Get quoteThe 30cm Triangle Ruler Set Professional from COCAI is designed for architects, engineers, and professional illustrators working on A1 and A2 drawing boards. The 30° right-angle ruler measures 27 cm × 16 cm, and the 45° isosceles ruler measures 26 cm × 18 cm. Made from high-clarity transparent acrylic, both rulers feature precise millimetre and centimetre graduations.
The larger footprint of the 30cm Triangle Ruler Set Professional reduces the need for repositioning when ruling long structural or diagonal lines, significantly improving drawing speed and accuracy on large sheets.
The 30cm Triangle Ruler Set Professional is used in architectural design, civil engineering drafting, product design, and interior layout planning, as well as large-format picture-frame mat design.
30° triangle: 27 cm × 16 cm. 45° triangle: 26 cm × 18 cm.
Smaller option: 25cm Triangle Ruler Set. Larger option: 35cm Triangle Ruler Set. External resource: ISO Technical Drawing Standards.
