Twill Weave Explained

In brief: Twill is a fundamental weave structure recognised by its diagonal parallel ribs. It is made by passing weft threads over one or more warp threads then under two or more, with each row offset to form the diagonal, which typically runs at 45 to 75 degrees. Twill drapes better than plain weave and offers higher tear resistance, less soiling and less wrinkling. It underpins denim, chinos, gabardine and herringbone, with evidence of twill in Egyptian burial cloths from around 6500 BCE.

What is twill weave?

Twill is one of the three foundational weave structures in textiles, and it is instantly recognisable by the diagonal parallel ribs running across its surface. The diagonal is created by passing the weft thread over one or more warp threads and then under two or more, while offsetting the pattern by one thread on each successive row. This staggering builds the characteristic diagonal line, which typically sits at an angle between 45 and 75 degrees depending on the construction. Unlike a plain weave, which looks the same in both directions, twill has a clear front and a distinct diagonal grain.

Why twill performs well

The twill structure brings several practical advantages over plain weave. The offset interlacing lets the threads pack more closely yet still move, so twill drapes better and feels more supple. It also offers higher tear resistance, hides soiling more readily because of the textured diagonal surface, and wrinkles less, which is why twill fabrics are so common in hard-wearing everyday clothing. These qualities make it a workhorse weave: durable enough for rugged trousers and outerwear, yet refined enough for tailored chinos and smart gabardine.

Twill fabrics you already know

Many of the most familiar fabrics are twills. Denim is the classic example, woven as a 3/1 right-hand twill, where the weft passes under three warp threads then over one. Chinos, gabardine and herringbone are all twill-based too, each varying the angle, direction or yarn to produce a different look and weight. Twill is also ancient: evidence of the weave appears in Egyptian burial cloths from approximately 6500 BCE, showing how long this structure has been valued for combining durability with a refined surface.

Twill Weave at OD's Designer Clothing

At OD's Designer Clothing, twill weaves feature across chinos, trousers and denim from Jacob Cohen, BOSS and True Religion, giving those pieces their drape, durability and clean diagonal grain. Recognising a twill by its diagonal ribs helps you understand why a pair of chinos or jeans hangs and wears the way it does.
