Monitor size guide
27 Inch Monitor Dimensions: Width, Height and PPI
Monitor shopping often mixes physical size and resolution. This guide separates the 27 inch screen footprint from its pixel density.
Quick answer
A 27 inch 16:9 monitor has a visible screen about 23.53 inches wide and 13.24 inches tall, or about 59.8 x 33.6 cm.
Size and resolution are different decisions
The 27 inch number describes the diagonal of the visible panel. It does not tell you how many pixels the monitor has or how sharp text will look.
At 1920 x 1080, a 27 inch monitor is about 81.59 PPI. At 2560 x 1440, it is about 108.79 PPI. At 3840 x 2160, it is about 163.18 PPI.
Desk planning
The visible screen width is about 23.53 inches, but the product width may be larger. Dual 27 inch monitors usually need more than 48 inches of desk width after bezels and monitor arms are included.
If you sit close to the screen, resolution and scaling matter as much as physical width.
