# 瓷砖损耗系数：按铺贴方式该多订多少（附对照表）

直铺、错缝、斜铺、人字形与大规格铺贴的损耗百分比，加上色批与备砖——让你第一次就买对。

## 1\. 为什么要多订

每种铺贴都会产生损耗：切边、破损、钻孔失误，以及将来维修要用的砖。北美瓷砖协会（TCNA）估计，正常搬运下仅陶瓷砖破损就有 2–5%。干到一半没砖了，意味着再付一次运费，更糟的是补来的可能不是同一色批，和已铺上的对不上。

## 2\. 按铺贴方式的损耗：对照表

| 铺贴方式 | 损耗 |
| --- | --- |
| Straight lay | 5–10% |
| Offset / brick | 7–10% |
| Diagonal 45° | 10–15% |
| Herringbone | 12–25% (18% typical) |
| Large-format ≥12×24 | add ~2% |
| Large-format 24×48 | up to 20% |
| Natural stone | 10–15% |

小房间和不规则的墙面会把每一个数字推向其区间的上限。

## 3\. 大规格的特殊之处

大规格会改变算法。一块 24×48 砖破损，就是一次性报废好几个平方英尺，剩下的小边角又短得无法再用。地漏、插座、门口门槛这些障碍，比开阔地面每平方米多出更多切割。如果房间既用大砖又有很多障碍，按接近 20% 计划，下单前先实地排版验证。

## 4\. 色批与备砖

色差按 V1（均匀）到 V4（差异明显）分级——即使同一型号，不同生产批次之间颜色也会漂移。所有箱子一次下单并同一批号，完工后仍留 5–10% 备砖：瓷砖型号停产很快，五年后一片能对上的备砖，远比这点储藏空间值钱。

## 5\. 简单的工作流程

仔细量好房间，先选铺贴方式再下单，并在 [瓷砖计算器](https://nestingcalc.com/cn/tile-calculator/) 中套用该铺贴方式的预设损耗系数——它内置直铺、错缝、斜铺、人字形与大规格的百分比。结果向上取整到整箱，再留一箱未开封的砖干燥存放，供日后维修。这一箱，是装修行业里最便宜的保险。
