6x14h font (often referred to as SystemFont6x14h ) is a specific fixed-width font commonly used in the DMD (Dot Matrix Display) library
for Arduino. This font is typically part of a larger library package rather than a standalone system font. 1. Download the Font Since this font is usually bundled with the DMD library
, the best way to get it is by downloading the entire repository from GitHub: DMD Library GitHub repository Click the green button and select "Download ZIP" Extract the ZIP file on your computer. Arduino Forum 2. Install the Font into the Arduino IDE To use the
font in your projects, you must place the library in the correct directory: Locate your Arduino Sketchbook folder (usually found in Documents > Arduino Copy the extracted folder into this Verify the font file: Inside the folder, ensure there is a file named SystemFont6x14h.h Restart the Arduino IDE to allow it to recognize the new library and font files. 3. How to Use it in a Sketch
Once installed, you must include both the DMD library and the specific font file in your code:
The 6x14h font is a specialized bitmap font commonly used in Linux, Unix-like operating systems, and for low-resolution hardware displays like monochrome LCDs or OLEDs. This font's name refers to its fixed dimensions: a width of 6 pixels and a height of 14 pixels. Understanding the 6x14h Font Library
Unlike standard scalable fonts (like TrueType or OpenType), the 6x14h font is a bitmap font. It is constructed from a rigid grid of pixels, making it ideal for:
Terminal Emulators: Ensuring crisp, readable text at specific small sizes in command-line interfaces.
Embedded Systems: Providing lightweight typography for microcontrollers and small digital screens.
Legacy Hardware: Maintaining compatibility with older systems that rely on the .pcf or .bdf file formats. How to Download the 6x14h Library
You can typically find the 6x14h font library through several verified digital repositories:
Open Font Databases: Sites like Font Library host a variety of bitmap and open-license fonts.
GitHub Repositories: Developers often share these fonts in "Bitmap Header" format for hardware projects. Look for libraries like BMH-fonts that include standard ASCII characters for monochrome displays.
Linux Package Managers: On many distributions, these fonts are part of "xfonts" packages. You can often install them directly using commands like sudo apt-get install xfonts-base. Installation Guide
The installation method depends on your operating system and the specific file format (e.g., .ttf, .pcf, or .bdf). For Windows Users

Here’s a write-up for downloading, installing, and using a 6x14 (or 6x14h) font library — typically used in embedded systems, framebuffer consoles, and retro-style terminal applications.
1. Download the font header
Many open-source projects include font6x14h.h. Example using tinyfonts:
git clone https://github.com/robey/fonts-for-displays.git
cd fonts-for-displays
Or directly download the single header:
wget https://raw.githubusercontent.com/example/font6x14/master/font6x14h.h
Write-up: Download & Install Font 6x14h Library
For X11 (graphical terminal)
Convert BDF to PCF if needed:
bdftopcf 6x14.bdf > 6x14.pcf
gzip 6x14.pcf
sudo cp 6x14.pcf.gz /usr/share/fonts/X11/misc/
sudo mkfontdir /usr/share/fonts/X11/misc/
xset +fp /usr/share/fonts/X11/misc/
xset fp rehash
Then use in xterm, st, or urxvt:
xterm -fn -misc-fixed-medium-r-semicondensed--14-140-75-75-c-70-iso10646-1
Option 1 – Installing for Linux Console / Terminal
If you want 6x14h as a system console font (e.g., in TTY before X starts):
3. How to Verify and Use
Once installed, you must configure your terminal or text editor to use it.
On Linux: You can verify the font is installed by running:
xlsfonts | grep 6x14
You should see an output like:
-misc-fixed-medium-r-normal--14-130-75-75-c-70-iso8859-1
Configuring Terminals:
- URxvt: Add to
.Xresources:URxvt.font: -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1 - xterm: Launch with
xterm -fa '6x14'or set the font viaxterm*font: 6x14in.Xdefaults.
Configuring IDEs (VS Code / Vim): In your settings JSON, set the font family:
"editor.fontFamily": "6x14",
"editor.fontSize": 14,
"editor.fontLigatures": false
(Ensure anti-aliasing is handled correctly by the editor).
2. Add to your project
Place font6x14h.h in your include/ directory.
In your source code:
#include "font6x14h.h"
// Draw character 'A' using the 6x14 bitmap data draw_bitmap(6, 14, font6x14h['A'], x, y);
1. What is "font 6x14h"?
- 6x14 means each character is 6 pixels wide and 14 pixels tall.
- The "h" often stands for "height" or indicates a horizontal (or sometimes "hardware") variant.
- It’s a monospaced bitmap font, common in:
- Linux virtual consoles
- GRUB bootloader
- Simple framebuffer applications
- Old DOS / ANSI art environments
The font is part of the Linux consolefonts collection (like LatArCyrHeb-14, Sun12x22, etc.) or from legacy X11 bitmap fonts.
