头部
项发以下至背，骨长二寸半。（自后发际以至大椎项骨三节处也）
【按】头部折法∶以前发际至后发际，折为一尺二寸。如发际不明，则取眉心，直上后至大杼骨，折作一尺
八寸，此为直寸。横寸法∶以眼内角至外角，此为一寸，头部横直寸法并根据此。

上陷中而言，即天突穴处）缺盆以下 之中，长九寸。
胸围四尺五寸。
两乳之间，广九寸半。（当折八寸为当）
中下至天枢，长八寸。（天枢足阳明穴名，在脐旁，此指平脐而言）
天枢以下至横骨，长六寸半，横骨横长六寸半。（毛际下骨曰横骨）
【按】此古数，以今用上下穴法参较，多有未合，宜从后胸腹折法为当。

头部
从项部发际线以下至背部，骨骼长度为二寸半。（这是指从后发际线直到大椎穴所在的第三颈椎棘突处。）
【按语】头部的折量方法：从前发际线到后发际线，折算为一尺二寸。如果发际线不清晰，则取眉心，垂直向上量至大杼骨，折算为一尺八寸，这称为直寸（纵向尺寸）。横寸（横向尺寸）法：以眼内角至外角的距离作为一寸，头部横向和纵向尺寸的基准均依据此标准。
胸腹部
结喉以下至缺盆中，长度为四寸。（这是指从锁骨上窝中央的凹陷处而言，即天突穴所在的位置。）从缺盆以下至胸部中间，长度为九寸。
胸围为四尺五寸。
两乳之间的距离，宽度为九寸半。（此处应当折算为八寸才恰当。）
从中脘以下至天枢，长度为八寸。（天枢是足阳明胃经的穴位名称，位于脐旁，这里指平齐肚脐的位置。）
从天枢以下至横骨，长度为六寸半；横骨的横向长度为六寸半。（阴毛下方的骨头称为横骨。）
【按语】这些是古代的数值，用现在上下穴位的方法进行比较，大多不相吻合，适宜采用后面的胸腹折量方法才恰当。
两髀（大腿）之间的距离，宽度为六寸半。（这是指两股之间，横骨两端的位置，俗称髀缝。）
【按语】胸腹部的折量方法：直寸以身体中线为准，自缺盆处的天突穴起，至岐骨际上方的中庭穴止，折算为八寸四分；自上岐骨际下方至脐心，折算为八寸；脐心下方至毛际处的曲骨穴，折算为五寸。横寸以两乳头之间的距离折算为八寸。胸腹部的横向和纵向尺寸法均依据此标准。
背部
脊骨（膂骨）以下至尾骶骨共二十一节，总长度为三尺。（膂骨即脊骨，脊骨外部细小而内部粗大，人之所以能负重，是因为这块骨头巨大。脊骨共有二十四节，这里说二十一节，是因为排除了颈部的三节不在计算范围内。）
腰围为四尺二寸。
【按语】背部的折量方法：自大椎穴至尾骶骨，总共折算为三尺。上部七节每节长一寸四分一厘，共九寸八分七厘；中部七节每节长一寸六分一厘，共一尺一寸二分七厘；第十四节与脐平齐，下部七节每节长一寸二分六厘，共八寸八分二厘，总计二尺九寸九分六厘，不足四厘的部分是有零头未完全计入。直寸依据此标准，横寸使用中指同身寸法。
脊骨内部的宽度为一寸。凡是提到第二行挟脊一寸半、三行挟脊三寸的情况，都要除去脊骨的一寸宽，净以一寸半或三寸来计算，所以在第二行应当是二寸，在三行应当是三寸半。
侧部
自柱骨下行至腋中看不见的部分，长度为四寸。（柱骨，即颈项根部的骨头。）
腋下至季胁，长度为一尺二寸。（季胁，即小肋。）
季胁以下至髀枢，长度为六寸。（大腿称为股，股的上部称为髀楗，骨之下、大腿之上，两骨结合缝隙的地方，称为髀枢，对应足少阳胆经的环跳穴处。）
髀枢下至膝中，长度为一尺九寸。
横骨上缘下至内辅骨上缘，长度为一尺八寸。（骨际称为廉，膝盖旁边的骨头，突出者称为辅骨，内侧称为内辅，外侧称为外辅。）
内辅骨上缘以下至下缘，长度为三寸半。（上缘和下缘可以通过触摸得到。）
内辅骨下缘至...（原文此处可能有脱漏或重复，依文意应为至某处），长度为三寸半。（上缘和下缘可以通过触摸得到。）
内辅骨下缘至内踝，长度为一尺二寸。
内踝以下至地面，长度为三寸。
四肢部
肩部至肘部，长度为一尺七寸。
肘部至腕部，长度为一尺二寸半。（手臂的中段称为肘。）
腕部至中指本节，长度为四寸。（手臂与手掌交接处称为腕。）
本节至指尖末端，长度为四寸半。（手指的后一节称为本节。）
膝以下至外踝，长度为一尺六寸。
膝以下至跗属，长度为一尺二寸。（腘窝，即腿弯。跗，即足面。膝在前，腘在后。跗属是指内外踝前后胫骨与足掌交接的地方，都属于跗的范围。）
跗属以下至地面，长度为三寸。
外踝以下至地面，长度为一寸。
足的长度为一尺二寸，宽度为四寸半。
【按语】骨度是《灵枢经·骨度篇》的文字，论述骨骼的长短，都是古代的数值。然而骨骼大的则超过这个标准，小的则达不到，这里只是说明一般的准则罢了。其周身手足的折量方法，使用前文提到的中指同身寸法是正确的。同身寸量法，详见刺灸书籍中。
Head
From the hairline at the nape of the neck downwards to the back, the bone length is two and a half cun. (This refers to the distance from the posterior hairline to the third cervical vertebra spinous process where the Dazhui GV14 acupoint is located.)
