Ruler Donau large 19 cm, 60 lines, transparent

Large transparent Donau ruler, 19 cm long with 60 equally spaced markings designed for precise measuring and drawing in school, office and home environments. The clear plastic construction enables accurate alignment over text and drawings while the compact length fits pencil cases, notebooks and desk drawers. This ruler combines a simple graduated scale with a slim, lightweight profile for everyday measurement and basic drafting tasks.

Advantages

The transparent material provides unobstructed visibility of the surface beneath, making it easier to position the ruler precisely along lines and text. Sixty evenly spaced markings give fine resolution for short-distance measurements and simple drafting. The 19 cm length balances portability and useful measuring range, while the thin profile reduces bulk in stationery sets. The ruler is resistant to common classroom and office wear and can be used with pencils and pens without significantly obscuring the scale.

Suitable for

• Measuring and drawing straight lines in school geometry and art classes
• Everyday office measurements and quick layout checks
• Notebook and planner use for marking and spacing
• Drafting small diagrams and technical sketches

Key specifications

• Length: 19 cm
• Markings: 60 equally spaced graduation lines
• Material: transparent plastic
• Profile: slim, lightweight
• Visibility: clear surface for alignment over documents

How to use

Place the ruler on the document or drawing so the edge aligns with the points you want to join or measure. Use the visible graduation lines to read distances from the starting point; for greater accuracy, view the markings at eye level and keep the ruler steady with one hand while drawing or measuring with the other. For straight lines, hold the pencil at a consistent angle and move it along the ruler edge. Clean the surface periodically with a soft cloth to remove dust and pencil residue that could affect visibility.

Usage recommendations

Store the ruler flat or in a stationery pouch to avoid warping. Avoid exposure to high heat or solvents that can deform or cloud the plastic. For tasks requiring finer precision over longer spans, consider using a longer ruler or a metal straightedge.
