Popular Yarn Sizers & Specific Guides
Dedicated calculator models for specific yarn weights and popular craft projects
Worsted weight (#4 Medium) is the most widely used yarn in the world. It averages roughly 2.0 yards per gram (200 yards per 100g skein). Weigh your leftover ball to find exact yardage.
Fingering weight (#1 Super Fine) yarn averages 4.0 to 4.4 yards per gram (approx. 400–440 yards per 100g skein). Calculate how much yarn remains in your sock yarn scraps.
DK weight (#3 Light) yarn is popular for garments and baby items, averaging 2.5 to 2.8 yards per gram (~260 yards per 100g). Weigh your mystery stash below.
Bulky yarn (#5 Chunky) works up fast, averaging roughly 1.1 to 1.3 yards per gram (~120–130 yards per 100g skein). Calculate your remaining yardage below.
A standard baby blanket measures 30" × 36" (or 36" × 36"). Calculate the exact number of skeins you need so you never run out of matching dye lots.
The 48" × 60" throw blanket is the most common couch afghan size. Sizing depends heavily on whether you choose single crochet (dense) or double crochet (open).
Classic granny squares create a breathable, lightweight fabric that uses approximately 15% less yarn than solid single crochet. Calculate your total yarn needs.
Corner-to-Corner (C2C) pixel blankets use block clusters of 3 double crochets. They create a plush, thicker fabric that requires slightly more yarn than standard rows.
Bernat Blanket Yarn is a #6 Super Bulky chenille yarn that comes in massive 300g / 10.5 oz balls (220 yards each). Calculate how many big balls to buy.
100 grams is the standard universal skein weight. However, 100g of lace yarn contains 800+ yards, while 100g of super bulky contains only 75 yards! See exact conversions.
Jumbo one-pound skeins (16 oz / 454 grams) are beloved for large afghans and sweaters. In worsted weight, a one-pound skein contains roughly 800 to 1,020 yards.
Never wonder if you have enough leftover yarn to make a matching winter hat. Most adult beanies require between 130 and 180 yards of worsted weight yarn.
Craft Yarn Council (CYC) Standard Weight Benchmarks
Universal fiber standards defining wraps per inch (WPI), average yardage per 100 grams, and recommended needles/hooks.

Frequently Asked Questions
How do you calculate yarn yardage by weight?▼
Weigh your yarn ball or scrap in grams on a digital kitchen scale. Then multiply the weight by the standard yards-per-gram ratio for that yarn weight category (for example, Worsted weight averages ~2.0 yards per gram, while Fingering sock yarn averages ~4.2 yards per gram).
How many yards of yarn are in 100 grams?▼
It depends entirely on the yarn weight thickness: 100g of #1 Fingering yields ~400–440 yards; 100g of #3 DK yields ~250–280 yards; 100g of #4 Worsted yields ~190–220 yards; and 100g of #6 Super Bulky yields only ~70–85 yards.
Can I calculate yardage if I still have the original ball band label?▼
Yes! Toggle to "From Ball Band Label" in our calculator. Enter the full skein grams and full skein yards printed on the label, then slide to your remaining scale weight. The calculator computes the exact proportional yardage remaining.
How many skeins of yarn do I need to crochet a throw blanket?▼
A standard 48" × 60" couch throw blanket requires roughly 1,800 to 2,200 yards of worsted weight yarn (about 9 to 11 standard 100g skeins). Use our dedicated Crochet Blanket Sizer to calculate exact requirements based on your chosen stitch pattern.
