Unverified窗帘褶皱比（面料宽度/成品宽度）建议2.0倍，即2米窗做4米布，褶皱才饱满；预算有限可用1.8倍，低于1.5倍会显得平贴廉价没有垂坠感96% similarUnverified窗帘布用量按窗宽×2到2.5倍褶皱计算（褶皱比越大越显高档也越挡光），2倍是入门，2.5倍效果饱满；测量宽度应量窗帘杆/轨道长度而非窗户本身92% similarUnverified窗帘宽度需按窗框实际宽度乘以褶皱倍数计算：轻薄褶皱1.8-2倍，普通2倍，高级饱满感2.5倍；高度需在窗框顶部上方15-20cm安装并落地或离地1cm防漏光91% similarUnverified褶皱倍数（布料宽度/窗户宽度）建议2.0-2.5倍才饱满立体，1.5倍显稀疏塌陷。全遮光效果还依赖侧边遮光：安装时窗帘应比窗户每侧宽出15-20cm，顶部用轨道盒或加高安装避免漏光91% similarUnverified窗帘宽度=窗户/轨道宽度×2（褶皱倍数2.0）才有饱满垂坠感，1.5倍偏平，低于1.5倍拉开后布料稀疏还会漏光，测量时算的是成品宽而非布料展开宽90% similar
