Introduction: Cutting an IKEA Hoppvals Cellular Blind

This Instructable describes resizing an IKEA Hoppvals Cellular Blind. The Ikea site states that it is not adjustable by cutting, I only found this out after I bought the blinds (admittedly on the cheap, £11 heh, heh).

I had the previous Bruddans Blinds from Ikea and they could be cut by about 100mm, but as they say, never assume.

Obviously this process is going to invalidate your warranty, but these blinds cost £25 ($34, 28 Euro) and the nearest I could find for fitted blinds came to £84 (the most expensive was nearly £400, I might do this for a living).

The Hoppvals blind has the spring mechanism very close to the end of the top frame leaving no room for adjustment. I had already bought the blinds so what to do...

Step 1: Top Frame

The spring assembly which lifts the blind is about 30mm from the end, I don't think I could cut that and still be usable. The other end is much the same.

First thing: take off the end caps and put them somewhere safe.

Step 2: The Spring Assembly

The Spring assembly is held in place by tension against a small bulge in the top frame

I pulled the Spring Assembly out to the end and let it rest, the whole thing is under a lot of tension so be careful.

Step 3: Bending the Front Tab

Take your pliers and bend the front tab on the Spring Assembly so that it is flat and will pass over the bulge in the top frame. The rear tab will catch instead moving the Assembly 80mm along the frame.

Step 4: Reseating the Assembly

The Spring Assembly is 80mm closer and this has released quite a bit of tension. Before putting the Assembly back in tie up 80mm (2x40mm) of the cord near to the central pulley block.

Remembering the tension in the spring, pull the Assembly to the end of the frame and carefully put it back in the top frame. DON'T LET GO! It will pull quite strongly. Slowly move it back until the rear tab stops it against the bulge in the frame.

Voila! I now have 80mm (3"1/8) to play with.

Step 5: Cutting Time

Line up the top and bottom frames with the blind material at the cutting end.

The blind should be shorter, leave the difference at the uncut end. Mark off how much you want to cut.

Pull the frame back. cut the material with a scalpel, bread knife or hacksaw.

Take some card (I use the packaging) and bind up the whole blind with tape to protect the finish whilst sawing.

The frames are aluminium, a junior hacksaw would do. I couldn't find mine so I used a jigsaw with a bimetal blade, a bit of overkill.

Step 6: ...Add Tension

Put on the end caps and try out the tension on the blind.

You should be able to easy pull down the blind, have it stay in position, and push back up again with a finger, again staying in the closed position.

I also cut the support brackets to fit the blinds very close to the window.

And now I have to fit them. Enjoy.

    Thanks for this useful article. I'm heading to IKEA when they open today. I spotted this blind. Just to confirm, the end caps are removable, the mechanism is 30mm from the edge. I need my blind to be 975 wide. I'm good to go I take it? Also, would you say it is okay just to cut one side of the blind?
    Many thanks
    Martin

    Hi,
    Sorry I didn't see your message.
    You are correct on all points.
    The end caps pop off and you don't have to replace them.
    The end that has the lifting mechanism is 30mm from the end. This is the "simple" cut and should get a 1 metre blind down to 975mm quickly, no need for further fettling.
    But this is old news, and you probably know all this by now!
    Hope it went well.

    Thanks, KennR. They didn't have the 1 mt. blind. I ended up getting a roller blind with a stick control. It was easy enough to cut.

    Hi, the "top" frame is 40mm deep, the rest is 30mm.
    As for mounting the blind sideways, these blinds have no internal support to hold them up.
    I can imagine drilling a small hole top to bottom and feeding a steel cable through, like a curtain wire, screwed into your frame. However the material the blinds are made is non-woven and not very strong, like a thick paper. It would probably tear.
    The Hoppvals is pretty cool but for a campervan (or a 3-man boat!) , curtains or roller blinds are likely your best bet.
    All the best.

    Question 8 months ago

    Hi - Thanks for posting; this is a huge help. A question: I need to cut off about 5.5 inches (140mm). Do you think the other side has enough depth to do your process on both ends? Ie to remove 70mm from each end? Thanks!

    Hi,
    I don't think 140mm is possible. A maximum of 80mm using my method, but the other end looks like a difficult rivetting/stringing task.
    This chap on youtube appears to be doing that;
    "How to shorten / resize an IKEA HOPPVALS"

    I don't know if Instructables allows youtube links.
    Best of luck.

    Excellent work, this worked like a charm. My house came with these blinds on two different sized windows in the main room. One was mounted inside the window frame and the other outside as it was too long. Drove me batty. A hacksaw for the aluminum and a sharp utility knife for the blind material worked best.
