Singer 4423 Review: A Heavy-Duty Machine for Any Skill Level

If you’ve read my other reviews, then you know I love a good, solid, beginner-friendly sewing machine.  I know how tricky it can be to choose the right model for your needs, especially with so many varieties available. Today, I’m here to give you my thoughts on another well-performing heavy-duty sewing machine with this Singer 4423 review.

Excellent Choice for Beginners

When you’re first starting learning to sew, you want a machine that is user-friendly. But what does that mean? Even if you’ve never stitched a day in your life, you should be able to pull your new machine out of the box, thread the bobbin, and start sewing with relative ease.

The Singer 4423 has a few features that make it useful to a beginner.

It can handle most projects you throw at it. From jeans to lace, straight stitching to buttonholes, there’s a lot that this machine can do. When you’re first starting out, you may not know what tickles your fancy until you actually start sewing. Maybe you’re not destined for hemming jeans, but you want to start producing quality tote bags. This machine can do both.
Helpful diagrams. Little diagrams appear in strategic areas on the front of the machine. This is especially helpful if you forget which setting you need for your stitches, or where the bobbin thread is supposed to go. While you may want to watch a tutorial or two to get the hang of things at first, the diagrams are a helpful reminder in case you forget a step (or if you get interrupted).

In this Singer 4423 Heavy Duty Sewing Machine Review, you’ll hopefully find all the answers you need as to whether or not this model is right for you.

Key Features

The Singer 4423 Heavy Duty Sewing Machine features two large dials on the front and three on the top. To a beginner that may seem a little intimidating, but I assure you – it’s not as complicated as you think.

Let me break them down for you, from bottom to top:

  • Stitch selector. This machine has 23 built-in stitches. Choose from 6 basic stitches, 6 decorative stitches, and 10 decorative (plus a 1-step buttonhole).
  • Stitch length adjuster. Increase the size of your stitches to 6mm.
  • Stitch width adjuster. Adjust the width of your stitches (and this can move your needle position as well).
  • Needle positioner. Set your needle to center, left, or right.
  • Tension adjuster. Change the tension, depending on the project.

This machine also has an automatic needle threader, a metal frame, foot pedal speed control of 1100 stitches per minute, and several included accessories (including extra feet!).

Performance Over Aesthetics

Singer 4423 Heavy Duty Sewing Machine

I’ve seen other people complain about the look of the Singer 4423, and it does look a bit clunky. But I’ll tell you this much – what you see is what you get: an uncomplicated, user-friendly workhorse of a machine.

A sewing machine doesn’t need to have a sleek interface or a modern computerized look to it for it to be the right machine for you. All you need to worry about is whether or not it performs – and this machine can get the job done.

Automatic Needle Threader

Can’t figure out how to get that needle threaded? No problem. This machine has an automatic needle threader to take the guesswork out of it. Check the manual or watch a tutorial before you use it for the first time, but it’s not terribly tricky.

23 Adjustable Stitch Settings

While this machine doesn’t have the variety of some other models, 23 stitch settings are usually more than enough for most people. You can also change the length and width of your stitches to suit your needs.

High-Speed Stitches

This sewing machine can crank out over 1,100 stitches per minute. That’s more than double many other home machines. Controlling the speed with the foot pedal can be a little tricky at first, but with some practice, you’ll be a pro in no time.

Heavy-Duty Frame

This machine weighs around 17 pounds. It’s light enough to take with you (although you should invest in a hard case if you’re going to travel with it), but it’s also solid enough that it won’t fly off your table.

Pressure Foot Adjustment

Depending on your project, you can adjust the pressure of the presser foot. This is handy if you’re trying to swap back and forth between a fleece dinosaur costume or a dainty lace ballerina tutu.

Pros and Cons of the Singer 4423


Good machine for beginners or experienced sewers
Easy to use
Can handle a variety of projects
Heavy-duty design
High-speed stitching


It can be a little tricky to wind the bobbin the first few times, so make sure that you’re using a high-quality thread and follow the diagrams properly

Extra Singer 4423 Accessories

This machine comes standard with a bunch of extra goodies including:

  • All-purpose foot
  • Zipper foot
  • Buttonhole foot
  • Seam ripper
  • Auxiliary spool pin
  • Spool pin felt
  • Singer 4423 needles
  • Soft dust cover

You can leave all of these in the handy accessory tray. It’s also compatible with most other Singer accessories, should you decide to move on to more complicated projects.

