Fixed Width: Every character (from an 'i' to a 'W') occupies the same amount of space.
Note: In u8x8 , positions are based on the character grid (e.g., column 0–15, row 0–7 for a 128x64 display), not pixels. u8x8 fonts

In practice, U8x8 mode is significantly faster for text-only displays than U8g2 page mode, making it the preferred choice for applications where text needs to be refreshed frequently or where every CPU cycle counts. For projects with extremely limited RAM—such as those running on ATtiny microcontrollers or Arduino Pro Minis—U8x8‘s minimal memory requirement often makes the difference between a functional project and one that simply won‘t fit.
