One of the most common mistakes when preparing for sewing is incorrect calculation of fabric consumption. Having bought the material “by eye”, you may encounter a sewing dead end: there is not enough fabric for subcuts or small details, or you will be left with an unnecessary cut for which you overpaid. In this article, we have collected universal calculation formulas, taken into account the width of the fabric and prepared a convenient table of fabric consumption for basic wardrobe items.

Basic factors affecting fabric consumption
Before purchasing fabric, it is important to understand that the consumption rate depends not only on the size of the clothing, but also on the technical characteristics of the fabric itself:
- Roll width: The standard width of suit and dress fabrics is 140-150 cm. Knitwear is often produced in a width of 180 cm (in stocking or linen), and natural silk and flounce - 110-120 cm.
- Size and height: For standard sizes (from 40 to 48), one length of the product is usually sufficient. Starting from sizes 50–52, the width of the parts does not fit into the same width of the fabric, so a double consumption is required.
- Pile direction and pattern: Fabrics with checks, stripes, large coupons or pronounced pile (velvet, corduroy, coat pile) require an additional 15% to 30% of the fabric to adjust the pattern and cut in one direction.
- Style and presence of folds: Draperies, folds, flounces, peplum and hood significantly increase the footage.
Calculation formulas for main types of clothing
For a standard figure and fabric width of 140–150 cm, simple approximate formulas are used:
- Straight skirt: Skirt length + 15–20 cm (for the waistband and hem allowance).
- Classic trousers: Pants length along the side seam + 15–20 cm (for hip circumference up to 100 cm). For OB > 100 cm - (Pants length × 2) or Pants length + 40 cm.
- Straight dress or blouse:Product length + Sleeve length + 20–25 cm (for processing the neckline, cuffs and hem).
- Coat or jacket: Product length + Sleeve length + 30–40 cm (for lining, collar and pocket flaps).
Summary table of fabric consumption (for width 140–150 cm)
| Product type | Sizes 40–48 (Height up to 175 cm) | Sizes 50–56 (Height up to 175 cm) | Note/Additional |
|---|---|---|---|
| Blouse/Long Sleeve Shirt | 1.3 - 1.5 m | 1.8 - 2.2 m | + 20 cm on cuffs and collar |
| Straight skirt (pencil) | 0.8 - 1.0 m | 1.3 - 1.5 m | The width of the belt is taken into account |
| Circle Skirt/Semi-Skirt | 2.0 - 2.5 m | 2.5 - 3.0 m | Depends on the length of the skirt |
| Classic trousers | 1.2 - 1.4 m | 1.8 - 2.0 m | For OB > 100 cm requires 2 lengths |
| Straight dress / sheath | 1.5 - 1.8 m | 2.2 - 2.5 m | Including short/long sleeve |
| Jacket/Blazer with collar | 1.6 - 1.8 m | 2.2 - 2.5 m | + Equal consumption of lining fabric |
| Demi-season coat / Trench coat | 2.5 - 2.8 m | 3.2 - 3.5 m | + 10–15% if there is a belt and stalemates |
How to distribute parts when cutting: layout and drawing
Before buying expensive fabric, the safest way is to lay out the pattern pieces on a table or floor, limiting the width of the fabric to two parallel strips (for example, 140 cm in scale or full size).
- Two-layer layout (with fold):The fabric is folded along the edge with the right side inward. Suitable for paired parts and folded elements (back, shelf).
- Spread layout:Used for asymmetrical styles, as well as to save fabric in complex cuts.
Tailor's advice
Always add +10% to the final calculation for shrinkage during decating. Natural fabrics (cotton, linen, wool, viscose) shrink significantly after wet-heat treatment (decatation) before cutting. And to make the layout as economical and accurate as possible, use proven ready-made patterns from our catalog with ready-made layout patterns.
Frequently asked questions (FAQ)
How much fabric should I add if the material is piled or checkered?
For fabrics with directional pile (velvet, corduroy, coat pile), add 15–20% to the consumption, since all parts are cut strictly in one direction. For a large check, add 20-30% to match the pattern at the seams.
How much lining fabric is needed for a jacket or coat?
The consumption of lining fabric is usually equal to the length of the product plus the sleeve length (minus the hem allowances), that is, approximately 20–30 cm less than the consumption of the main fabric.
How to calculate the fabric for a pleated skirt?
For bow or circular folds, fabric consumption is calculated as 3 lengths of the skirt plus allowances for hem and waistband.
