💡 What does "3 Panels / Strips per side" mean?
Curtain cloth from factories comes in rolls of standard width (54 inches / 137 cm). Because your window is wider than that, the master tailor neatly stitches 3 strips of cloth side-by-side for each curtain. The seams are hidden inside the pleat folds so they are invisible from the front!

Methodology & Specification
The Mathematical Formula: How to Calculate Curtain Fabric
Curtain fabric is sold by linear meter off the roll. Because rolls have a fixed width (typically 54 inches / 137 cm), windows wider than 1 meter require vertical joining cuts. Here is the verified mathematical model executed by our calculator:
Step 1: Gathered Width Across the Track
Multiply your track width by the fullness ratio, then add 20 cm for side hem turns (10 cm per side):
Gathered Width (cm) = (Track Width × Fullness Ratio) + 20 cm
Step 2: Number of Vertical Fabric Cuts (Widths)
Divide gathered width by the usable roll width (roll width minus 4 cm selvedge allowance). Round up to whole cut. For pairs, round up to an even number:
Number of Cuts = ⌈ Gathered Width ÷ (Roll Width - 4 cm) ⌉
Step 3: Cut Length Per Width (With Hem Allowances)
Add 15 cm for the top heading tape fold and 20 cm for a double bottom hem (total 35 cm hem allowance). If pattern repeat > 0, round up to the nearest repeat multiple:
Cut Length (cm) = Finished Drop + 15 cm (Header) + 20 cm (Double Bottom Hem)
Step 4: Total Fabric Meters
Multiply the cut length by total cuts, then divide by 100:
Total Fabric (Meters) = (Cut Length × Number of Cuts) ÷ 100

Curtain Fabric FAQs
Frequently Asked Questions
How much fabric do I need for curtains?
To calculate how much fabric you need: Multiply your curtain track width by your desired fullness ratio (usually 2.0x to 2.5x). Add 20cm for side hems. Divide by your fabric roll width (typically 54" / 137cm) to get the number of fabric cuts. Multiply the number of cuts by your cut length (finished drop + 35cm for top header and double bottom hem). Finally, divide by 100 to get total meters required.
What is the best curtain fullness ratio for living rooms and bedrooms?
For a rich, luxurious look in living rooms and bedrooms, a 2.5x fullness ratio (Triple Pinch Pleat) or 2.2x fullness (Wave / S-Fold drapery) is recommended. For casual curtains, dining spaces, or sheer curtains, a 2.0x fullness (Eyelet or Pencil Pleat) provides clean, beautiful gathers without excessive bulk.
What is the difference between standard 54-inch fabric and 108-inch seamless fabric?
Standard 54" (137cm) fabric rolls are stitched vertically in cuts (panels) to span wide windows, creating vertical seams down the curtain. Extra-wide 108" or 120" (274cm - 300cm) seamless fabrics run horizontally along your track. Because the roll width covers your room height, you get one continuous curtain with zero vertical join seams.
How does pattern repeat affect fabric yardage?
If your curtain fabric has a printed or woven pattern (e.g., damask, floral, or geometric), adjacent fabric cuts must align horizontally at the seams. Each cut length must be rounded up to the nearest multiple of the vertical pattern repeat. This typically adds 10% to 20% more fabric depending on repeat height.
How much extra fabric is needed for curtain hems and headers?
Professional master tailors recommend adding 35cm (approx. 14 inches) to your finished curtain drop: 15cm for the top heading tape fold and buckram, and 20cm for a weighted double 10cm bottom hem. Double bottom hems give curtains their straight, weighted drape.
