X-height



In the English system, the upper half of the x-height and the ascenders of the characters are more important and differentiated than from the lower half of the x-height and the descenders. For example, the lower part of the characters on the lower case of a, g, p and q are more differentiated. When the upper half of x-height are covered, it is really difficult to see the text. However, if the lower half is covered, it is still able to read the text.

In the traditional Chinese system, the roles of the upper and lower half are equally important because the characters were formed by different radicals and it can be mixed around and form a new or different character. Therefore, if half or any part of the character is covered, it may becomes another character and people may get confusion by that. Hence in traditional Chinese system, both the upper and lower half are important.
