is this measurement.

In short, the size refers to the contour of the band and the cup refers to the size and shape of the breasts in relation to the band.

It is important to keep in mind that finding the right bra size involves correctly combining both measurements for optimal fit and proper support.

How to measure yourself to know your bra size?

To measure your size, place the measuring tape under your chest, at the level of your ribs, and parallel to the floor. Make sure the tape is not too tight.

To find your cup size, place the tape at the level of your nipples, parallel to the floor and with your back straight. Check that the tape does not bend.

Calculate your bra size

To calculate it properly, with your measurements of underbust and contour, you have to follow the following table:

First, we recommend you to identify the cm of underbust to identify the size (number of the top row) and then within the same column find the cup that fits your measurements.

In addition, there are bra size equivalences according to cup and underbust variation, you can use several cups and sizes, all within the column of your reference size.

Your bra size in different countries

When we are going to buy a bra, especially online, it is advisable to pay special attention to the country of reference.

In all countries the sizes are not measured in the same way and there are different equivalences. For example, your bra size in Spain, France and Portugal is measured in the same way, but not in the rest of Europe, Italy or America.

Here are the equivalences in the different countries. We recommend you to look for the size of your country first and then the international size and then you will be able to find out more easily.

It is important to take the measurements explained above accurately and carefully to obtain optimal results, and choose the bra that best suits you.
