20 平方米的房间需要多少地板？

按 10% 损耗约需 22 平方米。计算器会根据你的板材规格换算成确切的箱数。

地板应该朝哪个方向铺？

平行于最长的墙，或顺着进门的视线方向。在木基层上还应与龙骨垂直，以获得足够刚度。

需要留伸缩缝吗？

需要，靠墙及固定物处留 6–12 毫米，由踢脚线遮盖。木地板和强化板会随湿度伸缩，铺死会起拱。

什么是适应期，有必要吗？

把地板在安装房间内放置 48–72 小时，让含水率与环境一致。实木若省略这一步，冬天会开缝、夏天会翘边。

基层平整度要求多高？

多数锁扣产品要求 3 米内偏差不超过 5 毫米。锁扣在鼓包和凹陷处会失效，几个月后表现为接缝开裂。

公式

板数 = 向上取整(面积 × (1 + 损耗) ÷ 单板面积)

参考资料

Measure what the tool asks for
This calculator works from 地面面积 in ft², 板材宽度 in in and 板材长度 in in. Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
板数 = 向上取整(面积 × (1 + 损耗) ÷ 单板面积) Every figure on the page comes out of that one expression, so you can check it by hand.
Why it adds 10% waste
NWFA 建议直铺 5%、错缝 10%、斜铺 15%。
Where the numbers come from
The constants are taken from NWFA — National Wood Flooring Association installation guidelines, ASTM F710 — Preparing Concrete Floors to Receive Resilient Flooring and MFMA — Maple Flooring Manufacturers Association technical resources, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.

常见问题

常规铺法 10%，斜铺 15%。另外建议多买同批次一箱备用，不同批次之间色差明显。
