It’ll do. Even though it measures out to be wider than my door frame, it definitely does not fit it. Not only did I have to make sure the Velcro on the top bubbles around the middle so the gap at the top is minimized, all the way down the sides I had to gradually move the Velcro inwards in order for it to fit and close. I did expect some moving it inwards but not to this extent. I do have to close it every time passing through as well. The gap at the top is definitely large enough for any bugs to come in and that does defeat the purpose of it in the first place. At least the pets think it’s a closed door so they don’t go outside. You do get what you pay for with this.
