Use this 27 inch monitor dimensions calculator to find the approximate width, height, diagonal, and desk space for a standard 16:9 monitor. The listed monitor size is the diagonal screen measurement, not the full outside product size. The bezel, stand, arm mount, and cable clearance can add extra width, height, and depth depending on the model.

How Wide Is a 27 Inch Monitor?
A 27 inch monitor with a 16:9 aspect ratio is about 23.5 inches wide, or 59.8 cm wide. This is the screen width only. When checking whether it fits your desk, monitor arm, or workstation, leave room for the bezel and side clearance.
How Tall Is a 27 Inch Monitor?
The screen height of a 27 inch monitor is about 13.2 inches, or 33.6 cm. The full height can be larger when the monitor is placed on its stand.
27 Inch Monitor Viewing Distance
A practical viewing distance for a 27 inch monitor is roughly 2.3 to 3.6 feet. For monitors, the best distance also depends on text size, resolution, desk depth, and whether you use the display for work, gaming, or editing.
How the Size Is Calculated
This page uses a 16:9 standard widescreen aspect ratio. To calculate width and height from the diagonal, the calculator splits the diagonal across 16 units of width and 9 units of height.
width = diagonal x 16 / sqrt(16^2 + 9^2) height = diagonal x 9 / sqrt(16^2 + 9^2) Will a 27 Inch Monitor Fit?
Compare the screen width of 23.5 inches with the available space on your desk, monitor arm, or multi-monitor setup. The actual body can be slightly wider than the screen, so checking the manufacturer dimensions is still important before buying or mounting.
If you are comparing nearby sizes, check 24 inch monitor dimensions and 32 inch monitor dimensions to see how much width and height change from one screen size to the next.
Screen Area
The viewable area of a 27 inch monitor is about 312 square inches, or 2,010 square centimeters. Screen area grows quickly as diagonal size increases, so a larger display can feel much bigger than the diagonal number alone suggests.
Desk Space Notes
For a monitor, width is usually the most important fit measurement. Leave extra room for the stand base, monitor arm movement, speakers, laptop placement, and any second display you plan to use.
Ultrawide monitors can replace a dual-monitor setup for many workflows, but they need more horizontal desk space. A 16:9 display also feels different from a standard 16:9 monitor because it is wider for the same diagonal size.
