Curtain width: per panel or per pair?
Last reviewed October 21, 2026
A curtain listing that says "52 in W" may mean each panel is 52 inches wide, or that two panels together measure 52 inches. Listings are not consistent, so check which one you are reading before you count panels.
The short answer
- A panel is one curtain. A pair, set of 2 or 2-pack is two panels sold together.
- The width on a listing is the flat width: the fabric laid out, before it is gathered on the rod.
- That width can describe one panel or the whole pack. The listing usually tells you somewhere, but not always in the title.
Where to look on a listing, in order
- The size line. Look for "each", "per panel" or "panel size" next to the width. "52 in W x 84 in L (each panel)" means one panel.
- The specifications. Find the number of panels and a separate panel width. If they are given, the title width is either that panel width or the panels added together.
- Do the check. If the title width equals the panel width times the number of panels, the title gives the width of the whole pack.
- The package or label. In a store, read what the package states: the number of panels and the size, and whether that size is per panel.
- Still unclear? Ask the seller, read the product questions, and check the return policy before you buy several packs.
Three example listings, decoded
These listings are invented for illustration. Each is worked out for the same window: a 76 in rod span, fullness 2 (so 152 in of flat fabric), curtains opening in the middle.
Example A
Listing text: "Linen-look grommet curtains, set of 2 panels. Size: 52 in W x 84 in L (each panel)."
The listing says "each panel", so 52 in is the width of one panel and the pack has 2.
- Width of one panel
- 52 in
- Panels to hang
- 4
- Packs to buy
- 2 (4 panels)
- Spare panels
- 0
- Fullness when hung
- 2.74×
Example B
Listing text: "Blackout curtain pair. Size: 104 in W x 84 in L. Specifications: 2 panels, panel width 52 in."
The specifications give 52 in per panel, so the 104 in in the title is the width of the pair together.
- Width of one panel
- 52 in
- Panels to hang
- 4
- Packs to buy
- 2 (4 panels)
- Spare panels
- 0
- Fullness when hung
- 2.74×
Example C
Listing text: "Sheer voile panel, 54 x 95 in. Sold individually."
One panel per pack, so the width and the pack are the same thing.
- Width of one panel
- 54 in
- Panels to hang
- 4
- Packs to buy
- 4 (4 panels)
- Spare panels
- 0
- Fullness when hung
- 2.84×
Examples A and B describe the same panels in two different ways, and they give the same plan. Example C sells panels one at a time: 4 panels hung means 4 packs.
What a misread costs
Suppose you read example B's "104 in W" as the width of one panel. You would think 2 panels (1 pack) are enough. In fact each panel is 52 in, so those 2 panels give 1.37× fullness instead of the 2× you wanted: the curtains would look much flatter than planned, and you would need 2 packs, not 1.
Flat width is not the width covered
Gathered curtains cover less than their flat width. Fullness compares the two: two 52 in panels (104 in flat) on a 76 in rod give 1.37×. How full curtains should look is a style choice; retailer guidance such as IKEA's suggests multiplying the rod width by 2, or by 2.5 for a fuller look. With a middle opening, each side covers about half the rod.
