Measuring for Vertical Blinds

First, measure the width for the window. Then, add 3” to each side to make sure the head rail overlaps properly. Measure the desired length for the blinds. Make sure to add enough room for the head rail.

If ordering floor-length verticals, subtract ½” from the total length for proper operation. Recommended for mounting outside only.
 

Measuring for Roller Shades

Inside Mount-width
Measure the inside width of the frame at the top of the window. That size will be the inside mount size. Most factories will deduct 1/8” to allow for bracket placement.

Outside Mount-width
Measure the area you want the shade/fabric to cover. The shade should overlap the window 1 ½” on each side for best light control. That size should be the outside-mount size.

Note: Shades are available in standard lengths of 66”. Shade fabric does not go to the end of the roller. It is approximately 3/8” narrower on each side.
 

Measuring for Horizontal Blinds

Inside Mount-width
1” blinds need a window depth of at least 1 ½”, 2” blinds at a depth of at least 2 ½”. First, measure the width between bracket locations at the top, middle and bottom; use the narrowest measurement. Then measure length from top inside casing to sill. On made-measure products, a slight deduction will be made from the width ordered to allow for the placement of brackets; see individual products for details.

Outside Mount-width
Measure width of area to be covered, overlapping window by at least 1 ½” on each side. Measure to desired length from top of casing or at least 2” above the window if there is no casing.
 

Measuring for Draperies

Measure one drapery panel for length and width, then multiply the width by two to get the total width for the pair. Use this guide for replacement of draperies.

Measure the rod width, including the corners, and add 4” so the center can overlap when the draperies are closed. Ready-made draperies come in standard lengths of 54”, 63”, and 84”. To determine which length you need, simply measure the length from the top of the standard (white) traverse rod, or from the “eye” of the carrier on a decorative traverse rod. Use this guide for draperies when rods are already installed.
