I searched and searched for the answer to the following question: «How do I change the font size in grub2?» It seems that no one on the entire Internet knew!

Well, I did a lot of digging into the grub2 documentation and the scripts bundled with Ubuntu and I finally have the answer!

1. Pick a font you want to use for your menu. I recommend a nice easy-to-read monospace font such as DejaVu Sans Mono (it's in the example below).
2. Convert the font to grub2's format using the grub-mkfont command, taking the extra step of setting the font size:

sudo grub-mkfont --output=/boot/grub/DejaVuSansMono.pf2 \
--size=24 /usr/share/fonts/truetype/ttf-dejavu/DejaVuSansMono.ttf

3. GRUB_FONT=/boot/grub/DejaVuSansMono.pf2

GRUB_FONT=/boot/grub/DejaVuSansMono.pf2

4.

sudo update-grub

FYI: I believe the "--size=" indicates point size but I'm not entirely sure (the documentation doesn't say). If it is based on the point scale I don't believe it is taking dpi into account since I tried "--size=72" on a 120dpi display and letters were only about half an inch tall (72 points is precisely one inch).

Hello All,
Here is small note, how to allow specific IP addresses to be accessed to your website by using .htaccess,
you may need it while maintenance website.
By assuming your hoster allows using .htaccess
all of you need it is create file named .htaccess
copy paste the code bellow (note some servers want the file be utf-8 encoded otherwise you will get 500 error)
replacing to your actual IPs.

        RewriteEngine on
	RewriteCond %{REMOTE_HOST} !^192\.168\.  #any ip from 192.168.0.0 to 192.168.255.255
	RewriteCond %{REMOTE_HOST} !^192\.190\.1\.86 #just some IP that will be allowed too
	RewriteCond %{REQUEST_URI} /.*$ 
	RewriteCond %{REQUEST_URI} !/maintenance\.html$ #users that aren't allowed will see this page
	RewriteCond %{REQUEST_URI} !(css|png|jpg)$ # if maintenance.html consists images, you have to allow them either.
	RewriteRule .* maintenance.html [R=301,L]

Also you can block users by IP, by changing a little the rules above.
