The Creative Grids® 15.5" x 15.5" Square Quilt Ruler (CGR15) is the ultimate heavy-duty, large-format template designed for squaring up massive quilt blocks, trimming t-shirt quilts, and managing wide fabric cuts. Engineered with flawless precision from premium-grade acrylic, this extra-large square ruler provides maximum surface area stability while maintaining the signature edge-to-edge accuracy that professional quilters demand.
Key Features
-
Exclusive Non-Slip Gripper Tech: Features the patented embedded gripper rings on the back side that lock securely onto your fabric under cutting pressure, yet slide freely when lifted to adjust positions.
-
High-Contrast Dual Markings: Crisp black and white dashed grid lines guarantee effortless readability on dark, light, and busy patterned textiles alike.
-
Diagonal 45-Degree Orientation Line: Features a precise, continuous corner-to-corner diagonal line designed for squaring up half-square triangles and centering blocks perfectly.
-
Expansive 15.5" x 15.5" Grid: Oversized measurement surface makes it simple to manage standard 12-inch and 15-inch finished blocks without needing to stack multiple tools.
-
Laser-Cut Acrylic Edge Tracking: Extra-thick, crystal-clear acrylic provides a durable, smooth path for rotary cutters, protecting your blades from premature nicks.
Why Customers Love This Ruler
When working with standard 12.5-inch or larger blocks, smaller rulers force you to slide your tool across multiple setups, which inevitably introduces minor measurement drift. The CGR15 completely solves this layout issue by covering the entire block under a single sheet of rock-solid, non-slip acrylic. It stops fabric shifting completely, giving you clean, flat-set trims and saving expensive yards of fabric from ruinous miscuts.

Frequently Asked Questions
Q: Why is this ruler 15.5 inches instead of exactly 15 inches? A: The extra half-inch is purposefully engineered to include your 1/4-inch seam allowances on all sides. This allows you to square up a raw block to 15.5 inches so it finishes at exactly 15 inches once sewn into your quilt top.
Q: Can I use this large ruler with small 18mm or 28mm rotary cutters? A: While it is compatible with all rotary cutter sizes, its extra-long cutting edges track best when paired with standard 45mm or 60mm rotary cutters for smooth, continuous cuts.
Q: Does it include markings for common fractions? A: Yes. The ruler features comprehensive 1-inch grids with clearly visible 1/8-inch, 1/4-inch, and 1/2-inch markings running consistently along the entire outer edge structure.
