What weight is red heart with love wool?

When it comes to knitting or crocheting projects using red heart with love yarn, one of the most common questions is: what weight is this yarn? Red Heart with Love is a popular medium worsted weight yarn that works up beautifully for a wide range of knit and crochet patterns. Understanding the weight system for yarn can help knitters and crocheters select the right yarn for their projects.

What Does Yarn Weight Mean?

Yarn weight refers to the thickness or size of a yarn fiber. It is measured in ‘ply’ which refers to the number of strands twisted together to create the finished yarn. The ply measurement ranges from lace weight (single ply) up to super bulky or ‘roving’ (multiple thick plies).

Standard yarn weights used for knitting and crochet include:

  • Lace
  • Super Fine
  • Fine
  • Light
  • Medium
  • Bulky
  • Super Bulky

Yarn weight gives an indication of how thick or thin the yarn is. Thicker yarns like bulky or super bulky work up faster and create a looser drape, while thinner yarns like lace or fine require more stitches and create a tighter fabric. Matching the yarn weight to the right knitting or crochet pattern is important.

How is Yarn Weight Categorized?

To standardize yarn weights across different brands and types of yarn, a numbering system is used. The yarn weight numbers range from 0 (finest) to 6 (heaviest). The numbers indicate the ply of the yarn fiber:

Yarn Weight Ply Knitting Gauge* Crochet Gauge*
Lace 1 33-40 sts 32-42 sc
Super Fine 1-2 27-32 sts 21-31 sc
Fine 2-3 23-26 sts 16-20 sc
Light 3-4 21-24 sts 12-17 sc
Medium 4 16-20 sts 11-14 sc
Bulky 5+ 12-15 sts 8-11 sc
Super Bulky 6+ 7-11 sts 5-9 sc

*Gauge is given over 4 inches/10 cm in stockinette stitch for knitting and single crochet for crochet.

This numbering system allows you to compare different brands of yarn and select the right weight for knitting or crochet patterns. The higher the number, the thicker the yarn.
