A garment bill of materials lists every material needed to make a style, with specification, placement, consumption and supplier. How to structure a BOM, calculate quantities by color and size, and avoid the errors that cause shortages.
How to calculate fabric consumption for knit garments (by weight, from panel areas and GSM) and woven garments (by length, from the marker), with worked examples, wastage allowances and the mistakes that cause fabric shortages.
A garment cost sheet adds fabric, trims, cost of making, processes, testing, commercial costs and profit to reach a price. This guide walks through each element with a worked T-shirt example and the checks that stop losses.
The panel method for knit fabric consumption: list every panel, calculate area and weight by fabric, add allowances, and total by kg per dozen. Worked example for a hoodie with body fabric and rib.
The marker decides how much fabric an order uses. How markers are planned, what limits efficiency (grain, direction, matching, width), how to calculate marker efficiency, and how to improve it without hurting quality.
Fabric is the largest cost in most garments, and the cutting room decides how much of it becomes garments. Where fabric is lost, how to measure it, and practical ways to cut waste through markers, spreading, end loss control and roll planning.
The body block method for calculating fabric consumption of a basic T-shirt in kg per dozen, with a worked example, how to handle neck rib, size ratios and wastage, and how to check the estimate against a marker.
