🧶 Yarn Count Converter
Convert a yarn count between tex, dtex, denier, the metric count (Nm), and the cotton count (Ne) — every pairing routes through a common tex base for a clean, consistent figure.
🧶 Convert Between Count Systems
What is a Yarn Count Converter?
Yarn fineness is described in a handful of competing systems, and a dye recipe or weaving plan often quotes one when your supplier lists another. This converter turns any value in tex, dtex, denier, Nm, or Ne into any of the others, so you can compare yarns, substitute a thread, and keep your numbers consistent across the whole project.
Direct systems measure weight per length; indirect systems measure length per weight — and routing everything through tex keeps the maths honest. The results are estimates for planning; test on a sample swatch first, since twist, moisture, and finish nudge real yarns away from the nominal count.
❓ Frequently Asked Questions
How does the yarn count converter work?
It converts everything through a common tex base. Direct systems scale linearly — dtex is tex × 10, denier is tex × 9 — while the indirect systems are reciprocals: the metric count Nm is 1000 ÷ tex and the cotton count Ne is 590.5 ÷ tex. Enter a value and pick the from and to units, and it does the round-trip through tex in one step.
What's the difference between direct and indirect yarn counts?
Direct systems (tex, dtex, denier) measure weight per unit length, so a higher number means a thicker, heavier yarn. Indirect systems (Nm, Ne) measure length per unit weight, so a higher number means a finer yarn. That's why converting between the two families flips the relationship — finer yarns get bigger Nm/Ne numbers but smaller tex/denier numbers.
Will the converted count match my yarn exactly?
These are estimates for planning; test on a sample swatch first. Real yarns vary with twist, moisture regain, and finish, and some cotton counts use slightly different constants, so confirm against the manufacturer's spec sheet before you order or substitute a yarn.
