## Long description

Triangular Scale Ruler Linex 313 is a three-sided measuring ruler printed with six common scales: 1:2.5, 1:5, 1:10, 1:20, 1:50 and 1:100. The triangular profile provides stable placement on drawing surfaces and clear, separated scale edges for precise reading. Made for scaled drawing, technical sketches and model work, this Linex ruler supports conversion between drawn dimensions and real-world measurements and fits standard drawing workflows used by architects, engineers, students and hobbyists.
Advantages
The triangular shape ensures the ruler stays steady while drawing and prevents accidental rolling. Distinct, well-spaced scale graduations reduce reading errors and speed up measurement tasks. Compact and lightweight, the ruler is easy to carry in a drawing case or backpack and can be used on flat surfaces without supplementary tools. Durable printing resists fading under normal use, ensuring long-term legibility of the scales.
Suitable for
 Architectural and interior design scaled plans
 Engineering technical sketches and detail drawings
 Model building and scale modelling
 School and university drafting classes
 On-site quick measurements and sketching
Key specifications
 Profile: triangular three-sided ruler for stable placement
 Scales included: 1:2.5, 1:5, 1:10, 1:20, 1:50, 1:100
 Graduation type: printed scale markings for direct reading
 Material: lightweight rigid material suitable for drawing use
 Length: standard drafting ruler length suitable for detailed work
How to use
Place the triangular ruler on the drawing surface with the scale that matches the drawing ratio facing up. Align the ruler edge with the drawing reference line or point and read off measurements directly from the chosen scale. For drawing parallel lines or transferring measurements, use the stable triangular edge as a guide or combine with a pencil and set square. When switching scales, rotate the ruler to the appropriate face to maintain consistent conversion between the drawn size and the real-world dimension.
Usage recommendations
Handle the ruler on a clean, flat surface to maintain accurate readings; avoid bending or placing heavy objects on it. Keep the printed scales free from ink and adhesive residues to preserve legibility. For precise technical work, pair the triangular scale ruler with a mechanical pencil and a straightedge or parallel bar.
