How to change subdivisions after adding a grid I'm following this tutorial, when I use Add > Mesh > grid and then scale it, I get a grid with 9x9 squares:



To make the maze, I want the grid to have more squares (15x15 for e.g) however, no mater how big I scale it it remains 9x9 squares.

Is there a way to control the number of squares this grid has?
Immediately after adding the grid (See here for details as to why it has to be immediate) you can access various options at the bottom of the 3D toolbar (where it says Toggle Editmode in your screenshot) such as the x and y subdivisions:



You can also access these options (again, immediately after adding the grid) by pressing F6.

So you should:


Add the grid.
Increase x and y subdivisions as desired.
Then scale the grid up as much as you want.
