Staedtler Ruler Scale Triangular Din 1:100, 200, 250, 300, 400, 500 - 61 98-4BK

Staedtler Ruler Scale Triangular

The Staedtler triangular scale ruler carries six DIN-standard scales on a single three-sided instrument — 1:100, 1:200, 1:250, 1:300, 1:400, and 1:500. Each flat face of the triangular body carries two scales running in opposite directions from each end, so all six are immediately accessible without tools or adjustment. This is the standard scale set for architectural and building documentation in Australia and internationally, and the triangular form is the established format for professional and student technical drawing work where multiple scales are needed regularly.

SIX DIN SCALES ON ONE INSTRUMENT

The triangular cross-section allows six individual scales to occupy a single ruler without making any one face cluttered or difficult to read. Each scale is printed with clear graduations and numerical labelling so the correct scale can be found quickly and the reading made accurately. DIN (Deutsches Institut für Normung) is the international technical standards framework used for drafting instruments, and DIN-compliant scales are directly applicable to Australian Standards drawing practice and to the metric drawing conventions used across architecture, engineering and construction in Australia.

STANDARD SCALES FOR ARCHITECTURAL AND TECHNICAL DRAWING

The six scales on this ruler cover the core range used in building and technical documentation. 1:100 is the standard floor plan scale for most residential and small commercial work. 1:200 handles site plans and overview drawings. 1:250 and 1:300 appear in engineering and services documentation. 1:400 and 1:500 are used for larger site plans, masterplanning work and drawings where a wider area must be shown at reduced size. Having all six on one instrument means switching between drawing tasks or checking dimensions at different scales requires only a rotation of the ruler rather than reaching for a separate tool. Architecture students, drafting students and anyone working through technical drawing curricula will find this set covers the scales required for the full range of standard exercises and assessment tasks.

PRECISION INSTRUMENT FOR PROFESSIONAL AND STUDENT USE

Staedtler is a German manufacturer with a long history in precision drawing instruments, and the triangular scale ruler is produced to the standard expected of professional drafting tools — consistent graduation spacing, legible scale markings, and a form factor that sits stably on a drawing board or desk. The black (BK) marking version provides strong contrast against the ruler body for clear reading under drawing board lighting. The triangular section also makes the ruler easy to pick up from a flat surface without it rolling or sliding.
