Best Blackout Curtains 2026: NICETOWN vs Sun Zero
The phrase 'blackout' is barely regulated, so plenty of curtains sold as blackout only dim the room. The features that decide whether your bedroom actually goes dark are the fabric's layers, the header style, and — the part everyone forgets — the light that leaks around the edges no matter how good the panel is.
We compared each blackout curtain on actual light-blocking performance and fabric density, thermal insulation, noise reduction, size and colour range and fit, header style, and price. Panels were assessed against owner reviews and real-room darkening reports, weighting genuine light blocking (including the role of sizing and install) over marketing 'blackout' labels.
Nicetown Blackout Curtains
Best Overall: The NICETOWN Blackout Curtains hit the sweet spot of genuinely effective light blocking, real thermal insulation, and a huge range of sizes and colours at a fair price. Their dense triple-weave polyester blocks the large majority of light (around 85–99% depending on colour, darker blocking more) without a rubbery coating that can crack or peel, and that same density insulates against heat transfer and dampens outside noise.

Nicetown Blackout Curtains
The best all-rounder — dense triple-weave fabric blocking ~85–99% of light (no rubbery coating), real thermal insulation and noise reduction, and a huge range of sizes and colours at a fair price. The balance of performance, fit options, and value most rooms need.
The NICETOWN Blackout Curtains hit the sweet spot of genuinely effective light blocking, real thermal insulation, and a huge range of sizes and colours at a fair price. Their dense triple-weave polyester blocks the large majority of light (around 85–99% depending on colour, darker blocking more) without a rubbery coating that can crack or peel, and that same density insulates against heat transfer and dampens outside noise. The enormous selection of widths, drop lengths, and colours means you can actually get a proper fit rather than settling, and they're machine washable with a nice weight and drape, affordable enough to do a whole house. Like all panels they leak some light at the edges unless oversized, and aren't quite as total as a perfectly-installed coated blackout, but for the all-round balance most people need, they're the standout.
Pros
- ✓Dense triple-weave blocks most light, no coating to peel
- ✓Real thermal insulation and noise reduction
- ✓Huge range of sizes and colours for a proper fit
- ✓Machine washable, affordable enough for a whole house
Cons
- ✗Edge light leak unless oversized and mounted well
- ✗Not quite as total as a perfect coated/lined install
Sun Zero Grommet Blackout
The polished pick — effective room-darkening and thermal performance with clean grommet tops that hang in crisp folds and a decor-forward range of fabrics and colours. For rooms where curtains are part of the look, not just blackout equipment.
The Sun Zero Grommet Blackout curtains are the pick when you want effective blackout that also looks deliberately stylish, with clean grommet tops that hang in neat, even folds. From a well-established curtain brand, they combine solid room-darkening and thermal performance with a more refined, decor-forward range of fabrics, textures, and on-trend colours than the purely functional budget options, and the grommet header gives that crisp, tailored pleat that finishes a room. They're a strong choice for spaces where curtains are part of the decor. Depending on the fabric and colour the light-blocking may be room-darkening rather than pitch-black (lighter decorative colours block less), and they cost a little more than bare-budget panels, but for curtains that darken and insulate while genuinely enhancing the look, they're the standout.
Pros
- ✓Stylish, decor-forward fabrics and colours
- ✓Clean grommet tops hang in crisp folds
- ✓Solid room-darkening and thermal performance
- ✓Easy to match an existing scheme
Cons
- ✗Lighter colours darken rather than fully black out
- ✗Priced above bare-budget panels
Deconovo Blackout Curtains
The popular value pick — decent light blocking, a wide colour range, and some thermal and noise benefit at an attractive price. A frequent best-seller that looks nice and performs respectably for bedrooms, nurseries, and rentals.
The Deconovo Blackout Curtains are a popular value pick balancing decent light blocking, a wide colour range, and an attractive price. They use a coated or densely-woven blackout fabric that darkens a room well, come in many colours and sizes including grommet styles, and offer some thermal and noise benefit. They're a frequent best-seller for good reason — they look nice, perform respectably, and cost little — making them sensible for bedrooms, nurseries, and rentals where you want effective darkening without overspending. Performance is good rather than premium, and the very darkest rooms or harshest sun will reveal the gap to heavier thermal panels, but for the money, they're a smart, attractive choice.
Pros
- ✓Good room-darkening at an attractive price
- ✓Wide colour range, including grommet styles
- ✓Some thermal and noise benefit
- ✓Popular, well-reviewed best-seller
Cons
- ✗Good rather than premium performance
- ✗Lighter than dedicated thermal panels
H Versailtex Blackout
The thermal-insulation specialist — heavier, often thermal-lined construction engineered to block heat transfer (cooler in summer, warmer in winter, lower bills) plus strong light blocking and noise reduction. The pick for drafty or sun-baked windows.
The H.VERSAILTEX is the thermal-insulation specialist for someone whose priority is energy saving and temperature control as much as darkness. Many of its panels use a heavier, often microfiber or thermal-lined construction engineered specifically to block heat transfer through the window — keeping rooms cooler in summer and warmer in winter and cutting energy bills — alongside strong light blocking and noticeable noise reduction, since the denser, heavier fabric naturally blocks light and sound better than thin panels. It's the pick for drafty windows, hot west-facing rooms, or anyone who wants insulation as a primary feature rather than a bonus. The heavier fabric is less airy and the range is more function-led than decor-led, but for thermal performance plus darkness, it leads here.
Pros
- ✓Heavier thermal-lined fabric blocks heat transfer
- ✓Cuts energy bills on drafty or sunny windows
- ✓Strong light blocking and noise reduction
- ✓Ideal for hot or cold problem rooms
Cons
- ✗Heavier, less airy fabric
- ✗More function-led than decorative range
Amazon Basics Blackout Curtains
The no-frills budget champion — simple, effective room-darkening panels at the lowest price in common sizes and basic colours. Narrower range and lesser fabric than premium options, but the obvious cheap choice for guest rooms, kids' rooms, and rentals.
The Amazon Basics Blackout Curtains are the no-frills budget champion — simple, effective room-darkening panels at the lowest price, in the common sizes and a range of basic colours, with a straightforward grommet top. They block a good amount of light and add modest insulation. They won't match the fabric quality, total darkness, or thermal performance of the premium options, and the size and colour range is narrower, but for kitting out a guest room, a kid's room, or a rental cheaply, or as a baseline that simply works, they're the obvious low-cost choice. Pair them with generous sizing and a high, wide rod mount and even these inexpensive panels darken a room respectably.
Pros
- ✓Lowest price, effective room-darkening
- ✓Common sizes and basic colours
- ✓Simple grommet top
- ✓Great for guest rooms, kids' rooms, rentals
Cons
- ✗Lesser fabric and thermal performance
- ✗Narrower size and colour range

