Proportions-modern-multiscript-fonts

Making similar letter proportions is an essential ingredient for designing single style multi-script fonts in one font style. Just like a chair and a table must share proportions to function well together. The x-height and the loop-height must be the same, as well as the space for ascenders and descenders. The difference between the loop-height and the tooth-height should be reduced. Also letter widths should be similar, either in shape or by letter spacing.
