Textile sizing calculators
Count conversion, yarn diameter, warp weight and size pick-up, worked out in the browser. Then send us a construction and our technical team will come back with a recommended recipe.
Yarn count conversion
Ne = 590.54 / Tex · Nm = 1000 / Tex · Den = Tex × 9 · dTex = Tex × 10
Every conversion routes through Tex, so the set stays self-consistent in both directions.
Yarn diameter
d = 1 / (28 × √Ne)
Converted to Ne first. The formula is defined on English cotton count.
Returns inches, which is what the formula is defined in. The millimetre figure is the same number converted.
Weight of unsized yarn
w = (length × ends) / (1693.3 × Ne)
1693.3 is metres per kilogram at Ne 1, so length goes in as metres and the answer comes out in kilograms.
Size pick-up
net = sized beam − tare · add-on = net − unsized · pick-up = add-on / unsized × 100
Both of the methods in common use are shown. They are arithmetically the same and should always agree. If they do not, one of the weights going in is wrong.
RECIPE CALCULATOR
Send us the construction, get a recipe back
A size recipe depends on the yarn, the construction, the machine and what you are already running, so it is not something a page can work out on its own. Fill this in and our technical team comes back with a recommended recipe and dosage within 48 hours on working days.
NOT SURE WHERE TO START
Send us a beam that is giving you trouble
If warp breaks or loom stops are the problem, describe what you are seeing and we will work back to the sizing.
