       钣金通常以量规进行测量，基于材料厚度和类型的重量测量。数字会因材料类型的不同而不同，并且随着薄板变薄而逐渐增大（锌薄板除外，这里不再讨论）。此处显示的是铝，钢，不锈钢和镀锌钢板的图表，厚度范围为1/64到1/4英寸。仪表号在较厚和较薄的部分都继续，但是这些图表涵盖了最常见的范围。这些图表包括小数，十进制和度量标准尺寸以供参考。

       铝规基于Brown and Sharpe（美国线规）标尺，而钢则基于制造商标准规标尺。英格兰的钢板被另一种量规系统覆盖。

计最初是为开发线图作为有可用于确定直径不准确的方法。通过逐渐变细的模具拉出导线，并为每个模具分配一个编号。随着拉线能力的增强，必须指定新的线规号。由于没有。1已经建立，没有。0（1个），00（2个）等等开始起作用。
