Five details that decide whether blackout curtains work
1. Liner
A sewn or bonded black liner blocks more light through the fabric than an unlined decorative panel. This matters most when you want a light exterior color.
2. Total width
Add both panels together. Aim for enough fabric to cover the window and overlap at the center instead of stretching the set flat.
3. Side coverage
Extend the rod past the window trim so each panel can cover the bright vertical edge. Wraparound rods can reduce that gap further.
4. Top and bottom gaps
Mounting the rod above the trim and choosing enough length reduces the bands of light that appear over and under the fabric.
5. Care
Blackout liners can have different wash rules than ordinary curtains. Follow the exact label to protect the bonded or sewn layers.
6. Exact variant
Size and color selections can change fabric behavior and listing terms. Confirm the exact option after opening the seller page.
NICETOWN vs Deconovo blackout curtains
| Literal difference | NICETOWN linked model | Deconovo linked model | Why it matters |
|---|---|---|---|
| Exact variant | Pure White, two 52 × 84-inch panels | Black, two 52 × 63-inch panels | Length must match the window and mounting height; excess or missing length changes coverage. |
| Light-blocking layer | Black liner sewn behind triple-weave fabric | Bonded black liner behind high-density fabric | Both add a dark barrier behind the face fabric. Edge gaps still need to be covered. |
| Care | Seller advises limited washing and cold hand wash when needed | Machine wash cold and tumble dry low | Deconovo is the easier choice when regular washing is part of your routine. |
| Certification listed | No textile certification used in our recommendation | OEKO-TEX Standard 100 listed for the exact model | The certification addresses tested textile substances; it does not measure bedroom darkness. |
Best 84-inch lined pick
NICETOWN 100% Blackout Curtain Panels
The linked set includes two Pure White panels, each 52 inches wide and 84 inches long, backed by a black liner. The main reason to buy this model is getting a light face color without giving up the dark layer behind it.
Who benefits: renters, shift workers, nurseries, and bedrooms that need a common 84-inch panel length. Measure the width and leave room for center overlap.
Choose the other model if: you need 63-inch panels or machine-washable care.
Best shorter easy-care pick
Deconovo 100% Blackout Curtains
The linked set includes two Black panels, each 52 inches wide and 63 inches long, with a bonded black liner. Its practical upgrade is care: the exact model is listed as machine washable in cold water and tumble-dry low.
Who benefits: bedrooms with shorter windows, households that want easier laundering, and shoppers who prefer black panels.
Choose the other model if: your rod placement requires the longer 84-inch drop or you prefer Pure White face fabric.
For maximum darkness, combine room and personal light control
Curtains handle the entire window and preserve a dark room when you move around. A contoured sleep mask covers the narrow edge and top gaps that remain. Shift workers and sleepers with streetlights near the window may get a stronger result from both than from buying a heavier curtain alone.

Frequently asked questions
Do blackout curtains block 100% of bedroom light?
A lined fabric can block light through the panel while light still enters above, below, or beside it. Panel overlap, rod placement, window width, and curtain length determine the result in the room.
What is the difference between blackout and room-darkening curtains?
Blackout products use denser fabric or an added liner to block more light through the panel. Room-darkening curtains reduce light but may leave a visible glow, especially in light colors.
How wide should blackout curtains be?
A practical target is a combined panel width around 1.5 to 2 times the window width, plus enough side coverage to overlap the trim. Follow the exact product's measuring guide because fullness and mounting style vary.
Are blackout curtains useful for shift workers?
They can make a daytime bedroom darker when sized and mounted to cover the full window. A sleep mask can cover remaining edge light without requiring a second curtain layer.
