Halo Blinds ad: The 4 Best Blackout Blinds in 2026

Most “blackout” blinds are only blackout in the middle. The real problem is the light that sneaks in around the sides, top and bottom of your window. That is why even expensive blackout curtains can still leave your bedroom bright at 5 AM. Better Home Guide compared four popular blackout solutions, from affordable magnetic covers and blackout curtains to custom-made blackout frames. The differences were bigger than expected. One option stood out because it does not just use blackout fabric. It uses a made-to-measure frame that seals the edges of the window, installs without drilling and slides open whenever you want daylight again. Before spending money on new blackout blinds, see which option was ranked number one, and which products may still leave you dealing with light gaps.
