For pleated curtains, we will suggest the curtain width is 1x of the curtain rod/track, measuring the length from the eyelet ring where the curtain hooks are attached.
For pleated curtains, the panel width is the width that pleats are already set. 1.8X-2.2X fabric usage in default to create pleats and folds. And panel width is from the left pleat end to the right pleat end, instead of the left curtain side hem to the right curtain side hem.
For pleats are permanently sewn to make, we normally make them in 180-220% fullness. For example, if rod or track length is 100 inches, you may order 2 panels each 50 inches width for pinch pleated, tailor pleated header style. You could also order more width if you prefer more fullness.
The order comes with plastic adjustable pin hooks (for pinch pleat and tailor pleat). Plastic adjustable pin hooks allow you to adjust curtain length within 3 inches. You still need to purchase rod rings separately.
Pleats pin hooks quantity: 10 pleats for 50" width; 13 pleats for 72" width; 15 pleats for 84" width; 19 pleats for 100" width; 21 pleats for 110" width, 23 pleats for 120" width, 27 for 150" width. The width and space of the pleats may vary slightly depending on your track or pole length.
