ISO Lettering templates, designed for use with technical pens and pencils, and to suit ISO paper sizes, produce lettering characters to an international standard. The stroke thickness is related to the character height (for example, 2.5 mm high characters would have a stroke thickness - pen nib size - of 0.25 mm, 3.5 would use a 0.35 mm pen and ...
