Yarn Calculator for Crochet
How much yarn do I need? Estimate by project — or upload your chart and get per-color yardage from real stitch counts.
Estimated yardage
≈ 3,000 yards
≈ 2,743 meters · ballpark for a throw blanket (50×60 in) in worsted
All numbers are estimates from standard stitch-gauge heuristics — yarn, tension, and stitch pattern shift real usage by ±20%. Always buy one extra skein. 💕
Running out of yarn mid-project means dye-lot roulette; overbuying means a stash that owns you. This calculator works two ways: a quick project-based estimator (blanket, scarf, sweater, amigurumi — pick a yarn weight, get a yardage ballpark), and something no lookup table can do — upload a photo or chart and it counts the actual stitches per color, then converts them to yards and skeins.
The chart mode uses the same engine as our pattern generator: your image is converted to a stitch grid, each color's stitches are counted exactly, and standard stitch-gauge heuristics turn counts into yardage. It's the closest you can get to weighing a finished piece before you start.
What you get
Two ways to estimate
Project-based ballpark for quick planning, or chart-based counts when you need per-color precision.
Per-color yardage from your chart
Upload a photo, get stitch counts per color converted to yards — and to skeins of your specific yarn.
Graphgan and C2C aware
Chart mode accounts for the difference between single-crochet stitches and C2C blocks when estimating usage.
Every yarn weight
Fingering to super bulky — finer yarns need more yardage for the same piece, and the math reflects that.
Skein conversion
Enter the yards per skein on your yarn label and get a shopping count, not just a yardage number.
Free, no sign-up
Both modes are free. Chart mode runs on the same generator engine as the rest of the site.
How to figure out how much yarn you need
Pick your estimation mode
Use "By project" for a fast ballpark, or "From your chart" to compute exact per-color stitch counts from a photo or chart image.
Set yarn weight and details
Choose your yarn weight — it changes yardage by ±40%. In chart mode, also set the grid and color count so the stitch counts match your plan.
Convert to skeins and buy one extra
Enter the yards per skein from your yarn label to get a skein count. Estimates run ±20% with tension, so always round up by one skein.
Calculator vs. the yarn-label guessing game
| Stitch-count estimation | Generic yardage tables | |
|---|---|---|
| Basis of the estimate | Your actual chart — stitches counted per color | Average projects that may look nothing like yours |
| Multi-color projects | Yardage split per color, so you don't overbuy the accent shade | One total number; the color split is your problem |
| Graphgan / C2C projects | Designed for them — that's what the stitch grid is | Tables rarely cover pixel blankets at all |
| Accuracy | ±20% with swatch-verified heuristics | Often ±50% on unusual projects |
Frequently asked questions
How much yarn do I need for a crochet blanket?
In worsted weight: about 1,000–1,200 yards for a baby blanket (30×36 in), 2,800–3,500 for a throw (50×60 in), and 6,000+ for a queen. Bulky yarn needs roughly 40% less yardage; DK about 10% more. Use the project tab above for your exact combination.
How is yarn yardage calculated from a crochet chart?
Each chart cell is one stitch (or one C2C block). The calculator counts cells per color, then multiplies by the yarn a stitch uses at your yarn weight — about 0.06 yards per single crochet in worsted, 0.65 yards per C2C block. The result is per-color yardage, which converts directly into skeins.
How many skeins of yarn for a graphgan?
It depends entirely on the design's color distribution, which is exactly what the chart mode computes: upload your image, and each color's stitch count becomes yards. A 60×60 worsted graphgan typically uses 2,000–2,500 yards total, split across the palette — often one skein of accent colors and several of the background.
Does crochet use more yarn than knitting?
Yes — crochet typically uses about 25–30% more yarn than knitting for the same fabric area, because crochet stitches are thicker and more three-dimensional. Dense stitches like single crochet use the most; lacy, open patterns use the least.
How accurate are yarn estimates?
Expect ±20% from any calculator: personal tension, hook size, stitch pattern, and even humidity shift real usage. Swatch a 10×10 cm square, weigh it, and scale by your project's area for the gold-standard check — and always buy one extra skein in the same dye lot.
Is this yarn calculator free?
Yes — both the project estimator and the chart-based mode are free with no sign-up.
