Looking to install no-drill blinds in your home? Whether you call them no‑drill window blinds or no‑screw blinds, accurate measurements are key to getting a flawless fit. This guide walks you through how to measure for no‑drill blinds, with easy-to-follow steps and expert tips. You’ll learn how to install no‑drill window blinds with confidence, even if you’re working with tight spaces and limited tools.

Why Accuracy Matters
Proper measurement ensures that your blinds fit cleanly, function smoothly, and look professional.
For inside-mounted window coverings, a variance as small as 1/8″ can lead to misalignment or poor tension, causing your blinds to not fit. For outside mounted, stick-on blinds for windows, getting the right width is important so that your windows are fully covered.
Quick Tips for Measuring No‑Drill Blinds
If you’re wondering, “can I measure for blinds without tools,” we’d advise that measuring with tools is how you get a best fit no‑drill blinds measurement. Here’s a few general measuring tips for no‑screw blinds:
- Measure twice to confirm accuracy.
- Use a steel tape, not cloth, for straight readings. It’s the best and easiest way to size no-drill shades.
- If your frame depth isn’t enough, consider a different inside-mounted solution. You can find the depth required under each product’s Specifications section.
- Avoid using Click2Fit and Twist2Fit no-drill blinds on PVC frames.
With proper measurement, you’ll have easy install blinds that look as good as they work—quickly and without drilling.

No-Drill Blinds Measuring Guide
Click2Fit No-Drill Blinds
The Click2Fit headrail is only available for an inside mount, and it requires 1 1/2″ or 2 1/2″ of depth to install based on the minimum depth or flush depth. It is not recommended for use with PVC window frames.
Measuring the Width
- To determine the width, measure from left to right on the top, middle, and the bottom.
- Compare the three measurements, and if the variance between them exceeds 1/4″, the Click2Fit headrail may not fit properly.
- Input the exact measurement of the top of your window frame into the width field.
- This is the width you will use when ordering.
- No deductions are needed on your end! The factory will deduct approximately 1/4″ off of the headrail, regardless of lift style.
Measuring the Height
- To determine the height, measure from top to bottom on the top left, then the center of the window, and then the top right to the bottom of the window sill. Use the largest height out of those numbers.
- If you get a 1/16” or 1/32” increment, round up to the nearest 1/8”.
- This is the height you will use when ordering.
Twist2Fit No-Drill Blinds
Similarly, the Twist2Fit headrail is only available for as an inside mount, and it requires 2 1/2″ of depth to install. It also is not recommended for use with PVC window frames.
Measuring the Width
- Measure the exact width of the top of your window frame and input those dimensions into the width field.
- This will be the width you order.
Measuring the Height
- The height measurement is taken from the window frame in three places (top left, center, and top right down to the window sill).
- Record the largest height out of the 3 measurements up to the nearest 1/8”.
- If you are getting a 1/16” or 1/32” increment, round up to the nearest 1/8”.
- This will be the height you order.
Please note: there will be fabric deductions of about 1″ on the control side and 3/4″ on the tension dial side, creating light gaps. You do not need to take deductions on your own!
Stick2Fit No-Drill Blinds
The Stick2Fit headrail works as an outside mount only. Its adhesive strip works on aluminum, wood, PVC, vinyl and painted walls. You need at least 2 ½” of a flat surface for installation.
Measuring the Width
- Begin by measuring the exact width of the window opening in three main places (top, middle, and bottom).
- Record the largest width out of the 3 measurements.
- If you get a 1/16″ or 1/32″ increment, round up to the nearest 1/8″
- You’ll use that measurement and add the recommended minimum of 4 inches to ensure the window is properly covered. For more light coverage and privacy, add even more to the measurement.
- Use this final number for the width.
Measuring the Height
- Measure the height of the window in three places, including the top left, the middle, and the top right, all ending at the bottom of the sill.
- You’ll use the largest of the three measurements and add the recommended minimum of 4 inches to ensure the window is properly covered.
- Use this final number as the height.
How to Install No‑Drill Window Blinds
Click2Fit No-Drill Blinds
These blinds utilize tension levers, a non-invasive mounting option, to secure them in place. The tension bar fits tightly within the window frame, creating pressure that holds the blinds in place.
Twist2Fit No-Drill Blinds
Twist2Fit blinds feature a tensioned twist mechanism that allows for instant mounting and easy removal. Simply set the headrail into the window frame and turn the tightening wheel to lock it in place.
Stick2Fit No-Drill Blinds

- Use the included alcohol wipe for a final surface sanitation.
- Peel back the adhesive on the headrail.
