How do you adjust stitch length on a sewing machine?

Which part of the sewing machine is used to adjust the stitch length?

For a basic sewing machine look for the dial or knob with either “length” written next to it or the illustration that looks like a dashed line gradually increasing in size. For modern computerized machines look for a selection on a touch screen or a button to press for adjusting the stitch length.

What are the settings for a straight stitch on a sewing machine?

The settings for straight stitching are as follows.

  • Set the stitch length to F-4.
  • Set the stitch width at 0.
  • The needle position can be set to M (Middle), L (Left), or R (Right). – For twin needle sewing, always set at M.
  • Install the zigzag presser foot.

What is a normal stitch length?

The average stitch length for mid-weight fabrics is 2.5 to 3 mm/10 to 12 spi. The average stitch length for fine fabrics is 2 mm/13 to 20 spi. For heavier fabrics, basting, or topstitching, use 4 to 5 mm/5 to 6 spi.

What is the regular setting for the stitch width?

A straight stitch has no width so it makes sense to set the dial at “0”. However, each machine varies so you will want to set the Stitch Width dial at the position where the needle is centered over the stitch plate. This will give you the most accurate seam allowance.

Why is my zigzag stitch sewing straight?

If the upper thread appears as a single line, the lower thread is incorrectly threaded. Instead of the appropriate tension being applied to the lower thread, it is pulled through the fabric when the upper thread is pulled up.
