Why Curtain Size Matters More Than You Think
The wrong curtain size can make your room feel cramped, unfinished, or awkward. A curtain that's too short looks like it shrank in the wash. Too narrow, and it won't cover your window properly. Getting the size right is the single most important step when buying curtains — more important than colour or fabric.
This guide covers everything you need to know about measuring windows and choosing curtain dimensions for Indian homes.
Step 1: Measure Your Window Width
Measure the full width of your window frame — not just the glass. Include the frame edges on both sides.
The Fullness Rule
For a proper gathered look, your curtain width should be 1.5x to 2.5x the window width:
- Minimal fullness (1.5x): Clean, modern look — works well with linen and cotton curtains
- Standard fullness (2x): Most popular choice for living rooms and bedrooms
- Luxurious fullness (2.5x): Rich, dramatic folds — ideal for velvet and heavy fabrics
Example: If your window is 150 cm wide, you need a total curtain width of 225–375 cm (split across two panels).
Step 2: Choose Your Curtain Length
There are four standard curtain lengths used in Indian homes:
1. Sill Length
The curtain ends exactly at the window sill. Best for kitchens and bathrooms where you need easy access below the window.
2. Below Sill (Apron Length)
Hangs 10–15 cm below the sill. Works well for casual spaces and windows above furniture like a sofa or desk.
3. Floor Length
The curtain stops 1–2 cm above the floor. This is the most recommended length for living rooms and bedrooms. It looks clean, polished, and prevents dust accumulation.
4. Puddle Length
Extra 5–15 cm of fabric pools on the floor. Creates a luxurious, romantic look — best for master bedrooms and formal rooms. Requires heavier fabrics like velvet or silk.
Step 3: Rod Placement
Where you mount the curtain rod dramatically affects how your room feels:
- Mount 15–20 cm above the window frame — this makes ceilings appear taller
- Extend the rod 15–20 cm beyond each side — makes windows appear wider and lets maximum light in when curtains are open
For standard Indian windows (120–150 cm wide), a rod width of 150–190 cm is ideal.
Quick Size Chart for Indian Homes
Here's a ready reference based on common Indian window sizes:
| Window Width | Curtain Width (2x) | Rod Width |
|---|---|---|
| 90 cm | 180 cm (2 panels of 90 cm) | 120–130 cm |
| 120 cm | 240 cm (2 panels of 120 cm) | 150–160 cm |
| 150 cm | 300 cm (2 panels of 150 cm) | 180–190 cm |
| 180 cm | 360 cm (2 panels of 180 cm) | 210–220 cm |
Common Curtain Size Mistakes
- Buying the exact window width: Your curtains will look flat and won't gather properly
- Hanging too low: Mounting the rod at the window frame instead of above it makes the room feel shorter
- Ignoring the gap: Floor-length curtains should hover 1–2 cm above the floor, not drag on it (unless you want the puddle look)
- Mismatched panels: Both panels should be identical in width for a balanced look
Fabric Affects Size Choice
Your fabric weight influences the best fullness and length:
- Sheer/lightweight (cotton voile, organza): Use 2.5x fullness for a soft, flowing look
- Medium weight (cotton, linen, polyester blend): Standard 2x fullness works perfectly
- Heavy (velvet, jacquard, blackout): 1.5–2x fullness is enough — too much fabric creates bulk
FAQs
What size curtains do I need for a standard Indian bedroom window?
Most Indian bedroom windows are 120 cm wide. You'll need curtains with a total width of 240 cm (two panels of 120 cm each) and a length of 210–230 cm for floor-length.
Should curtains touch the floor?
Floor-length curtains should stop 1–2 cm above the floor. This gives a clean, tailored look without dragging dust. Puddle-length curtains that rest on the floor are a style choice for formal rooms.
How do I measure for curtains if I don't have a rod yet?
Measure your window frame width, add 30–40 cm for rod extension, and measure from 15–20 cm above the window frame down to your desired length (sill, floor, or puddle).
