How the Freya guide works

Use the Freya 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.

Source scope and chart notes

Official international label chart only. UK/ROW labels are used; the US storefront uses US labels. Not every listed band and cup combination is offered in every 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.
