Why Are Jeans Called Denim?

Have you ever wondered why jeans are called denim?
As a streetwear and denim manufacturer at FuKiApparel.com, I’ve spent years working with denim fabrics — from raw selvedge to stretch blends.
In this post, I’ll break down the true origin of the word “denim,” how it evolved into the world’s most iconic fabric, and what it means for today’s fashion brands.

The Origin of the Word “Denim”

The word “denim” comes from the French phrase “serge de Nîmes”, meaning “fabric from Nîmes,” a city in southern France.
This cotton twill fabric was originally woven to be strong and durable — perfect for workwear.

When the material reached America in the 19th century, tailors simplified the name from “serge de Nîmes” to denim.
Over time, denim became synonymous with rugged blue work pants — what we now call jeans.


How Denim Became Jeans

In the late 1800s, Levi Strauss and Jacob Davis used denim to make reinforced trousers for miners.
The riveted construction made them long-lasting, and the term “jeans” — derived from “Gênes” (the French word for Genoa, Italy) — became associated with the garment.

So, in short:

  • “Denim” = the fabric
  • “Jeans” = the garment made from denim

Today, nearly every major fashion house — from Levi’s to Diesel — builds collections centered around this historic textile.
