I was taught it was two. A good way to remember this is by counting the dots on it. The colon has two so it has two spaces. A semi colon has only one dot, and it has only one space after it.
But this only applies when the name of the punctuation has the word "colon" in it, as when you are counting the dots in a period, you only see one, but after a period, you usually put two spaces unless you are using a wesite address or something of that sort.
In typing, proper style is 2 spaces after a period (.), as well as after a colon (:).
1(:
One space after a semicolon.
There is one space after a semi colon: Example: I went to the store and forgot coffee; potatoes and milk.
There should be one space after a semi colon.
