Twelve-inch T-squares handle desktop-scale work where full-size drafting tools become unwieldy. This Westcott Junior model combines clear acrylic construction with dual calibration, sixteenth-inch increments on one edge, millimeters on the other, giving you measurement flexibility without switching tools mid-project. The transparency lets you align elements beneath the blade while maintaining clear sight lines to your layout.

Fixed head construction eliminates the adjustment wobble that plagues cheaper squares, maintaining perpendicular accuracy through repeated use. Clear plastic reveals your work surface completely, essential when positioning elements in scrapbook layouts or aligning graphic components where you need to see everything simultaneously. The compact twelve-inch length fits comfortably on standard work surfaces without the overhang that makes larger squares awkward for smaller projects.

Scrapbookers use these for precise photo placement and border alignment. Graphic designers rely on them for quick mockups and thumbnail sketches. Office work, craft projects, small technical drawings, any application where you need reliable right angles and accurate measurements in a manageable size. Available in two sizes to match your typical project scale.
