Yarn Weight Standards

Here in North America, the yarn companies come together as a collection to work together voluntarily with the Yarn Craft Council of America. You will see standard information that appears on the ball bands of companies who cooperate to make the labels easier for consumers to use.

Balls bands have logos on the ball to indicate the weight of the yarn. This allows consumers to be able to mix and match yarns together when the classification of weight is the same.

Keep in mind there is generally a tolerance of yarn that falls in weight classes and it can vary. In 2015, the Yarn Craft Council introduced Jumbo 7 as a new option due to the latest new yarns being extremely chunky.

Mikey, aka Michael Sellick, of The Crochet Crowd, started this online journey back in 2008. A mere hobby in trying to reach out to others as he was mentally struggling with his own issues. His goal was simple, find others in the yarn communities, like him, that have a common interest.

The journey and main baby of the whole idea started with a YouTube Channel and then in 2011, an official website was developed. Michael is not only the face of The Crochet Crowd but also the working engine behind the crowd in self-taught programming, social media and so much more.

Enjoy the stitching journey. Life is short, enjoy this wonderful hobby and all of the learning opportunities that come with it.

    Hi Mikey, thank you for this article on yarn weights, but please, can I ask you to mention the weight of the yarns you use in your demonstrations? As a UK crocheter I don’t always recognise the yarn and have to guess the weight from the size of hook you’re using.
    I love the Crochet Crowd and constantly have something on the hook!
    Best wishes,
    Debbie.
