When you need to repair or replace the screen on your laptop or purchase a case for it, you are asked what size the screen is. You may not have the dimensions remembered, and you may be without a ruler or measuring apparatus.

Computer monitors are measured in a variety of ways. Thus, the dimension is determined by the requirement. Confirm the particular proportions you require in terms of body size, pixels per square inch. To physically measure the screen, keep the plastic bezel around the screen out of the measurement and simply measure the screen area.

Laptop model numbers typically begin with one or two letters preceding the number one. The number following the first few letters often denotes the display’s size.

2) Using the Model Specifications for Your Laptop

A simple technique to determine the screen size of your laptop without measuring it is to review the specifications of your laptop model. These specifications will be printed on the casing you purchased, and may be accessed via the user manual or the cover at the bottom of your laptop. Check to see if they exist. Specifications Indicate the screen size or, at the very least, the model number.

If you are unable to access the laptop’s packaging or server-derived functions, a simple search for model information should be performed in your computer’s settings. Typically, the screen size may be found under Laptop Features in the Display Settings folder. If that does not work, navigate to the Advanced Display Settings tab. If you are unsure of what they signify, proceed with caution when adjusting them.

In some circumstances, the search may be based on model characteristics rather than screen size. Utilize this model number to conduct an internet search for the screen size that corresponds to your device. If this is usual, the information may not be entirely correct. There will be a dedicated webpage for each one you establish, and you can inquire about the measurements with their customer support.

Step 1: Navigate to the “Settings” menu in Windows. And then click on the first “System” icon.
Step 2: After clicking “System,” a box similar to the one below will popup; you must click on “Advanced display settings.”
Step 3: When you click “Advanced display settings,” you’ll see a summary of your screen’s configuration.

3) Download a Program or Conduct an Online Check

The majority of PC applications provides information about your laptop. Occasionally, specify the screen size in addition to other display parameters. Another quick way to determine the display’s status is to check it online. Infoblip has a simple-to-use display size detector.

Once you’ve located this information, type it into Google, the manufacturer’s website, or the retailer where you purchased the laptop. You can then click on the best-matching results. The result will then include the display specifications and other relevant hardware details for the laptop.

5) Consult the laptop’s manual

To verify the correct size, use a tape measure and consult your laptop’s handbook for the screen requirements. The documentation specifies the suitable screen size for the laptop.

6) Examining the Laptop’s Backside

Rotate the laptop’s back and check for labels displaying laptop models and some of the laptop’s best characteristics. Additionally, it includes the display’s size.

Additionally, the screen size of some laptops is displayed by a number in the upper right corner. For instance, the H243HX indicates a screen size of 24 inches.

Additional Considerations

Along with the screen size, there are a few more factors to consider.

Resolution of the display

The phrase “screen resolution” refers to the number of pixels in a display area. The majority of laptops have a 1920 x 1080 resolution, while the more affordable models have a 1024 x 720 screen. To make the phrase more natural and intelligible, most manufacturers abbreviated it as FHD (Full High Definition), 1440, or 4K.

The main concept behind screen resolution is that the higher the price, the faster the display. It requires a laptop with a high top screen resolution in order to fully immerse yourself in the lively, brilliant display with increased detail.

Certain laptops feature a native 4K resolution. However, these computers are not inexpensive. However, even if the visuals are powerful, a 1080p screen resolution will enough for the majority of laptop work.

Ratio of Contrasts

Another thing to consider is the aspect ratio of the display. In comparison, there is a difference in brightness between bright and dark hues. Higher contrast ratio displays typically produce more realistic color representations.


Perhaps one of the most critical features in the eyes of the world’s customers is brightness. As with smartphones and other mobile devices, we want our laptops to have bright screens capable of displaying the display accurately even in bright light.

Nit is a unit of measurement for the brightness of a display. By and large, a laptop with a high night rating suggests that the screen is bright. Nowadays, the majority of laptops have a brightness of between 200 and 300 nits. If the computer’s brightness is greater than 300 nits, it is significantly brighter than the average rating. Macs are typically superior in terms of producing brilliant displays. Their most recent iteration features screens with a maximum brightness of 540 nits.

Accuracy in black and white

Another criterion for screen quality is the panel’s ability to display a black surface. This is comparable to the contrasting ratio. However, it is mainly concerned with determining how dark may be displayed on the display. It is quantified by a number. The fewer the number, the better. The more accurate the representation of the black surface, the more the screen can display a black hue on the pitch.

Additionally, white levels are being monitored. A greater value, on the other hand, indicates a more efficient representation of white. 255 is the maximum value on the RGB scale. The display can now display a more accurate white hue at this setting.

Rates of Refreshment

Several factors must be considered, including the SRGB graph, HDR, and others. However, we shall underline the critical nature of understanding the refresh rates of the panels. The word “refresh rate” refers to the frequency with which the display changes the image. The average update rate for laptops is between 60 and 144 Hz, measured in Hz. This is critical for gamers.

Increased refresh rate results in improved gameplay and fewer crashes. It eliminates the need for repeated breaks and delays when the video card is operating well, which is especially important for graphics-intensive games and tasks.
