I put my 997.2 into my standard single garage virtually daily. The door opening is 7ft (2.13m) wide and the inside wall to wall width is 8ft (2.44m).
It's simply a matter of getting used to reversing in at a slight angle of approach through the door aiming the car towards the passenger side back corner of the garage. painting a white vertical line down this corner of the garage helps.
With a little practice it's easier than parallel parking because you have the wing mirrors to judge an even approach and later the mirror tips when 75% in.
As suggested already I have a thick piece of carpet fixed with battens to the wall adjacent to the driver door.
There is very adequate room to get in and out of my car this way
