输入你的沙发尺寸和走廊转角测量数据——应用会计算你能否旋转绕过转弯。
Whether it fits depends on measurements most people get wrong.
沙发长度和深度对比转弯处的走廊宽度
Item: 标准三座沙发:84" 长 × 35" 宽 × 33" 高
Space: 标准走廊转角:每侧 42–48" 宽。建筑规范最低标准:每条走廊 36"
Actual clear openings are usually 1–2″ smaller than the labeled size.
Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.
Verdicts are calculated by comparing all 6 item orientations against the space dimensions using verified building code standards. See our methodology

Frequently asked
对于标准 84 英寸沙发,平面旋转通常需要两条走廊都至少 42 英寸。如果一条走廊更窄,把沙发竖向倾斜以减少占地面积。走廊越宽,转弯越容易。
01移动沙发问题是一个著名的数学难题,研究能通过 L 形走廊转角的最大形状。实际操作中,答案取决于你具体的沙发尺寸和走廊宽度。我们的计算器能处理这个问题的现实版本。
02可以——把沙发竖立起来能大幅减少转弯所需的地面空间。84" 长、35" 宽的沙发竖立时仅占据 35" × 33" 的占地面积。84" 的长度需要天花板净空,但转角旋转会容易得多。
03圆角或斜切角比尖锐的 90° 角更容易通过。弧形墙壁起到沙发导轨的作用。测量弧度半径以及两侧的走廊宽度。
