The Stack Layout
------------------
This is the simplest layout it displays a single window using all available
space, other windows are hidden behind it. It has no options::
enabled_layouts stack
The Tall Layout
------------------
Displays one (or optionally more) full height windows on the left half of the
screen. Remaining windows are tiled vertically on the right half of the screen.
There are options to control how the screen is split horizontally ``bias``
(an integer between ``10`` and ``90``) and options to control how many
full-height windows there are ``full_size`` (a positive integer). The syntax
for the options is shown below::
enabled_layouts tall:bias=50;full_size=1

screen. Remaining windows are tiled horizontally on the bottom half of the screen.
There are options to control how the screen is split vertically ``bias``
(an integer between ``10`` and ``90``) and options to control how many

.. _splits_layout:
The Splits Layout
--------------------
This is the most flexible layout. You can create any arrangement of windows
by splitting exiting windows repeatedly. To best use this layout you should
define a few extra keybindings in :file:`kitty.conf`::
map F5 launch --location=hsplit
map F6 launch --location=vsplit
map F7 layout_action rotate
map shift+up move_window up
map shift+left move_window left
map shift+right move_window right
map shift+down move_window down
map ctrl+left neighboring_window left
map ctrl+right neighboring_window right
map ctrl+up neighboring_window up
map ctrl+down neighboring_window down
Now you can create horizontal and vertical splits by using :kbd:`F5` and
:kbd:`F6`. You can move them around using :kbd:`shift+arrow keys`
and you can move focus to neighboring windows using :kbd:`ctrl+arrow keys`.
And you can switch an existing split from horizontal to vertical and vice versa
using :kbd:`F7`. Finally, windows can be resized using :ref:`window_resizing`.
This layout takes one option, ``split_axis`` that control if new windows
are placed into vertical or horizontal splits, by default::
enabled_layouts splits:split_axis=horizontal

.. _window_resizing:
Resizing windows
------------------
You can resize windows inside layouts. Press :sc:`start_resizing_window` (also
:kbd:`⌘+r` on macOS) to enter resizing mode and follow the on-screen
instructions. In a given window layout only some operations may be possible
for a particular window. For example, in the Tall layout you can make the first
window wider/narrower, but not taller/shorter. Note that what you are resizing
is actually not a window, but a row/column in the layout, all windows in that
row/column will be resized.
You can also define shortcuts in :file:`kitty.conf` to make the active window You can also define shortcuts in :file:`kitty.conf` to make the active window
wider, narrower, taller, or shorter by mapping to the ``resize_window`` wider, narrower, taller, or shorter by mapping to the ``resize_window``
