Short answer

With the right needle, denim itself is rarely the problem; the hard part is the thick seams of a jeans hem. Use a denim (jeans) needle: SINGER recommends its Style 2026 "for sewing denim, jeans, and canvas", in 16/100.1 To cross thick seams, SINGER's 4452 manual uses a clearance plate, and one Brother manual a shim of the same thickness under the presser foot.2,3 For frequent jeans work, choose a heavy duty machine with a free arm for trouser legs.

Questions

Can a regular sewing machine sew denim?

Within limits: Brother's XM2701 manual warns against fabric more than 6 mm thick.4 SCHMETZ, for thick denim seams: "use at least size 90/14, although you may need to move up a needle size to 100/16."5

How do I sew over thick jeans seams?

Keep the presser foot level. SINGER: "The presser foot tilts as it sews on and off thick seams areas. The Clearance Plate keeps the presser foot level". Stop before the needle reaches the seam, lower the needle, raise the foot and slide the plate in from the back.2 A Brother manual: "place thick paper or fabric (with the same thickness as the fabric being sewn) under the heel of the presser foot".3 SCHMETZ also mentions a Jean-a-ma-Jig to help sew over thick intersecting seams.5

What stitch length for denim?

Longer. SINGER's HD4552 manual: "Use a longer stitch length when sewing heavier weight fabrics or when using a thicker needle or thread."6

Why does my needle break on jeans?

SINGER: it "can be an indication that the needle size is too small for the thickness of fabric being sewn"; also, do not push or pull the fabric, "but rather, let the feed dogs draw the fabric along."1

What is the best sewing machine for denim for beginners?

A heavy duty dial machine is the simplest start. See our [heavy duty guide](/sewing-machines/heavy-duty-sewing-machine/) for the SINGER 4523 and 4552 and Brother's Strong & Tough models, and our [beginners guide](/sewing-machines/sewing-machine-beginners/) for lighter machines.

Bottom line

For jeans, use a denim needle in 90/14 to 100/16 (16/100 for SINGER), a longer stitch, and a clearance plate or shim to keep the foot level on thick seams. Pick a machine with a free arm for trouser legs; if you hem jeans often, a heavy duty machine with adjustable presser foot pressure makes it easier.
