It's tricky to give a precise answer to "how wide is the Milky Way" because it's not a perfectly flat disk. It has a central bulge and spiral arms that extend out.

Here are some estimations based on different ways of measuring it:

* Diameter of the galactic disk: 100,000 light-years (this is the most common measurement used)

* Diameter of the galactic halo: 200,000-250,000 light-years

* Width of the Milky Way at our location: About 1,000 light-years

So, the answer depends on how you define "wide". The diameter of the galactic disk is often cited as the "width", but the halo extends much further.

It's also important to note that these are estimates, and scientists are still working on refining our understanding of the Milky Way's size and structure.
