Adjusting picture/pixel sizes proportionally


I have to resize a lot of pictures - luckily resizing tools tend to do the math for me in terms of keeping picture dimension in proportion - so if I resize a picture from 2000pixels wide to 687, it automatically works out the height. However, when I embed videos I often have to do this myself. It would be very useful to have a simple calculator where I can input the current dimensions of a video (say 900px x 425px), input the desired height/width, and it makes the calculation for me.

This is also a way for me to give you my email address, which is You may have got this from the site, but because I have been signing in via FB maybe not.

Many thanks
