Difference Between 45mm and 60mm Rotary Cutter : 6 Factors

Rotary cutters are a great tool to have in any sewing room. They can be used for various tasks, from cutting fabric to trimming seams. Different sizes are available, but the two most common sizes are 45mm and 60mm. You need a rotary cutter that is suitable for your project.

The 45mm rotary cutter is the most versatile. Several tasks can be completed with it. The 60mm rotary cutter is suitable for larger projects. It is a wise choice for quilters and anyone who works with large pieces of fabric at once.

So, which size should you choose? To know for sure, it’s best to find the difference between a 45mm and 60mm rotary cutter. With a little bit of guidance, you’ll be able to find the perfect rotary cutter for your needs.

What Is the Difference Between 45mm and 60mm Rotary Cutter?

Choosing a suitable rotary cutter is essential for any sewing project. The size of the rotary blade will determine how well the fabric cuts and how easy it is to maneuver. Some of the most common sizes of rotary cutters are 45mm and 60mm.

Here is a breakdown of the difference between the two:


The most significant difference between the two types of rotary cutters is their size. The 45mm cutter is smaller than the 60mm, making it easier to maneuver and control. It is also lighter, which can be important when working on a detailed project.

The 60mm cutter is more extensive and heavier, making it better for cutting through more than one layer of fabric at once. It can also be challenging to control, so it’s important to be aware before choosing this size.

Cutting Ability:

The 45mm can handle most fabric types with ease and can even cut multiple layers of thin fabric. Also, it can make tight turns and detailed cuts because it is smaller. Smaller projects or quilters may find it helpful.

60mm blades are better suited to cutting through thicker fabrics or layers of fabric at once. The larger size makes it less maneuverable, which makes it unsuitable for detailed work. 


The cost of the rotary cutter is also a factor to consider. The 45mm is typically less expensive than the 60mm, making it a good choice for those on a budget. Because the 60mm is larger and more powerful, it will usually be more expensive.

Also, the brand of the rotary cutter can affect the price. Most brands offer both 45mm and 60mm rotary cutters, so it’s important to compare prices before making a purchase. The cutter will last longer if you invest in a higher-quality one.

Ease of Use:

Using the 45mm cutter is easier because it is smaller and lighter weight. It is also less likely to cause accidental cuts. Also, the blades are easier to change on a 45mm cutter. Using the cutter for multiple projects can make this important.

The 60mm cutter can be more challenging because of its size and weight. It is also more prone to causing accidental cuts. Changing the blades is more difficult on a 60mm cutter, which can be a downside if you use it for multiple projects.

Blade Type:

Choosing a rotary cutter also involves considering the type of rotary blade. 45mm cutters can use mini and standard blades, and 60mm cutters only use standard blades. Mini blades are more effective when working with multiple layers of fabric.

The 60mm cutter can only use standard blades, so it’s not the best choice for detailed work. Multi layered fabric is easily cut through with the rotary blade. If you plan on doing a lot of sewing with thicker fabric, the 60mm cutter is a good choice.

How Do I Know Which Size Rotary Cutter I Need?

When choosing a rotary cutter, a good rule of thumb is to choose the largest size that will comfortably fit in your hand. The 45mm and 60mm are popular sizes used to cut a wide range of materials.

The size of the rotary cutter you need depends on the fabric you are cutting and the project you are working on. There are a few things you’ll need to keep in mind when deciding on the size of rotary cutter you need.

When cutting fabric, it is crucial to use the proper size rotary cutter blade for the job. If you’re only dealing with light fabrics, then a 45mm cutter should be sufficient. The 60mm cutter is needed for heavier materials such as denim or leather.

A 45mm blade is suitable for general purpose cutting and can handle multiple layers of thinner fabric. The 60mm blade performs better when slicing through thicker fabrics or layers of fabric.

Your project’s size is another factor to consider. A 45mm cutter will do just fine if you’re only cutting small pieces. But if you’re working on a larger project, then you’ll need a 60mm cutter to get the job done.

If you’re planning on cutting thicker materials or working in tight spaces, you may want to consider a smaller size. Ultimately, selecting a rotary cutter that feels comfortable and gives you the level of control you need for the task at hand is essential.

A rotary cutter is a handheld circular blade used to cut fabric. It is a popular tool among quilters and other crafters because it can make clean, straight cuts quickly and easily across multiple layers of fabric.

Rotary cutters come in various sizes, but the most common are 45mm and 60mm. The number of layers that each rotary cutter can handle will also vary depending on the fabric.

The 45mm size is perfect for most quilting cotton projects and can hold up to four to six layers of fabric, depending on the type. When you have only one rotary cutter, this is the best rotary cutter option since it performs most cutting functions efficiently.

With a 60mm blade, you can cut through six to eight layers of quilting cotton and thick fabrics like denim and leather. The size rotary cutter you need is similar to this if you are working on a project that involves a lot of cutting.

Which Size Rotary Cutter Is Best for Quilting?

Quilters need a versatile rotary cutter that can handle various thicknesses of fabric. The most popular sizes are 45mm and 60mm because they offer excellent cutting through multiple fabric layers while still maneuvering around tight curves.

When it comes to quilting rotary cutters, 45mm is the standard. All your basic quilting cuts can be made with this tool, and it’s comfortable to hold. The 60mm is also a good choice for quilting, although if you’re cutting thick layers, it’s better.

45mm is the standard size for most quilting projects, but 60mm may be necessary for cutting through thicker fabrics. Selecting a rotary cutter and selecting a size that will suit your needs will depend on the type of quilting project you will be working on.

Rotary cutter blades are one of the most important tools in a fabricator’s arsenal. They are specially designed to cut through materials quickly and efficiently, and they can be used on various projects. Your rotary cutter’s blade needs to be changed depending on how often you use it.

Although rotary cutter blades will eventually dull, as with any tool, they will eventually wear out. The blades must be replaced when this happens to ensure smooth, accurate cutting. For most fabricators, changing 40mm and 60mm rotary cutter blades are a regular part of their workflow.

Depending on the frequency of use, the blades may need to be changed as often as every week or two. By keeping a sharp set of blades on hand, fabricators can be sure that their projects will always turn out perfectly.

Do You Think There Is a Need for Both A 45mm and 60mm Rotary Cutter?

Rotary cutters of 45mm and 60mm are helpful for various projects. Each has its own advantages and disadvantages, so it’s important to choose the right one for your needs. 

Ultimately, the choice of a rotary cutter depends on the difference between 45mm and 60mm rotary cutter.  45mm cutters are suitable for cutting small pieces of fabric. If you need to cut larger pieces of fabric or multiple layers at once, then the 60mm cutter is a better choice.

So if you think you might need both sizes, then get one of each.  Having both will give you the versatility to tackle any project that comes your way. Also, get a good quality cutter to last a long time and give precise cuts.
