How to Measure Vertical Blinds


 
Measure For Inside Mounting

Measuring For Inside Mount Vertical Blinds

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 2-1/2" is needed to install inside the window.

Find Height:

Measure from the inside top of the opening on the left, at the center, and on the right to the sill; to the closest 1/8" and note the smallest dimension.

Do not make any allowances: adjustments will automatically be made so the headrail will fit the opening properly and the vanes will clear the sill by 1/4" to 1/2".

Minimum Mounting Depth *
  Custom Order
Minimum Depth* 2-1/2"
Headrail Flush 3"
Flush Mount Vanes 3-3/4"
Flush Mount DesignLine Valance 5"
Flush Mount Traditional Valance 6-1/4"
Flush Mount Transitional Valance 5-1/2"
Flush Mount Visions™ Valance 4-3/4"

* Minimum depth is the depth required, in the window frame, for the blind to be mounted inside mount.


Measure For Outside Mounting

Measuring For Outside Mount Vertical Blinds

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.

Find Height:

Measure the height of the area to be covered round down to the nearest 1/8". Blind should extend at least 3" above and 3" below opening or window moulding.

For installations to the floor, deduct 1/2" from the shortest height for proper clearance.

Specifying outside mount measurement means the factory makes allowances for headrail deductions only.

Allow Some Overlap

For outside mount applications allow the blind to overlap 1-1/2" to 3" on the sides, top and bottom of the window.

You must add the overlap to your measurement; LEVOLOR does not add width or height for overlap on Outside Mounted blinds.

Notes

Blinds installed on windows near wall or baseboard heaters must clear the heaters by 12" above and 6" to the side.

Make sure there are no obstructions on either side of the window that may prevent you from ordering a wider blind.

Measure the area to the left and right of each window from the frame to the nearest obstruction (e.g. corner, fireplace, corner window, bookcases).

 

Measure For Outside Mounting

Measuring For Patio Doors

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.

Find Height:

Measure the height of the area to be covered at the left, center and right and round down to the nearest 1/8". Blind should extend at least 3" above opening or window moulding.

To ensure easy access through the door and allow adequate overlap, consider the stack width.

For installations to the floor, deduct 1/2" from the shortest height for proper clearance.

Specifying outside mount measurement means the factory makes allowances for headrail deductions only.

 

Vane Count and Stacking Chart


To Use This Chart:

These charts represent the amount of blind that is gathered to either side of the window when fully drawn. The measurements in these charts include the stack of the fabric.
