主管「陽」事之魯班尺上尺文公尺的部分，「有字」的寬度代表對陽間生者吉祥之意。在本研究的下圖中顯示：以「陽」也有字為測量在一開始並未被使用在墓碑上。然而，隨著造墓在澎湖與台灣的專業化和商業化，能提供陽也有字的刻墓師比起無法提供者較有競爭力。這樣的結果造成今日的墓大多也關注陽也有字的做法。有趣的是，數據顯示在造墓時關注陽也有字的議題上，澎湖商業化比起台灣更早。這樣的假設我們將試圖在未來的研究中校驗。

陽, the upper part of the modern Luban defines the good measures for the living. As our data show, this measure hasn’t originally been used to define the measures of tombstones. However, with the professionalization and commercialization of the tombstone production on Penghu and Taiwan, its seems that those carvers who applied also the 陽 measures had a competitive edge over carvers who didn’t, resulting today in an almost complete domination of this practice. Interestingly, the data seem to suggest that the commercialization on Penghu preceded that on Taiwan, a hypothesis we will try to verify in later research.
