It seems you're asking about EKLH25 fonts, but this specific identifier is not a standard or widely recognized font family name (like Arial, Times New Roman, or Helvetica).
Here’s what’s likely happening, along with some genuinely interesting content about related topics you might find valuable. eklh25 fonts
3. PCB and Schematic Design
In electronics CAD (e.g., Altium, KiCad, Eagle), component designators like "R25" and "C100" need to remain legible when zoomed out or printed at A3 size. EKLH25's open counters prevent ink bleed. It seems you're asking about EKLH25 fonts, but
Best Practices for Legible Technical Drawings Using EKLH25
Minimum text height: Even though H25 implies 2.5mm, on A1 paper at 1:100, use at least 3.0mm for main dimensions. Reserve 2.5mm for secondary notes.
Contrast: On PDF plots, set text color to pure black (0,0,0) even if your drawing uses color layers. EKLH25's thin strokes need maximum luminance contrast.
Spacing for decimal points: Because the font is monospaced, a decimal point takes a full character width. Consider using a tab stop of 0.5x standard width if you align numbers.
Avoid all-caps for long sentences: EKLH25 lacks descenders, so all-caps paragraphs feel dense. Use sentence case or mixed case for notes longer than 10 words.
3. Interesting font topics you might actually enjoy
Since EKLH25 is obscure, here are three fascinating font-related subjects you may find even better:
Variable Fonts – One font file acts like hundreds. You can smoothly adjust weight, width, slant, and even optical size (e.g., 12pt vs 72pt). Google Fonts now supports them.
Fonts in space – The NASA Worm (1975) and DIN 1451 (German road sign font) are used on rockets. The Hubble Space Telescope uses a custom font called "Hubble" for its control panels.
The smallest readable font – Bell Labs created Bell Centennial (1978) for phone books. It has "ink traps" (tiny gaps) so when ink spread on cheap paper, letters became solid and readable at 4pt size.
