eng.thread-count-fabric Calculator
Calculates fabric thread count (threads per inch in warp and weft) and GSM from yarn count and weave structure. Thread count above 400 in single-ply fabric requires very fine yarns — marketing claims of 800–1,000 TC often use multi-ply yarns, which are no softer than 400 TC single-ply.
Inputs
Warp Threads Per Inch
Reference formula or conversion factor shown for context.
Weft Threads Per Inch
Reference formula or conversion factor shown for context.
Ply
Reference formula or conversion factor shown for context.
Results
thread count (per in²)
Total number of items or occurrences.
effective single-thread TC
Sample size or count used in the calculation.
quality tier
A qualitative assessment of how the result compares to the desired standard or benchmark.
warp × weft
Reference formula or conversion factor shown for context.
ply
Reference formula or conversion factor shown for context.
note
Supplementary information explaining an assumption, caveat, or important context for interpreting the result.
