So, we have 3 big Setting equivalence with the DMG here:
Given that, a Faerûn Gazateer of about 50 pages could give each region a good 4 pages each, with room for more general information similar to what we see in the DMG Campaigns chapter.
- 50 pages of 1 page low prep Adventures, spread across 10 regions, similar to the 5 sample Adventures in the DMG tied to the Greyhawk region
- 5 focused "mini-settings", which seem similar to the 11 page zoom in on the Free City of Greyhawk and the region around it in the Campaigns chapter
- and 50 pages in the PHB that sound like the same sort of material in the 11 page Greyhawk Gazateer covering the entire continent of the Flannaes, also in the Campaign chapter: of note here they divide the Flannaes into 5 regions of about 2 pages description each
Given that, a Faerûn Gazateer of about 50 pages could give each region a good 4 pages each, with room for more general information similar to what we see in the DMG Campaigns chapter.
