  Khovanov homology is a bigraded Z-module that categorifies the Jones
polynomial. The support of Khovanov homology lies on a finite number of slope
two lines with respect to the bigrading. The Khovanov width is essentially the
largest horizontal distance between two such lines. We show that it is possible
to generate infinite families of links with the same Khovanov width from link
diagrams satisfying certain conditions. Consequently, we compute the Khovanov
width for all closed 3-braids.
