| All versions of self-similarity imply scale ambiguity: fractals have no natural size. | ||
| By contrast, Euclidean objects do have a natural size: circles and spheres have diameters, squares have side lengths, and so on. | ||
| So pictures of natural fractals often include Euclidean objects to set the scale. Lens caps are common in geology texts. | ||
