To measure your size it is best to wear an everyday well-fitting non-padded bra and use a fabric / flexible tape to measure in centimetres.

To help you further, brand specific size guidelines have been added to the product images of some of our sports bras. Please also check these before ordering.

Back Size – Underbust measurement

Your bra back size is determined by your under bust measurement. Place tape
measure around your body, underneath the bust, in line with the bottom of your bra’s hook & eye. The tape should be taught but not uncomfortable.

Cup Size – Overbust measurement

Place the tape measure loosely over the fullest part of your breasts (usually over the nipple). This is best done when wearing a bra. Ensure the tape measure is at the same height across your back as across your bust.

Your back size can be different to your clothing size as it relates to the width of your back and diaphragm. A lady may wear size 12 clothes and a size 14C bra.

Now look at the Bra Fitting Chart below. First find your underbust measurement (Back Size) in the left hand column, round up to the nearest cm if required. Then find the corresponding Australian/NZ size in the grey column. This determines your back size.

Once you have your back size, follow the row along until you find your cupsize measurement, again round up to the nearest cm if required. This will determine your cup size.

Crop Tops

Crop tops can fit differently to cupped bras. Generally speaking they are more similar to women’s clothing sizes.

XS = 8 S = 10 M = 12 L = 14 XL = 16 XXL = 18

However the correct size can be more accurately determined using your under bust and over bust measurements in the table below. To understand how to take these measurements please see the explanation above.

Sports Bras Direct recommends crop tops for cup sizes A-D only. You must also check the specific style of crop top suits the level of impact you require. Breasts that are bigger than a D cup require more specific support from a cup size sports bra.

Each Brand has a slight variation in their actual measurement guidelines for crop tops, so we have summarised the individual Brand’s advice in the table below.
