Black Out Curtains 72 Inch Long Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

NICETOWN is the best-performing black out curtains 72 inch long brand in July 2026, moving 28,000 units across 3 ASINs for 37.8% of Top 10 volume. MIULEE follows with 14,000 units (18.9%), ahead of ChrisDowa on 10,000 units (13.5%).

With 7 brands splitting the Top 10 and 70.3% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $11.69 to $20.47, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. On the growth side, B07X3H3YKG leads positive momentum with ▲ 500.0% MoM growth on 600 units, with B07D7XTS27 close behind at ▲ 100.0% MoM on 200 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
