Measured Size by Measured Size

Measured Size turns your measurements into each store's own bra size.

Measure your underbust and bust once, in inches or centimeters. Then, on a bra listing, click the Measured Size icon. It reads that listing and shows:

• Your size in the listing's own labels: 34DD, 34E, 85E, M, Medium Plus, S (D-DD), and so on.
• Whether that size is in stock, when the listing says so.
• How sure it is, as a short rating, with the reasons one click away.
• When your size is sold out: a true sister size, one band away with the same cup volume, marked as a different size.
• When nothing on the listing is close: "Not available here", with the closest size in stock named, rather than a guess.

How it decides
Your size comes from your own measurements, translated into each store's words: letter sizes, UK and EU sizes, cup groups and odd labels. A brand's chart is read for the labels it uses. When it can't tell, it says so.

Where it works
Major US department stores and online marketplaces, and many brands' own stores. On other shops it reads what it can, and on pages it can't read it says so.

On Firefox for Android
On a major store's bra listings, a small "Measured Size: find my size" button on the page opens the card. It reads nothing from the page to decide where to show, and you can turn it off under More, "Size pill on bra listings".

Private by design
- Your measurements stay on your device. There's no account and no sign-in.
- No tracking, no ads, no affiliate links. Nothing is sent to Measured Size.
- It reads a page only when you click its icon. On a few stores that load stock and size charts before you can click, a small part waits on the page to catch them.
- Delete everything it saved at any time, from "Edit measurements".

Found a wrong size?
"Report a wrong size" opens an email in your own mail program with the listing's address, the size shown and your browser's name. Your measurements go in only if you tick the box, and nothing is sent until you send it.
