Sewing Patterns: Finding the Right Size for You

Trace the history of pattern sizing, including vanity sizing, from hand-made to ready-to-wear, and learn to pick the right pattern size by comparing your body measurements to the pattern.

Master precise sewing by taking accurate measurements for every garment, using proper undergarments, maintaining upright posture, and using mirrors or a helper to mark consistent measurement points.

Learn key body measurements for selecting sewing patterns, including high bust, full bust, full hip, natural waist, front bust, across back, and high hip, plus tape alignment tips.

Use high bust, full bust, full hip, and natural waist measurements to select size, blend top and bottom, shorten or lengthen as needed, and apply grading.

Understand wearing ease and design ease in sewing patterns. Learn how blocks and slopers shape sizing, and how woven or knit fabrics influence ease for fit.

Learn how knits and wovens differ in garment making, read your pattern to determine knit or woven design for size, and compare two-way, four-way, and stable knits with stretch recovery.

Calculate stretch percentage to size patterns with knits designed for negative ease, swap two-way for four-way stretch, test fabric, and adjust size using the given formula.

Practice selecting pattern sizes by matching full bust, high bust, and waist to the size chart when buying or downloading patterns, using blending to adjust the waist.

Select PDF pattern sizes by using layers to print two sizes up and two down, guided by bust, waist, and hip measurements, then print and assemble once to test fit.

Choose a size based on your measurements and the knit's stretch, then apply a full or small bust adjustment if the bust doesn't fit, or adjust the size for ease.

Measure bodice and dress blocks from neck to hem, armhole to waist, and side seams; apply wearing ease, and double width measurements to obtain bust, waist, hip, and hem circumferences.

Learn how to take waist, hip, hem, and center front/back measurements for skirts, and assess sleeve, armhole, crotch depth, and inseam in pants to select the right pattern size.

Choose the pattern waist size from the size chart, blend between sizes toward the hip, and measure the waistband pieces to find the finished waist.

Separate the pattern pieces from the 1282 skirt, copy them without cutting too close to the lines, and keep information attached as you handle pleats and gathering.

Flatten and straighten all pattern pieces with a dry iron on low heat to ensure accurate measurements. Avoid ironing over tape and prep for measuring and sizing.

Measure the pattern’s waistband pieces to determine the finished waist, subtract seam allowances, double front and back to 32 inches, and compare with a 31-inch body waist for ease.

Identify where the finished garment hip measurement appears on pattern pieces and understand how ease affects fit. Compare body and finished measurements to choose the appropriate waist and hip sizes.

Learn how to measure the hip on a pattern without a marked hip line, including calculating waist and waistband width, subtracting seam allowances, and accounting for pleats.

Copy patterns to prevent mistakes and accommodate size changes for family members you sew for, using paper, tape, and a light box with careful marking.

Copy large pattern pieces in sections on a lightbox, mark sizes 18 to 16 with match points along side seam, then blend and true the pattern for a smooth transition.

Separate the pattern pieces and tape them to wide paper. Use a light box or window to copy all markings, blend lines, and store patterns in envelopes.
