Measure For Your Window Blinds

Mini Blind Inside Mount Measuring Instructions	Width: Measure exact distance to the nearest 1/8" between inside surfaces of window frame at the top, middle and bottom, and use the narrowest width. Do not make any width deductions. Length: Measure exact distance to the nearest 1/8" from inside surface at top of window to sill at the left, middle and right and use the longest length. If you prefer blind not to touch sill, deduct 1/4". If there is no sill, measure length to point where blind is to reach.
Mini Blind Outside Mount Measuring Instructions	Width: Measure exact distance to the nearest 1/8" between the outermost points where the blind is to be placed. For optimum light control, this measurement should extend 3/4" beyond the window opening on each side (or 1-1/2" for the entire width). Length: Measure exact distance to the nearest 1/8" from where top of blind or shade will be located to top of sill. If there is no sill or if blind is to overlap window frame, measure to point blind is to reach.
Vertical Blind Inside Mount Measuring Instructions	Width: Measure the opening across the top where the head-rail is to be installed from inside of jamb on left to inside of jamb on right. Round the measurement down to the nearest 1/8". Length: Measure from the inside top of the opening on the left, at the center, and on the right to the sill; round the measurement down to the nearest 1/8" and note the smallest dimension. Do not make any allowances: the factory will make all adjustments so the head-rail will fit the opening properly and the vanes will clear the sill by 1/4" to 1/2".
Vertical Blind Outside Mount Measuring Instructions	Width: Measure the width of the area to be covered at the place where the head-rail will be installed to the nearest 1/8". Blind should overlap opening at least 2-3" on each side to ensure privacy. Length: Measure the length of the area to be covered and round down to the nearest 1/8". Blind should extend at least 2-3" above and 2-3" below opening or window molding. For ceiling-to-floor installations, make adequate allowance for carpeting. Specifying OB measurement means the factory makes no deduction allowances.
