Indian denim mills typically offer weights from around 4 to 6 oz for shirting and dresses, 7 to 9 oz for lightweight jeans and summer bottoms, 10 to 14 oz for standard jeans and jackets, and 15 oz and above for heavy, workwear-style denim. Denim weight is expressed in ounces per square yard, and it is the first specification a buyer should fix because it affects yarn count, loom speed, price, shrinkage and the hand of the garment.
Most of the volume from Indian mills sits in the 10 to 13 oz band, which is where stock programmes are deepest and lead times shortest. Weights outside that band are available but are more often made to order.
Weight bands and typical uses
- 4 to 6 oz: shirting and dress denim, often in finer yarn counts, lighter indigo shades or chambray constructions.
- 7 to 9 oz: lightweight jeans, summer trousers, children's wear and many women's stretch qualities.
- 10 to 12 oz: the core jeans range for most brands, offered in rigid, stretch and comfort stretch.
- 12.5 to 14 oz: heavier five-pocket jeans, jackets and premium men's lines.
- 15 oz and above: heavyweight and selvedge-style denim, usually rigid, with longer development times and stricter minimum order quantity (MOQ) terms.
How weight is measured and stated
Mills state weight in oz per square yard, sometimes alongside grams per square metre. One oz per square yard is roughly 34 grams per square metre, so a 12 oz denim is around 400 gsm. Weight is measured by cutting a template and weighing it, following methods such as ASTM D3776 or ISO 3801.
Ask whether the quoted weight is before or after finishing and whether it is in the relaxed or loomstate condition. Sanforising and washing increase weight per unit area because the fabric shrinks, so a fabric sold as 12 oz finished may have been woven lighter. Tolerance on weight is usually around plus or minus 5 percent, and it should be written into the purchase specification together with the test method.
Choosing a weight for your product
Lighter weights wash faster, drape better and suit warm markets, but they show wear sooner and are harder to keep flat through garment washing. Heavier weights give structure and durability and age attractively, but they increase shipping weight and need stronger sewing threads and needles. Jackets and heavier outerwear usually start at around 12 oz, while shirts and dresses rarely go above 7 oz.
Stretch qualities are usually offered between about 8 and 12 oz because elastane is harder to control in very heavy constructions. If you need a stretch fabric above 12 oz, allow extra development time and expect a higher MOQ.
How we help
We ask mills for their current stock weight charts, visit the plants that match your range and send sealed samples to an NABL-accredited lab to confirm weight, shrinkage and fastness. We supervise loading, send weekly updates and set you up with one approved supplier and one backup. A free 20-minute sourcing review is the easiest way to start.
