Overview
A 12-inch triangular architect's scale ruler machined from anodized aluminum, with six color-coded scales spread across its three faces for converting blueprint distances into real dimensions.
The triangular cross-section is what separates this from a flat scale ruler: each face carries its own set of scales so a drafter can flip to the right ratio without crowding six scales onto two edges. A slightly concave underside is meant to keep the tool from smearing pencil lines as it slides across a drawing.
- 12-inch triangular aluminum body
- Six color-coded scales
- Laser-etched, non-fading markings
- Concave edge reduces smearing
Who it's for
Built for architecture and engineering students, draftsmen and anyone who reads scaled construction drawings regularly. Someone who only needs straight-line measuring is better served by a flat ruler.
Pros and cons
- Six scales across three faces
- Laser-etched markings resist wearing off
- Rigid aluminum resists warping
- Compact and lightweight for a bag
- Triangular shape has a learning curve
Performance notes
Rigid anodized aluminum resists the flex and warping that can throw off a reading, the concave face keeps the ruler slightly lifted off the page to reduce smearing, and laser-etched markings on all six scales are built to stay legible rather than rub off with handling.
