Question

Answer 1

It's hard to guess the exact size that your Git repository will take because it depends on several factors, for instance

• type of stored objects
• number of branches, tags
• number of similar/duplicate objects

Git has a good compression algorithm and, from my past experience, it was able to reduce the size of a SVN repository up to 10 times. Here's some examples.

However, the best way is to try it yourself. On your local machine you can convert the SVN repository into Git

$ git-svn clone -s http://path/to/subversion reponame

then run git gc and see how much space you need to start.
