How to install fonts on Kindle Fire?

Question

I want to install another non-market fonts on my Kindle Fire. How can I do that?

Answer 1

Before installing fonts you need to make sure that those fonts meet the minimum requirements, such as:

1. The format used is TrueType or OpenType.
2. You need to have 4 variants of the files: regular, bold, bold italic, italic
3. The file structure should look like this: [name]-Regular.ttf , [name]-Bold.ttf , [name]-Italic.ttf, [name]-BoldItalic.ttf

After you make sure they meet these requirements you need to take the following steps in order to use your custom fonts:

1. Connect the Kindle to your PC;
2. Use the computer and browse the content of the Kindle and create a folder in the root of the drive : fonts;
3. Copy your files in that folder, following the structure given above;
4. Start Calibre and go to Kindle Configuration > Modify Kindle Settings;
5. From the Font Family, choose the fonts you need;
6. Save the settings and wait for the device to reboot.

If you can't open a book, then the fonts installed are not compatible with the device and software and you should look for another version or other fonts.
