Why This Matters
This 5x5 pixel font offers a highly efficient and legible solution for tiny screens, making it ideal for low-power microcontrollers and compact displays. Its minimal memory footprint and consistent width simplify programming and layout design, enabling more effective use of limited hardware resources. This development is significant for advancing minimalist interfaces in embedded systems and IoT devices, where space and power are at a premium.
Key Takeaways
- The 5x5 font fits within a 6x6 grid, ensuring readability on tiny screens.
- It requires only 350 bytes of memory, suitable for low-resource microcontrollers.
- Constant width simplifies programming and layout safety in embedded applications.
5x5 Pixel font for tiny screens

All characters fit within a 5 pixel square, and are safe to draw on a 6x6 grid. The design is based off of lcamtuf's 5x6 font-inline.h, which is itself inspired by the ZX Spectrum's 8x8 font.
5x5 is the smallest size that doesn't compromise legibility:
2x2 : Impossible.
: Impossible. 3x3 : Technically possible, but unreadable.
: Technically possible, but unreadable. 4x4 : Not enough to draw "E", "M" or "W" properly.
: Not enough to draw "E", "M" or "W" properly. 5x5: This font.
Five by five is actually big enough to draw most lowercase letters one pixel smaller, making them visually distinct from uppercase.
