How to Use the Yarn Calculator

A Yarn Calculator is a tool that helps knitters, crocheters, and weavers determine the estimated amount of yarn required for a specific project based on stitch density, project dimensions, and yarn usage per stitch.

Why Use a Yarn Calculator?

When planning a blanket, scarf, sweater, or any fiber-based project, it’s easy to underestimate or overbuy yarn. This tool ensures:

• You buy the right amount of yarn
• You avoid color mismatches from different dye lots
• You plan your project budget more accurately

Step-by-Step Guide to Using the Calculator

1. Enter the Width of Your Project

Type the desired width of your finished item in inches.

Example: A scarf might be 10, while a blanket could be 40.

---

2. Enter the Length of Your Project

This is the full height or length in inches.

Example: A blanket might be 60, or a shawl might be 70.

---

3. Enter the Stitch Gauge

This is the number of stitches per inch in both horizontal and vertical directions. You can find this by creating a swatch.

Example: 5 stitches per inch (measured by knitting or crocheting a 4×4 swatch and dividing).

---

4. Yards per Stitch

This is how much yarn each stitch uses, depending on your pattern and yarn thickness.

• Light yarn might be used 0.008 yards per stitch
• Thicker yarn might use up to 0.02

You can calculate this by making a swatch and dividing the used yarn by the number of stitches.

5. Click “Calculate Yarn Needed”

The calculator shows:

• Total stitches needed
• Total yarn required (in yards)

Use this value to buy the right number of skeins or balls.
