Best projects and how much yarn you need

Choose bulky yarn for quick blankets, chunky hats and cowls, rugs, baskets and plush toys. Because each stitch is large, a blanket in this weight can be finished in a few evenings.

With the average ball of this group (161 m), a 1,100 m throw blanket needs about 7 balls and a 220 m hat about 2 balls. For an exact figure for your pattern, size and stitch, use the yarn calculator.

How to choose and substitute

Compare yarns by meters per 100 g rather than by brand or ball weight: two yarns within about 10 % of each other in density, with overlapping hook ranges, usually give the same fabric. Sort the table by density or hook size to find close matches quickly.

Before swapping yarns in a pattern, convert the number of balls by total length, buy every ball from the same dye lot and work a 12 × 12 cm swatch. Our side-by-side comparisons below show the exact ball conversion and a technical verdict for the most searched pairs.

Frequently asked questions

What hook do I need for chunky yarn?

The Craft Yarn Council recommends 6.5–9 mm hooks for bulky (CYC 5) yarn. Chenille and velvet yarns often look better with a hook at the smaller end of the range so the stitches stay defined.

How many Bulky / chunky yarns (CYC 5) does CrochetMetrics compare?

Our database currently lists 8 Bulky / chunky yarns (CYC 5) with verified ball band data, from 86 to 155 m per 100 g. Every yarn links to its own data sheet with substitutes and a ball converter.

Can I swap one yarn of this group for another?

Usually yes, if their meters per 100 g are within about 10 % and the hook ranges overlap. Convert the number of balls by total length, not by weight, and always check your gauge with a swatch before starting.
