When it comes to choosing Xiaomi equipment, one of the key parameters is the screen size. The manufacturer traditionally specifies the diagonal in inches, but for many users it is much more convenient to operate with centimeters. For example, when buying a cover, protective glass or planning a space for a Mi TV TV Knowing the exact dimensions in cm helps to avoid errors, but not everyone knows how to convert inches to centimeters correctly or where to find official data on a particular model.
In this article, we will examine not only the standard ways to translate inches into cm, but also nuances that are often overlooked: for example, why the real width of the case of a Redmi Note 12 smartphone can differ from the calculated screen diagonal. You will also learn how to measure the screen yourself (even if there is no ruler at hand), where to find the official Xiaomi specifications, and why some TV models have a diagonal in cm indicated with an error of up to 1-2 cm. For convenience, we have prepared current matching tables for popular devices in 2022-2026.
Why Xiaomi is diagonal in inches, not centimeters
The tradition of measuring screen diagonals in inches comes from the United States, where this unit of measurement is standard for electronics. Xiaomi, like other global brands (Samsung, Apple, Sony), follows this rule to unify technical characteristics in the international market. However, in Russia, Europe and most of the CIS countries, the population is accustomed to the metric system, so the translation of inches into centimeters becomes an urgent task.
It's important to understand that the screen diagonal is the distance between opposite angles of the matrix in a straight line, not the width or height of the device. For example, a Xiaomi 13 smartphone with a diagonal of 6.36" in centimeters will have a screen of about 16.15 cm, but the body itself will be wider due to the frames, which is often a cause of confusion when choosing accessories.
- 📏 1 inch = 2.54 cm - Standard translation coefficient approved by the international system of units (SI).
- 🔍 In the specifications of Xiaomi, the diagonal is always rounded to tenths (for example, 6.7, not 6.67").
- ⚠️ At Mi TVs. TV redmi TV the real size of the body can exceed the screen diagonal by 5-10 cm due to the frames.
Interestingly, China also uses the metric system, but electronics still prioritize inches, due to historical reasons and display standards, such as the factories that make Xiaomi matrices calibrate equipment to inch sizes, which simplifies logistics and component compatibility.
How to convert Xiaomi inches into centimeters: formula and examples
To translate the screen diagonal from inches to centimeters, a simple formula is used:
Centimeters = Inches × 2.54For example, for a Poco smartphone X5 Pro with a diagonal of 6.67" calculation will be as follows:
6.67 × 2.54 = 16.94 cmHowever, in practice, many users face two problems:
- Rounding: Xiaomi often specifies diagonal with error, for example, the real diagonal of Redmi Note 11 is 6.43", but in marketing materials can appear as 6.4".
- Screen frames: even if you know the diagonal in cm, it's hard to predict the dimensions of the case. 12T screen 6.67" (16.94 cm), but the width of the device is 75.95 mm (7.6 cm).
To avoid errors, we recommend using accurate data from the official specifications (for them in the next section).
| Diagonal (inches) | Diagonal (see para. | Example of Xiaomi model |
|---|---|---|
| 5.8" | 14.73 | Xiaomi Mi 11 Lite |
| 6.4" | 16.26 | Redmi Note 10 Pro |
| 6.67" | 16.94 | Poco F4 GT |
| 6.78" | 17.22 | Xiaomi 12 Pro |
| 7.9" | 20.07 | Xiaomi Pad 6 |
Where to find official Xiaomi sizes in centimeters
The most reliable way to find out the exact dimensions of the device is to consult official sources. Xiaomi publishes technical specifications on several platforms:
- 🌐 Global site: mi.com/global → The "Specs" section for each model, for example, for Xiaomi 13T Exact body sizes are indicated: 162.8 × 75.7 × 8.6 mm.
- 📄 Documentation in a box: complete with the device is a booklet with specifications, where sometimes duplicated dimensions in cm.
- 🛒 Product cards on the Mi Store: in the section "Technical characteristics" can be specified dimensions in millimeters (1 cm) = 10 mm).
If you don't have a cm size on the site, you can calculate it yourself, knowing the dimensions in millimeters. 12 Pro+ hull sizes: 162.9 × 76 × 8.9 To translate into centimeters, divide each value by 10:
Width: 76 mm = 7.6 cm
Height: 162.9 mm = 16.29 cm⚠️ Note: There are fakes on the market for Xiaomi, where the actual sizes may differ from the stated.Always check the device by serial number through the official Mi Verify app.
For Mi TVs, TV redmi TV The situation is more complicated: the manufacturer specifies the screen size (for example, 55), but does not always publish the dimensions of the case, in which case manual measurement (for this in the next section) or data from partner sites, for example, the section will help. TV mi.com.
How to measure the screen Xiaomi yourself (even without a ruler)
If you don't have official data on hand or want to double-check the dimensions, you can measure the screen manually, which will require a ruler, a roulette or even a regular sheet of A4 paper (its width is 21 cm, which can serve as a guide).

If there is no rule, use alternative methods:
- 📏 Bank card: its standard width is 8.56 cm.Apply the card to the screen and count how many cards are placed diagonally.
- 📄 A4 sheet: fold it diagonally (length of the diagonal sheet - 35.4 cm) and compare with the screen.
- 👆 Palm size: in an adult, the distance from the base of the thumb to the little finger in a sweep is about 20 cm.
⚠️ Note: When measuring Xiaomi TVs, do not press on the screen – matrixes with technology OLED or QLED sensitive to mechanical effects.
Measurement applications such as the Ruler App (available on Google Play) can be used for maximum accuracy, but note that these programs often give an error of up to 0.5 cm due to the camera calibration.

Top.-5 Mistakes in determining the screen size of Xiaomi
Even experienced users sometimes make mistakes when trying to find out the diagonal of a Xiaomi device in centimeters, we have collected the most common of them:
- The screen size is confusing. For example, Xiaomi 13 Lite has a screen diagonal of 6.55" (16.64 cm), but the width of the body is 72.7 mm (7.27 cm) The difference is almost 1 cm!
- Ignoring rounding. The manufacturer can say 6.7" while the real diagonal is 6.67." A 0.03 error gives a difference of 0.08 cm.
- They don't take into account the type of matrix. TV with curved screens (Curved) the real diagonal at the edges may be less than the declared 1–2 cm.
- There are many Xiaomi clones on the market (for example, fakes under Redmi), where the screen sizes do not match the original.
- They forget about the TV frames. TV Q1E with a diagonal of 55" (139.7 cm) has a real width of the body of 123 cm - almost 20 cm more!
To avoid these errors, always check the official specifications or use proven measuring tools. If you buy a case or protective glass, pay attention to the mark "exact cutout" - this means that the accessory takes into account the real dimensions of the device, not just the screen diagonal.
