Blog #1 - 🧶 Calculating Yarn Weight for Multiple Strands

If you’ve ever fallen in love with a too thin yarn for your project, don’t worry — holding multiple strands together is a great way to achieve the thickness you need. But how do you calculate the combined weight?

🔢 Step 1: Know the Weight or Yardage of Each Yarn

Check your yarn labels or listing info. You’ll want to know the yards (or meters) per 100g for each strand.

Example:

• Yarn A: 800 meters per 100g
• Yarn B: 1200 meters per 100g

🧮 Step 2: Use the Formula

Use this simple formula to estimate the combined thickness:

1 / (1 / A + 1 / B + 1 / C + …) = meters per 100g when held together

So if you’re combining two yarns:

1 / (1 / 800 + 1 / 1200) = approx. 480 m / 100g

This is roughly a DK or Light Worsted weight yarn.
