Whether it fits comes down to the measurements most people skip.

Measure smart

What to measure.

Four numbers decide nearly every fit check. Get these right and the rest follows.

  1. 01转角旋转计算:沙发长度 × 深度共同决定所需的最小走廊宽度——更长更深的沙发两侧都需要更宽的走廊
  2. 02旋转点处的内侧墙壁通过空间——这是转弯时沙发中段最贴近墙壁的地方
  3. 03外侧墙壁通过空间——沙发两端在旋转时向外摆动,如果走廊狭窄可能撞到远侧墙壁
  4. 04是否备有家具滑垫——它们在集中压力造成损坏的旋转点保护墙壁和地板

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

  1. ⚠只测量一条走廊的宽度——不对称走廊在老建筑中很常见,较窄的一侧决定旋转
  2. ⚠计算旋转空间时忽略沙发深度——在相同长度下,36" 深的沙发比 30" 深的需要明显更宽的走廊
  3. ⚠以为转角处平搬就行——大多数 90° 转弯需要把沙发竖向倾斜或以陡峭角度斜着通过
  4. ⚠未在旋转点保护墙壁——转角承受所有接触压力,石膏板墙面在 100 磅以上沙发边缘下很容易凹陷

Frequently asked

Questions we keep getting.

  • 把沙发绕过转角需要多宽的走廊?

    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

  • 什么是“移动沙发问题”?

    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

  • 我可以把沙发竖向旋转以通过转角吗?

    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

  • 如果我的转角是圆角而非直角怎么办?

    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。
