Sergers are valuable machines in apparel manufacturing, known for producing clean edges, strong seams, and professional finishes.
However, clients often ask an important question: what are the downsides? While sergers add efficiency and durability, they also come with limitations that must be understood before integrating them into production lines.
The cons of using a serger include higher costs, limited stitch variety, complexity in threading, lack of key functions like buttonholes and zippers, bulkier size, and the fact that they cannot fully replace a sewing machine.
At Jeanzio, we believe it’s important for clients to weigh both the advantages and disadvantages of sergers so they can make informed sourcing decisions. Let’s break down the main cons.

Are sergers more expensive than regular sewing machines?
Cost is often the first concern.
Yes, sergers are more expensive than regular sewing machines, both in terms of upfront purchase and ongoing maintenance.
Cost Factors
- Initial investment: Professional sergers cost significantly more than standard sewing machines.
- Maintenance: Requires specialized technicians for repairs.
- Thread consumption: Uses 3–5 spools at a time, increasing ongoing costs.
Clients need to factor these expenses into production budgets when deciding whether to expand serger use.
Why are sergers harder to use?
Sergers have a reputation for being less user-friendly.
Sergers are harder to use because they require complex threading, tension adjustment, and careful handling compared to regular sewing machines.

Complexity Challenges
- Threading: Multiple threads must be set correctly.
- Tension control: Each thread requires fine-tuning.
- Learning curve: Operators need more training time.
This can slow production if workers are inexperienced.
Do sergers have limited functionality?
Yes—sergers are specialized rather than all-purpose machines.
Sergers have limited functionality because they cannot sew buttonholes, zippers, darts, pleats, or decorative stitches.
What Sergers Cannot Do
- Attach zippers.
- Create buttonholes.
- Perform precise topstitching.
- Sew straight seams independently.
This is why factories still rely heavily on sewing machines for core garment construction.
Do sergers take up more space?
Space efficiency is important in factories.
Sergers are bulkier and take up more space than regular sewing machines, especially when multiple sergers are installed for large-scale production.
Why This Matters
- Factories with limited space may struggle to add serger lines.
- Maintenance access requires additional room.
- Larger size may reduce operator comfort in smaller setups.
Clients must plan floor layouts carefully when adding serger equipment.
Are sergers noisier than sewing machines?
Noise can affect worker comfort in production lines.
Yes, sergers are noisier than sewing machines due to their higher speed, multiple thread systems, and built-in trimming knives.

Effects of Noise
- May require additional hearing protection in large facilities.
- Can cause fatigue in long production shifts.
- Contributes to overall factory noise pollution.
Noise management becomes necessary when operating multiple sergers simultaneously.
Do sergers use more thread?
Thread consumption is significantly higher.
Sergers use more thread than sewing machines, as they require 3–5 spools at once to create reinforced seams.
Thread Considerations
- Cost: Higher thread use increases expenses.
- Storage: Factories need more space for bulk thread.
- Waste: Unused ends and trimmings can add up.
Clients must account for increased thread demand in material planning.
Do sergers require more maintenance?
Yes—maintenance is more frequent and complex.
Sergers require more maintenance than sewing machines because of their multiple moving parts, knives, and higher thread tension systems.
Maintenance Challenges
- Knife replacement after extended use.
- Cleaning to prevent lint buildup.
- Tension adjustments for different fabrics.
Specialized maintenance adds costs and downtime.
Can sergers damage fabric?
Inexperienced use can create quality problems.
Sergers can damage fabric if improperly set, as their knives cut continuously and high tension can distort lightweight fabrics.

Potential Issues
- Over-trimming edges.
- Puckering on delicate fabrics.
- Cutting mistakes that ruin panels.
Proper operator training is essential to avoid wastage.
Are sergers less versatile than sewing machines?
Yes, versatility is a key limitation.
Sergers are less versatile because they specialize in finishing edges, while sewing machines handle a wider range of garment construction tasks.
What Sewing Machines Can Do (but Sergers Cannot)
- Topstitching for jeans and jackets.
- Buttonhole creation.
- Decorative embroidery.
- Attaching zippers and fasteners.
Sergers add value but cannot replace the versatility of sewing machines.
Why should clients understand the cons of sergers?
Clients who know the downsides can make smarter sourcing decisions.
Understanding the cons of sergers helps clients budget realistically, design efficient production lines, and balance machine use with sewing machines.
Business Implications
- Avoids over-reliance on one type of machine.
- Prevents unexpected costs in thread and maintenance.
- Ensures factories deliver products efficiently and consistently.
At Jeanzio, we help clients weigh pros and cons so their production strategies are effective.
Conclusion
The cons of using a serger include higher costs, complex operation, limited functionality, more maintenance, and higher thread consumption.
Sergers cannot replace sewing machines, but they provide finishing strength and quality that sewing machines alone cannot deliver.
At Jeanzio, we combine both machines strategically, ensuring our clients’ products meet global standards in durability and appearance while keeping production efficient and sustainable.
