Textile & Fashion Suite
Streamline garment fitting, calculate pattern adjustments, and translate fabric weights and hardware standards used across global apparel manufacturing.
Button Size (Ligne ↔ mm ↔ inches)
Convert traditional ligne (L) measurements used in tailoring to millimeters and decimal/fractional inches, with relative size guides.
Understanding Ligne measurements
The Ligne (abbreviated as L) is an absolute unit of length equal to exactly 1/40 of an inch (0.635 mm) traditionally used by tailors and haberdasheries globally to measure button diameters.
