How to Measure

Before measuring ask yourself how am I going to hang this treatment.  Check the window opening for how you will install this treatment.  There may be molding and or paneling that intrudes into the window opening that you must work around.  Bath rooms and kitchens are notorious for tile in the window sill (in this event give us a call and we can walk you through it or come out and measure it for you - we do free estimates in the Dallas - Ft Worth metroplex).  Knowing how you will install the treatment is half the battle.  For example if you are ordering a 2" wood blind you will need 2" of room inside the window opening to mount the brackets to hold the blind.

Inside Mount

•  
• Always use a steel tape measure
•                               See Diagram 1
  window sill               1 1/2"                                                    1 1/2"

   

• 1 - Measure width first at the top of the window opening to the nearest 1/8 inch. - write it down
• 2 - Measure the width of the middle of the window opening - write it down
• 3 - Measure the width of the bottom of the widow opening - write it down -
• Don't panic if your measurements are not the same I have been in this business a long time and have not seen a perfectly square window opening yet.  Take the narrowest of the three measurements and that is your width.
• Now measure the Length starting at the left side of the window sill 4 (write it down) then the middle 5 (write it down) then the right side 6 and take the longest dimension for your height.  I usually add a 1/2" to insure the treatment sets on the window sill for privacy.
• W x H - it is important that you write the width first and height second (industry standards) when ordering

Outside Mount

For outside mount we do not mean on the exterior of your house, we mean outside the window opening.  Outside mount means we are going to make this treatment bigger than the window opening and mount it to the wall, into the studs beside the window opening. A fairly good rule of thumb is check your widow sill, it is usually 3 inches wider than the window opening. 

• Always use a steel tape measure
• Measure the width of the widow opening and add 3 inches (usually the width of your window sill - and this measurement will keep you mounting into the wall studs beside your window which will support the weight of your window treatment) - write it down
• Now measure the height from the window sill to the top of the opening and add 3 inches ( you will need this 3 inches for headrail room at installation.)
• W x H - it is important that you write the width first and height second (industry standards) when ordering
• Next on some treatments such as horizontal blinds 1" and 2" you will need a valance with returns to hide the ugly headrail at the top of the blind.  The returns bring the valance back to the wall and box in the headrail and make it much more attractive.
