I am starting up this thread for people who may be new to denim and wondering what does the weight of the denim mean. Feel free to ask questions or discuss on denim weights here too.

Question: How do they determine the weight?
Answer: The weight refers to how much a yard of fabric weighs. A yard of 14 oz. denim weighs 14oz.

Question: I've seen denim listed from 5 oz to 20 oz. How do I know what to buy without touching it.

Answer:The swatches shown here are from fabric.com. Each swatch is labeled with the fabric information, fiber contents, care instructions and the width. Almost all online retailers offer fabric swatches.

A 20 oz denim is not going to bend and move for most garment uses. A 5 oz denim is not going to provide heavy denim jeans or jackets, however it will make wonderful shirts, skirts and dresses that will drape well. Knowing that denim runs from 5 to 20 oz and that the less the weight, the lighter, softer, loft the denim will have, you can purchase or request samples of the weights you believe are in the scope you are looking for. Looking at the samples in the photo, an 8oz denim is just a tad more pliable and soft than the 9 oz. The 9 oz sample is just a tad more pliable and soft than the 10 oz sample. Durability wise they are pretty much identical. The real difference comes in at the drape and flexibility.
Traditionally, 12 to 14 oz is used for denim jeans. It will not ruffle or drape if you were making a full skirt say for square dancing.
