How the Champion guide works

Use the Champion calculator

This page is a label conversion, not the manufacturer’s own measurement calculation. Your general starting size is translated into the brand’s published labels.

Translates your general starting size into this brand’s published chart labels. It does not calculate a size using the manufacturer’s own body-measurement method.

Source scope and chart notes

Uses the Women’s Sports Bras table, not clothing bust ranges. Preserves printed combined labels such as XXL/1X and XXXL/2XL. Printed dashes remain unavailable. Label conversion of the general US band/cup starting estimate only, not a manufacturer body-measurement calculation or a fit guarantee. Confirm the chart on the specific style.

Let’s find your starting point

Measure over a t-shirt or a lightly lined bra, or without one—whichever feels right.

Fit profile (optional)

For try-on tips only. It does not change your size or result, and it clears on reload or when you delete your measurements.

Issues you notice now
Your measurements are only used in this page. Nothing is sent or saved.
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.