Put it to the Test

Let’s take a look and see how the Singer 4423 stacks up against some similar models.

Singer 4423 vs 4452

Singer 4423 vs 4452

The Singer 4423 and the Singer 4452 are very similar machines, but they have a few differences to consider.

They both boast a high stitch speed of 1,100 stitches per minute and the same basic mechanics. The Singer 4452 has 32 built-in stitches, but the 4423 model only has 23. The 4452 also includes some extra accessories that you’d have to purchase separately for the 4423.

However, if you don’t need those extra stitches (because frankly, you’ll probably end up sticking with a few favorites) or extra accessories, then the Singer 4432 is still a great choice.

Singer 4423 vs 4432

Singer 4423 vs 4432

The only significant difference between 4423 and 4432 is the number of built-in stitches. The 4423 has 23 decorative and basic stitches, and the 4432 has 32.

But once again, most casual home sewers aren’t using a ton of different stitches, so you’ll probably be fine with the 23 that are included on the Singer 4423.

Additional Tips

To get full use of your machine, try using some of my handy tips:

  • If your machine is getting tangled up with thicker fabrics, try using a longer stitch length. The machine will do more work for you, and it’ll keep your fabric from bunching.
  • The stitch length wheel also controls needle position. Make sure it’s in the right place before you begin.
  • Standard stitches are indicated in black diagrams on the stitch wheel. If you want to switch to the stretch stitches, you need to make sure your stitch length adjuster is set to the little blue “s” position.
  • You probably won’t need to change your tension setting much if you keep your machine clean and free of debris, use new needles, and make sure you’re using high-quality thread. Cheap thread and a dirty machine can really hinder the performance of your Singer 4423.

Quick Start Guide

While there’s technically no way to get a quick start on any sewing machine, I’ve broken down some of the steps for you to make it a little easier. To get your Singer 4423 set up in no time, use this guide (and always refer to the manual if you’re confused!)

  1. Select good quality thread (not bumpy or oddly thick or thin).
  2. If the thread makes an “x” shape on its spool, use the machine’s horizontal thread spool. If it’s a stacked thread, use the vertical. You can also use the vertical spool for a double or twin needle.
  3. Don’t leave a gap when you put on your spool cap.
  4. Use a standard Class 15 plastic bobbin.
  5. Follow the diagrams on your machine and wind the thread around the guide.
  6. Thread the hole on the bobbin (use the little diagram if you have to).
  7. Trim the end of your thread, and make sure it’s a nice, tight wind.
  8. Place the bobbin into the drop-in bobbin area. There’s another diagram to help with that too.
  9. Use your finger and pull the thread out so that it securely stays in place.
  10. Undo the top bobbin threaded around the pre-tensioner.
  11. Make sure your presser foot is up, pull the thread firmly around the guides following the diagrams.
  12. Use the automatic needle threader to thread your needle.
  13. Turn your hand crank towards you for one full stitch (hang onto your thread ends!).
  14. Put your fabric into the machine, turn down your presser foot, and get sewing!

Hopefully, that removes at least some of the mystery of threading the bobbin and getting started. If you still need help, check your manual or watch some video tutorials.

Singer 4423 Review F.A.Q.

  • What kind of bobbins does this machine need?

    Answer: If you want to get the most from your machine, make sure that you’re using the correct Singer 4423 bobbins. The machine comes with standard plastic Class 15 bobbins, so stick with those when you’re repurchasing extras.
    The Singer 4423 bobbin size is a Class 15 (approximately 20mm x 11 mm).  The Class 15J is slightly curved, and may not work well in your machine.

  • Can you use it for quilting?

    Answer: Because this machine is heavy-duty, it can handle quilting projects. However, you’ll probably need to pick up a walking foot or additional presser feet.

  • How does it handle heavy fabrics like denim or canvas?

    Answer: It can sew denim and canvas, but make sure you’re using heavy-duty needles. Also, make sure that your settings are correct before beginning any project with thicker material (and that your machine is clean!)

Final Verdict

My final thoughts for this Singer 4423 review? It’s a versatile workhorse that is suitable for both beginners and experienced sewers. It may not be as flashy or have as many features as other models on the market, but it gets the job done quickly and efficiently.
