The Calvin Klein Size Chart, Interactive
Calvin Klein's numbered chart is one of the narrowest on this site (A to DD on 30 to 38) because the brand's center of gravity is alpha-sized bralettes. Know which line you're buying before you trust either grid.

Same published math as the calculator (snug measure, no +4) then translated into Calvin Klein’s native notation and checked against the real chart above, which lights up your cell.
How Calvin Klein sizing reads
Calvin Klein’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.
The alpha wrinkle: Bralettes and most fashion styles run alpha (XS–XL); the numbered chart here covers underwire lines. Alpha CK sizes for the band first: the cup accommodation in each letter is generous but unlabeled.

Where this chart ends
