Point name

SizeKorea’s definition

This study’s definition

1

Back neck

Most prominent point of the spinous process of the seventh cervical vertebra

The posterior point of the lowest cross section among the cross sections with a deviation of less than 9% from the minimum neck circumference (Fig. 2)

2

Front neck

Crossing point between the neck line and the front center line

The innermost point in the sagittal plane erected from the anterior neck center point of the minimum neck circumference

3

Side neck

The point where the top of the trapezius muscle meets the anterior edge at the neck line

A point on the neck line at the mid-point of the depth between the front neck point and the back neck point

4

Shoulder

Most lateral point of the acromial process of the scapula

The average point of the coordinate values of the highest points of the extracted closed curves (3 in Fig. 5) in the shoulder area

5

Axilla

The lowest point of the fold line that is formed in the axilla region when the arm is kept close to the body

The lowest point of the extracted curve passing a temporary axilla point (2 in Fig. 5) and the shoulder point

6

Front axilla fold

The highest point of axilla folding on the front

The front point on the position where the deviation between the adjacent transverse lines formed from the bottom to the top of the armscye line cross section becomes smaller than 0.8 (Fig. 4)

7

Back axilla fold

The highest point of axilla folding on the back

The back of the position where the deviation between the adjacent transverse lines formed from the bottom to the top of the armscye line cross section becomes smaller than 0.8

8

Front mid-axilla

Mid-point of the distance between the shoulder point and front axilla fold

Same as SizeKorea's definition

9

Back mid-axilla

Midpoint of the distance between the shoulder point and the back axilla fold

Same as SizeKorea's definition

10

Back waist

The height of the side waist point marked on the back mid-sagittal line

The point recessed the most toward the inside of the body on the back plane from the axilla level to the crotch level

11

Front waist

The height of the side waist point marked on the front mid-sagittal line

The point at the height of the back waist point marked on the mid-sagittal line

12

Side waist

The most recessed point in the right lateral contour of the body, or 1/2 point of the distance between the point of the tenth rib and the point of the iliac crest

The point at the 1/2 position of the thickness between the front and back points of the waist

13

Bust point

Most anterior protrusion of the bra cup on women

Same as SizeKorea's definition

14

Scapular

There is no definition

The point at the level of the back mid-axilla point on the line connecting the bisecting point of the distance between the side neck point and the shoulder point and the bisecting point of the distance between the back waist and the side waist point

15

Back protrusion

The point of axillary level marked on the spine (axillary level point on the spine)

The most protruding point on the line connecting the bisecting point of the distance between the side neck point and the shoulder point and the bisecting point of the distance between the back waist and the side waist point
