Do you take the with size into consideration while designing your website?
In my opinion if you code for 760px width, then adsense blends perfectly with this option.

What is your choice of concern as far as the pixel width is concerened?

You should always take care of width of an element on your webpage.
If you are to put nested tables into your HTML code, you may see that IE and Firefox is displaying your page differently if you do not use "width" attribute correctly. Always have an eye on it !

I tend to use 'liquid layouts' - coding with CSS make this very easy.

Tabled layouts take longer to load and are not as accessible but you can use percentages for width instead of fixed widths.

Basically, you do have to design for the lowest common denominator (800 x 600 res; Internet Explore-urgh) but if you have visitors with much higher resolution monitors, a fixed-width of say 750px looks ridiculous on their screen. Liquid layouts take care of this very easily to keep everyone happy.

I prefer to stick to the ever-popular 760px fixed width, that way I don't have to worry about content being "stretched" and making my page imbalanced.

At least until it's accepted that 1024x768 has become the "ideal" resolution.

Yes widhth is an important factor while designign a website I use 760px fixed width plus you have to create layout in such a way that it should look proper in all the resolutions and it should aligned center.

I allways like working with Fixed width... and 750 to 790 is a the key for developing as works good with both the 800x600 and 1024x768 resolution...

this always is a problem to me, because I always use a high resolution (1280X1024 I think it is) and most people use 1024x768 so the design is bigger for other than me. If you want something to take up the whole width of the screen without having to scroll for users with higher resolutions try using width=100%. This code can be quite useful
