Things to Consider

A serger can be an important machine for people who spend a lot of time sewing, and Brother has long been a name brand that professionals trust. It’s essential to know the different options and capabilities of the models available on the market, though, to make sure you purchase a machine that works for you and your needs. Not all models come with cutting blades or free arms for sewing cuffs, so potential users should learn more about different options of the Brother models.

Why should I consider Brother sergers?

One need only watch a season of Project Runway to be reminded of the capabilities of Brother machines. Brother sergers allow you to create professional, high-quality products with minimum effort. Since they’ve been providing machines for years, they also offer an extensive warranty and technical help for their products. Brother focuses on commercial sewing, for those users who either have a sewing business or for people who want to take their sewing to the next level. They pride themselves on their ability to help businesses get ahead by using their machines, but they also offer models that work well for more novice sewers or people who haven’t used a serger before. Brother has a little bit of everything for any customer.

5 Outstanding Brother Sergers - Reliable Brand for Simpler Overlocking!How to choose the best serger?

Sergers can perform a variety of tasks, everything from different stitches, finishing hems, design projects, and cover stitches. Some machines are called sergers, though, when they’re not technically a serger. In order for a machine to be a true serger, it must contain a blade that will cut off the extra fabric as you sew. If the machine does not have a blade, it’s more often referred to as a coverstitch machine. But whether you need a true serger or not, Brother has a model available for you. So, make sure you know what you need in a machine to meet your needs and choose accordingly.

Number of threads

Brother sergers come with a variety of thread options, anywhere from 2 threads to 4. But they’re not all the same. Some models that have 3 or 4 thread options don’t have the capability to do 2 threads, so it’s important to know what you need for the projects you have planned.

Using 2 threads with your machine will allow you to create a standard stitch, whereas 3-4 threads will give you a seam with some stretch capabilities, or you can even complete a rolled hem. A 4 thread is often called a “mock safety stitch” because while it has much of the strength as a true safety stitch or separate seam, it’s still not quite as strong.

Depending on the types of stitches you need to complete, you can find out how many threads you need your serger to handle.

If you need a machine that can handle 2, 3, and 4 threads, then check out the Brother ST4031HD or the Brother 2340CV.

Stitching options

Brother sergers come with different stitching capabilities. You can choose settings from stitch length and width, to different stitches like the cover and chain stitching. A chain stitch is a stitch that looks like a regular straight stitch on top but has a series of loops on the bottom. This stitch is both stretchy and strong. Most Brother sergers come with dials that allow you to adjust the width and length of the stitch itself.

For a model that has the largest range options, check out our Editor’s Choice, the Brother Designio DZ1234, which has an impressive stitch width of 3.0 millimeter – 7.0 millimeter.

And some machines will also perform a coverstitching, which is a hem that looks professional with two rows of stitching on the top and a serger-like stitch on the bottom. If you’re looking for a machine that can handle a coverstitching, look at the Brother 2340CV, which also comes with a variety of accessories.


If you have a lot of sewing to complete, especially if you sew for more commercial purposes, then the speed of your Brother serger can matter a great deal. The faster the machine, the more things you can create. Though sometimes a fast machine may be hard to control, especially if you’re not used to working at higher speeds. The easiest way to tell the speed of a serger is to understand how many stitches per minute they can produce. For the high-end of 1300 stitches per minute, check out the Brother 1034D or the Brother ST4031HD. But if you’re not concerned about speed, than the 1000 stitches per minute of the Brother CV3440 may be a great choice for you.


Brother sergers and overlock machines come with many different convenient options—everything from lights to make it easier to work to removable arms, and dials and controls. Most Brother machines come standard with an LED light. This can make threading the machine easier due to the illumination.

If you’re someone who works with a lot of cuffs or necklines, then a removable free arm is a necessity. The free arm lets you more easily sew cuffs and other stitches on cylindrical projects.

If you’re looking for a model that comes with convenient controls and convertible free arm/flat bed surface, then our Editor’s Choice, the Brother Designio DZ1234, may be the best option for you.


