The Xiaomi 14 Ultra has a fixed, non-folding form factor measuring 161.4 × 75.3 × 9.2 mm and weighing 219.8 g. It carries an IP68 waterproof rating, meaning it is fully protected against water ingress under the conditions that certification covers. The build is not classified as rugged, so while it handles water exposure, it does not carry additional reinforcement associated with ruggedized devices. Overall volume comes in at approximately 111.81 cm³, reflecting a relatively standard slab-style smartphone footprint for a device of this screen size.

The Xiaomi 14 Ultra uses an OLED/AMOLED touchscreen measuring 6.73″ with a 1440 x 3200 px resolution and a pixel density of 521 ppi, delivering a sharp and detailed image across the panel.
