On a 128x64 OLED display, an 8x16 font only allows 16 characters per line across 4 lines. A 6x14 font increases this to 21 characters per line across 4 lines , granting you 20 additional characters of screen real estate.

Contiki, the OS for low-power IoT, historically shipped with a c64-fonts.h or similar bitmap sets. Their classic fonts/6x14.h is available in their source tree. Font 6x14.h Library Download
The Font_6x14.h file is popular because its small bitmap format consumes little flash memory. However, the total font data, combined with the rest of your program, must fit within your microcontroller's storage. For an Arduino Uno, for instance, the maximum is approximately 32KB. Careful selection of fonts helps avoid running out of memory.

The Ultimate Guide to the 6x14.h Font Library: Download, Installation, and Usage
The 6x14 font library works seamlessly across all major display controllers: SSD1306, SH1106, SSD1309 (via I2C/SPI) TFT LCDs: ST7735, ILI9341, ST7789 e-Paper: Waveshare ink displays Customizing the Font
Imagine you’re building a sleek digital clock or a custom weather station using an Arduino and a small OLED display. The default 5x7 font looks a bit blocky, and you want something taller and more legible. You go searching for a "6x14" font—6 pixels wide and 14 pixels tall—because it provides that perfect balance of clarity without hogging all your screen space.
