How Many Yards Is 100 Grams of Worsted Weight?

Roughly 200-220 yards is common for a standard 100-gram worsted-weight skein, though the honest range across real worsted-weight yarns runs wider than that — some skeins hold notably less, others notably more, depending on fibre and spin.

Why "worsted weight" alone doesn't pin down an exact yardage

The CYC weight category describes a gauge range, not a fixed yards-per-gram figure — a dense fibre like cotton packs more mass into the same worked thickness than a lofty wool does, so two yarns correctly labeled "worsted" can differ genuinely in actual yards per 100 grams even at a comparable gauge.

Why the label always beats this estimate

The 200-220 range above is useful for a rough, before-you-have-yarn estimate, but once you're holding an actual skein, its own printed yardage is the number to use — checking the label takes seconds and removes the guesswork this estimate can't fully resolve.

What this means for buying yarn to match a project's yardage need

If a pattern or calculator gives you a target yardage, divide by your specific skein's own stated yards-per-100-grams (not the 200-220 estimate above) to get an accurate skein count — using the rough estimate instead of your actual yarn's real number is a common, avoidable source of buying too few or too many skeins.

FAQ

Does fibre blend (like a wool-acrylic mix) predictably shift this number? Somewhat, though not in a single fixed direction — a blend's density depends on the specific ratio and how the fibres are spun together, which is exactly why checking the specific yarn's label matters more than trying to predict from blend composition alone.

Is DK weight's yards-per-100-grams meaningfully higher than worsted's? Yes, generally — DK's finer strand typically yields more yardage per 100 grams than worsted's thicker strand does, consistent with DK sitting one category finer overall.

Should I round up or down when converting a calculated yardage need into whole skeins? Always round up — a fractional skein isn't purchasable, and rounding down risks a genuine shortfall partway through a project.

Is 100 grams the most common put-up size for worsted-weight yarn? Very common, though 50-gram, 150-gram, and 200-gram (or larger) put-ups all exist too — always check the specific skein's own stated weight rather than assuming 100 grams by default.

Does hand-dyed worsted-weight yarn tend to differ in yardage from mass-produced skeins? Not inherently from the dyeing process itself, but hand-dyed yarn is more likely to come from smaller, less standardized spinning batches, which can mean more skein-to-skein variation in actual yardage than a large commercial mill typically produces.
