If we change that interval of white space without changing anything else, this doesn't add up any more. Or more accurately, it adds up to something we didn't want, if we had hoped to keep a consistent darkness. The proportion of black and white has changed, and that is where we get our sense of light and dark, not from the measure of any single element...So when we just put the weights and spaces where they look right, we create a relationship that is neither arithmetic nor geometric but somewhere between. Our eyes are perpetually tough customers, and rarely accept the simplest solution...Weight will crowd together according to the angle of intersection, with the problem getting more acute as the angle gets more acute. It's why type designers will take a deep breath before starting a Compressed Extra Bold version of something, or why they might openly swear at the capital W.
