Pattern making is one of the important and essential sections in the apparel manufacturing industry. Before producing a garment to make pattern is must. Pattern is a hard paper which is made by following and individual component.

How to Make Production Pattern of Pant:
The measurement taken for making pattern are:
  1. Seat - 102 cm
  2. Waist – 82 cm
  3. Inside leg measurement – 76 cm
  4. Body rise – 28 cm
  5. Bottom width – 25 cm
  6. Waist band depth – 4 cm
Top side pattern (Front part):
From 0 point left side, right side and under side at 90 o angle three straight line are drawn.

0-1, Body rise + 1 cm – waist band depth
= 28 + 1 – 4
= 25 cm

Then from the point 0-1 the line is extended both sides perpendicularly. (1-2, Inside Leg measurement = 76 cm. Line is expanded both side perpendicularly).

2-3, Inside leg measurement ½ / (2+5) cm = 42 cm {1/2 measurement of (1-2) + 5 cm.}

1-4, ¼ (Body rise measurement). From point 4 a line is expanded both side perpendicular to (0-1) line.

1-5, 1/12 seat + 1.5 cm. From point 5 a perpendicular line is drawn on the line of (1-5), Indicate the point “6” and “7”.

6-8, ¼ (Seat measurement) +2 cm.

5-9, 1/16 (Seat measurement) + 0.5 cm

7-10, 1 cm. A curve drawn according to the figure from the point “9”, “6” and “10”.

10-11, ¼ of waist measurement + 2.5 cm.

2-12, ½ of bottom width

2-13, -Do-

Then 12-14 and 13-15 straight line are joined. 11-8 are draw curve 0.5 cm outside and 8-14 are drawn curve 0.5 cm inside which are compressed and expanded.

Now, Side seam is drawn from the point 11, 8, 14, 12.

Then 9-15, are drawn curve 1 cm inside which is compressed.

Inside legs are indicating the point 9, 15 and 13.

Under side pattern (Back part):
5-16, ¼ of (1-5). Then from point 16 a perpendicular line 1-16 drawn which indicate 17 and 18 point.

19, Mid point of 16 to 18.

18-20, 2 cm.

20-21, 1 cm.

9-22, ½ of (5-9) + 0.5 cm.

22-23, 0.5 cm. A curve is drawn from the point 23, 19 and 21 according figure.

21-24, (Waist) ¼ + 4.5 cm. (1/4 of waist + 4.5 cm)

25, Mid point of 21 and 24. From point 25 left side 1.5 and bottom side 12 cm.

17-26, (Seat) ¼ + 3 cm (1/4 of seat measurement + 3 cm)

12-27, 2 cm.

13-28, 2cm,

14-29, 2 cm.

15-30, 2 cm.

Then side seam is drawn from the point 24, 26, 29 and 27 and inside leg by adding points, 23, 30, 28.
