84, 96, 108 or 120 inch curtains?
Start with the distance from the planned top of your rod or track to the floor. A ready-made number is useful only after you know the target length for your actual room.
Common ready-made lengths are reference points, not room measurements
You may encounter curtains labelled 84, 96, 108 or 120 inches. Treat those as product options, not as a reason to place the rod at a matching height. Measure the room and hardware position first, then compare the result with the sizes sold by the product you want.
| Listed curtain length | Approx. centimetres | Planning use |
|---|---|---|
| 84 in | 213.4 cm | Compare only if your measured target is near this drop. |
| 96 in | 243.8 cm | A product option for rooms whose hardware-to-floor target is close. |
| 108 in | 274.3 cm | Useful to compare for taller mounting positions. |
| 120 in | 304.8 cm | Another long ready-made option; verify the exact product listing. |
Brands and markets do not all offer the same size set, so Nenxo does not maintain a “standard size” database. The product comparison uses the length printed on the listing you are considering.
Measure from the planned hardware — not automatically from the window top
The top reference depends on how the curtain hangs. A rod with rings, an eyelet panel and a ceiling track can put the fabric start point in different places. Use the reference specified for your actual heading and hardware, then measure down to the finished floor.
Choose how the curtain should meet the floor
These are transparent calculator allowances, not universal workroom standards. Change the input if your curtain maker or hardware system specifies a different reference.
Too short and too long are not equivalent problems
A panel shorter than the target cannot become longer through hemming. A longer ready-made panel may be alterable, depending on the fabric, heading and construction. Nenxo therefore flags a short product rather than pretending it can be “close enough”.
When floor-length logic should not be used blindly
Radiator or heat source
Do not cover a heat source just because the calculator produced a floor-length result. Follow the appliance and curtain manufacturer guidance and choose a safe finished length.
Uneven floor
Measure more than one point across a wide opening. The shortest or longest practical drop may control the final decision.
Ceiling track
Use the track or heading reference that determines where the fabric actually begins, not the top edge of the window.
Several different windows
Use the room planner so each opening keeps its own rod-to-floor target instead of sharing one length.
Check the exact product you found
Enter the listed panel length in the Nenxo product comparison. It will show whether the product is short, near target or longer than the measured drop.
