The way to Measure for Earning Window Valances and Treatments

Effective window valances and therapies depend on many things: the first being true measurements. These influence the design and building of the bits, and knowing what to measure and how to quantify is vital for this procedure. Just like measuring your body before making a dress, a window treatment starts with measuring the window. The plan procedure that follows determines the true size of the valance pieces or window treatment length and length. After taking the precise dimensions, a homeowner is going to have a solid foundation for designing or choosing the window treatments, ensuring the successful outcome of the undertaking.

The Basics

Window width is the distance from left to right, and length is the measurement from the top to the bottom. It’s expressed as “width by duration” and composed ” width x length” This standardization of measurement additionally suggests the form of the window and also indicates its alignment on the wall. As an example, a window composed as “45×20” suggests the window is 45 inches from side to side and 20 inches from top bottom, and it is a rectangular window put horizontally on the wall. Use a metal tape measure and record the dimensions to 1/8 inch.

Inside Mount

For therapies and valances mounted within the window frame, measure from side to side within the window frame. To guarantee the window treatment does not stretch out to the room, measure the thickness of the window therapy headrail or mount, and ascertain in which the hardware must be mounted to accommodate this thickness. Assess the width of the window at this place throughout the top of the window, the middle and bottom. Use the smallest of the three dimensions. Assess the length at the left, middle and right sides of the window within the frame, and then use the longest of these measurements as the span.

Outside Mount

Assess the width of the wall region you wish to cover, then add the return measurement if applicable to your selected design. The return is the measurement of the distance in the front of the rod to the wall, and window treatments normally cover this space. If blind hardware is present, ensure the window therapy or valance is wide enough, and has a return deep enough, to clean the blind by at least 2 inches over the front and at the sides. As an example, for an outside-mounted blind with a width of 60 inches, and a return of 4 inches, the window treatment must be 64 inches wide with a return of 6 inches.


Install the window treatment hardware to the wall or window in the selected place, and take the dimensions for the valance or therapy from the hardware. This procedure emphasizes any probable difficulties with hardware which might not be evident from measuring alone, and which may affect the dimensions of the window treatment — for example, the available space for mounting a mount above a window, or the thickness of the return not allowing a door to open fully.


The total quantity of fabric added to the following dimensions for seam allowances, hems and fullness is dependent on the style and type of window treatment. As an example, a gathered valance may need two or three times the rod width for decent fullness, and is affected by the selected fabric weight and opacity. A grommet curtain or valance typically requires one-and-a-half times fullness but can be more. Hem allowances also are added depending on the selected style and if lining is used. Typically, window treatment valances have a lining thickness of one to three inches, but a curtain lining may be as small as a 1/4-inch rolled hem to a dual 4- or 6-inch hem.The alternative is random and part of the design procedure. A self-lined, curved hem valance, as an example, could have a 1/4-inch seam allowance; an unlined valance of the exact same style might need a facing, or could have a rolled hem. Valance span is decided by the size of the window and also the fashion of the valance. Typically, a valance is 1/5 the length of the indicated window span, but this really is a personal option. Hanging a valance higher than at the top of the window frame makes the window appear more easy; it is this perceived window span which has an impact on the length of the valance. After taking the window dimensions, the design procedure will determine the size of the valance.
