Blackout Curtains for Small Window 40 in Long - Full Room Darkening

In this review the BGment Short Blackout Curtains are evaluated for anyone needing a compact, effective window treatment for small windows. The review finds the pair delivers the single biggest benefit: reliable, full room darkening with thermal and sound-reducing backing in a neat 40 in length that fits most low or basement windows. For renters, bedrooms, or media rooms where light control and privacy matter, these curtains provide a clear and practical upgrade without complicated installation or extra hardware.

Key Features

• Complete blackout: The curtains use a black backing to achieve near 100% light blocking, which creates darker sleeping and viewing environments.
• Size and fit: Each panel is 42 in wide and 40 in long, so the pair covers about 84 in of width and fits short windows or spaces under drapery rods with a 3 in rod pocket.
• Thermal insulation: Lined construction helps resist outdoor heat in summer and retain indoor temperature in winter, making the room more comfortable and helping save energy.
• Noise reduction: The two-layer full blackout design reduces outside noise better than single-layer panels, helpful for sleep and media use.
• Easy care: Machine washable fabric simplifies maintenance; just avoid bleach to keep the blackout backing intact.

Who It's For

These curtains are best for renters, apartment dwellers, and homeowners with small or low windows who want a straightforward, no-fuss solution for complete darkening and extra privacy. They work well in bedrooms, nurseries, media rooms, or kitchens where light control and a heavier look are desirable.

Those who need floor-length panels or specially sized drapery hardware should look elsewhere, since these panels are specifically 40 in long and rely on a 3 in rod pocket rather than grommets or rings for hanging. Also, customers wanting patterned or sheer styles will need a different option.

Pros & Cons

Pros

• Effectively blocks light for improved sleep and privacy.
• Thermal lining offers measurable heat retention and potential energy savings.

Cons

• Fixed 40 in length and rod pocket style limit hanging options for some window setups.
