Abstract: This paper attempts to investigate how differences of height, education and age within a couple influence evaluation about partner. Further, this paper explore the effect of differences changed before and after marriage. For this purpose, monthly web-site surveys were conducted to collect the individual level data of unmarried persons who having plan to get married with boy/girl friends. Based on the collected data covering the period from March 2012 to March 2015, through the Panel data analysis, we found as; (1) gaps of height and education reduced quarrel with partner after the marriage. (2) Further, quarrel lowered the evaluation about the partner. Hence, there is indirect positive effect through quarrel on evaluation about partners. (3) However, after controlling the indirect effect through quarrel, gaps of height and education lowered the evaluation about partner which is considered as the direct negative effect on the evaluation. (4) considering these results jointly indicated that effect of 1 year difference of education on the evaluation is equivalent to that of 4.27 cm difference of height. Assuming that gap of height and education enhanced division of labor within a household, combined results implied that the division of labor reduce interaction between wife and husband and so avoid the quarrel. This in turn improve evaluation about partner. However, reduction in interaction between husband and wife increased psychological distance between them, resulting in lowering the evaluation about the partner. The negative effect of the gap on the evaluation is far larger than the positive one.
