Needle types and their uses
The sewing machine needle that should be used depends on the fabric and thread thickness. Refer to the
following table when choosing the thread and needle appropriate for the fabric that you wish to sew.
Memo
z The smaller the thread number, the thicker
the thread, and the larger the needle
number, the thicker the needle.
z Use the ball point needle when sewing on
stretch fabrics or fabrics where skipped
stitches easily occur.
z Use a 90/14 to 100/16 needle with
transparent nylon threads, regardless of the
fabric being sewn.
z A 75/11 needle is already installed when the
sewing machine is purchased.

● The appropriate fabric, thread and needle
combinations are shown in the table
above. If the combination of the fabric,
thread and needle is not correct,
particularly when sewing thick fabrics
(such as denim) with thin needles (such as
65/9 to 75/11), the needle may bend or
break. In addition, the stitching may be
uneven or puckered or there may be
skipped stitches.
