28mm vs 45mm Rotary Cutter — When to Use the Smaller Blade

The 45mm is the standard quilting rotary cutter — but the 28mm has a place in every quilter’s toolkit for tight curves, small shapes, and precision cutting that larger blades can’t handle. Here’s when you need the 28mm.

▶ Our VerdictBuy the 45mm first and use it for everything. Add the 28mm when you start doing curved applique, paper piecing shapes, or any project that requires following tight curves. Most quilters who own a 28mm reach for it only occasionally — but when they need it, nothing else works.

  • Raw-edge applique with curves
  • Paper piecing small sections

Frequently Asked Questions

Do 28mm and 45mm blades use the same blade format?

No — 28mm and 45mm blades are different sizes and are not interchangeable. Each cutter requires its own specific replacement blade. When ordering replacement blades, always match the blade size to your cutter.

Can a 28mm cut through multiple layers?

The 28mm can cut through 2–3 layers of quilting cotton cleanly, but it’s not designed for high-layer cutting. For cutting 4+ layers, use the 45mm.

What is the 28mm best for in quilting?

The 28mm excels at curved applique shapes, following paper piecing seam allowance templates, and cutting any small intricate piece where a larger blade would be too unwieldy. It’s also excellent for trimming seam allowances on curved seams.
