摘　　要：房产面积的测算,在很多情况下采用设计图纸上的尺寸进行相应的计算。但由于施工控制网误差、放样误差、施工误差等的综合影响,导致了实际房子的尺寸与设计的理论数据有差异,从而使得算得的房产面积与实际的不符。这种差异或者说误差能达到什么样的数量级?对面积计算的影响有多大?本文分析了这些差异即误差的一般规律,对依据设计数据所计算的房产面积精度进行了探讨。Real estate area computation,in many situations,was used by the size on design paper to commutate.But with the weakness of construction control network error,lofting error,and construction error,the difference between the practical size and the design theoretical data has caused in practical work,and made it discrepant between calculation area and practical area.What are the magnitudes of these differences（errors）？ And what are the influences for area calculation？ In this paper,some general regulations of these errors are analyzed,and the real east area precision calculation that based on design data is discussed.
