Is It Reasonable To Keep The House at 435 Members?

[Bleeding heart conservative, HTMLdon]

Does anyone know how many physical seats there are (or could be fit in) the current chamber. 

I don't think a chamber of 600 or 700 members would work that well, but even a slight increase of 50 or 60 members would help.   I strongly support whatever number of increase would net Tennessee a 10th Congressional district  

At some point in our lifetimes each congressman could represent a million people or more - which is way outside the bounds of what our founding fathers envisioned.
