Sewing Machine Buttonhole Foot Types: Automatic vs Manual Guide

Buttonholes are the most intimidating thing for most home sewists, but the foot you use makes all the difference. There are two main types of buttonhole feet: automatic (one-step) and manual (four-step). Each works differently and not every machine supports both.

Automatic Buttonhole Foot (One-Step)

An automatic buttonhole foot has a sensor that detects the size of your button. You place the button in a holder at the back of the foot, the machine measures it, and then it sews a buttonhole exactly that size in one continuous operation.

Which machines come with one: Most Brother and Janome computerized machines that cost over $300 include an automatic buttonhole foot. Many Singer machines in the $150 to $300 range also include one.

How to use it:

Install the automatic buttonhole foot.
Place your button in the holder at the back of the foot.
Lower the foot onto your fabric (which should be interfaced and stabilized).
Select the automatic buttonhole stitch.
Press the start button or push the foot pedal.

The machine does the rest — it sews the left side, the bar tack, the right side, and the second bar tack, then stops.

Manual Buttonhole Foot (Four-Step)

A manual buttonhole foot is a simpler foot that does not have a sensor. You control each of the four sides of the buttonhole manually using the stitch width and stitch length controls. These feet usually have markings to help you measure the buttonhole length.

Which machines come with one: Most mechanical machines under $200, and many vintage machines, come with a manual four-step buttonhole foot. Some come with no buttonhole foot at all and expect you to make buttonholes with the zigzag foot.

How to use it:

Install the manual buttonhole foot.
Mark the buttonhole length on your fabric.
Select step 1 on the stitch selector (sews the left side).
Press the foot pedal until you reach your mark.
Select step 2 (sews the bar tack at the top).
Select step 3 (sews the right side).
Select step 4 (sews the bar tack at the bottom).

You need to manually align each pass. It takes practice to make the sides match.

Common Errors with Both Types

Fabric is not flat. If the fabric bunches up under the foot, the buttonhole will be distorted. Always use interfacing on the fabric behind the buttonhole area.

No stabilizer. Without stabilizer, the fabric stretches and the buttonhole ends up rippled or uneven. Water-soluble stabilizer or tear-away stabilizer works well.

Foot not clicked in all the way. On snap-on machines, the buttonhole foot must click fully into place or the sensor (on automatic feet) will not contact the foot correctly.

Button in the wrong position. On automatic feet, if the button is not fully seated in the holder, the machine will sew a buttonhole that is too small or too large.

Which Type Should You Use?

If your machine supports automatic buttonhole feet, use it. The results are more consistent and you do not need to measure anything. If you have a mechanical machine, practice the four-step method on scraps until the sides are even. A well-made four-step buttonhole is just as good as an automatic one — it just takes longer to perfect.
