108 Inch Curtains Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

MIULEE is the best-performing 108 inch curtains brand in July 2026, moving 10,000 units across 1 ASIN for 36.8% of Top 10 volume. 100% Blackout Shield follows with 8,400 units (30.9%), ahead of H.VERSAILTEX on 2,000 units (7.4%).

With 8 brands splitting the Top 10 and 75.0% 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 $24.95 to $45.32, 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. Specifically, one ASIN forced its way in: B0B1ZP645F booked 2K units at $15.98. On the growth side, B07C9HL1G1 leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0D8KXZ9XW close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
