How to Read a Sewing Pattern Yardage Table

Every commercial sewing pattern includes a yardage table on the envelope. Here is how to read it correctly:

  1. Find your size — Pattern envelopes list yardage by size (XS–XL or numbered). Circle your size column.
  2. Check the view — Patterns include multiple "views" (A = dress, B = top, C = jacket). Each view has its own row.
  3. Match fabric width — Yardage tables show amounts for 45" and 60" fabric. Choose the column matching your fabric.
  4. Read the number — Yardage is given in decimal (1.25) or fractional (1¼) format. 0.5 = ½ yard, 1.75 = 1¾ yards.
Common mistake: Pattern yardage tables assume standard fabric widths. If you're using 36" quilting cotton for a garment that recommends 45", you may need 25–50% more fabric. Always verify with the calculator above.

Adjusting Pattern Yardage for Your Size

Pattern envelopes list yardage for the straight size range. If you are between sizes or have graded between sizes, here is how to adjust:

  • One size up — Add ¼ yard for most garments. The pattern piece width increases slightly.
  • Two sizes up — Add ½–1 yard depending on garment fullness (more for flared styles).
  • Tall/long adjustments — If you need to lengthen the pattern by 2"+ (longer torso, longer inseam), add ¼–½ yard.
  • Napped fabrics — Velvet, corduroy, and fleece require all pieces cut in the same direction. Add ¼–½ yard.

The easiest way to verify: lay out your pattern pieces at the correct width and measure the longest piece plus seam allowance. Enter that into the calculator above.

Pattern Yardage by Garment Type

Approximate yardage ranges for standard patterns (45" fabric, size M). Always check your specific pattern envelope:

Pattern Layouts and Fabric Width

Your pattern envelope shows two layout diagrams: one for 45" fabric and one for 60". The layout determines how many yards you actually need:

  • Narrow fabric (36–45") — Pieces are laid end-to-end, requiring more length. Common for quilting cottons and apparel fabrics.
  • Medium fabric (54") — Most home decor pieces fit side-by-side. Saves about 20% yardage vs 45".
  • Wide fabric (60") — Garment pieces often fit across the full width. Saves 25–33% yardage vs 45".

When calculating fabric yardage, always start with the width you plan to buy. The fabric width converter helps compare options.

Frequently Asked Questions

What if my fabric width doesn't match the pattern table?
Use the calculator above. Enter your fabric width and the dimensions of your largest pattern pieces. Compare the result to the pattern table — if it differs by more than ¼ yard, buy the larger amount.
Does the pattern include extra for shrinkage?
No. Pattern yardage assumes pre-washed fabric at its stable size. Pre-wash your fabric and add 5–10% (set waste % in the calculator) for natural fiber shrinkage.
How do I calculate yardage for a multi-size pattern?
Trace the largest size you need. Measure the widest and longest pattern pieces (including seam allowance). Enter those into the calculator. Add ¼ yard if cutting multiple sizes from one layout.
