Before you measure

Soft tape measure to hand.
Your best-fitting bra on, ideally non-padded and underwired. Any well-fitting bra will do.
In front of a mirror, so you can check the tape stays level all the way round.

Then type your two measurements below and we'll work out your size.

Tape measure around the underband, directly beneath the bust

1. Underband

Around your rib cage, directly under your bust. Snug, and level at the back.

Tape measure around the fullest part of the bust

2. Bust

Around the fullest part of your bust (about nipple level). Taut, not tight, and level.

Your measured size

Recommended in this style

Enter both measurements to see your size.

Underband. Measure around your rib cage, directly under your bust, keeping the tape level. The chart below turns this into your band size.
Bust. Measure around the fullest part of your bust, keeping the tape taut and level.
Difference. Round any half inch up to the next whole inch, then take your underband measurement away from your bust measurement. Each inch is one cup size (1″ = A, 2″ = B, 3″ = C, 4″ = D, 5″ = DD, and so on).

The underband

The band around the chest should be level front and back. It needs to be comfortable but firm — a good gauge is being able to fit two fingers between the underband and your skin. Any more space and the band is too big, and could cause friction.

The underband is firm and level the whole way round.

Only a one to two inch give — neither too loose nor too tight.

If the underband rides up at the back, the band is too big.

The cups

The cup should contain the whole of the breast, with no creases and no cleavage on show.

Each breast is fully contained.

If the breasts are squashed or cleavage is on show, the cup size is probably too small.

If the fabric is gaping or wrinkling, the cup size is too big.

The shoulder straps

Sports bras come in different styles, usually a traditional U back or racer back. The straps should be adjusted to fit securely on the shoulders with only one to two inch give.

Slide two fingers between the strap and the skin — there should be only a one to two inch give.

If the straps dig into the shoulders, loosen them until the fit is comfortable.

If the straps fall off your shoulders, tighten them so they sit securely.

Then do the bounce test. Jump up and down on the spot — you should feel supported and secure, with the band staying level.
