The size above is the size of the blind. Before placing order, please measure your window opening. To ensure that the blind fits inside the window frame, the width of the opening must be 1/2 inch larger than the width of the blind that you purchase. For the blind to be flush with the window frame, the opening must be at least 3 inch deep. Our blinds are crafted with high quality components including high profile steel head rails, quality PVC foam slats, wood tassels, and solid trapezoid bottom rails. Our blinds resist heat and humidity, and are great for all areas including the kitchen, laundry room, and bathroom. Mounting hardware; clips, screws, and brackets, are included in the box. An inside-mount valance without returns is also included.
