How to measure your bra size correctly: This is how you find a bra that really fits

A bra can look beautiful and still be uncomfortable for everyday wear. Often, this is not due to the model itself, but to the size or fit. A band that is too loose offers little support, cups that are too small can dig in, and incorrectly adjusted straps take on work that the band should actually be doing. Anyone who wants to correctly measure their bra size and then consciously check the fit only needs a few minutes and a flexible tape measure.

Correctly measuring bra size: two measurements as a starting point

To determine your size, you first need your underbust circumference and bust circumference. Stand as straight as possible and breathe normally. For the underbust circumference, place the tape measure horizontally around your body directly below your breasts. It should be close to your body without digging in uncomfortably.

Then, measure your bust circumference at the fullest part of your breasts. Here too, the tape measure should run horizontally and neither hang loosely nor compress your breasts. These two values form the basis for determining the band size and cup size.

However, you should understand the calculated bra size as a starting point, not an unchangeable rule. Cuts, materials, and sizing systems can differ between brands. Therefore, trying it on is just as important as the tape measure. When selecting high-quality bras for women, it's always worth paying attention to the actual feel in addition to the stated size.

How to tell if your bra really fits correctly

Check the band, cups, and straps together

A good fit results from the interplay of several elements. The band should be firm and run as horizontally as possible around the body. If it rides up significantly at the back, the band size may be too large. The cups should fully enclose the breasts without forming visible gaps or digging in.

The straps also deserve attention. They should support the hold, but not dig deeply into the shoulders. If you have to adjust the straps extremely short for the bra to provide any support at all, it's worth taking another look at the band and size.

• Band: sits securely and runs as horizontally as possible at the back.
• Cups: enclose the breasts without gaps or digging in.
• Straps: rest comfortably on the shoulders and do not dig in.
• Underwire: lies flat against the body without pressing on sensitive breast tissue.
• Movement: the bra remains largely in position even when raising your arms.

If the cup fits, but the band is too tight or too loose, so-called sister sizes can be interesting. In this case, the band size changes along with the cup designation, while a similar cup volume is maintained. Because breast shape also plays a role, a different cut can sometimes work better than another size change.

The same principle applies to combining with high-quality briefs and lingerie: it's not the number on the label that determines whether something fits your body, but comfort, fit, and the feeling when wearing it.

FAQ: Bra size and perfect fit

How often should I remeasure my bra size?

There is no fixed period. Remeasuring is particularly worthwhile if your old bras suddenly fit differently or if your body has changed. Weight fluctuations, hormonal changes, and other physical changes can affect the fit.

Why doesn't the same bra size always fit me across different brands?

Cut, material, cup shape, and sizing systems can differ. Therefore, two bras with the same size indication do not necessarily fit identically. The stated size is an important guide, but actually trying it on remains crucial.

What is more important: cup or band?

Both must fit together. The band provides a significant part of the support function, while the cups enclose and shape the breasts. A perfect cup cannot fully compensate for a band that is too loose.
