Measure Your Laptop for a Lined Laptop Case
Sewing your own laptop case will save you money and protect your notebook computer. Make a basic case following these directions, and feel free to be creative by adding pockets or straps to customize your laptop case even more.
You will need:
- The laptop
- A tape measure
- A pencil or pen
- Pattern material -- newsprint paper, the back side of gift wrapping paper, interfacing or similar material.
- Fabric (amount will depend on your laptop pattern) and optional double fold bias tape to enclose the upper edge... of the case depending on the fabric you are using. You will need equal amounts of the outer fabric and the lining.
- 1" or wider hook and loop tape (Velcro) to close the case. The amount you need will depend on how you design the flap and the security you want.
Measure the Laptop
Continue to 2 of 10 below.
- A: The distance around the laptop from top edge to the other top edge. Add 1/2" for a seam allowance at the top of the case. Shown in Green
- B: The amount of flap you want, starting at the second top edge to the amount you want to overlap the front of the case. Add a 1/2" for a seam allowance at the edge of the flap. Shown in yellow.
- C: The thickness of the laptop. Shown in red.
- D: The width of the laptop. Shown in blue.

Make the Pattern and Choose Your Fabric
- Add the thickness of the laptop measurement (C) to the width of the laptop measurement (D). This will be the width of your pattern and is shown as D in the photo.
- Add the distance around the laptop (A) to the amount of flap you want (B). This will be the length of your pattern pieces.
- Using a carpenters square, rotary cutter rulers or pattern making the material with a grid to maintain perfect square, transfer the measurements to your pattern material.
- Create the line for where the flap starts... using measurement b from the end of the pattern piece.
- Add a 1/2" to the long side edges as a seam allowance.
- Mark where the flap begins.
- Design the front flap into the shape desired. Keep both sides of the flap even by folding the pattern in half lengthwise and trim the flap as desired. You can create angles or round off the edge as you desire but remember to leave a large enough area for the hook and loop tape to create a secure closing.
Choose Your Fabric
Choose a fabric that will not scratch the laptop and one that will hopefully help protect the laptop from bumps and moisture.
Continue to 3 of 10 below.
- Following these directions, it will be possible to use a weather-resistant nylon fabric or a vinyl fabric for the outside of the case and a fleece or flannel lining to provide a soft interior in the case.
- Always preshrink your fabric.

Cut and Mark
Continue to 4 of 10 below.
- Use the straight grain of the fabric to run parallel with the edges of the pattern piece.
- Using preshrunk fabric, cut out one of the patterns from the outer fabric and cut out one of the lining fabric.
- In the seam allowance area, transfer the mark where the flap begins.

Continue to 5 of 10 below.
- Fold the straight end of the fabric up to the flap mark with the right sides of the fabric together.
- Align the edges and sew a seam using a 1/2" seam allowance.
- Apply a seam finish to the seam allowance.
- Press the seams.

Square the Corners
Continue to 6 of 10 below.
- Re-fold the case so the seam is laying on the bottom of the bag as shown in the photo.
- Using the measurement you have for the thickness of the laptop, measure across the seam and mark where the thickness is achieved.
- Sew across the seam at the mark as shown in the photo.
- Trim off the triangle and apply a seam finish.

Sew Hook Tape
Continue to 7 of 10 below.
- Working on the right side of the lining case, center the hook portion of the hook and loop tape on the flap, 3/4" away from the cut edge.
- Sew the tape to the case by sewing along the edges of the tape, pivoting with the needle down at each corner.

Turning One Case
Continue to 8 of 10 below.
- Turn the outer case right-side out and insert it inside the lining case so the right sides of both cases are against each other.

Sew the Cases Together
Continue to 9 of 10 below.
- Match the seams and align edges.
- Pin in place, using double pins to remind you to leave an area of the inside top edge open.
- Sew the edges together, using a 1/2" seam allowance, leaving an area open on the inside top edge to turn the case.

Clip and Turn
Continue to 10 of 10 below.
- Clip the case at the seams and any turns created on your flap design.
- Grade the seam allowance if desired to eliminate bulk.
- Turn the case right side out through the opening.
- Press the edges smooth and flat with the seam pushed to the edges.
- Slip stitch the opening closed.

Top Stitch and Loop Tape
- If possible the layers near the edge to keep the layers from shifting. (If you are using a vinyl that will show pin holes, use stationary clips, paperclips or clothespins to hold the layers and remove the "pins" as you sew up to them.}
- Top stitch the edge using a guide, such as your sewing machine foot and needle position, to keep the stitching an even distance from the edge.
- Close the case and find the position for the loop tape.
- Pin the tape in place.
- Sew the tape in place, pivoting with... the needle down, sewing through both fabric layers.
- Enjoy your new case!
