People buy blinds but don’t know how to measure the right window size for a perfect fit. Some homeowners might find it unpleasant to measure for perfect fit blinds. A blind with an accurate fitting gives the window a uniform look and reliable functioning. Whether the blinds are too big or too small, they either hang low or don’t even fit the frame properly. The root cause of this is inaccurate measurement. Lush Loom is here to resolve these issues with its professional guide for measuring the perfect fit blinds.
Importance Of Knowing Your Window Type Before Taking Measurements
There are certain types of windows that perfect fit blinds just don’t work on. Those types are as follows.
- PVC windows With Internal Beading.
- Aluminum Windows With Detachable Beading
- Composite Windows With Destandardized Beading
- Tilt And Turn Windows
There are specific reasons that these window types matter.
- Depth Varies: If some windows have shallow depth, they might need slimmer and thinner brackets.
- Shape Matters: The shape of the window mostly decides how the blinds will sit on the windows.
- Material Matters: Frames that are made of aluminum or other lightweight metals can have tighter tolerances.
Collect Measuring Tools & Materials
Personal safety is extremely important while working with sharp tools. Here are the two individual lists of the safety gear and the tools which you are going to need for accurate plus safe measurements for blinds.
- Metal Measuring Tape (digital tape if available)
- Notepad & Pen
- Ruler or Straight Edge
- Brush or Cloth to clean dust from the beading
Safety Gear
- Anti-slip gloves (windows can be high)
- Safety glasses if near construction dust
- Step stool or ladder for tall windows
- Soft knee pads for floor-to-ceiling windows
Avoid flexi-tailor tapes—they sag and ruin accuracy.
A 5-Step Measuring For Perfect Fit Blinds | Easy & Effective
Here is a step-by-step guide to measure for perfect fit blinds in Dubai. First of all, you need to decide which type of blind fitting you’re going to set: recess or exact.
Measuring The Window Width From Three Spots
Importance: Glass windows aren’t always cut straight – not even in a city like Dubai. There is a possibility that the width and height may differ — sometimes even by a few millimeters.
Measuring: That is the reason that the glass and window shall be measured from at least three points to minimize the error rate.
Using a measuring tape to measure the width from the highest point of the window, then from the middle, and lastly, from the bottom-most point. Compare the three measurements and always choose the smallest measurement.
The reason for choosing the smallest window is significant, especially in the case of fitted blinds. These blinds must sit within the smallest measurement for a perfect fit. Otherwise, you will face problems trying to fit the brackets inside the frame.
Measuring The Glass Height From Three Spots
This step uses the same logic applied to the different axes. Now, measure the height of the window glass (only glass). Measure from three points. The first measurement would be from the extreme left, then from the center, and lastly from the extreme right.
The reason for this is that sometimes, some of the windows in Dubai have arch windows. Use the smallest measurement for a tailored fit.

Precisely Measuring The Internal Beading Depth
Importance: This is the most important reading in the accurate measurement of the blinds. This would determine which clips you are going to need (mostly their size). Also, this is the same measurement that most people mess up!
Measurement: You can measure it using different means.
- A Depth Gauge
- A Store Loyalty Card
- A Credit Card
First, place the card against the glass. Now, slide it until it overlaps the glass. Mark the point with a pencil or a chalk. Now, simply use a ruler to measure the depth.
The Importance of Correct Beading Depth: If the beading depth is measured incorrectly:
- The brackets will be loose.
- The frame would disengage.
- The fabric would be in continuous contact with the glass.
Figure Out The Handle Projection
The window handles are the most annoying things that can ruin the beautiful look of your blinds and windows. That’s why it is important to measure the outward distance up to which the handle projects from the windows.
Place the steel tape against the frame. Now measure the outward distance to which the handle projects. Note the full distance. Now, make the adjustments according to the handle. If the handle is bigger, slim down the frame and brackets even more. Modify the frame type and size as well.

Check For Rubber Real Compression Space
Many modern windows have a rubber gasket. This is to prevent the dust, sand, and other allergens from penetrating into your space. If you are going for perfect-fit blinds, you need to give a little space to the rubber gasket. This is because the blinds’ fabric would press against the rubber.
- Press the rubber with your finger. If it compresses and bounces back — great.
- Measure carefully and opt for lightweight and slim frames if the rubber is rigid, hard, or has metal framing.

10 Common Measuring Errors | Avoiding Each One Of Them
Here’s what homeowners get wrong (and how to avoid it):
- Measuring the full frame instead of the glass: Only measure visible glass.
- Using soft tailor tape: Use steel tape only.
- Ignoring minor irregularities: Measure top, middle, bottom, and sides.
- Not checking beading depth: Use a gauge or plastic card.
- Forgetting handle interference: Measure handle projection.
- Rounding numbers: Perfect Fit blinds require exact millimeters.
- Not accounting for rubber compression: Check gasket softness.
- Estimating instead of noting: Record every measurement immediately.
- Measuring only once: Repeat each dimension twice.
- Misreading the tape: Use a digital tape if possible, or slow down and double-check.
You can avoid 99% of failures simply by not rushing
Pro Tips To Measure Window Blinds
- Warm the metal tape: To prevent shrinkage due to air conditioning in rooms.
- Clean the beading: The dust on the beading can affect the precise measurement of the depth.
- Record each measurement: Take a picture or record each measurement on a notepad.
- Measure twice: Be sure of the measurement. In case of uncertainty, measure the depth again.
Conclusion | A 10-Second Checklist Before Buying Blinds!
We are providing you with the checklist of everything you need to observe for a meticulous and precise blinds measurement for a perfect fit.
- Measuring width from 3 points.
- Measuring the height from 3 points.
- Always select the smallest measurement.
- Confirm the beading depth twice.
- Figuring out the handle projection.
- Check the compression of the rubber gasket.
- Precise measurement up to millimeters.
- Record everything in picture or written form.
Just make sure your measurements and the whole process revolve around these 8 points. If all of these boxes are checked, there is no way that you can mess up the accurate measurement for tailored fit blinds.
Frequently Asked Questions
What is the depth of perfect-fit blinds?
The most common brackets come in sizes that vary from 18mm to 30mm. The most common variation among these measurements is 8-14mm. This measurement is commonly used for the uPVC and aluminum windows.
How to measure for blinds inside recess?
Measure the width and the height of the window from three points. Top, middle, and the bottom for the width — left, center, and right for the height. Compare the three measurements on each axis and select the smallest reading.
How to measure perfect blinds for sliding doors?
The mount type used for sliding doors is the outside one. Measure the height and width from outside the frame from three points on each axis. Compare the three readings and select the largest reading. This will make sure that your blinds cover the entirety of the sliding doors beautifully.
What size are perfect fit brackets?
The most common sizes of the brackets include 18 mm, 20 mm, 22 mm, 24 mm, and all the way to 30 mm. These sizes fit in the window beads with different depths. You need to determine the exact measurement of your window for a tailored fit. You can use a depth gauge, a credit card, or a store loyalty card. Make sure to clean the beading before measuring.
