A Simple Guide to Choosing the Right Yarn Thickness
Choosing yarn can feel overwhelming when you’re new to crochet.
Yarn labels show numbers, names, and symbols — and beginners often ask:
“Which yarn should I actually start with?”
In this guide, you’ll learn what yarn weight means, which yarn weights are best for beginners, and how to avoid common beginner mistakes.
What Does “Yarn Weight” Mean?
Yarn weight does not mean how heavy the yarn feels.
It refers to the thickness of the yarn strand.
Thicker yarn = larger stitches
Thinner yarn = smaller stitches
Understanding yarn weight makes learning crochet much easier.

Best Yarn Weight for Beginners (Short Answer)
👉 Worsted Weight Yarn (Weight #4)
This is the best yarn weight for beginners.
Why Worsted Weight (#4) Is Best for Beginners
Worsted weight yarn is ideal because it:
- Makes stitches easy to see
- Works with common hook sizes (5.0–5.5 mm)
- Is widely available
- Works for many beginner projects
Most beginner tutorials and patterns assume you’re using worsted weight yarn.
Can Beginners Use Bulky Yarn?
Yes — with some caution.
Bulky yarn (Weight #5) is good if:
- You want fast results
- You struggle to see stitches
- You prefer larger movements
Downsides:
- Less stitch definition
- Fewer pattern options
Bulky yarn is great for practice, but worsted is better for learning fundamentals.
Yarn Weights Beginners Should Avoid
Avoid these yarn weights at the beginning:
❌ Lace (0)
❌ Fingering (1)
❌ Very thin cotton thread
They make stitches hard to see and slow learning.
How to Find Yarn Weight on the Label
Look for:
- A number inside a yarn symbol (usually a skein icon)
- Text like “Worsted”, “Medium”, or “#4”
Yarn Weight vs Hook Size (Beginner Rule)
A simple beginner rule:
- Worsted (#4) → 5.0–5.5 mm hook
- Bulky (#5) → 6.0–8.0 mm hook
