In this article, we will not only answer the question “how many inches does Redmi 7A”, but also understand how this parameter relates to resolution, pixel density and real-world scenarios.
Many users mistakenly believe that screen size is the only criterion for choosing a smartphone by size. However, in practice, aspect ratio, matrix type, and even bezels thickness are important. We will analyze all these aspects, and compare the Redmi 7A with other models of the Redmi line and competitors from other brands.

Official screen specs Xiaomi Redmi 7A
The Xiaomi Redmi 7A screen size is 5.45 inches, a classic size for budget smartphones of 2019 that strikes a balance between compactness and easy viewing. It’s important to note that the manufacturer specifies the physical diagonal of the panel, not the usable display area (which may differ slightly due to rounded corners or cutouts).
In addition to diagonal, the key display options of the Redmi 7A include:
- 🔍 Pixel density (PPI): ~295 inches
Interestingly, despite its modest specs, the Redmi 7A has a Gorilla Glass 5 (most budget models of the time used Gorilla Glass 3 or similar), making it more resistant to scratches and minor damage from falls.
How does the 5.45 inch diagonal affect the user experience?
The screen size of 5.45 is a trade-off between several factors: on the one hand, it is convenient to hold with one hand, which is important for users with small palms or those who often use the phone on the go. On the other hand, for watching videos or games, this size can seem cramped, especially compared to modern devices with diagonals of 6.5 and above.
Let’s look at the pros and cons of this size:
- ✅ Compact: easily fits in a jeans pocket or small bag, weighing only 165g
- ✅ Ergonomics: You can reach any corner of the screen with your thumb (even with a small hand)
- ❌ Multimedia: When watching movies, black fields on the sides due to the aspect ratio of 18:9 (modern videos are more often 19.5:9 or 21:9)
- ❌ Multitasking: Less information is placed on the screen at the same time (for example, in a browser or messengers)
An important detail: the 18:9 aspect ratio means that the Redmi 7A screen is more vertically elongated than the older 16:9 models. This affects the display of content – for example, in games, interface elements can be cropped if they are not adapted to new standards.
💡
If you watch YouTube videos often, turn on the “Stretch” option in the app settings – this will reduce black fields, but slightly distort the picture.

How to measure the screen diagonal yourself?
If you already own a Xiaomi Redmi 7A and want to make sure the diagonal is accurate, you can measure it manually, you need a ruler or a roulette and a simple math calculation.
Measure the width of the screen (from left to right edge, without considering the frames)
Measure the height of the screen (from the top to the bottom edge, without considering the frames)
Put both values in a square and add the results
Extract the square root from the sum – this will be the diagonal in centimeters.
Transfer centimeters to inches (1 inch) = 2.54 cm)-->
Example: if the screen width is 6.5 cm and the height is 12.1 cm, then:
(6.5)² + (12.1)² = 42.25 + 146.41 = 188.66
√188.66 ≈ 13.73 cm
13.73 / 2.54 ≈ 5.41 inchesThe error of 0.04 inches is due to rounding and inaccurate measurement of the frames. For more accurate results, use a bar or special applications for measuring the screen (for example, Screen Ruler in Google Play).