[Note] The measurement method for the head: From the anterior hairline to the posterior hairline, it is measured as one chi two cun. If the hairline is unclear, measure vertically from the glabella (Yintang EX-HN3) to the Dazhu BL11 bone, measuring as one chi eight cun; this is referred to as the longitudinal inch (Zhi Cun). For the transverse inch (Heng Cun): The distance from the inner canthus to the outer canthus of the eye is taken as one cun. The standards for both longitudinal and transverse measurements of the head are based on this.
Chest and Abdomen
From the laryngeal prominence (Jiehou) down to the center of the Quepen (supraclavicular fossa), the length is four cun. (This refers to the depression in the center of the supraclavicular fossa, which is the location of the Tiantu CV22 acupoint.) From below the Quepen to the middle of the chest, the length is nine cun.
The circumference of the chest is four chi five cun.
The width between the two breasts is nine and a half cun. (It is more appropriate to measure this as eight cun.)
From Zhongwan CV12 downwards to Tianshu ST25, the length is eight cun. (Tianshu is the name of an acupoint belonging to the Foot-Yangming Stomach Meridian, located beside the umbilicus; here it refers to the level of the umbilicus.)
From Tianshu ST25 downwards to the Henggu (pubic bone), the length is six and a half cun; the transverse length of the Henggu is six and a half cun. (The bone below the pubic hair is called Henggu.)
[Note] These are ancient measurements. When compared with the current method of using upper and lower acupoints, they often do not match. It is more appropriate to adopt the later chest and abdominal measurement methods.
The width between the two thighs (Bi) is six and a half cun. (This refers to the space between the two thighs, at the ends of the Henggu bone, commonly known as the groin crease.)
[Note] The measurement method for the chest and abdomen: Longitudinal inches are measured along the midline. Starting from the Tiantu CV22 acupoint in the Quepen, up to the Zhongting CV12 acupoint above the xiphisternal junction, it is measured as eight cun four fen. From below the xiphisternal junction to the center of the umbilicus, it is measured as eight cun. From the center of the umbilicus to the Qugu CV2 acupoint at the pubic symphysis, it is measured as five cun. Transverse inches are measured by the distance between the two nipples, calculated as eight cun. The transverse and longitudinal measurement methods for the chest and abdomen are all based on this.
