墙纸之家讯：一、近似计算方法：地面面积×3(3面墙)÷(墙布每卷平方数)+1(备用)=所需墙布的卷数
二、精确计算方法：所需墙布的总幅数÷单位卷墙布所能裁切的幅数=所需墙布的卷数。
1、所需墙布的总幅数=要粘贴墙布的长度÷墙布宽度；
2、单卷墙布所能裁切的幅数=墙布长度÷房间高度；
3、不同高度的墙布需要分开计算、汇总求各。
需要注意的是，不同的图案对墙布的用量会造成一定的影响，10%-20%的损耗是正常的。
◆Approximate Computing Method:floor area×3(3 walls)÷(the quantity of per roll of wall cloth,by square meter)+1(spare)=the quantity of required wall cloth,by roll.
◆Exact Computing Method:Total pieces of required wall cloth ÷Pieces can be cut one roll ＝Rolls of required wall cloth.
1.Total pieces of required wall cloth＝length of used wall÷width of wall cloth
2.Pieces can be cut one roll ＝length of wall cloth ÷height of room
3.Different height of walls should be counted individually,then adding together to make a summation.
Please note that different patterns will have certain influence to the use level of wall cloth.and 10%-20% of wastage is normal.
