Yes, if you are skilful and can invest the time. My door is 70 cm wide and 192 cm high. I unravelled the Velcro on both sides, adjusted the width and also cut off the excess at the bottom. Then neatly sewed the sides on with the sewing machine. It's tip-top. I also had to adjust the adhesive tape, didn't have a frame of 2.5 cm. Have fun :-)

Sorry, not yet installed. But the way it sounds, you would have to glue the cut Velcro edge back on, I can imagine.

Basically it can be cut, but then the edge with the Velcro fastener is gone - will it still hold?
