Measure the Width of the Window/Door from the inside left to inside right. Add 6” on either side of the awning: so add an additional 12” to the inside awning width to obtain your finished awning width.

Measure the drop of the window from the mounting point to the centerline of the window. The projection is the same as the drop. This represents the measurement for surface installation. For Recess Installation, measure the inside width from left to right and the drop from the mounting point to the centerline of the window. The projection is the same as the drop.

Regular projections are the same measurement as the drop; 36” or 48”; however you have to take into consideration the direction of the sun and rain and the style of the awning. For a dome, the drop and projection must be the same as the width.

For a Canopy measure the projection the length of the landing or open area that requires to be covered.

Considerations

• The surface(s) should be level and flat – check the type of surface to which the awning will be attached to
• The type of window/door - opening in or out
• When measuring please consider all down pipes, air condition pipes, light fixtures, molding etc. that may affect your installation.
• The purpose of the awning
• The type of installation – recess or surface
