Unverified购买前须测量门洞净宽并让帘宽为门洞的1.5-2倍以保证褶皱垂感，帘宽等于门洞宽会显得干瘪且遮挡不严89% similarUnverified尺寸选购：帘宽应为窗框（或轨道）宽度的1.8-2倍以保证褶皱饱满和两侧遮光，1.5倍以下拉平后漏光且显廉价；帘长落地款建议离地1-2cm，飘窗内嵌款需精确测量避免拖地积灰88% similarUnverified选购时门帘尺寸应比实际门洞宽3-5cm、高2-3cm，留出重叠余量保证闭合，尺寸买小会导致边缘漏缝87% similarUnverified窗帘褶皱比（用料宽度/杆长）建议2.0-2.5倍才能保证挂起后波浪饱满和遮光无缝隙，1.5倍属于低配偷工，商家标注的成品宽度需除以褶皱比才是实际覆盖窗宽87% similarUnverified定制遮光帘的帘高应量到地面留2cm左右（拖地款可+3cm），帘宽=窗宽×褶皱倍率（2.0倍最佳，1.5倍最低），褶皱倍率不足会导致平铺无褶且漏光86% similar
