Finished curtain width, flat fabric width, and panel quantity describe different parts of an order. The finished width refers to the completed panel under the product's sizing convention; flat fabric is the material before gathering or pleating. Confirm what the selected header's width field means and whether the listed item is one panel or a pair before calculating quantities.
How do finished width and flat fabric width differ?
For a sewn-pleat curtain, fabric is taken into permanent folds, so the flat fabric width and the completed pleated width are different measurements. Other headers may use a different ordering convention. Read the selected product's width instructions with its header choice; do not substitute the width of loose fabric for a requested finished width, or the reverse.
The visible width in a styled photograph is not a reliable order dimension either. A panel shown open is stacked, while a closed panel may still contain folds. Neither image tells you how the ordering field is defined.
Avoid adding fullness twice
Fullness describes the relationship between fabric and the area it covers. It is not an automatic multiplier to apply to every product's width field. If the stated finished width already accounts for a sewn-pleat construction, applying a separate generic fabric multiplier can produce an order that is not what you intended.
Use the header-style guide and the selected product's instructions to establish the sizing convention first. If the wording is unclear, ask which dimension you should submit rather than calculating from a rule found for a different header.
Separate coverage from quantity
- Hardware or coverage span: the area your planned arrangement needs to serve.
- Width per ordered item: the dimension entered for the selected panel or product unit.
- Number of items: how many of those units you are purchasing.
A curtain panel is one separate hanging curtain; a pair contains two panels. The cart quantity, however, counts the product units being sold. If a listing sells individual panels, one unit means one panel; if it explicitly sells a pair, one unit means that pair. Check the product page, selected options, and cart together instead of inferring quantity from a photograph.
Write the arrangement in plain language
Instead of recording only a width, write something like: “Two panels for this window, meeting at the center; each panel has its own confirmed finished width.” This is a layout description, not a sizing formula. Add the actual dimensions only after following the applicable measuring instructions.
For a one-sided opening, note which side the fabric rests on and confirm the hardware can support the intended movement. A center support, return, or overlap may introduce additional considerations that should be resolved with the chosen system.
Review the selected product, not a generic example
When considering Sedona Linen Blend Drapery Soft Top, keep the chosen header visible as you review width and quantity. Compare options in the Linen Curtains collection only after you understand how each relevant product is ordered.
Follow the drapery measuring guide for the final measurements. Before checkout, confirm the window label, header, width convention, length reference, lining, and quantity. If two people would interpret that record differently, the order needs one more clarification.
