Step 1 Starting

  1. Draw a rectangle as follows: From point 1 to point 2 half the hip measurement. From point 1 to 3 and 2 to 4 the desired pant length.
  2. From point 1 towards point 2 apply ¼ the hip circumference and mark it as point 5.
  3. From point 3 towards point 4 do the same as in the previous step and mark point 6. Connect points 5 and 6 with a straight line.
  4. From point 1 towards 3 and 2 towards 4 apply the hip drop (points 7 and 8), front crotch (points 9 and 10), and knee level (points 11 and 12).

Step 2 Front pattern

How To Draft a Basic Pant Pattern

  1. From 2 towards 8 go down 2.5 cm and mark point 13.
  2. From 13 towards the center of the rectangle measure in 2.5 cm and mark point 14.
  3. From 14 towards the line connecting 1 and 2 apply ¼ waist measurement and mark point 15.
  4. Connect point 15 with point "a". (Point "a" being the intersection of the hip drop with the center line 5-6.)
  5. Find the center point of the segment 15-a and measure out 0.5 cm on the perpendicular.
  6. Draw the hip curve connecting points 15 and a passing through the new point.
  7. From point 10 towards the right apply the front crotch measurement. The front crotch measurement is calculated as follows: 15% of ¼ the hip measurement.
  8. From point 10 draw a 45º line measuring 1.5 cm.
  9. To draw the front crotch connect points 14 and 8 with a straight line and from point 8 to 16 with a curve passing through the very end of the 45º line.
  10. Connect points 16 and 12. Find the center between these and raise a squared line 0.5 cm (as in step 5).
  11. Draw the inseam by connecting points 16 and 12 with a curve passing through the end of the line.
  12. From c towards 12 mark point d 3 cm in and apply the same distance from point 6 towards 4 to create point e.
  13. Draw the front side by connecting points a-b-d-e.
  14. Connect points 12 and 4 and finish the front pattern connecting the hemline points e with 4.

Step 3 Back pattern

  1. From 1 towards 5 apply 2.5 cm and mark point 17.
  2. From 17 move upwards 2.5 cm and mark point 18.
  3. From 18 to the top line (1-2) apply ¼ the waist measurement + 2 cm and mark that point 19.
  4. Connect point 19 to point a.
  5. Measure to the center of segment 19-a, and square a 0.5 cm line.
  6. Draw the hip curve connecting 19 to a passing through the end of the new line.
  7. From point 7 towards point 1 apply 2.5 cm ad mark point 20.
  8. From point 9 towards the left apply the back crotch measurement, which is calculated as: 45% of ¼ hip circumference or front crotch multiplied by 3.
  9. Mark the center point between points 18 and 19 and and mark it point 21.   
  10. Draw a perpendicular line about 5 cms long from point 21 and mark the end point 22. Mark off 1 cm to either side of point 21 and connect two more straight lines from point 22 to these forming a dart which is 2 cms in depth.
  11. Draw a line about 4.5 cms long from point 9 at a 45º angle.
  12. Draw the back crotch by connecting points 18 to 20 with a straight line and from point 20 to 23 with a curve passing through the end of the new line.
  13. From point 11 to outside the rectangle mark 2 cm (point f).  Apply the same distance from point 3 outwards (point g).
  14. Connect the points 23 and f.  In the middle of this segment raise a short 0.5 cm line.
  15. Draw the inseam 23 to f again with a slight curve which passes through the new point.
  16. From c towards 11 apply 1 cm (point h).
  17. Mark the same distance from point 6 towards point 3 (point i).
  18. Draw the side connecting points a-b-h-i.
  19. Connect points f and g and finish the back pattern by connecting the hemline points g and i.
  20. Confirm that the distance between points 16 and 12 and points 23 and f match. If the back inseam is longer simply move point 23 down accordingly and redraw the inseam.
