Make your selection, look at the dimensions of your selection in the info palette, multiply the width by the height...Thats it.

weed i dont think its going to be that straight-forward . this will only work if the selected area is a rectanle/square (lxb = area) . it surely wont work for random / circular shaped selections

Nope, it wont. And good luck..heh. I dont think it can be done. Photoshop certainly doesnt do it.

Photoshop does not count the pixels. I also needed to know how many pixels were in a given area and the only way to figure it out fast was using this formula.

(w x h) x 0.78601618162057722497282936843376 = number of pixels. (give or take a pixel or two)

Time to read the guidelines on posting comments and answers khourykris. Especially when giving an answer that doesnt make sense.

Found the answer, I think:

Fill selected aria with black,
everything else - white, then
Image > Histogram and when cursor in
the Histogram window,
Percentile show percent of the selected aria.
