  • The pattern resizing process involves calculating new measurements and creating a muslin mockup.
  • Choosing the right fabric is crucial for maintaining the desired fit and style when resizing patterns.

Determine Needed Pattern Size

Determine Needed Pattern Size
You’ll want to first figure out your desired finished garment size and take measurements to calculate the pattern size needed for that fit.

Carefully measure your bust, waist, and hip circumferences as well as desired length to determine the pattern size that will best fit your body.

Trace the original pattern outline onto pattern paper, labeling pieces, grainlines, and notches.

Compare your measurements to the finished garment measurements on the pattern envelope to calculate how much you need to grade up each pattern piece.

Knowing your target size will let you proportionally enlarge the pattern while maintaining the original style lines.

For accuracy, consider creating a muslin mockup before cutting into final fabric.

Capturing and Editing the Pattern Photo

Capturing and Editing the Pattern Photo
You’ll want to take a clear, well-lit photo of the pattern template with your smartphone. Then, open the picture in a basic photo editing program like Paint to crop, resize, and print the enlarged sewing pattern.

Taking a Picture With Your Phone

Next, capture a sharp photo of the original-sized pattern using your smartphone camera.

  1. Frame the photo close-up, excluding background clutter.
  2. Adjust lighting and angle for maximum clarity.
  3. Fill the viewfinder with just the pattern piece.
  4. Keep hands out of the shot.
  5. Take multiple photos and select the best-framed image.

With a clearly composed, high-resolution photo, you’ll have the ideal foundation for cleanly enlarging and editing the sewing template digitally. Careful photo composition empowers crafters to professionally grade patterns at home.

Editing the Photo in Paint

After cropping the image, open the photo in a basic editing program to refine it before printing. Use Paint to precisely crop the edges and ensure that the pattern fills the page. In Image Properties, set the units to inches for accurate sizing. Resize the image by dragging the handles, enlarging the pattern to match your measurements.

Print multiple copies and tape the sheets together. Use graph paper to double-check the size and make small adjustments in the program if necessary.

Understanding Pattern Grading

Understanding Pattern Grading
As you prepare to resize your sewing pattern, gather your supplies for grading—like gridded pattern paper, tape, pins, and a grading ruler—then calculate and mark the new measurements right onto the template based on your figures.

When increasing length, divide that adjustment incrementally between the pattern sections rather than only adding at a single seam.

Supplies for Resizing Patterns

Before resizing a pattern, grab some basic supplies like paper, scissors, tape, and a ruler to make the grading process easier than pie.

  1. Graph paper for accurately enlarging the pattern pieces.
  2. Rulers and a tape measure for ensuring precise new dimensions.
  3. Scissors and a seam ripper for slicing the pattern apart.
  4. Tape for taping enlarged pieces back together.

Having the right tools on hand will empower you to expertly resize any pattern for a perfect custom fit.

Making the Pattern Match Your Measurements

Adjust the waistband by calculating extra length. Seam measurements matter; maintain consistency. Proportions matter—lengthen in harmony with other sections. Your newfound mastery empowers altering any pattern.

Liberation comes through transforming designs to fit, granting confidence in every stitch.
