Fabric Consumption Formula — Made Super Simple

## 🧵 Fabric Consumption Formula — Made Super Simple

### 🎯 What is "Fabric Consumption"?

It simply means: **How much fabric do you need to make one garment?**

---

### 📐 The Basic Formula

$$\text{Fabric Consumption (meters)} = \frac{(\text{Length} + \text{Allowance}) \times (\text{Width} + \text{Allowance}) \times \text{No. of Panels}}{\text{Fabric Width (in cm)} \times 100}$$

### ✅ Step-by-Step with a Simple Example

Let's say you're making a **basic T-shirt**:

| Part | Measurement |

|------|------------|

| Body Length | 70 cm |

| Chest Width (half) | 50 cm |

| Sleeve Length | 22 cm |

| Sewing Allowance | 5 cm each side |

| Fabric Width | 160 cm |

---

**Step 1 — Calculate the BODY piece:**

> (70 + 5) × (50 + 5) × 2 panels

> = 75 × 55 × 2 = **8,250 cm²**

**Step 2 — Calculate the SLEEVE piece:**

> (22 + 5) × (30 + 5) × 2 sleeves

> = 27 × 35 × 2 = **1,890 cm²**

**Step 3 — Add all pieces together:**

> 8,250 + 1,890 = **10,140 cm²**

**Step 4 — Convert to meters using fabric width (160 cm):**

> 10,140 ÷ 160 = 63.4 cm = **~0.65 meters**

**Step 5 — Add wastage (~10–15%):**

> 0.65 × 1.15 = **~0.75 meters per T-shirt** ✅

### 📝 Easy-to-Remember Notes

| Point | Explanation |

|-------|-------------|

| **Always add seam allowance** | Usually 1–2 cm per seam, or 5 cm total per panel |

| **Fabric width matters a lot** | Wider fabric = less length needed |

| **Add 10–15% wastage** | For cutting loss, pattern mismatch, defects |

| **More panels = more fabric** | Collars, pockets, cuffs all add up |

| **GSM doesn't affect meters** | But affects weight/cost calculation |

### 🧠 The Golden Rule to Remember:

> **Total Area of All Pieces ÷ Fabric Width = Fabric Length Needed**

> Then **add 10–15% for wastage.**
