Here’s our guide to the most important sewing machine features to consider when shopping and help you decide which sewing machine is best for you.

From budget units to computerised sewing machines, there are many different model sewing machines to choose from

Although all sewing machines share the same basic function, the sheer range of features available on different models makes choosing the best sewing machine far from simple. Here we guide you through some key sewing machine features to look for so you can better understand what to look for when shopping and how to find the perfect sewing machine.

Types of sewing machines

Electronic sewing machines

Electronic sewing machines have a single motor that drives the needle, in conjunction with a feeding mechanism, through your fabrics. The motor is operated by a foot pedal –press harder on the pedal to sew faster – leaving both hands free to guide the fabric. Most have a dial on the side that lets you change stitch type and length. Available in a wide choice of models with prices ranging from around £50 to £300, electronic sewing machine are great all-rounders suitable for both novices and experienced sewers alike.

Computerised sewing machines

Computerised sewing machines have built-in computers that automate stitching, making them simple to use. Operated by touchpad screens or LCD displays, they offer hundreds of different stitches and patterns, and can automatically adjust the length, tension and speed for those you select. Most can memorise your stitches so you reuse them again in the future, while premium models let you program your own embroidery patterns or download designs from the internet. With prices starting at around £250 and rising to more £2,000, a computerised sewing machine can be a major investment. However, they’re far more versatile than electronic machines and let you complete sewing project faster and more effectively.

Overlocker machines

Overlocker machines give a professional finish to the seams and hems of a garment by trimming excess fabric as they stitch. With their limited functionality, overlockers need to be bought in addition to a sewing machine. 

Sewing machine features to look for

Automatic buttonholer

An automatic buttonholer lets you sew a buttonhole in one step without having to stop and turn the fabric or manipulate a dial. Some sewing machines let you place the button in a slot on the foot, so the machine can sew the correct sized buttonhole to fit.

Auto thread tension 

Some sewing machines automatically calculate the correct thread tension for your fabric automatically, although most offer an override option so you can adjust this manually.

Feed-dog adjustment

Feed dogs are the zigzag shaped teeth that guide your fabric through the machine when you are stitching. All machines should allow you to lower the feed dogs below the sewing surface to do free-style embroidery or darning.

Free arm

This cylindrical arm on a sewing machine lets you sew sleeves and trouser legs. It is usually concealed in the body of the machine, so you first need to remove part of the machine bed so the arm protrudes.


Choose a sewing machine with easy-to-use, responsive controls. Electronic machines, for example, should respond to variable pressure on the foot pedal, while dials and touchpads should be easy to read and use. In addition, ensure there’s enough room to the right of the needle for your fabric and hands.


Consider how you plan to use and store your sewing machine. If you have to haul it out of a cupboard or other storage place every time you want to sew, look for a lightweight machine that’s easy to lift. If you sew home furnishings or upholstery, consider buying a sturdier machine that copes well with heavier fabrics.

Integrated dual feed

Useful when sewing two pieces of fabric together such as in quilting, this ensures both fabrics feed smoothly across the sewing plate avoiding ruching.

Needle position

This lets you move the needle from left to right to change the stitching line, or move it up or down when you stop stitching. With the needle down, you can lift the presser foot and turn the fabric to sew in a different direction without creating a jump stitch.

Automated needle threader 

A hook and spring operation that guides the thread through the eye of the needle. A handy feature that helps prevent eye strain and gets you sewing faster than a mechanical needle threader.

Lock stitch facility 

This ensures all stitches are securely locked off at the end of the sewing sequence by using a reverse stitch.

Presser foot

Your sewing machine may come with several presser feet, which hold the fabric against the feed dogs. You can buy additional feet for your machine but look for a multi-purpose foot, a zipper foot and buttonhole foot as a minimum. The ability to adjust foot pressure is also useful for sewing differing fabric thickness and weights.

Top loading bobbins

With older machines, the bobbin must be slotted into a recessed compartment, which can be a little fiddly. With some modern machines you can drop the bobbin in at the top of the machine, saving time, and its clear cover lets you see when thread is running low.

Stitch selector 

On basic models, you change stitch type by turning a dial on the side on the machine. Computerised machines have touchpads and LCD screens that let you select from hundreds of stitch types.

Which sewing machine is right for you?

How often will you use a sewing machine

There’s little point buying an expensive sewing machine with lots of features if you plan on using it for the occasional sewing project or repair job. If so, opt for a basic, lightweight electronic sewing machine that can be easily stored when not in use.

On the other hand, if you’re a passionate hobbyist or dressmaker who uses a sewing machine regularly, then a model with plenty of stitch functions, accessories and time-saving add-ons such as one-step buttonholes and seam neatening is a good choice.

What will you use the sewing machine for?

Along with frequency of use, you should consider how you plan to use your sewing machine as different models suit different tasks.

Simple tasks and repairs

If you’re a beginner or sew only occasionally, then a basic electronic sewing machine for around £100-£200 will suffice. Choose a model with a range of stitches – including a straight stitch in various lengths, a choice of zigzag stitches and an automatic buttonhole – along with a selection of foot attachments.


If you enjoying making clothes, then opt for a mid-priced sewing machine with a wide range of features. These should include a free arm for sewing sleeves and pockets, and a decent range of machine feet such as a concealed zipper foot, blind hem foot and piping foot. If you can afford it, consider a model that has an overlocker stitch, for neatening seams.

Embroidery and crafts

If budget allows, plump for a computerised sewing machine that offers a wide range of stitches and pre-programmed patterns so you can create multicoloured hoop embroidery designs.
