Studio Ruler Pro | Pattern Drafting & Quilting Ruler

Professional Precision for Pattern Drafting, Quilting, and Custom Fit Work

The Studio Ruler Pro is the precision drafting ruler designed for makers who need accuracy they can trust. Trusted by pattern makers, quilters, and sewing instructors worldwide.

Formerly known as the Line Drafter, this redesigned 24" x 6" clear acrylic ruler brings greater control, visibility, and confidence to pattern drafting, fitting adjustments, quilting, and garment design. Whether you are drawing long straight lines, checking grainlines, squaring pattern pieces, adding seam allowances, or making careful fit corrections, the Studio Ruler Pro helps you work with the clarity and precision that professional results require.

When your measurements are off, your pattern is off. And when your pattern is off, the fit, balance, and finished garment can suffer. The Studio Ruler Pro helps remove the guesswork so you can draft, adjust, and measure with greater confidence from the very beginning.

Key Benefits

• 24" x 6" clear acrylic ruler for excellent visibility over patterns, fabric, and drafting paper

• Ergonomic handle for comfortable control when drawing, measuring, and repositioning

• Ideal for drawing long straight lines, checking grainlines, and squaring pattern pieces
• Helpful for pattern adjustments, sloper work, seam allowances, hems, and design changes

Built for Quilters

The Studio Ruler Pro's 15°, 30°, and 60° angle markings make it a versatile tool for quilters working with geometric blocks, half-square triangles, flying geese, and mitered borders. Use it to square up blocks, align quilt borders, cut accurate strips, and check angles with confidence — all with a single ruler that's long enough to span larger quilt sections without repositioning.

Why It Belongs in Your Studio

Accurate work begins with accurate tools. The Studio Ruler Pro gives you the length, stability, and visibility needed for confident drafting and measuring, without the awkward slipping or short ruler repositioning that can lead to uneven lines and inaccurate adjustments.

Its 24" length makes it especially useful for larger pattern pieces and quilt layouts, while the 6" width gives you a practical measuring surface for common adjustments. The clear acrylic allows you to see the work beneath the ruler, and the refined markings help you place lines exactly where they need to go.
