Curtain Size Guide: 5 ft vs 7 ft vs 9 ft, and How Many Panels Per Window (India)

Short answer: Buy 5 ft (152 cm) curtains for a standard window, 7 ft (213 cm) for a standard door, and 9 ft (274 cm) for a tall door or a window you want to cover floor-to-ceiling. Measure the drop from the curtain rod down, not from the top of the window frame. For width, the curtains together should be 1.5 to 2 times the rod width. On a typical 4–5 ft window that means two 4 ft panels.

Most sizing mistakes happen because people measure the glass instead of the rod, or buy one panel when the window needs two. The chart below fixes both.

Curtain size chart (India)

Curtain length In cm Fits Where the hem ends
5 ft ~152 cm Standard window (about 4 ft tall) with the rod 15 cm above the frame Just below the sill
6 ft ~183 cm Window that sits low on the wall, or a long window Halfway to the floor or below
7 ft ~213 cm Standard door (about 7 ft frame), rod fixed just above it A few cm off the floor
8 ft ~244 cm Door with the rod placed higher, or a balcony door Floor-touching
9 ft ~274 cm Tall door, French window, or rod mounted near the ceiling Floor-touching on a 9–10 ft ceiling

Indian sellers list curtains by length in feet and almost always sell panels about 4 ft (120–135 cm) wide. That width is fixed, so you choose the length and then decide how many panels to buy.

How to measure in 3 steps

1. Fix the rod position first

Mount the rod 10–15 cm above the window frame, and extend it 15–20 cm past each side of the frame. The extra height makes the window look taller. The extra width lets the open curtains rest on the wall instead of over the glass, so you get the full daylight.

If the rod is already up, measure from it as it is.

2. Measure the drop

The drop runs from the rod (or from the eyelet ring line) down to where you want the hem to end:

  • Sill length: end 1 cm above the sill. Good for kitchens and for windows with a sofa or bed under them.
  • Below sill: end 10–15 cm below the sill. It looks fuller and still clears furniture.
  • Floor-touching: end 1–2 cm above the floor. This is the cleanest look for doors and living rooms.

Round down to the nearest stock size, never up. A curtain that drags on an Indian floor picks up dust within a week and wears at the hem.

Eyelet vs rod-pocket: with eyelet (grommet) curtains, the fabric rises about 3–5 cm above the rod. Measure from the top of the rod, then remember the hem will sit that much higher. Rod-pocket and tab-top curtains hang from the rod line itself.

3. Measure the rod width

Measure the full rod between the finials (the decorative end caps). This number decides how many panels you need.

How many curtain panels per window?

Fullness is the ratio of total curtain width to rod width:

  • 1.5Γ—: neat and light, with fewer folds. Fine for sheer curtains and rentals.
  • 2Γ—: the standard, full look. Use it for blackout and living-room curtains.
  • 2.5–3Γ—: heavy folds; you only need this for very thin fabric.

Formula: panels = (rod width Γ— fullness) Γ· panel width, rounded up.

Rod width At 1.5Γ— fullness (4 ft panels) At 2Γ— fullness (4 ft panels)
3 ft (small window) 2 panels 2 panels
5 ft (standard window) 2 panels 3 panels (or 2 if you accept lighter folds)
6 ft (wide window) 3 panels 3 panels
8 ft (balcony door) 3 panels 4 panels
10 ft (sliding door) 4 panels 5 panels

Buy in pairs when the window opens from the middle. A single panel works only for a narrow door or a side-draw window.

Blackout vs room-darkening vs sheer

Pick the fabric before you pick the size, because it changes how much fullness you need.

Type Blocks light Best room Note
Blackout ~90–100% Bedroom, home theatre, night-shift sleeper Thick and heavy. 2Γ— fullness hangs best. Adds a little heat insulation.
Room-darkening ~70–90% Bedroom, kids' room Lighter than blackout, so it is easier to wash.
Semi-sheer Partial Living room, study Softens the glare but keeps the room bright.
Sheer Little Living room as a day layer Privacy only in daylight. At night it shows silhouettes.
Cotton Medium Doors, kitchens, humid rooms Breathes well and washes easily. It can shrink 2–3% on the first wash.

The double-rod trick: a sheer layer behind a blackout layer gives you daytime privacy and night-time darkness from one window. You need a double bracket, or two rods 8–10 cm apart.

Tips for Indian homes

  • Dust and humidity: polyester blackout fabric resists mildew better than cotton in the monsoon. Wash curtains every 2–3 months in a gentle cycle. Hang them back on the rod while slightly damp so the creases fall out.
  • West-facing windows: the afternoon sun fades prints fast. A blackout or lined curtain protects the furniture and keeps the room cooler.
  • Rentals: you usually can't drill new holes. Use the existing rod, choose eyelet curtains (they slide easily on any rod), or use an extendable tension rod inside the window recess.
  • Rings and hooks: rust is the most common failure on rods near bathrooms and balconies. Stainless steel rings outlast painted iron.
  • Shrinkage: if the curtain is 100% cotton, buy a length that ends 2–3 cm lower than you want. The first wash pulls it up.

Frequently asked questions

What size curtain is right for a normal window in India?

A 5 ft (152 cm) curtain fits most standard windows, which are about 4 ft tall, when the rod is mounted 10–15 cm above the frame. If the window sits low on the wall or you want the hem well below the sill, choose 6 ft.

Is a 7 ft curtain right for a door?

Yes. A standard Indian door frame is about 7 ft tall. A 7 ft curtain on a rod fixed just above the frame ends a few cm off the floor. If the rod is higher, move up to 8 or 9 ft.

How many curtains do I need for one window?

Most 4–5 ft wide windows need two 4 ft panels. To get the exact number, multiply the rod width by 1.5 for a light look or by 2 for a full look, divide by the panel width, and round up.

Should curtains touch the floor?

For doors and living rooms, a hem 1–2 cm above the floor looks cleanest and stays clear of dust. Puddled curtains (10–15 cm on the floor) collect dirt quickly in Indian homes, so avoid them unless the floor is carpeted and rarely mopped.

Blackout or room-darkening, which is better for a bedroom?

Blackout blocks nearly all light, which suits day sleepers and home theatres. Room-darkening blocks most light, weighs less and is easier to wash, so it is enough for most bedrooms where the goal is simply a darker room in the morning.
