Coverstitch Machine Vs Serger Machine(Both Machine Pros And Cons)?

Most of the time, new sewers ask this question themselves, “What is the Difference Between coverstitch machine vs serger?” At first glance, both a sager machine and a coverstitch machine are the same type of machine and seem to do the same thing. 

But that is far from the reality as these two machines serve different purposes and have various features that enhance your finished product as one tends to trim down with an overlock stitch which a regular sewing machine is unable to do. The other comes with elasticity and flexibility with a cover stitch.

Now, if you are beginning sewing and stitching, all these terms can seem identical and lead to confusion regarding the difference between coverstitch machine vs serger.

But don’t worry, in this article, we’ll dive deep into the difference between serger and coverstitch machine so that you can easily pick which one is better suited for you.

What is Serger Machine?

A serger machine is a type of sewing machine that is used to create finished seams on fabric. Sergers are often used in garment construction because they can create strong, professional-looking seams.

What is a Coverstitch Machine?

A coverstitch machine is a type of sewing machine that is designed to sew a variety of fabrics. The machine is easy to operate and is less expensive than a serger. The machine can be difficult to thread and may not be able to sew certain types of fabrics. The machine may be difficult to operate for beginners. The machine may be difficult to find in stores.

What Does Do: Coverstitch vs Serger Machine

Serger machine and coverstitch machine are great choices to enhance your sewing project and stitching to the next level. 

But they are needed in entirely different fields which can’t be covered by a traditional sewing machine. If you focus on constructing knit garments, then go for serger machines, and although coverstitch machines can do knit fabric hemming, it is best to go with a serger machine.

But if you are looking for different types of stitches including topstitchs and optimal hemming, go for a coverstitch machine anytime. 

While both machines are used to finish a sewed work properly, a serger machine works on overlock stitches. In contrast, a coverstitch machine is created to provide cover stitches on layers of fabric. 

To be more precise, serger machines provide and allow you to sew a seam quickly and easily. On the other hand, coverstitch devices give hems a professional finish and grant the fabric to be stretched without harming the fabric’s core.

Serger Machine

To the rest of the world, serger machines or Overlocker machines are used to give a professional finish and refined output to seams, hems, sleeves, and other tailored items and fabrics.

Primarily focused on working with knits, a serger machine trims a material and its edges to have a smooth operation afterward. It does this by doing an overlock stitch on the inside portion of your fabric.

A serger machine comes with multiple thread cones ranging from 2 to 8, depending on which type of serger machines you are using. It also includes loppers.

But the most critical factor that makes a serger unique is the included blades for trimming the uneven edges of the fabric. This allows the machine to give you a perfect, excellent finished product that won’t be obtainable by just sewing.

So, in general, a serger machine trims and security seems so that they can’t unravel. This gives your work a professional finished output that secures the durability of the product.


  • Serger machines can sew faster than regular sewing machines.
  • Sergers can sew through multiple layers of fabric at once.
  • Sergers can create professional looking seams.
  • Sergers can cut fabric as they sew, which saves time.


  • Sergers can be more expensive than regular sewing machines.
  • Sergers can be more difficult to use than regular sewing machines.
  • Sergers can be noisy.
  • Sergers can create a lot of lint.

Coverstitch Machine

If you want perfectly finished hems on knit fabrics, going with a coverstitch machine is the best option. Going with a coverstitch machine, you can create stretchable, even, and secure seems that quickly move within the fabric.

A coverstitch machine comes with extra features like single to multiple threads or needles. The standard coverstitch machine consists of at least two lines and a looper. The significant change from a serger machine here is that a coverstitch device doesn’t have any blade trimmer or built-in thread cutter. 

The top needle or the top threads work to create the straight stitch part, and on the other end, the looper on the bottom of the reverse side makes a zigzag grid which gives the completed stitch the stretch and durability required for it to perform optimally.  

So, if we sum it all up, a coverstitch machine is primarily used for topstitching knits and the hemming process. To create a coverstitch, a coverstitch machine creates straight stitches on your fabric on the front and a zigzag grid or chain stitch on the reverse side on the looper thread, which crosses between the needle threads.


  • The coverstitch machine makes it easier to sew a variety of fabrics.
  • You can sew several layers of fabric at the same time.
  • The machine is easy to operate.
  • It is less expensive than a serger.


  • The machine can be difficult to thread.
  • The machine may not be able to sew certain types of fabrics.
  • The machine may be difficult to operate for beginners.
  • The machine may be difficult to find in stores.

Difference Between: Coverstitch Machine Vs Serger

Now that we know the basics difference, both separate machines of a serger machine or overlocker machine and a coverstitch machine. Let’s take a deep  look at what makes them different from each other.

Stitching: The first and foremost difference is the stitching process of a serger and a coverstitch machine. For a serger machine, the stitching process that it goes through is overlock stitching, meaning it sews over the raw edges one or two or sometimes three pieces of the fabric to provide hemming or stretchable seam. A serger machine can serve decorative stitch also. 

On the flip side, a coverstitch machine goes with the coverstitch stitching process, created by the two needles or threads to do two straight stitches. In contrast, the looper needle or thread zigzag on the opposite side of the fabric, which is in between the straight-line stitches. This is best if you require professional hemming in your finishing tasks.

So, for an overall decision, a serger machine stitching is preferred for constructing knit garments, and while you can use it for other purposes. A coverstitch machine is a better option than a serger if you need excellent quality in topstitching and hemming in stretchy fabrics.     

Trimming: This is one of the areas where a serger machine excels over a coverstitch machine. With its included two trimming blades, a serger machine serges the edges and trims off the unnecessary fabrics. This is something that a coverstitch machine can’t do as it doesn’t have any functions or equipment included like that.

Stitching Versatility: A serger machine’s essential function is to trim down the fabric; it isn’t a versatile machine if you want to stitch on a part that you don’t want to get trimmed off. But this problem doesn’t occur on a coverstitch machine as it doesn’t have any trimming functions, and you can be as creative as you want to be.

A point to be noted is that some new serger machines give you the option to disable trimming.

Working Space: The working space of a serger machine is relatively smaller as it has no arm features than a coverstitch machine feed dogs. This gives a coverstitch device an advantageous edge over a serger machine as you can do large projects with ease on a coverstitch machine and it sometimes comes with presser feet that makes it more versatile with its control dial.

Loopers: Serger machines have two loopers, while a coverstitch machine comes with one. This helps to lock the needles more precisely and optimally on serger machines compared to coverstitch devices.

Sewing Machine Replacement

Although it isn’t optimal, and we don’t recommend it, a coverstitch machine can serve as a sewing machine in limited functions while a serger machine doesn’t offer that luxury to begin with. And also, the output of using a coverstitch machine as a sewing machine will not provide the best results.

These are the significant differences between coverstitch machine vs serger. From this, one thing is clear that although both are labeled for giving the finishing touch on your sewed fabrics, they serve entirely different purposes and should only be picked if you want to focus on improving in that specific area of stitching and sewing.

Bottom Line: Coverstitch Machine Vs Serger
