One of the most common questions knitters and crocheters ask—whether they’re planning a cozy hat or a full-sized throw—is “How much yarn will I need?” The answer depends on several factors: the weight of your yarn, the size of your project, and even your tension or stitch choice.
To make it easy, I’ve put together a general guide for four popular projects—a hat, scarf, baby blanket, and throw—across five standard yarn weights: Fingering, Sport, DK, Worsted, and Bulky.
Use this as a planning guide before you shop or dive into your stash!
🧢Hat
| Yarn Weight | Grams | Yards | Meters |
| Fingering | 80–120 g | 320–420 yd | 290–385 m |
| Sport | 100–130 g | 280–360 yd | 255–330 m |
| DK | 100–150 g | 220–330 yd | 200–300 m |
| Worsted | 80–120 g | 180–250 yd | 165–230 m |
| Bulky | 100–150 g | 100–150 yd | 90–140 m |
Tip: Add a little extra if you want a folded brim or pom-pom.
Scarf
| Yarn Weight | Grams | Yards | Meters |
| Fingering | 250–400 g | 900–1,500 yd | 820–1,370 m |
| Sport | 250–350 g | 800–1,200 yd | 730–1,100 m |
| DK | 300–400 g | 660–880 yd | 600–800 m |
| Worsted | 250–350 g | 600–800 yd | 550–730 m |
| Bulky | 300–400 g | 400–600 yd | 365–550 m |
Tip: For infinity scarves or cowls, you can reduce these amounts slightly.
Baby Blanket
| Yarn Weight | Grams | Yards | Meters |
| Fingering | 500–700 g | 1,800–2,400 yd | 1,650–2,200 m |
| Sport | 500–700 g | 1,500–2,000 yd | 1,370–1,830 m |
| DK | 400–800 g | 875–1,750 yd | 800–1,600 m |
| Worsted | 400–700 g | 800–1,400 yd | 730–1,280 m |
| Bulky | 600–900 g | 600–1,000 yd | 550–915 m |
Tip: DK or worsted weight yarns are ideal for softness and warmth without being too heavy.
| Yarn Weight | Grams | Yards | Meters |
| Fingering | 1,000–1,400 g | 3,800–5,000 yd | 3,475–4,570 m |
| Sport | 1,000–1,300 g | 3,200–4,300 yd | 2,925–3,935 m |
| DK | 900–1,500 g | 2,000–3,300 yd | 1,800–3,000 m |
| Worsted | 800–1,400 g | 1,600–2,800 yd | 1,465–2,560 m |
| Bulky | 1,200–1,800 g | 1,000–1,800 yd | 915–1,650 m |
Tip: Bulky yarns work up fast and make gorgeously squishy throws—perfect for last-minute gifts.
Final Thoughts
These numbers are estimates, of course—your exact yardage will vary depending on your stitch pattern, hook or needle size, and personal tension. Lace, cables, and textured stitches all use more yarn than plain stockinette or single crochet.
When in doubt, buy one extra skein. It’s far better to have a little leftover yarn than to run short right before your bind-off!
