I often use the bottom left of the sprite as the origin, but always have 0 at the top and 255 at the bottom or closer to that if I've trimmed the screen or possibly have a status bar.
On the beeb I nearly always borrow the screen to 224 (displayed, still 255 wide) or 255 to match the arcade and to reduce the maths, although lookup tables would probably be faster
