How much space does a lemon or orange tree need to grow?

Question:

Answers:
This is a very vague question, since i have no clue what type of lemon or orange.
Lemon and lime can be miniature and only get to about 3-4 feet and can be in a medium size pot. But full size lemon tree such as Eureka need 12ft spacing. Full sized Orange tree can grow up to 30ft wide.
So best bet is that you know your tree cultivate variety then ask again.
