Eliminate the guesswork in your architectural notations and engineering drawings. The STAEDTLER Mars 974-98 creates perfectly uniform guidelines, ensuring every character you write is consistent, legible, and professional.
Engineered for Technical Mastery
Designed for architects, engineers, and students, this precise instrument translates complex spacing needs into effortless workflows. Whether you are cross-hatching a floor plan or hand-lettering a comic, this tool provides the structural reliability you require.
Define line heights from 1/16" to 2" using the rotating disk calibrated in precise 1/32" increments for total control.
High-contrast markings are etched directly into the heavy-duty transparent acrylic so they never wear off during heavy use.
Built-in columns support the Reinhardt System (3/5 and 2/3 ratios) to automatically scale lowercase letters to capitals.
Perfect for creating consistent cross-sections, brick patterns, musical staves, and slanted script guidelines at a 68° angle.
