When looking for accessories for your smartphone or comparing the characteristics of different models users are often interested in specific digital information. the question of how many centimeters is the length and width of the Xiaomi Redmi Note 7 phone, becomes especially relevant when buying a protective glass or case in offline stores where you can not try on the accessory virtually.
This device, which has become a real hit in its price segment, has an ergonomic body, which many people think is more or less because of the design of the frames and the diagonal of the display. Accurate knowledge of the geometric parameters of the device is necessary not only for the selection of accessories, but also for assessing the usability with one hand, which is critical for modern overall smartphones.
In this article, we will take a detailed look at all the physical parameters of the body, translate inch values into familiar centimeters and compare them with other popular models, you will get comprehensive information about how dimensions affect ergonomics and why the manufacturer's stated dimensions may differ slightly in reality.
Official dimensions of the body and their translation into centimeters
The manufacturer specifies the exact specifications in the documentation, but the units of measurement there may vary. For the Redmi Note 7 model, the standard data are values in millimeters, which are easily converted to centimeters for more visual perception. The height of the device is 159.21 mm, which in the decimal number system is 15.92 cm.
The width of the case, which is a critical parameter for palm coverage, is 75.21 mm or 15.21 cm. This value determines how comfortable you will be typing with your thumbs, holding the phone in one hand. The thickness of the device is 8.1 mm (0.81 cm), making it thin enough for a device with a capacious battery, but not the most compact in the class.
It is important to understand that these numbers refer to a "clean" case without taking into account the protruding elements. The camera, speaker and control buttons can add additional millimeters that are not considered in the basic specifications.

When buying a bookcase, keep in mind that the interior of the cover will add another 1-2 mm to the total thickness of the device in the closed state.
Below is a table that systematizes the main linear dimensions of the device for quick familiarization:
| Parameter | Value in mm | Value in cm |
|---|---|---|
| Height (length) | 159.21 mm | 15.92 cm |
| Width | 75.21 mm | 7.52 cm |
| Thickness | 8.1 mm | 0.81 cm |
| Weight. | 186 | - |
Screen size and the impact of frames on overall size
The central element of the front panel is a display, whose diagonal is 6.3 inches. When translated into the metric system, we get a value of about 16.0 cm. However, this distance is measured diagonally between opposite angles of the luminous region, and not the physical body.
The screen ratio in the Xiaomi Redmi Note 7 is 19.5:9. It is an elongated format that allows you to increase the usable display area without making the smartphone too wide. It is thanks to this aspect ratio that the width of the device remains comfortable - about 7.5 cm, despite the impressive diagonal.
It's worth noting that there's a so-called "drop" cutout at the top of the screen for the front camera, which has reduced the top frame compared to previous generations, which used a full bang. However, the bottom frame ("chin") is still present and takes up several millimeters of usable space.
β οΈ Warning: When adhesives to a protective glass, make sure it is labeled "Full Coverage" or "3D", Because the screen has rounded edges (2.5D), and flat glass may not stick to the edges or move away.
The area of the screen relative to the total area of the front panel is about 81.4%, a high figure that provides a sense of βframelessnessβ, although the device remains quite large physically. For comparison, the 5.5-inch models of the same year were much smaller.
Ergonomics and ease of use with one hand
The 15.92 by 7.52 cm dimensions put the Redmi Note 7 in the category of large smartphones, which are the most natural scenario for two-handed control. However, engineers tried to make the back cover and side faces as easy as possible to grab.
The back panel has a rounding on the sides, which visually and tactilely reduces the perceived width. When you take the phone in your hand, the fingers are not covering a rectangular parallelepiped, but a more organic shape, which allows you to hold the device more confidently, even if your palm is not very large.
The location of the fingerprint scanner on the back also affects ergonomics. Depending on the size of your hand, the finger may reach the sensor in a natural position or require a slight grip shift. The weight of 186 grams is felt palpably, but is not critical for long-term use.
- π The width of 7.52 cm allows most users to reach the opposite edge of the screen with their thumb.
- π 19.5:9 elongated format makes it easier to scroll through social media feeds with the thumb of one hand.
- βοΈ The uniform distribution of mass prevents rapid fatigue of the hand during long conversations or games.
For people with small palms, using one hand can be difficult, especially at the top of the screen, and manufacturers offer special software solutions such as a one-handed mode that reduces the image to the size of a smaller screen.
Comparison with competitors and other Xiaomi models
To better understand the scale of the device, it is useful to compare its size with other popular models of the same period and direct competitors.
For example, the predecessor in the face of the Redmi Note 6 Pro had almost identical dimensions, but a slightly smaller screen diagonal due to the wider bezels. At the same time, more modern models of the Redmi Note 8 and Note 9 series have become even more elongated, retaining about the same width, but increasing the height to 16 + cm.
Comparison with iPhone
Letβs look at the comparison table with the nearest competitors in the budget and middle segment:
| Model | Height (cm) | Width (cm) | Diagonal |
|---|---|---|---|
| Xiaomi Redmi Note 7 | 15.92 | 7.52 | 6.3" |
| Honor 10 Lite | 15.48 | 7.36 | 6.21" |
| Samsung Galaxy A50 | 15.85 | 7.47 | 6.4" |
| Xiaomi Redmi Note 8 | 16.13 | 7.64 | 6.3" |
As you can see from the data, the Redmi Note 7 is in the middle of nowhere. It's not as wide as some of its competitors, which makes it more convenient, but it's not so small as to sacrifice the size of the matrix. The Honor 10 Lite, for example, is smaller, but it loses diagonally.
The impact of accessories on the final size
When you buy a phone, you almost certainly get protection for it, and that's where the physical properties of materials come into play, which can change the initial centimeters, and silicone, plastic and hybrid cases add their millimeters.
A thin silicone case (plate) will add about 1-2 mm to the width and length, and 2-3 mm to the thickness. Thus, the width of the smartphone in silicone will be about 7.7-7.8 cm. This is a minor change that has almost no effect on ergonomics.
Protective book covers or hybrid cases with reinforced angles (called "anti-falls") can increase the dimensions more significantly, the thickness of the side faces can grow to 1 cm or more, and the total weight of the device will increase by 30-50 grams, which turns the compact device into a heavy shovel.
β οΈ Warning: If you plan to use the phone in a car holder with a fixation on the sides, be sure to consider the thickness of the case.In a thick protective case, the phone may simply not fit into the standard clamp.
Tempered glass on the screen also has its thickness, usually 0.3 to 0.5 mm. Although this seems negligible, combined with a thick case that has raised sides to protect the screen, the glass can create a rainbow effect on the edges or interfere with swipes if the case is picked up incorrectly.
βοΈ Selection of cover by size
Technical nuances: IR port and connectors
Speaking of size, you can't ignore the location of the ports, because they take up space on the ends of the case. In Xiaomi Redmi Note 7, there's an IR port on the upper end, which is rare for modern smartphones. It doesn't affect the dimensions, but it's important when choosing a case - the hole should be exactly in the center.
On the lower end are the 3.5mm headphone jack, USB Type-C port and speaker, and the elements are symmetrically positioned relative to the central axis, allowing the cable to be used in any position, but the presence of a protruding main camera module on the back (which is not completely sunken, but has a protective ring) adds thickness to the phone at the protrusion point.
The camera's protrusion is approximately 1-1.5 So, if you put the phone on a flat table without a cover, it will sway slightly when you press the opposite angle.

The exact dimensions of 15.92 x 7.52 cm are only relevant for the βnakedβ device; any case will increase these values, which is critical for the selection of accessories.
