What window sizes do you use to compare prices?

Two, so every seller and product compares on the same footing: a standard 35×48 window and a wide 72×48 window. Because custom blinds are priced by dimensions, fabric, lift, and options, a single "from $X" number is nearly meaningless — it attaches to whatever tiny size makes the headline look good. Quoting a real, fixed size (and dating the quote, since prices move) turns marketing back into a comparison you can act on. When you shop, plug your own window’s exact measurements into each seller’s configurator with the fabric and lift you actually want, and compare the resulting carts. Our benchmark quotes tell you who’s roughly cheaper for a comparable window; your configurator carts tell you the real number for yours.
