Rod or track?
Compare visible poles, wall/ceiling tracks, frequent opening, layering and special shapes before you choose the hanging system.
Compare rod vs trackCurtain planning library
Plan the whole curtain setup — not just the size
Curtain buying is a chain of decisions: what hardware can fit, how the curtain attaches, how it should move, what the fabric needs to do and whether the opening has special geometry. Start with the decision you are actually trying to make.

Which decision comes next?
Each guide answers a different planning problem. There is no need to read them in order.
How should the curtain attach?
Eyelet, rod pocket, back tab, pencil pleat, pinch pleat and wave/ripplefold do not use hardware in the same way.
Compare heading typesHow dark should the room get?
Separate light-filtering, room-darkening and blackout goals, then account for the gaps around the curtain as well as the fabric.
Compare light controlHow should the curtain behave?
Compare sheer, linen, cotton blends, polyester, velvet and lined constructions by drape, weight, care and the job they need to do.

Daily access changes the plan. Decide stack side, opening direction, floor clearance and whether a track makes more sense.
Plan a sliding doorBay window?
Measure each segment, decide whether curtains turn the corners or stay on separate sections and verify compatible corner hardware.

How to measure for curtains
Capture window width, free wall on both sides and planned rod-to-floor height with a worksheet that sends values into the calculator.
Open measuring guideCurtain width & fullness
Understand target fabric width, whole-panel rounding and why actual fullness changes after you buy complete panels or packs.
Open fullness guideReady-made curtain lengths
Compare common listed lengths with the rod-to-floor drop you actually measured and the finish you want at the floor.
Open length guideCalculate, do not guess
Use Nenxo’s main calculator when you want rod width, panel count, finished drop, wall-fit warnings and ready-made product comparison together.
Open curtain size calculatorA practical order for a new room
- Read the opening: ordinary window, door, corner/bay, obstacles and daily access.
- Choose hardware family: rod/pole, track/rail or a product-specific system.
- Choose a compatible heading: this affects how the fabric attaches, moves and where the finished drop is measured from.
- Choose performance: daylight, privacy, darkness, drape, weight and care.
- Measure and calculate: only now turn the room geometry into rod span, panels and length.
- Verify the exact product: pack contents, heading construction, hardware dimensions, support instructions and care label.
Three planning mistakes this library is designed to prevent
Buying fabric before hardware
A heading can look perfect online and still be unusable on the rod or track already in the room. Compatibility comes before colour or price.
Using one rule for every opening
A normal window, a patio door and a bay window ask different questions about movement, corners and stack space. Treat the geometry first, then calculate size.
Assuming a label is a measurement
“Blackout,” “room darkening,” “96 inch” and even “pair” need product-level verification. Nenxo keeps the exact specification separate from the general planning guide.
Solving width but ignoring use
A curtain can mathematically cover an opening and still block a doorway, catch on a handle or stack over too much glass. The guide pages add those real-room checks.
How the guides connect back to the tools
The guide library narrows the decisions the calculators cannot know: hardware family, heading, light-control goal, fabric behavior and special-window layout. Once those choices are made, the calculators take over the arithmetic. This separation keeps Nenxo useful without inventing a “perfect” curtain from inputs that do not describe the room.
Why Nenxo separates these topics: a mathematically correct panel count can still produce the wrong purchase if the heading does not fit the hardware, a sliding door cannot open comfortably or a blackout panel leaves large light gaps. The guides cover those decisions without pretending one setup is universal.
