How to Measure your Windows

General Overview:
Measuring your windows for Blinds, Shades or Interior Shutters is easy. Let's start with a few general rules that apply to all of the window treatments we sell. Remember, it's best to measure TWICE and order ONCE.

Rule 1. Always use a steel tape measure. Never try to measure your windows with a cloth tape, ruler or yardstick.

Rule 2. Measure down to the nearest eighth of an inch and do not round your measurements. Meaning don't measure 35 3/8" and call it 35" or 36".

Rule 3. When writing down your measurements be sure to indicate which measurement is the width and which is the height and ALWAYS note the width first, then the height. A common mistake customers make is transposing the numbers. Be sure not to get them backwards. Since these are custom made products it's generally very hard to have a size modified and can get costly to have them remade.
Measuring Example: your window is 36 3/8" wide by 60 1/4" high (tall). Think of it in these terms, Width is horizontal (horizon) left to right and height is vertical top to bottom. Your written measurements would look something like this... 36 3/8" x 60 1/4"

Rule 4. Inside Mount Only - Do NOT take any deductions . Our factory takes those allowances. You need to provide us with your EXACT WINDOW SIZE OPENING, do not use the size of an existing blind in that window. If you take your own deductions and then order as an inside mount you will get a double deduction when the factory also takes an allowance meaning your window treatment will not fit properly and you will have a larger gap between the treatment and the window opening.

Rule 5. Outside Mount Only - You need to provide the exact overall blind size needed (by adding the necessary coverage to the width and height of opening). Our factory makes most outside mount blinds the exact width and height you specify. NOTE: The height includes the OVERALL blind which includes the headrail, etc. One of the few exceptions are roller shades which the width is generally made as a tip-to-tip size. Meaning the fabric width is generally smaller than the width of the roller tube and bracket tabs. Since there is generally no deductions made on outside mount blinds, do not order your blinds as an outside mount if you are installing them inside a window opening as they will not fit. The blind cannot be the same exact size as the window it will be installed in as there must be room for hardware and clearance. Outside mount applications are usually used for windows that do not have an inside area, like a patio sliding glass door for example.

How to Measure for an Inside Mount Bay Window

1.	Where the Left section of the window meets the Center section: From the Left window Section, Measure out the distance of the depth for the blind type you are using. At this point make a small mark on your ceiling demonstrated by the red line on figure 1.
2.	Where the Center section of the window meets the Left section: From the Center window Section, Measure out the distance of the depth for the blind type you are using. At this point make a small mark on your ceiling demonstrated by the red line on figure 1.
3.	At the point where these two marks meet is the point where the blinds will butt up against each other. This point will be point A.
4.	Where the Right section of the window meets the Center section: From the Right window Section, Measure out the distance of the depth for the blind type you are using. At this point make a small mark on your ceiling demonstrated by the red line on figure 1.
5.	Where the Center section of the window meets the Right section: From the Center window Section, Measure out the distance of the depth for the blind type you are using. At this point make a small mark on your ceiling demonstrated by the red line on figure 1.
6.	At the point where these two marks meet is the point where the blinds will butt up against each other. This point will be point B.
7.	Now Measure the distance from point A to point B. Subtract 1/8" from this distance and that is the width of your Center blind (Shown in Light Blue in Figure 1).
8.	Measure from the left side of the left wall to point A. Subtract 1/8" from this distance and that is the width of your Left blind (Shown in Light Blue in Figure 1).
9.	Measure from the right side of the right wall to point B. Subtract 1/8" from this distance and that is the width of your Right blind (Shown in Light Blue in Figure 1).
10.	Order as Outside Mount (so no deductions are taken by the Factory) and in the 'Notes Section' of the order page request Inside Mount Brackets if mounting to the ceiling or top of window opening.

This is the width of Blind 1. • HEIGHT: Measure the height of the window opening. This is the height of Blind 1. Blind 2 on 2nd Window (The "Butt" Blind) • WIDTH: Measure exact width of the window opening. Find the Product you are measuring for from the chart above and deduct its depth from the width you just measured. This new value will be the Width of Blind 2. • HEIGHT: Measure the height of the window opening. This is the height of Blind 2. Outside Mount: see picture on right ----> Blind 1 on 1st Window (The "Pass" Blind) • WIDTH: Measure from the corner of wall to desired width of the blind. This is the width of Blind 1 • HEIGHT: Measure the height. Add a minimum overlap of 5" height, 3" to top and 2" to the bottom. This will allow the blind to cover the window and allow for maximum window coverage. This is the Height of Blind 1. (Note: If the window sill protrudes then add only for allowance above the window.) Blind 2 on 2nd Window (The "Butt" Blind) • WIDTH: Measure from the corner of wall to desired width. Find the Product you are measuring for from the chart above and deduct its depth from the width you just measured. This new value will be the Width of Blind 2 • HEIGHT: Measure the height. Add a minimum overlap of 5" height, 3" to top and 2" to the bottom. This will allow the blind to cover the window and allow for maximum window coverage. This is the Height of Blind 2.
