How much outdoor space do cats need?

This will depend on the cat. If the cat is used to being an outdoor cat and has previously roamed free, then it will adjust faster to a cat run if it is larger in size.

If your cat is predominantly an indoor cat and you are looking to provide it with some outdoor time, a smaller enclosure such as a portable enclosure would suffice.

Each cat should have a minimum of 2 square metres of space as a rough rule of thumb, plus access to other enclosed areas or indoor access.
