The ideal size for a monitor mainly depends on its resolution and how far you’re sitting from the screen.
Overall, most people find that 1920×1080 shouldn’t be used on anything larger than 25-inch; 1440p is ideal for 27-inch, and 4K is great for 27-inch to 43-inch, depending on preference.
Wondering what the perfect monitor size is for gaming?
Well, it all boils down to the screen resolution/monitor size ratio or, more precisely — pixel density, which is measured in pixels per inch (PPI).
While some find 24-inch monitors to be the ideal size, others may think that even a 27-inch display is too small. For most people, 32-inch monitors are too large for gaming. Whatever display size you prefer, you should always keep the screen resolution in mind as well.
Best Monitor Size For 1080p gaming
Nowadays, you shouldn’t get anything smaller than a 24-inch monitor with 1920×1080 resolution; luckily, such monitors are rather affordable.
The Full HD resolution on a 24-inch monitor results in a pixel density of roughly 91 PPI, which is decent when it comes to the image details and screen real estate.
You may be tempted to purchase a 27-inch 1080p monitor since it’s considerably larger and usually only a little bit more expensive than the 24-inch version.
However, a 27-inch monitor is simply too big for 1920×1080 (at least to most users), as you get roughly 81 PPI, which makes the picture somewhat pixelated — text will be smudgy and details blurry.
If you were to sit a bit further away from the monitor, the pixels wouldn’t be as noticeable, which may be acceptable for gaming, that is, until you want to read or type something.
Best Monitor Size for 1440p
The WQHD (2560×1440) resolution is ideal for 27-inch monitors.
You get 108 PPI, which is the sweet spot between picture detail clarity and the available screen real estate as there’s no scaling necessary.
Additionally, 1440p allows for higher refresh rates than 4K — if your PC system can handle it.
There are plenty of 32-inch 1440p monitors available as well. In this case, you get the same picture clarity you would get with 24-inch 1080p monitors, but many find 32-inch monitors too big for gaming as you have to move your head around a lot.
Best Monitor Size for 4K
When it comes to 4K Ultra HD resolution, many will argue that a 27-inch or a 28-inch monitor is large enough. Since the resolution is so high, everything on the monitor will be small, which means you’ll have to scale the interface for text to be readable.
Unfortunately, not all applications scale well, and some don’t scale at all. This affects gaming, as well. If a game doesn’t offer custom scaling, some UI elements may appear tiny.
So, if you’re looking for a 4K monitor for gaming, make sure your favorite games and applications handle scaling well.
Ultrawide monitors feature a 21:9 aspect ratio as opposed to the standard 16:9. The extra horizontal space, along with the usually curved screen, wraps your peripheral vision for a wider field of view and more immersive gaming experience.
The most common screen size of ultra-wide displays is 34-inch, and they can usually be found with either 3440×1440 or 2560×1080 resolution.
The 2560×1080 resolution on a 34-inch monitor offers the same pixel density as 1080p on a 27-inch monitor, so we don’t recommend it unless you will be using the monitor solely for gaming and you sit further away from the screen.
The 3440×1440 resolution on a 34-inch monitor, on the other hand, results in a similar pixel density than that of a 27″ 1440p display, so you’ll get plenty of screen space and sharp details without having to use scaling.
Overall, we recommend the following monitor size/resolution combinations for gaming:
- 23-inch to 25-inch: 1080p
- 27-inch: 1440p or 4K
- 28-inch to 32-inch and over: 4K
- 25-inch to 29-inch ultrawide: 2560×1080
- 34-inch ultrawide: 3440×1440
- 38-inch ultrawide: 3840×1600
- 43-inch super-ultrawide: 3840×1080, 3840×1200
- 49-inch super-ultrawide: 5120×1440
When purchasing a new monitor, you should also ensure you choose the best panel type for you.
