When standing on both feet the mean height of the arch at the tangent to the medial plantar imprint is 5 mm at the age of 4 years. The "critical limit" is approx. 2 mm. The height of the medial longitudinal arch increases each year. The increase is greater at the age of three than at six years, and should be at least 1 mm between the third and fourth years of life. Girls have higher arches than boys of the same age. The medial longitudinal arch is lower in children with superextensible knee joints and hypermobile ankle joints. The talocalcaneonavicular joint becomes more mobile as the height of the medial longitudinal arch increases.
双脚站立时，4岁儿童足底内侧印记切线处足弓的平均高度为5毫米。“临界值”约为2毫米。内侧纵弓的高度逐年增加。三岁时的增加幅度大于六岁时，且在生命的第三年和第四年之间增加幅度应至少为1毫米。同龄女孩的足弓比男孩高。膝关节过度伸展和踝关节活动过度的儿童，其内侧纵弓较低。随着内侧纵弓高度的增加，距跟舟关节的活动度会增大。
