One other note on total number of stitches; if every square of a pattern is stitched, then yes it is just width x height. If the background isn't stitched though, it may be less. If there's a KG-chart file, it will tell you the number of stitches. The following picture has the key info circled:

Notice 90 x 25 would be 2,250, but the count is only 807 because the background isn't stitched.
If there isn't a kg chart file and I can tell the background isn't stitched, I usually just leave that line blank.
