How to Find Out Your Laptop Screen Size Without Measuring

Laptops come with a wide array of screen sizes. These screens can measure at a range of 11 inches to as big as 30 inches, rivaling TV screens. However, most manufacturers stick to the 11.6 to 17-inch range whenever producing laptops. Generally, a larger screen translates to a heftier price tag. While we can buy the most significant screen there is to have a full field of view and to have a more immersive experience as we consume different content; there are some factors to consider such as portability and weight.


Most of the time, consumers buy their laptops without determining the size of the screen.  While this is not much of an issue, some instances require knowing the size of the laptop display. We hear a lot of cases wherein consumers bought the wrong sized screen when they try to place them inside their laptop bags- they are either too bulky or large.

With this, we will teach you how to find out your laptop screen without measuring. Moreover, we will also highlight some factors that you need to look into aside from the size of the screen.

One of the most natural ways of knowing the size of the screen is by manually measuring it using a measuring tape or ruler. To do this, you need to take hold of a measuring device, preferably a measuring tape.  Measure the screen diagonally starting from the left portion of the screen down to the right bottom corner. When measuring the screen, you should not include the bezels or the black part, just the display. When you don’t have a measuring tape or ruler with you, you need to look into some other alternatives which we will tackle in this article.

Determining the Screen Size

At this juncture, we will discuss to you the other means of determining the size of your laptop screen.

Know the Model Number

All laptop units come with their unique model number. You can use the model number to determine relevant information about the laptop, including the screen size. For example, an Acer laptop with a model number of S291HL has a screen size of 20 inches. You will be able to know the screen size instantly through the figure “20” which came after “S.” Generally, laptop model numbers start first with one or two letters preceded by a number. The amount that comes after the first few letters usually denote the size of the display.

Review the Specifications

Another method of determining the screen size is by taking a look at the specifications. You can do this by checking the manufacturer manual or even the box that came with the laptop. You can also check the specs online search for the model number, and the results should begin with the screen size information.

Other Aspects to Consider

Aside from the size of the screen, there are also some other aspects you need to take into consideration.

1. Screen Resolution

Screen Resolution is the term used to denote the number of pixels being packed into the areas of the display. Most laptops come with resolutions of 1920 x 1080, while cheaper options come with 1024 x 720 decisions. To make the term more natural to understand, most manufacturers shorten them to FHD (Full High –Definition), 1440, 4k and so on.

The general idea with screen resolution is that the higher is the value, the sharper is the display. With this, you need to get a laptop with a more top screen resolution to immerse in vibrant, brighter displays with more details. Some laptops come with a whopping 4k resolution. However, these laptops come with a premium price tag. Nevertheless, a 1080p screen resolution will suffice for most laptop tasks even the graphics intensive ones.

2. Contrast Ratio

Another aspect you need to look into is the contrast ratio of the display. Contrast ratio is the difference in luminance between the brightest colors against the darkest colors. Displays with a higher contrast ratio typically translate to displays with more accurate color representation.

3. Nits

Brightness is probably one of the essential aspects looked into by consumers across the globe. Just like smartphones and mobile devices, we want our laptop s to provide bright screens that can accurately show the display despite harsh lighting.

Nits are the unit used to measure the degree of brightness from the screen. Generally, a laptop with a higher nit rating means a brighter screen. Most laptops nowadays come with a range of 200 to 300 nits. If a computer exceeds the 300 nits, then this is extremely good compared to the average rating. Macs usually excel when it comes to providing bright displays. Their more recent releases have screens that can reach up to 540 nits.

4. Black and White Accuracy

Another measure of the quality of the screen is how it can show black levels. This aspect is somewhat similar to the contrast ratio. However, this is more concerned about determining how the display can show black colors. This is measured via a number. The lower the number is, the better is the black level representation. This means that the screen can show pitch black colors.

Aside from this, the white levels are also being measured. In contrast, a higher value means a more efficient white color representation. A value of 255 is the maximum level found on the RGB scale. AT this level, the display can show more accurate white colors.

5. Refresh Rates

There are some aspects you need to consider including sRGB graphs, HDR and others. However, we will only emphasize the importance of knowing the screens refresh rates. The refresh rate is the term used to describe the frequency of displays to change the picture. Measured in hertz, the average refresh rates for laptops are 60Hz and 144 Hz. This is extremely important for consumers that are into gaming.

A higher refresh rate translates to better gameplay and lesser crashes. With this, you need not worry about constant lags and delays whenever the video card is pushing its best, especially for graphics-intensive games and tasks.
