Auto maximize for each website

[GTghost]

I got a question about maximize chrome to best settings for each page. It's hard to explain but I'll try my best. Say I have the browser maximized to fit best size for website X which is 800px wide, then I go to website Y which is 1200px wide but the browser is still 800px. So to get it at 1200px, I have to click the green maximized button. My question is there any way to have it maximize by itself?

I created a shortcut so when I hit cmd+up it maximizes. But I am still looking for an automated process.
