Round by round
8.0 inches inside and 6.5 outside, against 7.6 and 5.4. The Ultra's tall cover screen feels like a normal phone.
Three cameras with a 200MP main and a 3x telephoto, plus 8K video. The Duo has two 48MP cameras and no telephoto.
215 g against 254 g. That 39 g is about six loonies, and the Ultra is thinner open and closed.
IP68 against IP48. The Ultra survives water, but its rating doesn't cover fine dust or sand.
Apple rates the Duo at up to 44 hours of video on the outer screen. Samsung rates the Ultra at up to 27. Different tests, so treat it as a guide.
On paper the Ultra wins. But if you're on iPhone, the Duo is the only one of these that fits your life.

SOur take
The Fold8 Ultra is the best foldable we sell right now: biggest screens, best camera, and lighter than the Duo.
The Duo's case is simple: iOS and IP68. If you're an iPhone person, that matters more than an extra half inch.
