TS 10841

TS 10841 is the standard for the lettering characteristics used in technical drawings. In this field, lettering is essential for making drawings readable, consistent, and technically unambiguous, so that titles, dimensions, notes, and other annotations work as part of a controlled drawing language. This standard covers the characteristics of lettering currently used in technical drawings; it addresses the form of the lettering itself rather than a specific software tool, production process, or drawing discipline.

The role of lettering in technical drawing

In technical drawing, lettering is not decorative: it carries the information that supports the geometry. Proportions of letters and numerals, line thickness, spacing, and overall arrangement all affect legibility and consistency, especially when drawings are reproduced, copied, or shared across different teams. Good lettering practice helps prevent misreading and keeps technical documentation uniform.

What this standard focuses on

The scope of TS 10841 is the characteristics of lettering used in technical drawings. In practical terms, it provides a common technical framework for how drawing text should appear and be organised. Standards of this kind help different organisations produce drawings that are easier to interpret and compare, while supporting disciplined documentation. In general technical context, lettering standards create a shared reference for letter and numeral forms used by manual, template-based, or drafting-based methods.

This record was adopted from ISO 3098-1:1974 and is now withdrawn. TS 10841 therefore represents a historical reference point for lettering practice in technical drawing and its visual conventions.
