How to Measure Windows for No Drill Blinds: Tips and Tricks

Choosing the right window treatments can transform the look and feel of your home, and when it comes to no drill blinds, proper measurement is crucial for a perfect fit. Whether you're renting, looking for temporary solutions, or simply prefer easy installation options, measuring your windows accurately ensures that your blinds not only look great but also function effectively. Here’s a comprehensive guide on how to measure your windows for no drill blinds, along with tips and tricks to get it right the first time.

Why Accurate Measurement Matters

Before diving into the measurement process, it’s essential to understand why accuracy is key when installing blinds, especially those that rely on non-permanent mounting solutions like adhesive or tension rods. Proper measurements ensure that your blinds fit snugly within the window frame or on the glass surface, providing optimal light control, privacy, and aesthetic appeal. A well-fitted blind not only enhances the overall look of your space but also prevents light leakage and ensures ease of operation.

Tools You'll Need

To begin, gather the following tools to facilitate accurate measurements:

  • Measuring Tape: A retractable measuring tape is essential for precise measurements of width and height.
  • Notebook and Pen: Keep track of measurements and any notes about the windows, such as obstructions or uneven surfaces.
  • Level: Use a level to ensure that blinds are installed straight and level, especially for adhesive or magnetic mount options.
  • Step Stool: If your windows are high or difficult to reach, a step stool will come in handy for accurate measurements.

Step-by-Step Measurement Guide

1. Measure Window Width

Start by measuring the width of the window frame or the width of the glass if you're opting for inside mount blinds. Take three measurements: at the top, middle, and bottom of the window. Note down the smallest measurement to ensure that your blinds will fit properly without rubbing against the sides.

2. Measure Window Height

Next, measure the height of the window from the top of the frame to the sill or to the desired length if you prefer longer blinds. Again, take three measurements: on the left, center, and right sides of the window. Record the shortest measurement to ensure that your blinds won’t drag on the floor or window sill.

3. Consider Mounting Options

Depending on the type of no drill blinds you choose, determine whether you will mount them inside the window frame (inside mount) or on the wall or window frame (outside mount). Inside mount blinds fit within the window recess for a streamlined look, while outside mount blinds cover the entire window and may require additional width and height measurements.

4. Account for Obstructions

Take note of any obstructions such as window handles, locks, or tiles that may affect the installation or operation of your blinds. Measure the distance from these obstructions to ensure that your blinds can be installed without interference.

Tips for Success

  • Double-Check Measurements: Verify all measurements before purchasing your blinds to avoid ordering the wrong size.
  • Consult Installation Instructions: Review the manufacturer's guidelines for specific instructions on measuring and installing your chosen blinds.
  • Consider Light Control: For optimal light control, choose blinds that extend slightly beyond the window frame, especially for outside mount installations.
  • Seek Professional Assistance if Needed: If you're unsure about measuring or installing blinds, consider consulting a professional for guidance.


Measuring your windows accurately is the first step towards achieving the perfect fit for your no drill blinds. By following these tips and tricks, you can ensure that your window treatments not only enhance the aesthetics of your home but also provide functional benefits such as privacy and light control. Whether you opt for adhesive roller blinds, tension rod cellular shades, or magnetic mount roman shades, proper measurement sets the foundation for a seamless and stylish installation. Take the time to measure carefully, and enjoy the transformation of your living space with hassle-free window treatments.
