Neither the Nederlander Organization nor Jujamcyn seem to have the info on their site (or at least in place where it is readily seen). The Jujamcyn site actually seems to be pretty bare bones compared to the other two.

There are so many variables to that question that it would be difficult to sort through the many details of each theatre to compare. Some theatres might have shallow wing space but might have a deep stage while others might have a shallow stage with lots of wing space. In most theatres one wing usually has more space than the other wing. Some have obstacles and some have more line sets and some have less. Some have odd configurations (the oddest being The Ambassador Theatre which is like a square inside a diamond shape).
So let me know 2 or 3 theatres you want me to list and I'll do that. The largest in stage space appears to be The Gershwin and I'll post the details below. (The Beaumont might indeed be larger but my documents do not list any auxillary spaces that might be beyond the wings or the back wall).
You can see there is a lot of information.
(Also for those that might not know, the "smoke pocket" is the channel of steel along the upstage edge of the proscenium on both sides of the stage that the fire curtain travels in. Typically 4 to 6 inches.)

I'm getting this information from a book I won on ebay. It's called "Stage Specs - A Technical Guide to Theatres" and it was published by The League of American Theatres and Producers. It's a HUGE book and it has details on not only the Broadway houses but also large houses in cities across the country. It is dated 1999 and the published price of the book at that time was $125.00. I got it for $5.00! I'm not sure they publish a printed book anymore. It appears that the database is now available online but it costs $175.00 a year to access it. Here's a sample of what I'm looking at (I've edited out phone numbers which might be private and are probably not accurate any longer anyway).

Wow... the Majestic has one of the deepest apron on Broadway! Also, a 12 foot deep orchestra pit? So looking at the attached image, it can be assumed that pit filler is used... How many rows? Also, can we assume that the draped chandler is downstage of the house curtain?
