How to Measure Windows for Blinds in 5 Easy Steps

Blinds are beautiful and seamless additions to any room, creating a sleek aesthetic that is both functional and stylish. Measuring them properly can be a challenge, especially for those who have never done it before. If you want to revamp your space with elegant window coverings and wish to learn how to accurately record their height and width, we can help.

Step 1: Gather Your Supplies

Before you get started, having the right supplies on hand is a must. How you go about your preparation will make it easier to determine the dimensions of your windows. A measuring tape is the first item you will need – preferably made from metal. If they are made from plastic and fabric, they may leave room for some error because they could stretch as they are pulled from one side of the window to the other. Too much slack in the tape should also be avoided, which is why sturdy metal is best. Then, you will need a pencil as well as a notepad to record your dimensions. If your windows are on the taller side, you may want a ladder nearby and perhaps a second person to assist. Once you have your supplies, you are ready to start measuring.

Step 2: Measure Your Windows

Before measuring your windows, you must decide on inside-mounted blinds or outside-mounted blinds. Inside window mounts are attached to the inside of the trim or frame, which means the frame neatly encases the blinds. Outside mounts are installed above and over the frame, concealing it completely. The window frame is thus only revealed when the outside mounted blind is rolled up or opened. The type of mount you select determines how you will measure your windows.

– Inside Mounts

For inside mounts, you must check that there is enough space for a mount and its brackets that hold up the blinds. Larger coverings, like roller blinds, will require a larger gap in the window’s recess. Speak to your supplier about the specifications of their various types of blinds to get an idea of what will fit in the window recess. There should also be no obstructions in the way when opening or closing your blinds, like burglar bars or wall tiles and skirtings. A blind placed above a door should not be in the way of the door opening and closing freely.

– Outside Mounts

For outside mounts, you will need extra, unobstructed space of at least 100mm above the window. As with inside blinds, check that there are no obstacles inside or outside of the frame that can get in the way of the blinds opening and closing.

For both inside and outside mounts, you will require a length and width measurement as follows:

• Measuring width: When measuring width, start within the window recess, from left to right. Take three width-wise measurements – one at the top of the window, one in the middle, and one at the bottom of the window. It is acceptable if these numbers differ but be sure to jot down the narrowest measurement.
• Measuring length: When measuring the height, start inside of the frame, from the top to the bottom of the window. You will, again, need three measurements – down the left side of the window, down the middle, and down the right side. Record the tallest height of the three.

For outside mounts, once you have taken the above dimensions, you should add 100mm to both the width and height. For example, if the inside of your windows is (w)1 000mm x (h)1 000mm, it will become (w)1 100mm x (h)1 100mm for outside mounts. If you are still unsure about your measuring method or how accurate it is, it may help to call in a professional.

Step 3: Ensure Accuracy

Your measurements will determine the accuracy of the quote you get. For do-it-yourself installers, however, the dimensions must be exact as even being off by a centimetre can make the installation look odd or ill-fitting. How carefully and slowly you work will improve your accuracy, so try to measure your windows as meticulously as possible. Many industries use millimetres, so keeping to this unit of length is wisest. Be sure to measure to the last millimetre, which will also ensure a more accurate quote.

Figuring out how to take your measurements is only the first issue.
