Comparison of sizes of semiconductor manufacturing process nodes with some microscopic objects and visible light wavelengths. At this scale, the width of a human hair is about 10 times that of the image.^[1]

To help compare different orders of magnitude, this page lists lengths between 10⁻⁵ m and 10⁻⁴ m (10 µm and 100 µm).
