The PerfectFit Tee Ruler Set includes six guides designed to assist with aligning designs on T-shirts of various sizes, from infant to adult. Made of durable PVC, each ruler features engraved sizing charts that won’t fade or peel over time. The set offers precise measurement for both front and back placements, ensuring consistent alignment for graphic designs, whether hand-drawn or applied via heat transfer, sublimation, screen printing, or vinyl pressing. The rulers are portable and easy to store, with options in two colors—parent and white—to cover all neck areas for accurate measurement. Included are four different sizes—infant, toddler, youth, and adult—and a measuring tape along with 40 pear pins for secure placement. These tools simplify the process of aligning transfers, taking the guesswork out of design placement and helping achieve professional results every time.
