The Mi 11 uses Corning Gorilla Glass Victus on its display and Corning Gorilla Glass 5 on its back or vegan leather depending on the model. The front of the phone uses a hidden earpiece. The  back of the phone has two material designs and five available colours: black, white, blue, smokey purple, and brown. The first three use anti-glare glass and the latter two use vegan leather. Due to the varying materials, the thickness and weight of the device are also different. The anti-glare frosted glass version is 8.06 mm thick and weighs 196 g, and the vegan leather version is 8.56 mm thick and weighs 194 g. The side frame of the Mi 11 is made of an aluminum alloy, and there is a communication antenna overflow band around the fuselage, which  is filled with plastic injection molding with a colour similar to the frame. The upper part of the frame is equipped with a noise reduction microphone, an infrared emission window and a top sub-speaker (integrated earpiece function). The right side is equipped with a plus and minus volume buttons and a switch screen/power button. The lower part is equipped with a SIM card slot and ejection jack, a USB Type-C interface and the main speaker openings. There is no opening on the left side. The frame becomes wider near the control buttons. The back of the Mi  11 is made of AG-processed glass or leather-like polycarbonate plastic. The glass-based version of the back cover is about 2g heavier than the polycarbonate version, but the total thickness is reduced by 0.5mm. The upper left corner of the back cover contains the rear camera group area, which is contained in rounded rectangle. The left side of the camera area is a Nascar racetrack-shaped black area, with the main camera sensor placed on the upper part and the wide-angle sensor on the lower part. There is a bright silver ring on the periphery  of the main camera sensor opening, which is slightly protruding, which echoes the design of Mi 9, Mi CC9 and other models. The right side of the racetrack-shaped area is a silver area, from top to bottom, long-focus macro sensor, LED fill light and auxiliary ambient light sensor are arranged.
