Selvedge Denim: What It Is and When It Is Worth It

What selvedge means

Selvedge — also spelled selvage, both are correct — is the finished self-edge produced by a shuttle loom. The weft turns back on itself at the edge instead of being cut, so the edge cannot fray and needs no overlock. That narrow band, often with a coloured line running through it, is the selvedge ID.

Shuttle looms are narrow, typically 31 to 35 inches, and slow. That is the real reason selvedge costs more: it is a production constraint, not a quality grade.

What selvedge does not tell you

Selvedge is not a synonym for quality, and not a synonym for raw. You can have poor selvedge and excellent wide-loom denim. What it does reliably indicate is a shuttle loom, which usually means slower weaving, more irregularity in the yarn and the slubbier character people associate with heritage denim.

It also affects yield. A 33 inch selvedge roll and a 60 inch wide-loom roll are not comparable per yard — work the marker before comparing prices.

When to specify it

When the selvedge ID will be visible — a cuffed hem, an exposed outseam — or when the programme is sold on heritage construction. If neither applies, wide-loom denim of the same weight and hand will usually cost less per finished garment.
