Desktop computer monitors are available in a range of sizes, from as small as 13 inches to as big as 50 inches or more if you use a TV as a monitor. Laptop screens generally range from 11.6 to 17 inches. While technology plays a role, generally speaking, the larger the monitor size, the higher the cost. Laptops are a bit different as features and portability weigh more heavily as far as price is concerned. For both desktops and laptops, the size of the monitor or screen is the distance from the top left corner to the bottom right corner, in inches.

Desktop computer monitor - measure screen

The size of a desktop computer monitor can be determined by physically measuring the screen. Using a measuring tape, measure the size of the screen from the top left corner down to the bottom right corner. Measure only the screen and do not include the bezel (the plastic edge) around the screen.

Desktop computer monitor - model number

The model number of the monitor usually includes the size of the monitor within it. For example, an Acer 20-inch screen could have a model number of S201HL. The "20" after the "S" is the size of the monitor, in this case, 20 inches. In general, a model number will start with one or two letters followed by numbers. The first two numbers after the letters usually represent the size of the monitor.

Laptop screen - measure screen

The size of a laptop screen can be determined by physically measuring the screen. Using a measuring tape, measure the size of the screen from the top left corner down to the bottom right corner. Measure only the screen and do not include the bezel (the plastic edge) around the screen.

Laptop screen - review specifications

The specifications for a laptop will include the size of the laptop screen. Check the laptop's specifications for a section labeled "Screen" or similar. The screen size will be listed in that section, in inches.
