The Cuup Size Chart, Interactive

Cuup built its identity on running a wider chart than fashion brands usually bother with (A to H, 30 to 44) in unlined, wire-framed styles where exact size matters more, not less.

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

Reading it

How Cuup sizing reads

Cuup’s chart reads band-then-cup in inches and US letters: the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation.

How Cuup runs

BandBands run true to size: start with your measured band on the loosest hook.
CupCups grade true to the measured difference.
Wire & strapsWires run narrow: good for projected, narrow-root shapes; wide roots may find them digging at the side. Straps: Slim, adjustable.
Quirk 1Wires run narrow; wide-root shapes may prefer the Scoop
Quirk 2Unlined styles show shape: order the silhouette for your shape, not just the size
Quirk 3No padding: the cup letter is the volume you get

Honest edges

Where this chart ends

Past H or 44, Panache and Elomi continue in UK letters. And if a symptom (riding band, gaping cup, poking wire) sent you size-hunting, the fix guides decode it before you spend anything.
