自柱骨下行腋中不见者，长四寸（柱骨，颈项根骨也）
腋以下至季胁，长一尺二寸（季胁，小肋也）
季胁以下至髀枢，长六寸（大腿曰股，股上曰髀，楗骨之下，大腿之上，两骨合缝之所
曰髀枢，当足少阳环跳穴处也）
髀枢下至膝中，长一尺九寸。
横骨上廉下至内辅之上廉，长一尺八寸（骨际曰∶廉膝旁之骨突出者曰辅骨，内曰内辅
，外曰外辅）
内辅之上廉以下至下廉，长三寸半（上廉下廉，可摸而得）
内辅下廉下至内踝，长一尺二寸。
内踝以下至地，长三寸。
肩至肘长一尺七寸。
肘至腕长一尺二寸半（臂之中节曰肘）。
腕至中指本节长四寸（臂掌之交曰腕）。
本节至末长四寸半（指之后节曰本节）。
膝以下至外踝长一尺六寸。
膝 以下至跗属长一尺二寸（ ，腿弯也。跗，足面也。膝在前， 在后，跗属者凡两
踝前后，胫掌所交之处，皆为跗之属也。）
跗属以下至地长三寸。
外踝以下至地长一寸。
足长一尺二寸，广四寸半。
按∶骨度乃《灵枢经》骨度篇之文，论骨之长短，皆古数也。然骨之大者则太过，小者
则不及，此亦言其则耳。若周身手足折量之法，用前中指同身寸法为是。同身寸量法，详刺灸

From the Zhu Gu (the bone at the root of the neck) downward to the center of the axilla, the length is 4 cun.
From below the axilla to the Ji Xie (the lower costal margin), the length is 1 chi 2 cun.
From below the Ji Xie to the Bi Shu (the junction between the upper thigh and the lower part of the Jian bone, corresponding to the Huan Tiao acupoint of the Foot-Shaoyang Gallbladder Meridian), the length is 6 cun.
From below the Bi Shu to the center of the knee, the length is 1 chi 9 cun.
From the upper border of the Heng Gu (pubic bone) to the upper border of the Nei Fu (inner condyle of the tibia), the length is 1 chi 8 cun (the edge of a bone is called "Lian"; the protruding bones beside the knee are called "Fu Gu", with the inner one being Nei Fu and the outer one being Wai Fu).
From below the upper border of the Nei Fu to its lower border, the length is 3.5 cun (both the upper and lower borders can be palpated).
From below the lower border of the Nei Fu to the medial malleolus, the length is 1 chi 2 cun.
From below the medial malleolus to the ground, the length is 3 cun.
From the shoulder to the elbow, the length is 1 chi 7 cun.
From the elbow to the wrist, the length is 1 chi 2.5 cun (the middle segment of the arm is called the elbow).
From the wrist to the base of the middle finger (the proximal interphalangeal joint area), the length is 4 cun (the junction between the arm and palm is called the wrist).
From the base of the middle finger to its tip, the length is 4.5 cun.
From below the knee to the lateral malleolus, the length is 1 chi 6 cun.
From below the knee to the Fu Shu (the popliteal fossa posteriorly; Fu refers to the dorsum of the foot; since the knee is anterior and the popliteal fossa is posterior, Fu Shu refers to the areas around the anterior and posterior aspects of both malleoli where the tibia meets the sole), the length is 1 chi 2 cun.
From below the Fu Shu to the ground, the length is 3 cun.
From below the lateral malleolus to the ground, the length is 1 cun.
The length of the foot is 1 chi 2 cun, and its width is 4.5 cun.
Note: The Bone Proportions method originates from the "Bone Proportions" chapter of the *Ling Shu Jing* (Spiritual Pivot), discussing the lengths of bones according to ancient standards. However, individuals with larger bones exceed these measurements, while those with smaller bones fall short; this text merely states the general standard. For measuring the limbs and body using proportional folding methods, the Front-Middle Finger Cun method is appropriate. The measurement technique for Cun based on individual proportions is detailed in the *Ci Jiu Zhao Jian Gu Ge Tu* (Illustrations for Acupuncture and Moxibustion Examination of Bone Structure) (lost) and the *Xi Yuan Lu Shi Ge Tu* (Illustrations of Corpse Forms in the Xi Yuan Lu) (lost).
