Lesson 2: Create A Pattern By Tracing Existing Pants

Learn the correct method for tracing an existing pair of pants. If done incorrectly, your new pants will not fit right. With just a few tips and tricks, you can create new pants that fit as well as your existing pants.

Alter your "master pattern" to create crop pants, flare leg, low waist, ankle length, or shorts. Easily change the size of the pattern. Add borders, a drawstring, embroidery or other details to make them uniquely yours.

Use this same pattern to create nice-flowing comfy casual or dress pants (such as from rayon or rayon-polyester). Go to our free sewing book to learn how to add pockets. One pattern can be turned into a wardrobe of pants and pajama pant patterns!



Pant Pattern Basic Information

A pair of pants is generally made with a center seam down the front, a center seam down the back, a side seam on each outer side and an inside seam (inseam) on the inside of each leg. That is how our pants will be constructed, so our pattern will be created in this style. The back waistline comes up a bit higher than the front. This creates a good fit and is why I make my own pj's. Store-bought pj's often cut the back too low and this creates a problem when bending over ("plumber pants"). When you make your own pattern, you can cut the front lower (low slung look) and the back higher for a nice fit. If you want both front and back lower, that is fine too - it's your choice. Customize the fit to your own taste.

Trace Pant Front To Get Basic Shape

Start by creating a general shape for the front. Lay your pants over paper so that half of the front is lying flat on the paper, as shown in the photo. Note that the waist slopes DOWN slightly from the hip to the center front. The hemline of the pants should be straight across, horizontally.

Tip: I use large sheets of butcher paper. I also use a large sewing ruler, plus my large cutting mat. These tools make proper measuring much easier, plus they help me keep my lines straight.

Adjust Waistline

The waistline of the finished pants is small, because it has elastic sewn in. We need to adjust for this. The waist must be cut larger, and it will be brought in smaller when elastic is added to the waistband.

Make a mark on the paper at the center seam of the pants. Keeping the pants center in line with the line drawn on the paper, pull the waist of the finished pants out to the end of its stretch capability. Mark the paper at this point. The front center line must be straight up, vertically, so any addition to width is added to the OUTSIDE of the pant leg (the outer seam). I enhanced the photo with a red dot to show the new outer edge of the waist.

Adjust Inseam & Center Front

Use a ruler to trace over the center front line. It needs to be straight, vertically. Use the ruler to trace over the inseam. Fill in the center crotch line (curved edge).

Use the ruler to draw the outer seam line, hem and waistline.

Check Your Pattern

Lay the original pants over your new pattern to check fit. I have enhanced lines and marks in the photo. The blue lines mark the center front at the top, and the center crotch. Make sure your pattern matches your original pants at these points.

At this point, you can alter the pattern to customize the style. Add to pant leg length, create flare leg, capri, etc. Refer to Lesson 1: Pajama Pattern to learn how to make alterations to your pattern.

Add Seam Allowances, Hem & Waistband

trace pant front Add 1.25" to the top of the pattern (waist); this will be turned down 1.25" for the waistband. Note that the waist slopes from the center front to the hip. Add enough to the pant leg to allow for your desired hem plus 1/4". For example, if you want a 1" hem, add 1.25" to the pant leg length. The waistband will be turned down 1/4", and then another 1". Same with the pant leg hem.

Add 1/14" to all other sides to allow for a 1/4" seam allowance (center front, side seam and inseam).

TIP: I cut an angle off the top outer corner (hip) because the upper area will be folded down 1.25". If it is not cut, there will be excess fabric when the waistband is created. Try it - cut the angle off, then fold the upper edge down. It should line up if the angle is cut correctly. It should be the same angle as the main piece, but a mirror image. Do this with hemlines of skirts, pants, or any other item that has an angle at the edge.

At this point, you can alter the pattern to customize the style. Add to pant leg length, create flare leg, capri, etc.
Refer to Lesson 1: Pajama Pattern to learn how to make alterations to your pattern.
Refer to Lesson 4: Attach A Cuff to learn how to adjust the pant leg length to allow for a cuff.

Repeat For Back

Adjustments To Create Back Piece

The crotch outer point is drawn further out than the front piece. I used a ruler to draw a new point about 3/4" further out. The photo on the right shows a red dot on the back where the original crotch outer point was. Keeping the inseam the same length, I simply drew the point out further. This was for a toddler size 2 - an adult size would be a larger addition. Lay your pants leg back over your pattern to see how far you should extend this point. Be sure the inseam length on the back pattern piece is equal in length to the inseam on the front pattern piece. The width at the hemline should be equal between front and back as well.

The waistband is cut straight across (horizontally) on the back, rather than sloping down toward the center. From the outer seam line, draw the waistline straight across to the center seam, extending the center seam upward as necessary. The photo above shows a blue dot where the original waist center point was. The outer seam length is not changed.

When finished, lay the back finished pant leg over your pattern to be sure the pattern is correct. Double check key measurements. The following measurements must match (be of equal length) between front and back pieces: pant leg hem width, outer seam, inseam.
