纸张的比例可以改变, 但最常用的纸张比例是 2:3. Tschichold 说 "For purposes of better comparison I have based his figure on a page proportion of 2:3, which Van de Graaf does not use."[6] 用这一原理文字区域和纸张具有相同的比例, 并且文字区域的高度等于纸张的宽度. 这一原理被Jan Tschichold在他的书书籍的形式(The Form of the Book)[1]被广泛推广. T
Robert Bringhurst 在他的书平面设计风格基础中声称: 这一比例可用于塑造页面以及塑造和定位文字区域. 这往往是中世纪图书需要的, 然而后来在文艺复兴时期, 排版采取更加均衡的页面并且文字区域的比例页有所不同.[7]
