地板计算器 — 估算所需瓷砖、木板 & 箱数
输入房间的长度和宽度，选择损耗系数（直铺 5%、标准 10%、斜铺 15%），并从产品标签输入每箱覆盖面积。计算器在净面积基础上加入损耗后向上取整到整箱，确保材料充足、不中途断货。

Found on the flooring box label — typical range is 15–25 sq ft
常见问题
地板计算器是如何工作的？
地板计算器根据房间的长宽尺寸计算所需地板面积。您可输入多个房间并将面积相加，计算器会在总面积基础上加上建议的余量（通常为 10%），并按您选择的地板规格计算所需箱数（盒数）。
我应该多订购多少地板？
建议多订购 10% 的余量用于切割损耗和将来的修补，斜铺或鱼骨铺法建议增加到 15%。余料最好保留以备日后更换损坏的地板块，因为同批次的地板色号可能会有细微差异。
如何计算不规则形状房间的地板用量？
将不规则房间分割成若干矩形区域，分别计算每个矩形的面积，然后相加得到总面积。本计算器支持输入多个区域面积并自动求和，再加上余量。
铺设地板需要什么材料？
除地板本身外，通常还需要：防潮膜或底垫（部分产品已内置）、踢脚线/收边条、门槛条（不同地板间的过渡条）、专用胶水（实木地板）或卡扣（浮动安装）。本计算器可提供辅材用量估算。
Flooring Calculator: Area, Waste & Boxes Guide
This flooring calculator estimates how much material you need to cover a room. Enter the room dimensions, a waste factor to account for cuts and offcuts, and the square footage per box printed on the product label. The result tells you the net area, total area to purchase, and how many boxes to add to your cart — rounded up so you never run short mid-project.
Flooring Area Formula
Step 1 — Net Room Area
Measure the longest and widest points of the room in feet, including any alcoves.
Step 2 — Add Waste Allowance
Total Area = Area + Waste
Waste covers cuts at walls, damaged pieces, and future repairs.
Step 3 — Boxes to Buy
Always rounded up to the nearest whole box — you cannot buy a partial box.
Waste Factor Guide
The right waste percentage depends on the layout pattern and room complexity. Use the table below as a starting point.
| Installation Pattern | Recommended Waste | Reason |
|---|---|---|
| Straight lay (parallel to walls) | 5% | Minimal cuts; offcuts often reused |
| Staggered / running bond | 10% | Standard recommendation for most planks and tiles |
| Diagonal (45°) | 15% | Large corner triangles create significant waste |
| Herringbone / chevron | 15–20% | Complex pattern; many angled cuts |
| Irregular / L-shaped room | 10–15% | Extra cuts at inside corners |
How to Measure Your Room Accurately
- Measure at the widest and longest points of the room — not between baseboards, but wall to wall.
- For L-shaped rooms, split into two rectangles, calculate each separately, and add the areas.
- Include closets and alcoves that will receive the same flooring.
- Round up fractional inches to the nearest half-foot to build in a small buffer.
- Check the box label for the exact coverage figure — it varies by plank width and tile size.
- For large open-plan spaces over 500 sq ft, consider adding an extra 2% on top of your waste factor.
Common Flooring Types & Box Coverages
Luxury Vinyl Plank (LVP)
Typically 18–25 sq ft per box. Water-resistant and suitable for kitchens and bathrooms. Allow 10% waste for straight lay.
Ceramic & Porcelain Tile
Box coverage varies widely by tile size — small 4″ tiles may cover 10 sq ft, while 24″ large-format tiles can cover 16–20 sq ft. Always check the box. Allow 10–15% waste.
Hardwood & Engineered Wood
Typically 15–25 sq ft per box depending on plank width. Allow 10% for straight lay and 15% for diagonal or herringbone patterns.
Laminate
Usually 20–30 sq ft per box. Quick to install and budget-friendly. Standard 10% waste applies; avoid for wet areas.
