How is stitch length measured?

The stitch length is measured by measuring the number of lengths of thread found within one inch. Stitch counters are available from A&E that make this measurement easier, however, you can place a ruler next to the seam and perform the same task.

What is the stitch length?

Stitch length is basically how long each stitch is sewn by your sewing machine. Changing the stitch length adjusts the feed dogs, which controls how much fabric is pulled through with each stitch. For a shorter length, less fabric is pulled through.

How do you calculate stitches per minute?

The stitches per minute is how fast the head is rotating with every rotation making a single stitch. To calculate the stitches per minute divide the motor rpm by your reduction ratio. Once you’ve calculated your stitches per minute, you can determine your stitch length and sewing speed.

What is the best stitch length?

For piecing, 2.0 mm or about 13 stitches-per-inch is preferred. The default stitch length (what the machine automatically sets to) is usually longer than 2.0 mm. I recommend that quilters reset it to 2.0 mm for piecing, or to about 13 stitches-per-inch. Stitch length of 2.0 mm is perfect for piecing.

How do you count stitches per inch?

Measure 4 inches, count the stitches (half-stitches, too) and divide this number by 4 (it may be a fraction). This is stitches per inch. If you have MORE stitches per inch than your pattern calls for (see diagram to the left), your stitches are TOO SMALL. Try a LARGER NEEDLE.

How long can a straight stitch be?

On most machines the straight stitch length can be adjusted from zero (stitching in one place without moving the fabric) to up to 6mm long. When sewing seams, use a straight stitch 2mm to 2.5mm long, depending on the fabric. A shorter stitch length is used on lightweight fabrics that tend to pucker.

Why are my stitches not straight?

If your thread is pulled tight on the underside and not forming an even stitch then (counter-intuitively) it’s usually the top thread tension that’s wrong. Sometimes very lightweight fabrics such as sheers can get dragged down into the machine so it’s a good idea to use a straight stitch plate.

How do you calculate strength of a stitch?

Take the number of stitches per inch times the strength of your thread times the ratio 1.5 (the average loop strength of thread on lockstitch sewing machines) to determine your seam strength in pounds per inch of sewing.

What is stitch per inch?

A sewing machine sewing at 5,000 SPM at 14 SPI will sew 9.9 yards of seam per minute. More stitches per inch will also consume for thread per inch of seam. This will contribute to higher seam strength and more elastic seams, but will also increase the consumption of thread required to sew the garment.

What is the best stitch length for sewing a straight stitch?

Set the machine for straight stitch, with a stitch length of 3 to 3.5mm. Use a SINGER Topstitching Needle, size 90/14 for medium weight fabrics, or a SINGER Topstitching needle, size 100/16 for heavier fabrics. Sew 1/4″ – 3/8″ from the edge of the fabric.

What should the tension be for a straight stitch?

The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.

Why is my zigzag stitch sewing straight?
