Best Blackout Curtains Under $25 (2026)

On a page capped at $25, the NICETOWN Black 42x63 at $9.98 for two panels is exceptional value — two blackout curtain panels for under $10. At roughly $5 per panel, this undercuts the next option on this page (the Grey 52x63 at $16.80) by $7 while still delivering the triple-weave construction NICETOWN built its reputation on. The trade-off is the 42" width, which is 10" narrower than the Grey panels; for windows up to 36" wide one 42" panel covers adequately, but standard 40-48" windows benefit from two panels per window, which keeps the per-window cost at $20. The black colorway maximizes darkness by absorbing ambient light that sneaks in at the edges rather than reflecting it back into the room — a meaningful advantage for shift workers sleeping during daylight or rooms near outdoor lighting. The grommet top with 6 rings per panel installs in under 5 minutes on a standard rod. The thermal backing layer provides basic insulation alongside the blackout function. Best for anyone needing functional blackout curtains on a tight budget, especially for smaller windows under 36" wide. At under $10 for a pair, it's the lowest cost of entry in the NICETOWN lineup and the clear Best Overall on this page. Skip if your windows are standard 40-48" wide — you'll need two pairs per window, which shifts the value case toward the wider Grey panels at $16.80.

At $16.80, the NICETOWN Grey 52x63 sits in the middle of this under-$25 page but earns its badge with the wider 52" panel that covers standard 40-48" windows in a single panel. The $6.82 premium over the $9.98 Black 42x63 (Best Overall on this page) buys a 10-inch wider coverage footprint and a neutral grey color that works in bedrooms, living rooms, and offices where black panels might clash with existing décor or feel too heavy. For most standard window widths, one 52" Grey panel per window achieves proper coverage with enough fabric on each side to block edge light. The grey tone reflects less ambient light than white while staying neutral enough that the room doesn't feel cave-like during the day with curtains open. The grommet top with 6 rings per panel makes installation straightforward, and the fabric is machine washable — important for bedroom curtains that gather dust over time. Best for anyone wanting a finished, permanent blackout curtain for a standard-width window, with a versatile color that suits any bedroom. At $16.80 for a single panel, it's strong value for grommet-top construction with genuine blackout performance. Skip if your window is under 36" wide — the $9.98 black panels cover that size and save nearly $7 per panel.

The NICETOWN Triple-Weave panels at $23.95 are the premium pick on this under-$25 page — pushing right to the budget ceiling while delivering a third fabric layer the other two NICETOWN products here lack. That extra layer adds genuine thermal insulation: on a south or west-facing window in summer, the triple-weave construction measurably reduces heat transfer compared to a standard two-layer curtain, making it the practical choice for rooms where temperature control matters. The $7 premium over the Grey 52x63 ($16.80) and $14 over the Black 42x63 ($9.98) buys three things: the thermal layer, a heavier drape that hangs more naturally and reduces light gaps from curtain movement, and larger grommet rings that slide more smoothly on standard rods. At 52" wide, coverage footprint matches the Grey panels. Wrinkling out of the box is the main complaint — a light steam or a dryer run on low removes most creases within an hour. Best for bedrooms with south or west sun exposure, anyone in an extreme climate where curtain insulation affects heating and cooling costs, or anyone who wants the best long-term value among budget blackout options. At $23.95, it's the highest price on this page but the most feature-complete panel available under $25. Skip if budget is the primary driver — the $9.98 black panels deliver functional blackout at roughly one-third the cost.
