Will these curtains actually fit the window?
Two numbers decide it: how wide the fabric is against the opening, and how far the hem falls. Both are printed with the arithmetic that produced them. Nothing to sign up for.
Your measurements
Pre-filled with a real failing example: a 74 in window with its top 92 in above the floor, dressed with two 42 × 63 in panels. Edit any field.
Result
Verdict: too short and too narrow
2 × 42 in = 84 in ÷ 74 in = 1.14×. Gathered curtains normally want 1.5×–2.5×.
92 in + 0 in = 92 in above the floor
92 in − 0 in = 92 in for the "to the floor" look (hem target 0 in above the floor).
92 in − 63 in = 29 in short; the hem ends 29 in above the floor
These results are arithmetic on the numbers you entered — nothing is measured for you and nothing here is a guarantee that an item will fit. Delivery paths are not checked: stairs, hallways, lifts and doorway routes can stop an item that fits the room perfectly. Fabric weight, header style and hardware projection change how a panel hangs; only the measured width and drop are computed here.
Common questions
- How much fullness do curtains need?
- Gathered curtains normally want 1.5× to 2.5× the window width in flat fabric. Total panel width divided by window width gives the fullness ratio; below 1.5× the panels read flat rather than gathered.
- How do I work out the curtain drop?
- Rod height is the floor-to-top-of-window measurement plus how far above the window the rod sits. The required drop is that rod height minus the height you want the hem to finish at: the sill, just below the sill, the floor, or slightly below the floor for a puddle.
- Why do 63 inch panels look short?
- If the rod sits 92 inches above the floor and you want the hem at the floor, the panel must drop 92 inches. A 63 inch panel finishes 29 inches above the floor, which reads as a short curtain no matter how wide it is.
What this did not check
This page only did the arithmetic above. It did not look at:
- Whether the curtain or its rod fouls a door swing, a wardrobe door, or anything else that opens near the window.
- The walkway in front of the window once a panel is hanging, and how far the stack of gathered fabric intrudes when the curtains are open.
- Collisions with anything else you are buying — a bed, a desk or a radiator cover under the window is not modelled here.
- The delivery path — stairs, hallways, lifts, turns and doorway routes are not measured here, and they stop more purchases than room size does.
