Women’s Sports Bras
Find Your Bra Size
Find your bra size with our two-step quiz. Before you start, wear an unlined bra that supports your natural shape—no bralette or padded bra.
First, Measure Your Underbust
Measure around the bra's bottom band, just under the breast. The tape measure should feel snug. Round up to the closest measurement. If you don't have a measuring tape, use a string and a ruler. Follow the above instructions. Lay the string on a flat surface and measure with the ruler.
Second, Measure Your Cup
With the tape measure parallel to the floor, lay the tape across the fullest point of your breast. Measure from the centre of your chest to where your breast tissue ends on one side (where an underwire should sit). Round up to the closest measurement.
Your Nike Bra Size
Based on your answers, this is the bra size we think will fit you best.
Use the charts below to convert your usual bra size into Nike Sports Bra sizes.
Scroll horizontally to see more sizes on each chart.
To get the best fit within our Alpha/Cup size range, find your usual size (XS–3X), then find your usual cup size (A–G). For example, if you typically wear a size Medium and are a C cup, the "M (C–E)" should be your perfect size.
Cup size options: A, B, C, D, E (DD), F (DDD) and G (DDDD).
Three Tips for Finding the Right Fit
Because when it fits, it's a beautiful thing.
1. Check the Straps
Two fingers should fit comfortably between the band and your shoulders.
2. Check the Band
Raise your arms, making sure the band stays in place.
3. Test the Support
Move in it. You should feel comfortable and confident.
