  We prove two results about width of words in $SL_n(\mathbb{Z})$. The first is
that, for every $n \geq 3$, there is a constant $C(n)$ such that the width of
any word in $SL_n(\mathbb{Z})$ is less than $C(n)$. The second result is that,
for any word $w$, if $n$ is big enough, the width of $w$ in $SL_n(\mathbb{Z})$
is at most 87.
