Yarn weight or thickness is typically classified into different categories, which can vary slightly depending on the source or country. The most commonly used system for categorizing yarn weight is the Craft Yarn Council's Standard Yarn Weight System. Here are the standard categories along with their approximate weights and recommended needle or hook sizes:
Lace: This is the finest and thinnest yarn category. It is used for delicate lace projects.
Approximate weight: Super fine or fingering weight
Recommended needle or hook size: 1.5 mm to 2.25 mm (US size 000 to 1)
Sock/Fingering: This category is commonly used for socks, lightweight garments, and delicate projects.
Approximate weight: Fine weight
Recommended needle or hook size: 2.25 mm to 3.25 mm (US size 1 to 3)
Sport: This category is used for lightweight garments and accessories.
Approximate weight: Light weight
Recommended needle or hook size: 3.25 mm to 3.75 mm (US size 3 to 5)
Worsted/Aran: This is a medium weight yarn category commonly used for a variety of projects, such as sweaters, blankets, and scarves.
Approximate weight: Medium weight
Recommended needle or hook size: 4.5 mm to 5.5 mm (US size 7 to 9)
Bulky: This category is used for quick projects and warm garments.
Approximate weight: Bulky weight
Recommended needle or hook size: 5.5 mm to 8 mm (US size 9 to 11)
Super Bulky: This is a very thick yarn category, often used for chunky scarves, blankets, and cozy accessories.

Please note that these are general guidelines, and yarn thickness can vary slightly between different manufacturers and specific yarn types. It's always a good idea to check the yarn label for specific information regarding weight, recommended needle or hook size, and gauge to ensure compatibility with your project.
