## How to Draft a Basic Pant Pattern

Written Instructions with accompanying video for anyone who wants to make a basic pant exactly to your measurements! Please get your correct measurements before you begin from How to Take Your Measurements.

Note: Solid lines are the final cutting lines. Dotted lines are only for reference.

## Part 1: Starting

- 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. Connect point**3**to**4**. - From point
**1**towards point**2**apply ¼ the hip circumference and mark it as point**5**. - 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. - 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**). Connect each set of points with a dotted line. These lines are for reference. - Mark the the points where the horizontal dotted lines intersect the vertical center line (starting from the top) as points "
**a**", "**b**" and "**c**".

## Part 2: Front Pattern

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

## Part 3: Back Pattern

- From
**1**towards**5**apply 2.5 cm and mark point**17**. - From
**17**move upwards 2.5 cm and mark point**18**. - From
**18**to the top line (**1-2**) apply ¼ the waist measurement + 2 cm and mark that point**19**. - Connect point
**19**to point**a**with a dotted line. - Measure to the center of segment
**19-a**, and square a 0.5 cm line outward (towards the right) . - Draw the hip curve connecting
**19**to**a**passing through the end of the new line. - From point
**7**towards point**1**apply 2.5 cm ad mark point**20**. - From point
**9**towards the left draw a line applying the back crotch measurement, which is calculated as: 45% of ¼ hip circumference or front crotch multiplied by 3. The end of that line is point**23**. - Mark the center point between points
**18**and**19**and and mark it point**21**. - 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. - Draw a line about 4.5 cms long from point
**9**at a 45º angle. - 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. - From point
**11**to outside the rectangle mark 2 cm (point**f**). Apply the same distance from point**3**outwards (point**g**). - Connect the points
**23**and**f**. In the middle of this segment raise a short 0.5 cm line. - Draw the inseam
**23**to**f**again with a slight curve which passes through the new point. - From
**c**towards 11 apply 1 cm (point**h**). - Mark the same distance from point
**6**towards point**3**(point**i**). - Draw the side connecting points
**a-b-h-i**. - Connect points
**f**and**g**and finish the back pattern by connecting the hemline points**g**and**i**. - 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.

Love this. Thank you!

Finally!!!! thanks guys.

very usefull ! Thank you !

Thank you so much for this series! I'm watching your video, but was thrilled to find these notes. I hate to bring this up, but I can't read most of the numbers on the graphic. Is there any way to make them darker? Or are these common graphics and I could find the graphic somewhere else?: Thanks so much.

some additions:

step 2.7: mark the new point 16

step 2.12: point c is not yet defined here. I gather it must be where 5-6 and 11-12 intersect.

step 2.13: point b is not yet defined here. I gather it must be where 5-6 and 9-10 intersect.

step 3.5: is this line running in or out?

step 3.8: mark the new point 23

I made a straight forward software program based uopn this description. See How to Draft a Basic Pant Pattern Automated

i am having problems seeing the numbering on the pattern can anyone help

I like this

I lyk, it's useful

well done

oh my God ,Thanks a lot for the tutorial ...

I read the how to take your measurements page, but I'm still confused about the hip drop. Also the automated program did not draft all the lines.

How do I calculate the hip drop?

Thanks!

Adeline, I believe the hip drop is measured by sitting in a hard flat chair and placing a ruler next to the body. it is the measurement from the base of the chair to your waist. There is another video on this site that states that. Good Luck - my pattern came out a tad wonky and I will have to make alterations for sure.
