The Marie Jo Size Chart, Interactive

Marie Jo charts Belgian-made European sizing (bands 65 to 95, cups A to F in continental letters) with much of its commerce flowing through UK retailers who relabel every size in inches.

The native chart

Every Marie Jo size: tap for conversions

UK stockists list these exact sizes as 30–42 bands with UK letters; the EU grid here is the factory original.

Same published math as the calculator (snug measure, no +4) then translated into Marie Jo’s native notation and checked against the real chart above, which lights up your cell.

Reading it

How Marie Jo sizing reads

Marie Jo reads band-then-cup on European centimeters. Because so much of the brand sells through UK shops, the same bra often appears twice online (once as 75C, once as 34C) and above D the letters stop agreeing: EU E is UK DD. Convert by position, and this grid is the position of record.
