What to know about Maidenform labels
Maidenform labels its band-and-cup bras in US sizes. In October 2026 its online store listed 48 bras, filtered by band size, 32 to 42, and by cup size: A, B, C, D and DD. No DDD or larger cup was listed.
Other Maidenform bras and bralettes are sold in letter sizes (S to 2XL) or in combined sizes such as M/DD and L/DD; those are not band-and-cup labels and are not in these tables. For a size, the brand's website has a Bra Guide quiz of four questions.
Maidenform's add-a-size push-up bras are labelled like its other bras, with a band and a cup: the extra volume comes from the padding, not from a different size on the label.
How US sizes work
A US size is a band number and a cup letter. The band is an inch-based label (30, 32, 34…) shared with UK sizes. After D, most US brands go DD, DDD, G, H, I, J (some write DDDD for G, and a US G is a UK F), where UK cups go DD, E, F, FF, G, GG, H, HH, J. EU and French sizes number the band differently: a US 34 band is 75 in EU sizes and 90 in French sizes.
The Maidenform size range
According to the size filter of Maidenform's online store (maidenform.com, October 2026), Maidenform bras come in bands 32–42 (US) with cups up to DD. The tables start at cup A. A given style can come in fewer sizes: check its product page.

What is the Maidenform bra size range?
According to Maidenform's online store (maidenform.com, October 2026), the Maidenform range covers bands 32–42 (EU 70–95) and cups up to DD (EU E). The tables start at cup A. A given style can come in fewer sizes: check its product page.
What is a Maidenform 34B in other sizes?
34B (US) means band 34, an underbust of about 72.5–77.5 cm, with cup B, a bust about 11–14 cm larger than the underbust. In other systems it is EU 75B, FR 90B, UK 34B and JP B75. It is within the Maidenform range given on this page.
How do Maidenform bra sizes convert to European sizes?
Maidenform uses US sizes. Converting to EU sizes: the band number changes (32 → 70, 34 → 75, 36 → 80); cups DD → E, the other letters unchanged. For example, 34DD becomes 75E.
Is there a Maidenform bra size calculator?
Maidenform's website has a Bra Guide, a quiz of four questions. To start from a tape measure, measure your underbust and your bust: the Cherry Size calculator turns the two numbers into a size estimate in US sizes and the other main systems, and the tables above give the US label to look for at Maidenform.
Do Maidenform add-a-size bras change your bra size?
No: an add-a-size push-up bra is sold in the same band-and-cup sizes as the brand's other bras, from the same 32–42 bands and A–DD cups. The padding adds volume to the look; the size on the label is still your band and cup.
Is my Maidenform size the same as at other brands?
With the same measurements, the size that fits can change from brand to brand and from style to style, and the tables on this page convert labels only: they cannot show that difference. The Cherry Size app takes two measurements, underbust and bust, and tells you the size to try at Maidenform.
