You can increase the size of any standard console window in Windows, including Vim.
- Open the system menu by clicking the icon in the upper-left corner
of the window (to the left of the window title) or pressing
- Select the Properties menu item.
- In the Properties dialog, select the Layout tab.
- Adjust the Screen Buffer Size and Window Size.
In general, to widen the window, I adjust the Window Size Width. To make it less wide, I adjust the Screen Buffer Size Width. Editing in this way will prevent you from getting a horizontal scroll bar or having to edit both the values. For normal console apps I let the Screen Buffer Size be larger than the Window Size height to support scrolling vertically to see history, but that doesn’t apply to Vim, so you could use the same method above when changing the height.
The keyboard shortcut Alt+Enter can also be used to go into full-screen mode. This is also a standard Windows console feature, not Vim-specific.
