Acrylic Quilting Rulers

Clear acrylic quilting rulers in the most-used patchwork sizes, with markings checked for accuracy before dispatch. A ruler that reads a quarter-inch off at one end creates compounding errors across a full quilt block — accuracy at this stage sets up the rest of the project.

A quilting ruler does one job: hold a straight edge and read a true measurement. When it does that job reliably, every cut that follows is consistent. When it does not, the error compounds across every block in the quilt. Each ruler in stock here is checked against a reference standard before it goes into an order.

Sizes and markings available

Rulers are stocked in the sizes most commonly needed for patchwork: a 6 by 24 inch strip ruler for long cuts, a 6 by 12 inch half-ruler for shorter strips and borders, a 6.5 inch square for half-square triangles, and a 12.5 inch square for blocks. Each ruler is marked in eighths of an inch with degree lines at 30, 45, and 60 degrees. The acrylic is 3mm thick throughout for a consistent grip against the rotary cutter blade.
  • 6 by 24 inch strip ruler for long cuts along fabric selvedge and border strips
  • 6 by 12 inch ruler for shorter strips, sashing cuts, and individual block borders
  • 6.5 and 12.5 inch square rulers for block trimming and half-square triangle units

Caring for an acrylic ruler

Acrylic rulers stay accurate longer when stored flat or hung vertically, away from direct heat. A warped ruler reads inaccurately within a short period. Clean the surface with a damp cloth rather than solvent-based cleaners, which cloud the markings. Any ruler that arrives with a crack or clouded print area is a defect and should be reported through the contact page within the 30-day window.