Back
From the spinal column (Lv Gu) down to the coccyx, comprising twenty-one segments, the total length is three chi. (Lv Gu refers to the spine. The spine is small externally but large internally; humans can bear weight because of the magnitude of this bone. There are twenty-four segments in the spine; the mention of twenty-one excludes the three cervical segments.)
The waist circumference is four chi two cun.
[Note] The measurement method for the back: From Dazhui GV14 to the coccyx, the total length is measured as three chi. The upper seven segments each measure one cun four fen one li, totaling nine cun eight fen seven li; the middle seven segments each measure one cun six fen one li, totaling one chi one cun two fen seven li; the fourteenth segment is level with the umbilicus, and the lower seven segments each measure one cun two fen six li, totaling eight cun eight fen two li. The sum is two chi nine cun nine fen six li, with less than four fen remaining due to unaccounted fractions. Longitudinal inches are based on this standard, and transverse inches use the middle finger proportional inch method.
The internal width of the spinal column is one cun. Whenever it mentions "two rows flanking the spine at one and a half cun" or "three rows flanking the spine at three cun," one must subtract the one-cun width of the spine itself. Therefore, the net distance for the second row is two cun, and for the third row, it is three and a half cun.
Lateral Side
From the Zhu Gu (neck base bone) descending to the invisible part within the axilla, the length is four cun. (Zhu Gu refers to the bone at the root of the neck.)
From below the axilla to the Ji Xie (lesser ribs), the length is one chi two cun. (Ji Xie refers to the false ribs.)
From below the Ji Xie to the Bi Shu (hip pivot), the length is six cun. (The thigh is called Gu. The upper part of the thigh is called Bi Jian. The area below the bone and above the thigh, where the two bones join, is called Bi Shu, corresponding to the Huantiao GB30 acupoint of the Foot-Shaoyang Gallbladder Meridian.)
From below the Bi Shu to the center of the knee, the length is one chi nine cun.
From the upper margin of the Henggu to the upper margin of the Neifu (medial condyle), the length is one chi eight cun. (The edge of a bone is called Lian. The prominent bone beside the knee is called Fu Gu; the medial side is Neifu, and the lateral side is Waifu.)
From the upper margin of the Neifu downwards to its lower margin, the length is three and a half cun. (The upper and lower margins can be palpated.)
From the lower margin of the Neifu [to the next landmark], the length is three and a half cun. (The upper and lower margins can be palpated.)
From the lower margin of the Neifu to the medial malleolus, the length is one chi two cun.
From below the medial malleolus to the ground, the length is three cun.
Limbs
From the shoulder to the elbow, the length is one chi seven cun.
From the elbow to the wrist, the length is one chi two and a half cun. (The middle section of the arm is called the elbow.)
From the wrist to the proximal interphalangeal joint of the middle finger, the length is four cun. (The junction of the arm and palm is called the wrist.)
From the proximal interphalangeal joint to the tip of the finger, the length is four and a half cun. (The distal segment of the finger is called the proximal interphalangeal joint in this context.)
From below the knee to the lateral malleolus, the length is one chi six cun.
From below the knee to the foot dorsum connection (Fu Shu), the length is one chi two cun. (The popliteal fossa is the bend of the leg. Fu refers to the dorsum of the foot. The knee is anterior, and the popliteal fossa is posterior. Fu Shu refers to the areas where the tibia and foot sole intersect around the anterior and posterior aspects of both malleoli.)
From the Fu Shu downwards to the ground, the length is three cun.
From below the lateral malleolus to the ground, the length is one cun.
The length of the foot is one chi two cun, and its width is four and a half cun.
[Note] Bone measurements are derived from the "Bone Measurements" chapter of the *Ling Shu Jing*. They discuss the lengths of bones and represent ancient standards. However, individuals with larger bones may exceed these standards, while those with smaller bones may fall short; thus, these figures serve only as general guidelines. For measuring the limbs and extremities throughout the body, the middle finger proportional inch method mentioned earlier should be used. Detailed explanations of the proportional inch measurement method can be found in acupuncture and moxibustion texts.
