In HTML5 my game appears very small compared to the canvas

In HTML5 my game appears very small compared to the canvas. If I hit full screen the game looks good, and when I leave full screen the game will stay bigger but still not right. On my girlfriends computer it acts differently. I would like the game and the canvas to be the same right size. How can I do that?

I think that my game resolution is 1024x1024 (that is what my in-game camera is set to)

Here is what I ended up doing to fix this issue:
