How to Measure :
Three basic measurements make up the most typical awning installation, Width, Drop and the Projection.
Points to keep in mind when measuring :
1) The mounting of the awning to a brick or wood base, either over a window or a door, must be on a flat surface.
2) The drop of the awning is typically less then one half (1/2) of the height of a window.
3) In cases where the awning is over a window that opens outward, then allowances can be made either by changing the mounting height or a double pitch awning. Also see the Soffit Mount measuring below.
4) If the awning is over a door, you must insure that when the door opens, it has clearance so it will not hit the awning. A double pitch designed awning can alleviate this situation.
5) If the awning is over a door, you must also insure that the lowest part of the awning is above the highest person you expect to walk under it, typically 6 foot 6 inches is lowest clearance allowed. Changing the Drop or the mounting height often allows for this situation.
Soffit Mount : A soffit mount may be desirable or required when there is a door or casement window that opens outward and clearances have to be made so the door or window does not hit the awning when it is opened. In this case it only requires one more measurement – the soffit. The measurement from the wall to the front of the fascia or mounting point of the awning and it actually equals what we call the cutback.
