即使是对手掌和足底表面的随意检查，也足以证明表皮隆起的宽度存在区域性差异。鞋底的脊线一般比手掌的脊线粗(Galton，1892)；不同区域的差异在手部和脚部都很明显，突出的区别是近端区域的脊部宽度增加。当不同个体的相应区域进行比较时，可以观察到男性的脊线往往比女性的更粗，在产前和出生后的生长过程中它们都变粗了，而且相同性别和体型的个体之间也有一些差异。奇怪的是，这些文献只包含了关于脊宽的随意陈述，通常是在这篇简短的介绍性评论中提出的，没有定量的数据。现有的最广泛的信息与脊线的生长有关：科利克(1848-1849)，科尔曼(1883)，A·F·赫克特(‘24)。这些作者的发现非常一致，赫克特的数字被引用为代表性数据。以下是单脊的平均宽度，仅在指尖模式中：3名早产儿0.15毫米；7名新生儿0.18毫米；然后，在不给出受试者数量的情况下，10年0.30-0.35毫米；成年女性0.40-0.50毫米；成年男性0.50毫米。值得注意的是，赫克特
Even a casual inspection of the palmar and plantar surfaces suffices to demonstrate that there are regional variations in the breadths of epidermal ridges. Ridges of the sole are generally coarser than those of the hand (Galton, 1892); variations in different regions are apparent in the hand and foot alike, the prominent distinction being increased ridge breadth in the proximal territories. When corresponding regions of different individuals are compared it is observed that ridges tend to be coarser in men than in women, that they coarsen in prenatal and postnatal growth, and that some differences occur among individuals of the same sex and body size. Curiously enough, the literature contains little more than casual statements on the subject of ridge breadth, most often presented as in this brief introductory comment without quantitative data.The most extensive available information relates to the growth of ridges: Kolliker (1848-1849), Kollmann (1883), A. F. Hecht ('24). The findings of these authors are in close agreement, and Hecht's figures are cited as representative. The following are average breadths of single ridges, in fingertip patterns alone: three premature infants 0.15 mm.; seven newborn infants 0.18 mm.; then, without giving the numbers of subjects involved, 10 years 0.30-0.35 mm.; adult women 0.40-0.50 mm.; adult men 0.50 mm. It will be noted that Hecht
