How do I set the default font size in Vim?

Question

I am trying to configure the default settings for my GUI with Vim. I already made research on the web, but all the solutions I found and tried did not work.

Here are

Answer 1

The other answers are what you asked about, but in case it’s useful to anyone else, here’s how to set the font conditionally from the screen DPI (Windows only):

set guifont=default
if has('windows')
    "get dpi, strip out utf-16 garbage and new lines
    "system() converts 0x00 to 0x01 for 'platform independence'
    "should return something like 'PixelsPerXLogicalInch=192'
    "get the part from the = to the end of the line (eg '=192') and strip
    "the first character
    "and convert to a number
    let dpi = str2nr(strpart(matchstr(substitute(
        \system('wmic desktopmonitor get PixelsPerXLogicalInch /value'),
        \'\%x01\|\%x0a\|\%x0a\|\%xff\|\%xfe', '', 'g'),
        \'=.*$'), 1))
    if dpi > 100
        set guifont=high_dpi_font
    endif
endif

Answer 2

I cross over the same problem I put the following code in the folder ~/.gvimrc and it works.

set guifont=Monaco:h20

Answer 3

For the first one remove the spaces. Whitespace matters for the set command.

set guifont=Monaco:h20

For the second one it should be (the h specifies the height)

set guifont=Monospace:h20

My recommendation for setting the font is to do (if your version supports it)

set guifont=*

This will pop up a menu that allows you to select the font. After selecting the font, type

set guifont?

To show what the current guifont is set to. After that copy that line into your vimrc or gvimrc. If there are spaces in the font add a \ to escape the space.

set guifont=Monospace\ 20

Answer 4

Add Regular to syntax and use gfn:

set gfn= Monospace\ Regular:h13

Answer 5

Try a \<Space> before 12, like so:

:set guifont=Monospace\ 12
