How to Measure for Roller Blinds?
Before installing, measure your window to make sure your blinds fit. You can install them inside the window frame (recess fit) or outside on the wall (face fit).
For Inside Mount
- Measure the width of the window at three places (top, center and bottom). Use the smallest number.
- Measure the height (drop) at two places. Use the smallest number.

For Outside Mount
- Measure from one side of the window frame to the other.
- Measure from the top to the bottom of the fram,

How to Cut Roller Blinds to Size?
Cutting roller blinds to fit your window might sound tricky, but it is actually quite easy if you follow these steps carefully.
- Decide Where Your Blinds Will Go: Choose where you want to place the brackets and install them on the window.
- Measure the Space Between the Brackets: Measure the distance between the brackets and add 2 cm (20 mm). This will be the new length of the top tube.
- Lay the Blind Flat: Roll out the blind on a table or floor. Gently slide the fabric away from the top tube and remove the end caps from the bottom rail.
- Mark Where to Cut: Use a pencil to draw a line where you need to cut the top tube and bottom rail. A piece of masking tape can help you cut in a straight line.
- Cut the Tube and Rail: Use a small saw to cut them to the right size. If there are any rough edges, smooth them with sandpaper.
- Measure and Cut the Fabric: Subtract 6 mm from the tube length (to make sure the fabric rolls up properly). Then, mark and cut the fabric carefully with scissors or a sharp knife.
- Put Everything Back Together: Slide the fabric back onto the tube and bottom rail, then put the end caps back on.
- Install the Blind: Now your blind is the right size. Snap it into the brackets, and you’re done.

Step-by-Step Guide How to Install Roller Blinds
Just follow these easy steps, and you’ll have them up.
- Measure Your Window: First, decide how you want to hang your blinds. Then, measure your windows to make sure they will fit.
- Attach the Brackets: Take a pencil and mark where you will place the two brackets—one on each side of the window. Make sure they are at the same height so your blind will be straight. A spirit level can help keep them even.
- Drill the Holes: Use a drill to make holes where you marked for the brackets. If your wall is made of brick or concrete, use the special plugs that come with your blinds.
- Secure the Brackets: Screw the brackets into place using a drill or screwdriver. Make sure they are tight so they don’t move.
- Cut the Blinds (If Needed): If your blinds are too wide, now is the time to cut them to the right size.
- Insert the Chain System: Put the ball chain system and end plug into each side of the roller blind tube.
- Attach the Blinds: Lift the blind and snap it into the brackets. Keep the blind rolled up to make this step easier.
- Secure the Cord: Attach the cord to the window frame using a screwdriver. This keeps it in place and makes it safe for small children. Do not use stick-on attachments, as they may fall off.
That’s it! Your blinds are now installed.

Frequently Asked Questions
Are roller blinds safe for kids?
Roller blinds are safe for homes with small kids if installed correctly. The cord should not make a big loop and must be high enough off the floor. Always attach the cord bracket securely to keep your family safe.
Should I install my blinds inside or outside the window frame?
Choosing how to fit your roller blinds is up to you and changes how they look and work. If you fit them inside the window, make sure they don’t block locks or handles. Pick the best fit for your home.
Can I change the side of the chain?
You can change the side of the roller blind chain easily. Just pick the side that works best for your room and place the parts on that end of the tube.
What is the difference between over roll and under roll?
There are two ways to roll your roller blinds. Over roll (forward roll) hides the top tube, and the fabric faces outwards. Under roll (backward roll) keeps the fabric closer to the window but shows the top tube.
What is the difference between single and dual roller blinds?
The only difference with dual roller blinds is the bigger bracket that holds them. These blinds stick out more, so they are best fixed on the wall, not inside the window frame. If you want both sheer and blockout blinds, you can put the sheer one inside the frame and the blockout one outside.
How do I adjust the length of the roller blind chain?
If your chain is too long and you need to make it shorter for safety, follow these steps:
- Pull the blind all the way up and mark the third ball down from the back of the chain.
- Roll the blind down to its lowest position. The chain between the top and your mark is the part you can cut.
- If your mark disappears when you roll down the blind, the chain cannot be shortened.
- Use pliers to cut the chain and reconnect the ends using the chain joiner provided.
