Frequently Asked Questions
How do I calculate curtain fabric needed for my window?
Use the formula: Fabric = (Window Width × Fullness Ratio × 2 panels) + seam allowance. For a 5-foot wide window with 2.5x fullness, you need (5 × 2.5 × 2) = 25 linear feet or approximately 3.75 meters of 44-inch width fabric.
What is the fullness ratio and why does it matter?
The fullness ratio determines how much fabric you gather for proper drape and coverage. Common ratios: Flat panels (1.5x), Pleated (2x), Gathered rod-pocket (2.5x), Sheer (3x). Higher ratios create more dramatic folds and fuller appearance. Lighter fabrics often use higher ratios for optimal flow.
How much extra should I add for hem and rod pocket?
Add 30-50cm to the height: typically 5-10cm for top rod pocket, 15-25cm for bottom hem, plus 5cm for seam allowances. For most windows, adding 30cm total ensures proper fit and finishing. Always add extra for hems and seams to your measured height.
What's the difference between 44-inch and 54-inch fabric width?
44-inch (1.12m) width is standard Indian fabric, requiring more pattern pieces for wider windows. 54-inch (1.37m) width is European standard, allowing wider curtain panels with fewer seams. 120-inch (3m) is luxury blackout width, covering large windows with one cut. Choose based on window size and desired panel configuration.
How much fabric do I need for a 6-foot sliding door?
For a 6-foot (1.8m) door with 2.5x fullness: (1.8 × 2.5 × 2) = 9 meters of standard 44-inch fabric. Add 40cm extra for hem and rod pocket, totaling approximately 9.4 meters. Door curtains often require more fullness than windows for practical use.
Should I buy more fabric than calculated?
Yes, always buy 10-15% extra fabric for shrinkage, pattern matching, and mistakes. For 10 meters, purchase 11-11.5 meters. Pre-wash natural fabrics like cotton and linen before cutting. Some patterns require extra fabric for alignment—consult with your fabric seller for pattern repeats.
What fabric width should I choose for my curtains?
For windows under 2 meters wide, 44-inch (1.12m) standard fabric is economical with one seam. For 2-4 meter wide windows, 54-inch (1.37m) reduces seams. For wider windows or minimal seams, choose 120-inch (3m) width. Consider the pattern repeat and your sewing skill level.
How do I calculate fabric for corner windows or bay windows?
Measure each section separately and add the totals. For a bay window with three sections (2.5m total), calculate as: (2.5 ÷ 3) × 2.5 fullness × 2 panels = approximately 8-9 meters. Always measure from the outermost point to the wall corner for accurate coverage.
