Whatever resolution you've got X set to, so yeah 800 if it's 800x600. And you do the same thing for the height: H = VR * 25.4 / 100. It's confusing because we're really not setting X up the way we're supposed to. What X expects is the physical width so it can calculate the real dpi based on the equation I gave first. Then it'll use that dpi figure to pick fonts the to use. But that's all based on the idea of a user sitting 30-50cm away from a monitor so it doesn't work well for TV setups because it'll result in fonts sized appropriately for some sitting 30-50cm away rather than 2+ metres or whatever. Net result is fonts that are too small. To avoid this problem we're giving X the width that would result in X calculating a dpi of 100 (which gives fonts of the right size for the rest of the interface).
