How the Playtex guide works

Use the Playtex calculator

Follows the manufacturer’s instructions to round the underbust upward to an even band, then compares the bust measurement with that band to choose the cup label.

A note on fit

A number can guide you. Your comfort gets the final say.

Bra sizing isn’t consistent from one label—or even one style—to the next. Think of this as a useful first try, not a rule you have to fit.

Try the whole bra, not just the label

The band should feel secure without digging in; cups and straps should feel comfortable as you move.

Nearby sizes are worth a look

If your first try is close but not quite right, compare neighboring sizes and another style or cut.

Your body isn’t the problem

Brands use different patterns, fabrics, and size ranges. A mismatch says more about the garment than about you.
