How to Measure


 
 
Measure For Inside Mounting

Measuring For Inside Mount Wood Blinds

For a beautiful framed look

Find Width:

Measure to the nearest 1⁄8 in. between inside surfaces of window frame; at the top, middle, and bottom. Record the narrowest width of the three.

Find Height:

Measure to the nearest 1⁄8 in. from inside surface at top of window to top of sill; at the left, middle, and right. Record the tallest height of the three.

Find Depth:

Measure exact depth of window casing making note of any obstacles i.e. handles, tracks or cranks that could interfere with the blind function. Use the shortest depth.

 
 
Measure For Outside Mounting

Measuring For Outside Mount Wood Blinds

For increased light control and privacy

Find Width:

Measure to the nearest 1⁄8 in. between outermost points where blind is to be placed. Measurement should overlap each side of window frame by at least 1 1⁄2 in.

Find Height:

Measure to the nearest 1⁄8 in. from where top of blind will be located to top of sill, or measure to point of blind reach if no sill.

 

Window and Measuring


Window Components

Collectively, the sill and jambs are called the "window casement" or "frame".

Inside Mount

Blind fits within window opening.

Great for windows with beautiful trim.

Outside Mount

Blind mounts outside window opening.

Increased light control and privacy.

 
 

Multiple Blinds on One Headrail

Provides the clean appearance of a single blind with the ability to operate each blind independently.

Can be mounted inside or outside.

Can be 2-on-1 or 3-on-1, depending on width of window. 2-on-1 is shown in image above.

 

How to Measure Two Blinds on One Headrail (2-on-1 Headrail)


INSIDE MOUNT (IM) INSTALLATION

MEASURE WIDTH

Overall Blind Width - Measure to the nearest 1⁄8 in. between inside surfaces of window frame; at the top, middle, and bottom.

Left Blind Width - Measure the width that you want the left blind to cover. Order this blind first when placing your order

Right Blind Width - Measure the width that you want the right blind to cover.

MEASURE HEIGHT

Overall Blind Height - Measure to the nearest 1⁄8 in. from inside surface at top of window to top of sill; at the left, middle and right. Record the tallest height of the three.

MEASURE DEPTH

Overall Blind Depth - Measure exact depth of window casing making note of any obstacles i.e. handles, tracks or cranks that could interfere with the blind function. Use the shortest depth

Measure For Multiple Blinds per Headrail
 

OUTSIDE MOUNT (OM) INSTALLATION

MEASURE WIDTH

Overall Blind Width - Measure to the nearest 1⁄8 in. between outermost points where blind is to be placed. Add an additional 3 in. to 6 in. to total width for maximum privacy.

Left Blind Width - Measure the width that you want the left blind to cover. Order this blind first when placing your order.

Right Blind Width - Measure the width that you want the right blind to cover.

MEASURE HEIGHT

Overall Blind Height - Measure to the nearest 1⁄8 in. from where top of blind will be located to top of sill, or measure to point of blind reach if no sill.

 

How to Measure Three Blinds on One Headrail (3-on-1 Headrail)


INSIDE MOUNT (IM) INSTALLATION

For a beautiful framed look

  • Available up to a total maximum width of 144"
  • Each blind operated independently
  • There will be inner spacing between slats of individual blinds to operate independently

  • Left Blind tilt controls are on the left side and Right Blind tilt controls are on the right side for 2-on-1 cordless blinds
  • 3-on-1 Middle Blind will always be Cordless
  • Always use a metal tape measure as cloth may stretch
  • Take all measurements to the nearest 1⁄8 in. DO NOT take any deductions
  • The factory will make any necessary adjustments to help ensure your blind operates smoothly
  • Horizontal slat alignment is not guaranteed

Valance Return Dimensions - Inside Mount

  • For inside mount installations where headrail protrudes from window casing.
  • Returns may be ordered in sizes ranging from 1⁄2" to 6".
  • Measure to the nearest 1⁄8" using a metal tape measure.
  • If the valance is the same width as the blind, measure from the window trim to the end of the headrail.
  • If the valance is wider than the blind and extends over the window trim, measure from the wall to the end of the headrail.

(If you are unable to measure for returns LEVOLOR recommends a return size of 1⁄2" which will work for most situations.)
