Best Yarn for Knitting Sweaters in India (2026 Guide) – Why Vardhman Happy Knit Works Perfectly

How Many Balls of Yarn Do You Need for a Sweater? (Happy Knit Guide)

Knitting a sweater is exciting, but one of the most common questions knitters ask is:
How many balls of yarn do you actually need to knit a sweater?

Buying too little yarn can stop your project midway, while buying too much can be wasteful. In this guide, we explain exact yarn quantity for sweaters using Vardhman Happy Knit 100g acrylic yarn, in a simple and beginner-friendly way.

Why Yarn Quantity Calculation Matters

Every sweater uses a different amount of yarn depending on size, stitch pattern, and yarn thickness. Many beginners underestimate yarn requirements and later struggle to match the same shade or dye lot.

Calculating yarn quantity correctly helps you:

• Avoid running out of yarn

• Maintain colour consistency

• Save money and time

• Knit stress-free

Factors That Affect Yarn Requirement for a Sweater

Before calculating yarn quantity, keep these factors in mind:

1. Sweater Size

Larger sweaters obviously need more yarn than smaller sizes.

2. Yarn Weight

This guide is based on 100g acrylic yarn like Happy Knit.

3. Needle Size & Stitch Pattern

• Tight stitches → more yarn

• Loose stitches → less yarn

• Ribbing and cables consume more yarn

4. Sleeve Length

Full-sleeve sweaters require more yarn than sleeveless or half-sleeve designs.
