Notes:

  1. For smaller text heights ( 2mm to 2.5 mm ) it is advisable to do a test print with the font(s) proposed as the clarity and readability does vary between fonts. Paper type also affects readability.
  2. Set standards, for example: Text above 5 mm (or 3.5 mm) height to be in Paper Space (If appropriate to your discipline, layering standards and interdisciplinary data exchange).
  3. A combination of "standard"(from drafting stencil sizes) and "full metric" would be acceptable as long as it is documented. (For differentiation purposes or clarity -See note:1.)
  4. Round up the 0.5ís to the next highest figure for ease of use.
