Both the inner and outer displays use a Super Pixel arrangement, giving the Xiaomi 18 Fold full RGB sub-pixel layouts on both screens. This helps maintain sharp image quality while making the two displays more consistent with each other.
Another highlight is the brightness. Both screens are designed for strong outdoor visibility, with a peak brightness of up to 4,000 nits. This makes the Xiaomi 18 Fold easier to use in bright environments, whether you are indoors or outside.
The rear panel features a clean and minimalist look. Xiaomi places the Leica triple-camera system inside a rounded, racetrack-shaped camera module that gives the phone a distinctive appearance without making the design feel overly busy.
A closer look at the camera module reveals a subtle Leica inscription engraved around the upper section of the outer ring. The branding is understated and only becomes obvious when viewed up close.
When unfolded, the Xiaomi 18 Fold measures 163.8 x 117.9 mm. Its proportions make it practical to use horizontally as a compact tablet, while users with larger hands can also hold it vertically like an oversized candybar smartphone.
One of the biggest advantages of this design is its slim profile. The device is just 5.02 mm thick on one side and weighs approximately 219 grams. That makes it lighter than many conventional flagship smartphones and significantly more portable than most large foldable phones.
The speaker system is positioned at both ends of the same side, creating a more balanced stereo effect when the phone is used horizontally for gaming or video playback. The SIM card tray is located along the top edge, while the USB-C port sits in the center of the bottom edge.
The metal frame has a fine frosted texture that gives the phone a smooth and refined feel in the hand. Xiaomi also uses the same finish for the power and volume buttons, helping the entire frame maintain a consistent appearance.
Folded Size and One-Handed Use
When folded, the Xiaomi 18 Fold measures approximately 117.8 x 83.6 mm, giving it a compact and easy-to-handle shape.
Although the folded device looks short and relatively thick, its width is only slightly greater than that of a typical flagship smartphone. This allows it to sit comfortably in one hand.
Its shorter height also improves one-handed usability. Tasks such as typing, checking notifications, scrolling and swiping back can be performed without constantly repositioning the phone.
The folded Xiaomi 18 Fold is roughly comparable in size to an A7 sheet of paper, allowing it to fit easily into a suit pocket or some larger shirt pockets. Its compact footprint also makes it convenient to carry throughout the day.
Despite being a foldable device, it measures only 10.68 mm thick when closed. As a result, it avoids the bulky feel commonly associated with larger foldable smartphones.

Overall, the Xiaomi 18 Fold focuses heavily on portability, slimness and one-handed usability. Its mid-fold design gives it a distinctive identity among foldable phones, while the lightweight construction and compact folded dimensions make it easier to carry than many larger foldable models.
Mid-Foldable Screen Experience
One of the most interesting aspects of the Xiaomi 18 Fold is its approach to screen proportions. The inner and outer displays use a 2:1 aspect ratio, creating a consistent layout across different screen sizes. Apps, icons, and widgets remain arranged in familiar positions whether the phone is folded, partially opened, or fully unfolded. This makes switching between display modes feel intuitive and avoids the layout changes that can sometimes make foldable phones confusing to use.
The unfolded screen is also surprisingly compact compared with a traditional tablet. Placed beside an A5 notebook, the Xiaomi 18 Fold occupies roughly half its footprint and is closer in size to an A6 sheet of paper. When folded, it becomes approximately A7-sized, giving it a compact form factor similar to a small notebook or even a passport.
That compact design does not make the outer display difficult to use. In folded mode, the phone is slightly wider than a conventional flagship smartphone, which provides enough space for comfortable one-handed operation. The 26-key keyboard layout also benefits from the added width, making typing feel less cramped.
A 1.414:1 Display Ratio for Everyday Content
The Xiaomi 18 Fold uses a √2:1 screen ratio, which works out to approximately 1.414:1. This is wider than the traditional 16:9 format commonly used for video content. As a result, watching 16:9 videos may leave small black bars around the image, although they do not significantly affect the overall viewing experience.
The extra screen area becomes more useful with other types of content. For example, many vertical short videos use a 3:4 format, allowing them to fill more of the display. According to the supplied specifications, this helps the Xiaomi 18 Fold achieve a screen-to-body ratio of up to 95.2%.
Photography is another area where the unusual aspect ratio can be useful. When viewing 3:2 photos, as much as 93.3% of the screen can be used for displaying the image. This makes the large inner display particularly useful for reviewing photos without wasting too much space.
The √2:1 ratio is also closely aligned with standard international paper sizes. That makes the Xiaomi 18 Fold especially practical for reading documents, working with PDFs, and handling office files. A standard A4 document can be displayed at the same proportional ratio, reducing the need for excessive cropping or scaling.
For users who frequently read documents or work while traveling, this design gives the Xiaomi 18 Fold an advantage over foldable phones that prioritize video playback alone. Although 16:9 movies and long-form videos may not take up the entire display, the wider range of supported content makes the screen more versatile for everyday productivity.
Tablet-Style Productivity on a Foldable Phone
Xiaomi has also optimized the inner display for applications designed for larger screens. Several productivity apps can take advantage of the expanded layout, providing an experience that is closer to using a tablet than a conventional smartphone.
The Xiaomi 18 Fold comes with five PC-level applications. These include WPS For Pad and CapCut Pro, along with Wind Financial Terminal PC, ZWCAD, and CNKI CAJ. The inclusion of professional software makes the foldable more useful for users who need access to documents, design tools, financial platforms, or research materials while away from a desktop computer.
Some of these professional applications are better suited to a larger input method. Connecting an external keyboard can make longer documents, spreadsheets, and other desktop-style tasks considerably easier, just as it does on a conventional tablet.
A Better Fit for Multitasking
The larger inner display gives the Xiaomi 18 Fold more room for multitasking. Applications designed for tablets can take advantage of the additional width, while split-screen functionality allows users to work with multiple types of content at the same time.
For example, Xiaohongshu can use a three-column layout similar to a tablet interface, making browsing more engaging on the larger panel. Split-screen mode can also place images on one side and comments on the other, allowing users to view more information without constantly switching between pages.
Overall, the Xiaomi 18 Fold’s screen is not simply a larger smartphone display. Its compact folded size, practical aspect ratio, high screen utilization, document-friendly proportions, and tablet-style software support make it a versatile option for both entertainment and productivity.
The display may not be perfectly optimized for traditional 16:9 video, but its broader usability makes up for that limitation.
