How to Measure your Windows

Installation Tips for Roller Shades

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.
Measuring Example: your window is 36 3/8″ wide by 60 1/4″ high (tall). Your written measurements would look something like this… 36 3/8″ x 60 1/4″

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 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.

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.

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.

Choose Inside or Outside Mount Installation:

For an inside mount, the window opening must have enough unobstructed depth to allow mounting. Be sure to look for obstructions like window locks, window cranks, etc.

Tips: For a flush inside mount (the blind completely recessed so that no part of the blind projects out of the opening) check that you have enough depth and make sure that if a valance is included that we make it slightly smaller than the window opening width since they are normally made an inch or two wider.

Tips: We usually recommend an inside mount whenever possible because it provides a cleaner look. However, an outside mount can make a window appear larger or hide an unattractive window. When you specify inside mount, we will make a size deduction to allow for operating clearance. With most products we will deduct up to 1/4″ from each side. Roller shades also have a rather large fabric and roller tube deduction (see product specs tab on product pages).

For vertical blinds there is also a height deduction of 1/4″. The deductions are made so that the blind will not rub or scratch your window frame. If you specify an outside mount, we will not take any size deductions. Your blind will be made at the exact size you specify. So you must ADD to the opening measurement to allow for overlap and mounting brackets. When measuring, don’t be surprised if your windows are not square. It’s not uncommon and probably won’t be noticeable.
