How Big is a 27-Inch Monitor? (Width, Height, Resolution)

How big is a 27-inch monitor? Is it big enough to work, play games, & stream videos? If yes, can it fit comfortably on your desk? In the past, buying 20-inch monitors (or smaller ones) was the norm. But, today, monitor costs have gone down considerably. So opting for the 27-inch monitor size makes total sense unless you’re extremely constrained for space. 

A high-quality 27-inch monitor won’t cost you more than $150. But, exactly how wide & how tall is a 27-inch monitor? Also, what is the benefit of buying a 27-inch monitor over a less-priced monitor that’s under 22 inches? Plus, how long is a 27-inch monitor & can it fit on my desk? 

The Internet is full of such questions from PC owners who want to buy a monitor that will serve them well for a long time. I’m here to answer these questions and clarify all of your doubts about 27-inch screen dimensions. First, let’s find out how big a 27-inch monitor actually is.

Why is Monitor Size Important?

Let’s say you buy a basic, low-cost 17-inch monitor. The highest resolution on such small monitors is 1,280 x 1,024. That means a 17-inch monitor can display 1,310,720 pixels at once. Now, let’s say your friend opts for the 27-inch monitor size. A standard 27-inch monitor will have a resolution of 2560 × 1440. That means a 27-inch monitor can display a total of 3,686,400 pixels at once. 

Your friend’s 27-inch monitor can display three times as much information (pixels) as your basic 17-inch monitor. But, the largest pixel count a TV can display simultaneously doesn’t determine the overall image quality. We’ll have to consider the monitor’s pixel density to determine image quality. 

A monitor’s pixel density refers to the number of pixels per inch on display. It’s basically the ratio between a monitor’s size and its resolution. A metric called “PPI” or “pixels per inch” denotes a monitor’s pixel density. 

Typically, the higher a monitor’s pixel density, the sharper the picture quality. Since smaller monitors have more densely-packed pixel densities, they have sharper images & smoother lines. But that DOES NOT mean the higher the pixel density, the better the image quality. 

In general, a monitor with high pixel density will deliver sharper images – but only up to a point. Then, as PPI becomes higher & higher, the benefits of having high pixel density start diminishing. It eventually leads to a point where the PPI makes no considerable difference in image quality. 

So, what’s a good PPI? For the best viewing experiences, you’ll need a pixel density monitor between 90 and 160 PPI. At this PPI, you’ll get super-sharp details. On the other hand, anything below 90 PPI is too low for gaming, video content consumption, & especially for work where users need loads of screen space. 

So, what’s the PPI of a 27-inch monitor? It depends on the screen resolution. 

Here’s a helpful chart for you to figure out how PPIs vary depending on screen size & resolution:

How Big is a 27-Inch Monitor?

Physical Dimensions

  • The average 27-inch monitor width is 24 inches (wide). 
  • The average 27-inch monitor height is 17 inches (high).

Most new-age monitors have similar dimensions. However, their thicknesses tend to vary a lot. For instance, curved displays are often marketed as 27-inch monitors. But, they have much bigger dimensions than flat panels. curved displays also tend to be less thick than their flat-panel counterparts. Until you physically determine a 27-inch monitor’s actual height, width, & thickness, it’s hard to say exactly how big they are.

To get a basic 27-inch monitor size reference, we noted down the widths, heights, & thicknesses of the most popular 27-inch monitors in the market. Here’s what we found:


  KOORUI 27-Inch QHD Curved VA Computer-Monitor

  •  27.83-inches
  •  18.23-inches
  •  5.71-inches

  GTEK Curved Frameless FHD Gaming Monitor

  •  24-inches
  •  17-inches
  •  1.0-inches

  LG 27MP400-B 27” Full HD

  •  24.1-inches
  •  17.9-inches
  •  7.5-inches


  •  24.11-inches
  •  21.22-inches
  •  9.37-inches

Typical Aspect Ratio of a 27-Inch Monitor 

  • Most 27-inch monitors have 32:9 aspect resolutions; this means they’re wide, not-so-tall screens. 

Resolution of a 27-Inch Monitor 

There’s no standard resolution for 27-inch monitors. Resolutions of these monitors can range from 1920 × 1080 to 3840 × 2160. As per my experience, a 27-inch monitor with 2560 × 1440 resolution offers the best viewing experience. In addition, this monitor has a PPI of 109 which is perfect for work, gaming & HD content streaming. 

27-Inch Monitor Size Reference

Are all 27-inch monitors the same size? Unfortunately, no. The sizes of 27-inch monitors vary from brand to brand. Typically, the size of the bezel plays a key role in determining 27-inch screen dimensions. The bigger the bezel size, the higher the screen dimensions. 

27-Inch Monitor Dimensions in CM

Here are the 27-inch monitor dimensions in cm & mm:

  • 60.96 cm x 43.18 cm (width x height)
  • 610 mm x 43 mm (width x height)

27-Inch Monitor vs. other Monitor Sizes 

The main metric I use to judge different monitor sizes is speed, i.e., how quickly the monitor responds to inputs. Typically, monitors under 24 inches aren’t very fast & they experience high amounts of input lag. On the contrary, the average 27-inch monitor will have a much higher refresh rate. It will respond considerably quicker than its smaller counterparts.

Another perk of buying a 27-inch monitor is the cost. 29 & 32-inch monitors cost way more than their 27-inch counterparts. Being a smart buyer, I was naturally drawn toward 27-inch monitors. If you’re still unsure if this monitor size is right for you, check out this video:

Notice how 24, 27, & 32-inch monitors look when placed next to each other. In addition to looking better, 27-inch monitors are also better for gaming and productivity.
