KiCad "Text height out of range": silkscreen text too small

KiCad design rule check (PCB) message: Text height out of range (text_height in kicad-cli reports).

What it means

A text item is smaller than the minimum text height in your rules. Text below what the fab can print comes out as a smudge. Resize it, usually all reference designators at once.

Common causes

  • Small default text sizes in footprints.
  • Text shrunk to fit a dense board.

How to fix it

  1. Use Edit → Edit Text & Graphic Properties to set height and thickness on all references at once.

Where the setting lives

Board Setup → Design Rules → Constraints → Text → Minimum text height and thickness.

What fabs need

JLCPCB lists 1.0 mm minimum silkscreen text height and PCBWay 0.8 mm, with a 0.15 mm minimum line width at both.
