The scaling of logs is the normal basis for transactions between loggers and sawmillers. Although not as accurate as the actual lumber tally after sawing, log scaling has certain advantages. It permits prompt ttlement for timber cut and delivered without waiting for actual yield, and it eliminates the need for parating logs on the yard by ownership.
Scaling practices may vary in local areas. Therefore, the practices should be agreed upon before sawlogs are sold. The standard methods for obtaining log measurements are:
原木检尺
原木检尺是砍伐者与锯木厂之间交易的基础，虽然检尺材积不可能跟锯切后实际材积完全一致，但采用原木检尺有必然的优势。它允许无须得出实际产出率即可快速砍伐并交货，且不需要根据原木所有人区分堆场上的原木。实际检尺方法在当地是多样化的。因此，实际检尺方法必须在将砍伐的原木卖出之前达成一致。标准的原木检尺方法如下：
Diameter
measured at the small end, inside the bark and to the nearest inch. For logs that are not round, average diameters should be taken. For example, a log measuring 10.0 inches in one direction across the diameter and 11.2 inches in another direction will average 10.6 inches. This would be scaled as an 11-inch log.
直径：按小头测量，扣树皮内测最大的直径，因为原木端头不是圆的，因此取平均直径。例如，一根原木的直径在一个方向测量为10英寸，在另一方向测量为11.2英寸，那我们将得出10.6的平均直径，结果则会标明11英寸。（以5舍6入为原则）。
Length
usually measured to an even number of feet such as 8, 10, 12, etc. If logs are cut to lengths between the even numbers, then the length is called to the smaller even number rather than to the nearest even number. For example, a log measuring 15 feet, 7 inches would be scaled as a 14-foot log rather than as a 16-foot log. In actual practice, about 3 inches additional length should be allowed. This will permit trimming the rough ends of boards sawed from the log.
长度：通常测量时会取偶数值，如8、10、12等等。如果原木被切断在偶数之间，长度通常会计量为小的偶数值而不会取最大值。例如，一根原木实际测量为15.7英尺，但是实际计量尺寸为14粉色英语怎么说英尺而不是16英尺。在实际测量中，长度可允许放宽3英寸，因为可允许将粗糙的那一端从原木上锯掉。一般而言，最少会有3英寸的余边长度。（如8英尺的码单长度，实际长度不可少于8英尺3寸）
Once the diameter and length have been measured, the log rule is ud to determine the board-foot volume. Since log rules are constructed on the basis of sound, straight logs and no allowance is made for defect, volume loss due to defect must be calculated parately and deducted from the gross scale given by the log rule. There are guides available for estimating the amount of defect in logs.
一旦直径和长度已经测量过，此原木测量标准就应该用于决定原木板英尺材积。但此原木测量标准是建立在圆且直并无不允许缺陷的基础上，因缺陷导致的材积短少应单独计算，并从原木测量材积总数中扣减。可参考原木缺陷数量的估算。
