Meet the Concept 30cm Triangular Scale Ruler — the essential precision tool for architects, engineers, designers, and students who demand accuracy in every line they draw.

Whether you're producing technical drawings, architectural plans, or engineering schematics, scaling by hand can be a timeconsuming and errorprone challenge. This triangular scale ruler eliminates the guesswork, letting you work with confidence and speed across a wide range of standard scales:

• 1:20 — perfect for detailed room layouts and interior design plans
• 1:25 — ideal for furniture and fixture drawings
• 1:50 — the goto scale for floor plans and site sections
• 1:75 — great for midrange architectural elevations
• 1:100 — a standard for building plans and structural drawings
• 1:125 — suited for larger site overviews and landscape plans

With six scales built into one compact, triangular body, there's no need to swap between multiple tools or perform mental arithmetic midproject. Simply pick up your ruler, find your scale, and get to work — it's that straightforward.

At 30cm in length, it strikes the perfect balance between portability and practicality — light enough to slip into a pencil case or portfolio, yet substantial enough for fullscale professional use. The triangular form factor keeps it stable on your desk and prevents it from rolling away, while the clearly marked graduations ensure every measurement is clean and readable at a glance.

Why settle for anything less? Whether you're a seasoned professional streamlining your workflow or a student just starting out in technical drawing, the Concept Triangular Scale Ruler is the reliable, allinone scaling solution you'll reach for every single day.
