How to Install Blinds or Shades

No matter which kinds of blinds you choose, the procedure for how to hang blinds starts with measuring the windows. While you can measure both inside-frame dimensions and outside-frame dimensions, it’s best to decide beforehand which mounting style you’ll use.

You will need to measure at least two dimensions: the width and the height. Finding the depth may also be important for some inside frame blinds, so take that measurement just in case. For each dimension, you will take three measurements in different locations. Measuring this way will be more accurate because buildings settle over time.

Inside frame mounting:

• Measure the width, from inside edge to inside edge, at the top, middle and bottom of the frame. Record the narrowest measurement, and consider rounding down to the nearest 1/8 inch. The blinds won't fit if they're wider than the area.
• Measure the length, from inside edge to inside edge, at the left, middle and right of the frame. Record the longest measurement.
• Measure the depth at the top, middle and bottom of the frame. Record the average measurement.

Outside frame mounting:

• Measure the width from outside trim to outside trim at the top, middle and bottom of the frame for precision. Record the longest measurement. You may want to add 3 inches for extra coverage on the sides.
• Measure the length from outside trim to outside trim at the left, middle and right of the frame. Record the longest measurement. Again, you may want to add 3 inches for extra coverage on the bottom. Blinds can always be raised if they’re too long.

Tips for measuring:

• Use a metal tape measure, not cloth.
• Consider using a laser level to be sure your measurements across the frame are in-line with the starting point.
• Round to the nearest 1/8 inch.
• Get someone to assist. Measuring will much easier when you have someone to help, especially if you're on a ladder.

What makes blinds suitable for your specific windows? The right type of blinds depends on a few key factors.

• Depth of the window – If the window frame is not very deep, you may prefer outside mounted blinds to cover the area more easily.
• Desired light control – Inside-mounted blinds don’t offer as much light-control. Light is also a result of the blinds’ composition.
• Layered window treatments – If you’re using curtains, drapes or other window treatments in addition to blinds, inside-mounted blinds are the better option.
• Window size and purpose – Some windows will be opened frequently and need easy-to-operate blinds. Others may be on windows too large for horizontal blinds. The type of blinds you choose should be compatible with how you’re going to use them and how much area you need to cover.
• Temperature considerations – Blinds are made from different materials and in different colors, both of which affect their ability to insulate. Know what kind of insulation you need your blinds to address.
• Humidity levels – Some materials do better with high-humidity locations. Consider the typical weather conditions and whether the blinds will be in a more humid room in your home.

The process of installing window blinds doesn’t require any special window preparation, but it may be a good idea to do a few chores beforehand anyway. This will make the job easier and potentially safer for any workers.

If you already have blinds on your windows, the first step in how to change blinds is to carefully remove the old ones. Use this step to also look for damage, dust and debris so you know what to pay close attention to with your new ones.

Next, clean the area around the workspace. Use a window cleaner or all-purpose cleaner to wash the window, the window sill and the trim around it. If you have plants, furniture or other items close to the area, remove them to reduce clutter and potential hazards.

Learning how to hang blinds using an outside mount installation provides better light control. This can enhance the look of windows by making them appear larger.

Inside mount installation:

• Before installing blinds, use a metal tape measure to determine where to place the headrail brackets. Mark this location.
• Measure and mark the recommended distance away from the window. This will make sure the vanes rotate freely.
• Use a power drill to drill pilot holes where your marks meet.
• Drive the screws through each bracket with the valance clips attached. Be sure your brackets are even before screwing them in completely. Adjust them as needed.
• Attach the headrail by positioning it in front of the brackets. Rotate it down until it snaps into place.
• Use the wand to evenly space the plastic stems along the headrail. Rotate the stems until the inside parts are visible.
• Attach each vane by sliding them up into each stem. They should snap into place.
• When the vanes are attached, install the valance onto the valance clips.

Outside mount installation:

• Choose the point at the bottom of your window where you want your blinds to hang. Measure up to the top of the window the length of the blind you ordered. Mark this location.
• Place the headrail on this marking. Make two more marks 4 inches in from each end of the headrail.
• Align the top of the first bracket with the first 4-inch mark and fasten it to the wall with the supplied screws. Repeat this process on the other bracket.
• Hook the front of the headrail into the brackets. Rotate it back until it snaps into place.
• Use the wand to evenly space the plastic stems along the headrail. Rotate the stems until the inside parts are visible.
• Attach each vane by sliding them up into each stem. They should snap into place.
• When the vanes are attached, install the valance onto the valance clips.
