A strict anatomical definition of leg length (LL) is the length of the femur + tibia. Due to the bipedal nature of the human species, “leg length” often is measured as: (femur + tibia + the height of the foot, from the tibia-talus articulation to the ground). Alternatively, the phrase “lower limb length” may be use to denote this linear dimension. In this paper, we use “leg length” to denote any of the measurements described below in section 3. We do so because in a living human being it is difficult to measure anatomical LL. The maximum length of the femur is measured from its head, at the proximal end, to its medial condyle, at the distal end. In life, the femur and pelvic bones overlap and the head of the femur is difficult to assess due to its articulation within the acetabulum. A high degree of body fatness may make these bony landmarks difficult, or, impossible, to access. Consequently, LL is often defined by an easier to measure dimension such as iliac height (IH) and subischial leg length (SLL). It is also possible to measure an estimate LL via the combination of thigh length (TL) and knee height (KH). Some studies employ only one of these measures as the indicator of LL.
Each of these measurements can be transformed in ratios, generally in relation to total stature and sitting height (SH) to give indications of body proportions. In this article we discuss the sitting height ratio (SHR), relative subischial leg length (RSLL), and the knee height ratio (KHR).

原帖一楼噼里啪啦引用了那么多专业的东东，无非是为了说明测量真正的下肢全长不容易，通常用髂嵴高或会阴高等表示腿长。
贫僧也在百度百科腿长中有说明——

下面那篇中文文献就是翻译原帖引用的那段话的。

Svetlana Iliac lenght is nearly 4* 4" ？according to the definition of "leg length" (femur + tibia + foot height), from the ground to the trochanter, Sevetlana fails to measure 4 *4 ". And why in the photos have measure in tall heels ？
俄罗斯大妈髂嵴高真的有132cm？根据腿长的定义——大腿长+小腿长+足高，即大转子点至地面垂距（尻娘注：其实真正的下肢长也不是大转子点高，还略高一点点），大妈根本没有132cm。还有吉尼斯也太不专业了吧，踩高跷量髂嵴高？

贫僧再注：这样拿卷尺量出来的未必是垂距，吉尼斯测量人体立姿高度绝对外行。要是贫僧量腿长，一定比吉尼斯好。

Svetlana assuming is close to 198cm tall with their tennis shoes, his legs are far from being 4 *4 "(132cm). I agree that Svetlana has long legs for her height, but in no way measure that. Their length iliac does not reach 130cm. If his legs were of 132cm and maintain proportional body of Svetlana, she would have to be more than 7 *7 "tall.
I do not really agree with this record, I think it*s a lie. Probably the longest legs woman in the world is to be found in women who exceed the 6* 10 ".
Yao Defen legs (if alive) are short in proportion to your body, but are longer than those of Svetlana.

假设大妈穿网球鞋身高为198cm，那她的腿长远远没有达到132cm，我认可大妈有很好的腿身比，但其实并没办法去测量其真正的腿长。就连髂嵴高都没到130cm。如果大妈腿长有132cm，那么她的身高就不止231cm。
所以我不同意吉尼斯那很外行的记录，尽管吹吧。如果世界最长腿女人被挖出来的话，身高至少208cm。
姚德芬腿身比不及大妈，但腿长超过大妈。

And of course the longest legs in the world today should not be feminine, I think we should measure Kosen legs, Brahim, Jun Cai and Ahmed. Morteza seems to have legs shorter than the other giants. Try Reza will measure the total length of the longer leg of Morteza.

当然，今天世界上最长的腿不应该是女性（尻娘注：十个男人九个虚报身高，十个女人九个虚报腿长。所以，申请吉尼斯纪录最高的人，一定是男人，申请吉尼斯纪录腿最长的人，一定是女人，呵呵~），我认为应该测量苏丹·克森、卜拉欣·塔奇乌拉、张俊才（尻娘注：张俊才腿身比非常厉害）、Ijaz Ahmed等的腿。与其他巨人相比Morteza Mehrzad似乎腿身比不好。

Jessica Pardoe is a good candidate, has legs as long as Svetlana (who always wears high heels to be measured).

最长腿女人，Jessica Pardoe是个不错的候选人，腿长和的大妈（喜欢踩高跷量腿长的坏淫）差不多。

It seems that Svetlana is between 6 *6 "and 6* 7" and not 6 *5 ". Has long legs for your height but not even 4*.

似乎大妈身高在198-201cm之间，不是196cm。虽然是长腿，但122m是没有的。

It is possible that women with "female legs longer," this last years (until his death) was Margo Dydek with more than 4ft legs length.

在玛尔戈·戴迪克见马克思之前，她或许是最长腿女人，腿长超过122cm。
