28mm Rotary Cutter – Best for Small, Detailed Cuts

A 28mm rotary cutter is the smallest common blade size and is perfect for intricate cutting work.

This cutter is ideal for:

• small fabric pieces
• tight curves
• applique work
• detailed quilting shapes

Because the blade is smaller, it allows for greater control and precision when working with smaller patterns or delicate fabric shapes.

However, the smaller blade means it may struggle when cutting through multiple layers of thick fabric.

45mm Rotary Cutter – The Most Popular Size

The 45mm rotary cutter is by far the most widely used rotary cutter size. It is considered the standard cutter for most quilting and sewing projects.

A 45mm cutter is great for:

• cutting cotton fabric
• quilting strips
• general sewing projects
• cutting through multiple layers

Most quilting rulers and cutting mats are designed with the 45mm blade in mind, which makes it the most versatile rotary cutter size for everyday sewing.

If you are only going to own one rotary cutter, the 45mm blade is usually the best choice.

60mm Rotary Cutter – Best for Thick Fabric & Long Cuts

A 60mm rotary cutter has a larger blade designed for cutting through thicker materials or multiple layers of fabric.

This cutter works best for:

• cutting batting
• thick fabric
• large quilting projects
• long straight cuts

Because of the larger blade diameter, it requires less pressure when cutting through heavy materials.

However, it is not as precise for small detail work compared to smaller cutters.

Which Rotary Cutter Size Should You Buy?

Most sewists eventually own more than one rotary cutter size because each has its own purpose.

If you are just starting out, the 45mm rotary cutter is the most versatile option.

For detailed quilting work or applique, adding a 28mm cutter can give you more control.

For heavy fabrics and large quilting cuts, the 60mm cutter provides more cutting power.
