Lining Cut Calculator

Lining fabric behaves differently than shell fabric and doesn't need to move with the body the same way, so it's cut with garment-specific adjustments rather than a 1:1 copy of the shell dimensions. Jackets and coats add length and width for a jump hem and ease of movement, while skirts and dresses are cut shorter than the shell so the lining sits just inside the hemline instead of hanging below the outer fabric.

An ease pleat is a small fold sewn into the center back of a lining that releases extra fabric when the wearer moves their arms or shoulders, preventing the lining from tearing or restricting motion. Jackets and coats include one because they're worn over the shoulders and arms move freely inside them; skirts and dresses don't need it since they don't cover the shoulder area in the same way.

Match it to the garment you're actually lining, not the fabric weight or style detail — the calculator only distinguishes Jacket, Skirt, Dress, and Coat because each has a different standard length adjustment and hem reduction. If your garment doesn't fit neatly into one category (a lined vest, for example), choose whichever option is closest in construction and adjust the seam allowance or add extra ease by hand afterward.

It's the cut length (lining length plus both seam allowances) with the one-inch lining hem allowance added on top, giving you the single figure to use when calculating yardage for a single lining panel. It does not include the lining width or account for multiple panels — for a full garment you'll typically need this length for each front and back piece your pattern calls for.
