Westcott W-25 1 x 12" Graph Ruler Transparent

The Westcott W-25 is a 12-inch transparent graph ruler designed for drafting, drawing, and precision layout work. Its clear plastic body allows you to see your work underneath the ruler as you measure and draw lines, reducing guesswork when aligning to existing elements on a page. The markings are printed in red and calibrated in eighths of an inch, providing a clear visual contrast that is easy to read on white paper, graph paper, and other common surfaces.

A standout feature of this ruler is its zero-centering scale, which places the zero mark at the center rather than at one end. This is particularly handy for tasks like centering text or graphic elements, measuring symmetrical distances, or quickly finding the midpoint of a line. At just one inch wide and made from lightweight plastic, the W-25 is easy to store and transport, making it a practical everyday tool for students, architects, and designers who need reliable fractional-inch measurements at the drafting table.
