What scaling should I use with a 27-inch 4K monitor?

TechCompare recommends 200% scaling (200% exact).

Our recommendation for a 27-inch (68.6 cm) 4K monitor is 200% scaling, with an exact target of 200%. The panel has twice the pixel density of our same-size 1080p reference. Doubling the interface scale therefore keeps modeled buttons and text at the reference's physical size. You still use the full 3840 × 2160 panel resolution. The desktop just allocates more pixels to each interface element.

How this is calculated

The monitor's density is about 163.18 PPI. At 200%, its logical desktop is 1920 × 1080, and the Windows preview leaves 1920 × 1032 for windows after the taskbar. At 175%, the desktop grows to about 2194 × 1234, while 150% gives 2560 × 1440. Those lower settings fit more content because controls take up less physical space. A 1920 × 1080 logical desktop doesn't mean the display has become a 1080p panel or that every app renders identically.

Verdict

200% is a useful starting point if comfortable interface size is your priority. Compare 175% when you want more room for an editor, spreadsheet, or two windows. Choose 150% if the smaller text still works for you at your viewing distance. The preview shows the size and space tradeoff, but it can't reproduce your app's exact font rendering. Try the setting on the real display before deciding which amount of workspace feels right.

Frequently asked questions

What scaling should I use with a 27-inch 4K monitor?
TechCompare recommends starting at 200%. The exact target is 200%, based on our 27-inch (68.6 cm) 1080p reference at 100%. It's a size preference, so compare nearby settings and choose the one that feels comfortable on your own display.
Is this the same as Windows' recommended scaling?
No. TechCompare uses its own preferred physical interface size, based on a 27-inch (68.6 cm) 1080p monitor at 100%. We calculate its full pixel density and match other displays to that reference. This tool doesn't detect the setting Windows marks as Recommended. Comfort, eyesight, viewing distance, and your apps can make a different percentage suit you better.
Does scaling change my monitor's resolution or PPI?
Scaling changes how many panel pixels a logical interface unit occupies. It doesn't change the panel's physical pixel density. A 3840 × 2160 display at 200% has a modeled 1920 × 1080 logical desktop while still using the 4K panel. Keep the display at its native resolution when comparing scaling. Microsoft explains resolution and scaling settings.
How do I change display scaling in Windows 11?
Open Settings > System > Display, select the monitor you want to change, then choose a percentage under Scale in the Scale & layout section. Try your preferred setting in a few everyday apps. This preview is a planning aid and won't apply anything to Windows. See Microsoft's display settings guide for the current steps.
Does Ubuntu GNOME support every percentage in the preview?
The dropdown models interface sizes from 100% to 500%. It doesn't check which settings your Ubuntu version, desktop session, or graphics setup offers. The Ubuntu top panel and Dock use illustrative dimensions. Choose the scale that's actually available in your display settings, then use the preview to understand the size and workspace tradeoff.
Is the desktop preview life-size or pixel-perfect?
No. It shrinks to fit the page while preserving panel proportions and modeled interface sizes. Example windows, icons, and fonts are illustrations. The Windows taskbar uses a 48-unit reference measured on one desktop, while the Ubuntu panel and Dock use sizing assumptions. Compare relative layout space here, then judge actual text and app rendering on your own monitor.
