How to Measure Monitor Size?

Measure Monitor Size

To accurately determine your monitor’s size, you will need a tape measure or ruler. Monitor size is measured diagonally from one corner to the opposite corner of the screen. This measurement is expressed in inches and is known as the screen’s diagonal measurement.

To measure the size of your monitor, follow these steps

  1. Find the two corners of your screen that are opposite each other.
  2. Place the end of your ruler or measuring tape on one corner of the screen.
  3. Stretch the measuring tape or ruler diagonally across the screen to the opposite corner.
  4. Take note of the measurement in inches.

It is important to measure the screen diagonally because this is the standard measurement for computer monitors. Measuring the screen’s height or width alone will not accurately represent the monitor’s dimensions.

Factors to Consider Before Buying a Computer Monitor 

3440x1440 vs 4k

There are several factors to consider before buying a computer monitor. These factors can affect your viewing experience and your computer’s overall performance. Here are some of the key factors to consider.


The number of pixels on the screen, typically expressed in width and height. The image will be clearer and more detailed if the resolution is higher. 1080p (Full HD), 1440p (Quad HD), and 2160p (4K Ultra HD) are all common resolutions.

Response Time

Response time refers to how quickly a monitor can change from one color to another. A quicker response time can reduce motion blur and make a display more responsive. The optimal response time for gaming or fast-paced content is typically 1 millisecond or less. 

Refresh Rate

A monitor’s refresh rate is how many times per second the screen is updated. A higher refresh rate can make the motion on the screen look more fluid and smooth. Most monitors have a refresh rate of 60Hz, but some can go up to 120Hz or even higher. A higher refresh rate is especially important for games and other fast-paced content.

Size and Aspect Ratio

A monitor’s size and aspect ratio can affect your viewing experience and desk space requirements. Monitor sizes typically range from 19 to 40 inches, and aspect ratios can range from 4:3 to widescreen 16:9 to ultrawide 21:9. 


Ensure that the monitor you select has the required ports for your computer and other devices, such as HDMI, DisplayPort, and USB-C. Some monitors include USB hubs or other features that facilitate the connection of peripherals.


Monitors vary greatly in price, so consider your budget as well as the features that are most important to you. Remember that higher-end monitors with advanced features like HDR or G-Sync may cost more than budget models.