Top pick: NICETOWN Blackout Curtains
The NICETOWN Blackout Curtains are the best for most rooms because they hit the sweet spot of genuinely effective light blocking, real thermal insulation, and a huge range of sizes and colours at a fair price. They use a triple-weave fabric — a dense, tightly-woven polyester that blocks the large majority of light (NICETOWN cites blocking around 85–99% depending on colour, with darker colours blocking more) — without a rubbery coating that can crack or peel over time. The same density that blocks light also insulates, cutting heat transfer through the window in summer and winter, and dampens outside noise noticeably.
What makes them the default is selection and value. NICETOWN offers an enormous range of widths, drop lengths, and colours, so you can actually get a proper fit for your specific window rather than settling for 'close enough,' and they come in both grommet (eyelet) and other header styles. They're machine washable, hang with a nice weight and drape, and are priced affordably enough to do a whole house. For a balance of true blackout performance, insulation, fit options, and price, they're the standout.
The honest caveats: like nearly all curtains, no panel blocks 100% of light on its own — some will leak around the edges unless you size up and overlap (see the buying guide) — and the very darkest rooms need the panels paired with a wraparound or ceiling-mounted track. The triple-weave is excellent but not quite as absolutely total as a coated/lined blackout in a perfect install. But for the best all-round combination most people need, NICETOWN is the easy recommendation.
Best for a polished look: Sun Zero Grommet Blackout
The Sun Zero Grommet Blackout curtains are the pick when you want effective blackout that also looks deliberately stylish, with clean grommet (eyelet) tops that hang in neat, even folds. Sun Zero is a well-established curtain brand, and these combine solid room-darkening and energy-saving (thermal) performance with a more refined, decor-forward range of fabrics, textures, and on-trend colours than the purely functional budget options. The grommet header slides smoothly on a rod and gives that crisp, tailored pleat that makes a room look finished.
They're a strong choice for living rooms, bedrooms, and spaces where the curtains are a visible part of the decor rather than purely utilitarian — you get genuine light reduction and insulation without the curtains looking like blackout 'equipment.' The quality of the fabric and the hang is a step up in presentation, and Sun Zero's range makes it easy to match an existing scheme.
The trade-offs: depending on the specific fabric and colour, the absolute light-blocking may be room-darkening rather than total pitch-black (lighter, more decorative colours block less light than dense dark ones), and they're typically priced a little above the bare-budget options. If your single priority is a completely black room at any aesthetic cost, a denser dark panel does more; but if you want curtains that darken and insulate while genuinely enhancing the room's look, the Sun Zero Grommet is the standout.

How to choose: real blackout, fit and edges, thermal, and header style
Understand that 'blackout' is a loose term and judge the fabric. Truly dark-the-room panels use either a dense triple-weave fabric (NICETOWN) or a coated/lined fabric, and darker colours always block more light than lighter ones (a white 'blackout' curtain blocks far less than a navy or charcoal one of the same line). Check the manufacturer's stated light-blocking percentage and read reviews for whether buyers say their room went genuinely dark. If you need total darkness for shift-sleeping or a nursery, prioritise the densest, darkest panels and accept that lighter decorative colours are room-darkening rather than blackout.
Size up and plan for edge leak, because that's where most 'blackout failure' actually comes from. Even a perfect panel leaks light around the sides, top, and bottom if it's the exact size of the window — so to genuinely darken a room you want curtains significantly wider than the window (so they overlap in the middle and wrap toward the wall) and longer than the opening (puddling at the floor or mounted high and wide). Mounting the rod high and extending it well past the window frame on both sides, or using a wraparound/ceiling track, dramatically reduces edge leak. The panel matters, but the install and oversizing matter just as much for a truly dark room.
Decide how much you value thermal and noise benefits, and pick a header style. Denser, heavier panels (H.VERSAILTEX thermal, NICETOWN triple-weave) don't just block light — they insulate against heat loss and gain (saving energy on drafty or sun-baked windows) and dampen outside noise, which is a real bonus for street-facing or hot rooms. If energy or quiet is a priority, weight the fabric heaviness. Finally, match the header: grommet/eyelet tops (common across these) slide easily and give clean folds on a rod, rod-pocket tops give a gathered look, and tab or pinch-pleat styles suit different decor — choose the one that fits your rod and the look you want, and confirm the panel width is generous enough for nice fullness rather than a stretched, flat hang.
