Which settlements allow the largest number of triangles and draw size?

I am wondering which settlements have the biggest item size to build in. Since this question determines that the size is calculated in polygons, I'm wondering if this amount is the same for every settlement or not?

In the answer it is said:

The size limit and current size used are actually attributes against the workbench in the settlement itself and differ between settlements.

I would still like to know what that size is for some of the bigger settlements to see how much difference there is between them. I am on Xbox, so I cannot use console commands myself to check anything.

Just to clarify: I am not talking about the size of the area itself. I am talking about the polygon count for the size bar that shows in the workshop mode while building things.

Basic Overview of Settlement Build Limits, Triangles, and Draws –Steam Discussions

I put this together because I could not find something similar and it took me a while learn this. I hope it helps someone.

Triangles: Every object in the game is made from a mesh of connected triangles. When the computer needs to create objects it uses ".nif" files (a nif file contains more than just mesh information, but that is another subject). A cube must have at least two triangles per face (12 triangles minimum). A sphere will have many more triangles, depending on how smooth it needs to appear.

Individual settlements have a game-preset limit on the number of allowed triangles (settlement limits differ). The limit can be raised, but more computer resources may be needed - and every computer is different.

Draws: When the game creates one mesh from the workshop it is using one "draw". An individual nif file can have multiple meshes, so multiple draws may be used.

Individual settlements have a game-preset limit on the number of allowed draws (settlement limits differ). The limit can be raised, but more computer resources may be needed - and every computer is different.

Example: The standard concrete foundation block with wood floor from the workbench begins with a file named ShackMidFloor01Foundation.nif

One ShackMidFloor01Foundation.nif contains three meshes and therefore requires three draws The three meshes are for the concrete portion, the wood sides above the concrete, and the wood floor planks.

One ShackMidFloor01Foundation.nif contains 96 triangles. 36 are for the concrete portion, 48 are for the wood sides above the concrete, and 12 are for the wood floor planks.

The settlement of Sanctuary is setup to allow 3,000,000 triangles. So, does that mean you can theoretically build 31,250 ShackMidFloor01Foundation.nifs? NO! But why? You see, the workbench in the settlement of Sanctuary is also setup to cease new construction at 3,000 draws - and each ShackMidFloor01Foundation.nif uses three draws. So, does that mean you can theoretically only add 1,000 ShackMidFloor01Foundation.nifs - even though you are well below the triangle limit? YES!

Q & A

Q: So, that settlement size bar in the upper right corner that gets bigger it a function of the draw count, not the triangle count?
A: YES!

Q: The settlement size bar gets smaller when I scrap settlement items that are not created in the workbench. It seems like a player could get around the draw count by just traveling around outside the settlement and collecting a bunch of junk, dropping the junk from the Pip-Boy onto the ground of the settlement, and scrap it. Since the "outside" junk can be scrapped - it must be related to the workbench, even though it was not originally built in the settlement. Can I reduce a settlement draw count for scrapping something I bring in from outside the settlement without using a mod?
A: YES!
