Lining Calculator

Calculation

Fabric length = (Shell length × Coverage × Garment multiplier + Hem + Seam + Pleat) × Body layers + Sleeve length

Panel width = (½ bust × Ease + 4 × Seam) × Garment width multiplier. The ease factor is applied to the girth/width term only.

For sleeved garments (jacket, coat), a full or half lining also lines both sleeves, so a sleeve length (~60-62cm plus hem and seam) is added — this is what makes a full jacket/coat lining come out at roughly 1.5-1.75 yards rather than just the body length.

Coverage types

• Full: whole garment length, plus sleeves on jackets/coats
• Half: lined to the waist (~55% of length); sleeves still lined
• Partial: front panels only (full garment length, no back or sleeve lining)

Jackets and coats include a 2.5cm centre back ease pleat allowance (1 inch at the seam, 5cm on the fold). Trouser lengths are doubled for two legs. The ease factor widens the panel only — it is not applied to length.
