How to Measure for Vertical Blinds

 

For Outside Mount Vertical Blinds

1. To find width: Measure the width of the area to be covered at the place where the headrail will be installed to the nearest 1/8″. Blind should overlap opening at least 4″ on each side to ensure privacy. To maintain the maximum view, allow adequate overlap and consider the stack width.
2. To find height: Measure the height of the area to be covered and round down to the nearest 1/8″. Blind should extend at least 3″ above and 3″ below opening or window frame. For installations to the floor, make adequate allowance for carpeting. Specifying Outside Mount measurement means the factory makes no allowances.

Notes

  • Smallest unit of measure is 1/8″.
  • Blinds installed on windows near wall or baseboard heaters must clear the heaters by 12″ above and 6″ to the side.

For Inside Mount Vertical Blinds

1. To find width: Measure the opening across the top, where the headrail is to be installed, from inside of window frame on left to inside of window frame on right. Round the measurement down to the nearest 1/8″. A minimum depth of 2″ is needed to install inside the window.

2. To find height: 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 headrail will fit the opening properly and the vanes will clear the sill by 1/4″ to 1/2″.

Patio Doors

1. To find width: Measure the width of the area to be covered at the place where the headrail will be installed to the nearest 1/8″. Blind should overlap opening at least 4″ on each side to ensure privacy. To ensure easy access through the door and allow adequate overlap, consider the stack width.

2. To find height: Measure the height of the area to be covered and round down to the nearest 1/8″. Blind should extend at least 3″ above opening or window frame. For installations to the floor, deduct 1/2″ for proper clearance. Specifying Outside Mount measurement means the factory makes no allowances.
