jQuery HD Aspect Ratio Tool
A few months ago I developed a simple but effective little web page with some javascript and jQuery that would allow me to determine, based on a width, a 16:9 aspect ratio. I found myself always having a specific width from a content area and I wanted to determine the video size I could fit in there. Problem was, I didn't want to waste time calculating the all important aspect ratio from the width I had.
I searched the net and couldn't find anything useful, so I built one myself:
This was just whipped together quickly and I found it useful. I’m pretty sure it could be tweaked, but it fits its purpose as is right now. Let me know if this helps you at all. enjoy.
