Pleats determined by quantity: two and a half times the window width

A side-by-side comparison of two curtains, with emphasis on the drape. The left side is high-spec: heavy fabric, ample material—width is two and a half times the window width, thus forming dense, deep, and regular vertical pleats when drawn, with consistent depth for each pleat; the hem is weighted with lead tape and extends a few centimeters to pool on the floor; the track is hidden in a ceiling recess, with the fabric hanging directly from the highest point without visible hardware. The right side is standard: light fabric, material only one and a half times the window width, resulting in sparse, shallow, and inconsistent pleats; the hem is just off the floor and flares outwards; the curtain rod is exposed. The fabric color is the same for both. Avoid: making the two versions similar, replacing material quantity differences with color and material differences, depicting the high-spec hem as off the floor, exposing the track of the high-spec version.

兩片窗簾的並置對照,重點在垂墜。左側是高規格的:布料重、用量足——寬度是窗寬的兩倍半,因此拉開時形成密集、深而規律的縱向褶,每一褶的深度一致;下擺加了鉛帶配重並多出幾公分堆在地上;軌道藏在天花凹槽內,布從最高處直接垂下沒有可見五金。右側是一般的:布輕、用量僅窗寬的一點五倍,褶稀疏而淺、深度不一;下擺剛好離地並向外翻;窗簾桿外露。兩者的布料顏色相同。避免:讓兩者相似、用顏色與材質差異取代用量差異、把高規格的下擺畫成離地、露出高規格版本的軌道。