Dimensions matter when it comes to sergers because you’ll need to know if the serger can handle the projects you’re tackling, especially if you’re working on bigger items like quilts, but you’ll also need to know if your workplace is large enough to accommodate the machine itself. If you’re someone who wants a large serger for large products, look no further than the heavy-duty Brother ST4031HD, which is built to handle large projects thanks to its extendable table. But if you need something smaller, the Brother 1034D is a compact serger that may work for you and your needs.


Another consideration that can be important for a serger is the weight.

If you’re someone who has the space to operate your serger without ever moving it, then a heavy model may not be an issue for you. If you’re working out of a smaller space and are required to move, or occasionally store, your serger to complete other tasks, then the more lightweight the serger, the easier it will be for you to move.
For the lightest model on our list, check out the Brother 2340CV model, which weighs under 17 pounds.

Brother warranty

One of the best features of choosing Brother as a brand name over other serger and overlook machines is the included warranty. Brother sergers come with a spectacular 25-year limited warranty for the Chassis Casting, 1-year for parts and labor and additional warranty for some electronic components. And not only that, they offer a lifetime phone technical support, too. This is a machine that the company expects to work for decades, which means it can be a great choice for users who are serious about longer-term serger and who want a machine that will last for years.

Other features

Some Brother serger models come with color-coded threading. Machines that have this capability, such as the Brother Designio DZ1234 and Brother 2340CV, make it so easier to thread the machine because the color-coding prevents you from mixing up the threads occasionally.

Some models also come with extra, specialized feet, which can allow you to tackle blind hems, gathering, and even piping. If you’re looking for more features, some models also come with a pressure foot pedal, allowing you to control the speed of the machine with your foot, freeing up your hands to continue working elsewhere.

5 Outstanding Brother Sergers - Reliable Brand for Simpler Overlocking!Prices

Since Brother is a well-known, well-respected brand, the prices tend to be on the higher end. But like almost every appliance, you get what you pay for. That doesn’t mean that you automatically have to choose the most expensive Brother serger if you want to complete projects. No. It’s more important to choose a Brother serger based on your needs and requirements. If you don’t need a machine that has a free arm, or different feet or 2, 3, and 4 thread options, then it’s possible there’s a cheaper option available for you that will still tackle all the capabilities you’re asking of it, and more, while not impacting your wallet.

If you’re looking for a Brother serger that won’t cost the earth, check out the Brother 1034D. We think this overlocking model is amazing because it costs only $154 and may be a great choice as a serger for beginners or for someone searching for less expensive products. But if you want a higher-end model and have the money to spend, then look no further than the Brother Designio DZ1234. This model will run you about $300, but it comes with a free arm convertible surface, and three different feet included.


Before threading your Brother serger, it’s important to follow these quick steps first. Many people complain that sergers can be difficult to thread, but as long as you do everything correctly, it will make an easier task for you:

  • Raise the telescoping thread tree to the highest position possible
  • Align the thread holders above the spool pins
  • Thread the holder on the thread tree
  • Thread the spool pin
  • And make sure it’s in the correct position.

Then, when you’re ready to finish threading, make sure you always thread in this order: upper looper, lower looper, right needle, left needle.

If you’re experiencing skipped stitches, there can be a variety of reasons for that, including installation or bad needles. If your needle is bent or the tip has become blunt, you’ll need to replace the needle. Before that, though, make sure that the needle is properly installed, and that you’re using the correct size needle for your machine and for the project you’re tackling. Check your presser foot pressure (if applicable) to make sure it’s increased enough, and then don’t forget to adjust the thread tension accordingly.

Adjusting the thread tension on a Brother serger can often seem intimidating for users simply because there are so many dials. But it’s actually quite simple when you learn what to do. The yellow marked tension dial is for the left needle, and the pink dial is for the right needle. Green is for the upper looper, and blue is for the lower looper. Once you know which thread tension you need, then just dial up to increase the tension or dial down to decrease the tension. This should allow you to capture the tension you’re looking for on any of your threads.

Our Verdict

Brother serger or overlock machines are a great way to take your sewing business or projects to the next level, and if you’re shopping for a serger, chances are there’s a Brother model that fits your needs.
