We give asymptotically sharp upper bounds for the Khovanov width and the dealternation number of positive braid links, in terms of their crossing number. The same braid-theoretic technique, combined with Ozsváth, Stipsicz, and Szabó’s Upsilon invariant, allows us to determine the exact cobordism distance between torus knots with braid index two and six.
