Fabric Consumption
Fabric consumption is the quantity calculated from the fabric width used, marker layout, pattern matching, seam allowances, and other factors as the length of textile needed to make one garment or one product item.

Definition and Overview
Fabric consumption is the length of textile needed to cut and sew a product. It is generally managed in meters or yards, and is used for planning, quotations, ordering, and production scheduling as the amount required per garment. It may refer either to the length itself or to the calculated figure.
Fabric consumption is not a term that describes the texture, function, or appearance of textile. It is a production quantity determined by fabric width, pattern size, size range, and cutting method. It is important for understanding the amount of textile needed, but it is distinguished from bolt length and inventory quantity.
Factors That Affect Fabric Consumption
Even with the same design, the narrower the textile width, the more length is usually needed; the wider the width, the less may be needed. However, depending on hardware placement and grainline restrictions, the width may not always be fully usable. It is basic practice to confirm the pattern shape and marker layout when calculating consumption.
Patterned items such as checks, stripes, and borders may require more fabric consumption than plain items because of pattern matching. Textiles with a nap, directionally printed materials, and fuzzy materials also require the cutting direction to be aligned, which can reduce lay efficiency.
- Pattern dimensions and grading by size
- Textile width and usable width
- Seam allowance, facings, pockets, and other attached hardware
- Cutting direction such as pattern matching, nap, and grainline
- Cutting loss and allowance for defects removed during inspection
Main Uses and Handling in Production Management
Fabric consumption is used for all apparel products, including shirts, pants, jackets, dresses, and coats, regardless of whether they use woven fabric or knit fabric. The meaning of the term does not change by item seasonality, but for products that use multiple materials such as lining, quilt batting, and outer fabric, each fabric consumption is managed separately.
In mass production, order quantity is determined not only by multiplying the consumption for one garment by the number of garments produced, but also by taking into account cutting loss, textile defects excluded during inspection, and the required amount for each lot. The estimated consumption at the sample stage and the confirmed consumption for mass production may differ.
Calculation and Handling Notes
Accurate fabric consumption is confirmed by marker making under conditions based on the finalized pattern, textile width, grainline, and pattern direction. It is important not to judge only from the standard textile width, but to confirm the usable width after excluding selvage edges and areas prone to defects. Conditions may also differ by size, color, and pattern.
For textiles that may shrink through washing or processing, the shrinkage rate is checked before cutting. If necessary, pre-treatment and straightening are performed, and the pattern and consumption are set to account for shrinkage. Stretchy knits and textiles that tend to skew are also affected in cutting accuracy by tension during spreading and by release conditions.
Differences from Similar Terms
Textile width is the crosswise dimension of the textile, while fabric consumption is the required length. A roll is a trade and management unit for a fixed quantity of textile and is different from fabric consumption. A garment set may refer to the amount of textile prepared or sold for one garment, but that amount does not necessarily match the actual required consumption.
Marker making is the process or layout diagram of arranging patterns efficiently on textile. Fabric consumption is the required length obtained as a result. Pattern matching is the adjustment made to align patterns when sewing patterned materials together, and it is one factor that can increase or decrease fabric consumption.
Frequently Asked Questions
How is fabric consumption calculated?
Using the finalized pattern, set conditions such as textile width, usable width, grainline, pattern direction, and seam allowance, then make the marker and determine the required textile length. A rough estimate can be made from the pattern dimensions, but confirmation through actual marker making is necessary for mass production orders.
Why does patterned textile require more fabric consumption?
Checks and stripes require pattern matching so that the design lines up at the seams. As a result, it is harder to arrange the pieces freely and compactly, and cutting loss may increase. The degree of increase varies depending on the pattern size, directionality, and design.
Do shrinking textiles require more fabric consumption?
Depending on the shrinkage rate and whether the product will be washed after sewing, pre-cut treatment or pattern adjustment may be necessary to secure the finished dimensions. Rather than increasing fabric consumption uniformly, the shrinkage behavior should be confirmed through a preliminary test and judged together with the cutting conditions.
