Morphology
The meaning 'the thickness or breadth of a line' follows a straightforward noun–noun composition: 'width' (extent side to side) applied to 'line', yielding the measurement of a line's breadth. This is a common, cross-linguistic compositional pattern and, given context (drawing/printing/display), a B1 learner who knows both constituents will readily infer the intended meaning.
Etymology
Line width in science may come from the image of a bright line of color that becomes thicker when the source moves or is noisy, so the width shows how spread the light or sound is. That's why it means 'how much a spectral line is spread across different frequencies'.
