Curtains are the largest soft surface in most rooms — and the most commonly wrong. Hung too low, cut too narrow, in fabric that fades by Diwali. Get them right and ceilings look higher, rooms look wider and afternoons get cooler; the formulas below are exactly what a good designer uses, translated into buyable numbers.
The two measurements that change everything
Height: mount the rod 6–8 inches ABOVE the window frame (or at the ceiling line / inside a pelmet), and let curtains fall to half an inch above the floor. This one change makes an 9.5-ft room read 10.5 ft. Curtains that stop at the sill or hover mid-wall visually chop the room — the single most common Indian curtain mistake.
Width (fullness): total fabric width = 2 to 2.5× the rod width. A 5-ft window wants 10–12 ft of fabric across its panels. Flat, stretched curtains scream budget regardless of fabric price; generous gathering makes even plain cotton look tailored. Extend the rod 6–10 inches beyond the frame each side so open curtains stack on wall, not glass — the window looks bigger and you keep every inch of light.
Fabric for Indian light, heat and dust
| Fabric | ₹/metre | Best for | Watch out |
|---|---|---|---|
| Cotton/cotton-blend | ₹150–500 | Everyday rooms; washes easily | Fades in strong sun; line them |
| Sheers (net/voile) | ₹100–350 | The privacy + light layer | Pair with a main curtain |
| Polyester blends/jacquard | ₹200–600 | Fade-proof workhorses | Cheap ones look shiny |
| Linen/linen-look | ₹400–1,200 | The premium drape | Real linen creases; blends behave |
| Velvet | ₹500–1,500 | Bedrooms, drama, insulation | Dust magnet — vacuum monthly |
| Blackout (3-layer weave) | ₹350–900 | Bedrooms, west windows | "Room darkening" ≠ blackout — check the label |
The designer's default: double rod, sheer + main curtain. Sheers give daytime privacy with full light; the main layer handles evenings and heat. This combination alone upgrades every room it enters.

Blackout, honestly
True blackout is a 3-layer weave (or a lining layer) that blocks 95%+ light — transformative for sleep and for west-facing rooms where it cuts afternoon heat noticeably. "Room darkening" polyester at half the price blocks 60–80%: fine for living rooms, disappointing in bedrooms. Test in the shop: phone-torch against the fabric tells the truth instantly. Our bedroom guide ranks blackout curtains among the best sleep investments in the house.
Headers, rods and the pelmet question
- Eyelet: the Indian default — clean waves, slides easily, needs a round rod.
- Pleated (pinch/pencil): the tailored premium look, needs hooks-and-track or rings; costs more to stitch, drapes best.
- Rod pocket: avoid for daily-use curtains — drags and tears.
- Tracks + pelmet/cove: the luxury move — curtains glide on a concealed ceiling track behind a pelmet with warm LED strip inside. Plan it with the false ceiling.
- Rods: ₹500–2,500 per window in wood/metal finishes; extend brackets clear of the frame; double brackets for the sheer layer.
What it costs, per window (2026 indicative)
| Setup | Typical total |
|---|---|
| Ready-made pair + basic rod | ₹1,200–3,000 |
| Custom-stitched cotton + sheer + double rod | ₹3,500–7,000 |
| Blackout + sheer, pleated on track with pelmet | ₹7,000–15,000 |
Stitching runs ₹100–300 per panel; measure AFTER flooring is done, and order all rooms from one fabric batch — dye lots differ just enough to notice.
Frequently asked questions
How high should curtains be hung?
Rod 6–8 inches above the window frame (or at ceiling height), fabric ending half an inch above the floor. High-and-long makes rooms read taller — sill-length curtains shorten them.
How much fabric do I need for curtains?
Total width 2–2.5× the rod length, split into panels. A 5-ft window needs 10–12 ft of fabric width plus 8–10 inches of drop margin for hems and header.
Which curtain fabric is best for Indian summers?
A sheer + blackout double layer: sheers for daytime light with privacy, the 3-layer blackout drawn against the western sun cuts real heat. Polyester blends resist fading best.
What is the difference between blackout and room-darkening?
Blackout (3-layer weave or lined) blocks 95%+ light; room-darkening blocks 60–80%. The phone-torch test through the fabric settles any label's claim.
Eyelet or pleated curtains — which is better?
Eyelets are practical and modern on rods; pinch pleats on tracks drape more formally and suit pelmets. Choose by hardware: rods → eyelets, concealed tracks → pleats.
What do custom curtains cost in India?
₹3,500–7,000 per window for stitched cotton with a sheer layer and double rod; ₹7,000–15,000 for blackout with pleats, track and pelmet (2026 indicative, fabric-dependent).
