School Uniform Fabric GSM Guide: 120GSM vs 160GSM for Retailers

## What Is GSM and Why Does It Matter for School Uniforms?

GSM stands for **Grams Per Square Metre** — it measures the weight and density of fabric. For school uniforms, GSM is one of the most important quality indicators. Higher GSM generally means:
- Thicker, more durable fabric
- Better shape retention after washing
- Less pilling and wear over time
- Higher cost per unit

For wholesale dealers supplying school uniforms, understanding GSM helps you match the right product to your customer's expectations and budget.

## GSM Range for School Slacks and Uniform Bottoms

| GSM | Fabric Feel | Durability | Best For |
|-----|-------------|------------|----------|
| 100–120 GSM | Thin, lightweight | 1–2 years | Budget schools, one-time use |
| 140–160 GSM | Medium weight | 2–3 years | Most government and private schools |
| 170–200 GSM | Heavy, structured | 3–4 years | Premium schools, export quality |

**Our specification:** AR Hosiery's Selex school slacks use **180–200 GSM poly-viscose**. Industry ranges vary by supplier, so retailers should verify the stated specification against the delivered batch.

## Poly-Viscose vs Cotton-Polyester for School Slacks

### Poly-Viscose (Most Common)
- Composition: 65% Polyester, 35% Viscose
- GSM range: 120–200
- Look and feel: Close to formal trouser fabric, slight sheen
- Durability: Excellent — resists pilling and fraying
- Price (wholesale): ₹90–160/piece depending on GSM
- Best for: School slacks, formal uniform bottoms
- AR Hosiery School Slacks (Poly-Viscose)

### Cotton-Polyester (Budget Segment)
- Composition: 60% Cotton, 40% Polyester
- GSM range: 120–150
- Feel: Softer, more breathable, less formal
- Durability: 1.5–2 years average
- Price (wholesale): ₹70–120/piece
- Best for: Hot-climate schools, comfort-focused requirements

## What Schools Actually Specify

When schools issue uniform tenders or supply orders, they typically specify:
- Fabric type (poly-viscose preferred for formal wear)
- Minimum GSM (140 GSM is the most common requirement)
- Color (exact Pantone/RAL code for bottle green, navy, etc.)
- Size range (usually 22–40 for girls' slacks)
- Compliance certificate (IS:1300 or BIS for some tenders)

**Dealer tip:** Always ask the school for their specification sheet before ordering. Supplying 120 GSM to a school that requires 160 GSM leads to complaints and returns.

## Price vs GSM: What Retailers Should Stock

For most retailers serving mixed markets (budget + mid-range schools):

- **120 GSM stock:** 20% of total (budget schools, replacement orders)
- **140–160 GSM stock:** 65% of total (main product line)
- **180+ GSM stock:** 15% of total (premium segment, CBSE schools)

This split balances margin (higher GSM = higher margin) with volume (140–160 GSM has the widest market).

## How to Verify GSM Quality

When receiving a bulk shipment, you can do a quick field test:
1. Cut a 10cm × 10cm swatch of fabric
2. Weigh it on a precision scale (in grams)
3. Multiply the weight by 100 — this gives approximate GSM

A 10cm × 10cm piece weighing 1.6g = 160 GSM fabric. If it weighs only 1.2g, you received 120 GSM material despite ordering 160 GSM.

Always do this check on the first batch from any new supplier.
