The first step to enjoying these benefits is getting the measurements correct.
📌 Key Takeaways
How to measure for vertical window blinds starts with deciding between an inside mount and an outside mount.
Measure the width and height at several points because window openings may not be perfectly square.
Use a steel measuring tape for more accurate results.
Follow the manufacturer’s instructions when choosing which measurements to submit.
Do not make your own deductions unless the manufacturer specifically requests them.
Check for handles, trim, cranks, and other obstructions before ordering.
Here’s the good part: You don’t need any special skills to get it right. With some simple tools and this guide, you can ensure a perfect fit without much hassle.
Why Getting the Measurements Right is Important to Install Custom Vertical Blinds
Accurate measurements are essential when ordering made-to-fit window treatments. Learning how to measure for vertical window blinds correctly can help prevent issues with fit, appearance, and operation.
Blinds that don’t match the window size can create trouble. They might not open or shut right if they’re too wide or narrow. If they’re too short, light gets through. If they’re too long, they end up dragging on the floor.
Measuring helps ensure your custom vertical blinds for windows fit. They will look better and work as they should. This is important if your windows are large or have unusual shapes. Starting with the right measurements from day one saves effort and frustration down the line.
What Are Custom Vertical Blinds for Windows?
Custom vertical blinds are made to match your window’s size and preferred style. Unlike store-bought blinds, these are created to fit right. Plus, you can choose:
- Different materials such as fabric, vinyl, or PVC
- A Variety of colors and designs
- Options for controlling them, like wands or cords
- Extra features, including blackout linings or textured looks
These work well for extra-tall or wide windows, patio doors, or spaces where total coverage matters. You can combine them with softer window treatments like fabric blinds for windows to add layers and bring in more style.
Step 1: Choose How You’ll Mount Your Blinds
Decide if you’ll install the blinds inside the window frame or outside it before figuring out how to measure for vertical window blinds. Your mounting style determines which measurements you need to take.
Mounting Inside
- Mounts inside the window frame
- Creates a sleek built-in appearance
- Needs at least 2.5 inches of frame depth to fit
Outside Mount
- Mounts above or around the window frame
- Works better with shallow or uneven frames
- Covers more space and blocks out extra light
Once you decide, it’s time to measure!
Step 2: Get What You Need to Measure
You just need a few simple things:
- A steel measuring tape (skip the soft ones)
- A pencil and some paper, or use your phone instead
- A step stool or ladder if the windows are high
Make all measurements in inches and round to the closest 1/8 inch to get the most accurate results.
Step 3: How to Measure To Install Inside Mount Vertical Blinds for Windows
To measure an inside mount, focus on the area inside the window frame.
Width:
- Take measurements at the top, middle, and bottom of the window opening.
- Record all three numbers.
- Base your order on the smallest number you record.
Height:
- Measure from the top of the window frame down to the window sill at the left, middle, and right.
- Use the largest number to ensure the blinds fully cover the height of the window.
Some manufacturers may ask you to submit the longest height, while others provide different instructions depending on the product. Follow their measuring guide rather than making deductions yourself.
Understanding how to measure for vertical window blinds for an inside mount can help ensure the headrail and vanes fit properly within the opening.
Tip: Do not automatically subtract from your measurements. Many manufacturers make the necessary production deductions for inside-mount blinds.
Step 4: Measure for Outside-Mount Vertical Blinds
When determining how to measure for vertical window blinds for an outside mount, focus on the total area you want the blinds to cover.
Width:
- Measure the window’s width
- Add 3 to 4 inches to each side to improve light blocking and coverage
Height:
- Start from where you want the headrail placed, a little higher than the window, and measure down to where the blinds will end, like the sill or the floor
This setup offers more freedom and works well in areas where you need more privacy or less light.
Step 5: Check Your Measurements One More Time
Double-checking is an important part of how to measure for vertical window blinds because even small mistakes can affect the final fit.
Take a moment before ordering:
- Check all your measurements again.
- Confirm you listed the width and height.
- Verify whether you’re going with an inside or outside mount.
- Note down which room or window each measurement belongs to.
Doing this avoids mistakes later and keeps your order on point.
Watch Out for These Measuring Mistakes
Knowing how to measure for vertical window blinds can also help you avoid some of the most common errors.
- Measuring just once: Always take measurements at three different spots to check the width and height.
- Making guesses or rounding up: Round measurements to the nearest 1/8 inch, but don’t round upward.
- Using improper tools: Use a metal measuring tape; it works best.
- Overlooking obstructions: Remember to include handles, window cranks, or trim when measuring.
Simple Tips to Achieve a Great Fit and Appearance
Once you know how to measure for vertical window blinds, a few additional considerations can help you get a better overall result.
- Start with the purpose: Pick blinds that match how you use the space. Think about things like privacy or lighting.

- Be thorough, not quick: Measure and double-check to avoid mistakes. Taking it slow pays off.
