How this is calculated

In metric, 62.0 cm wide by 34.9 cm tall, or roughly 2161 cm². That's about 8% more area than a 27-inch. Past 55 cm (22 inches)22 inches (55 cm), single pixels stop showing. Sit closer than that and the grid shows through the letters.

Verdict

Choose 28 inches when 4K text matters more than a big canvas. The panel measures 62.0 cm (24.40 in)24.40 in (62.0 cm) wide by 34.9 cm (13.73 in)13.73 in (34.9 cm) tall for about 2161 cm² (335 in²)335 in² (2161 cm²) of area.

Set beside a 32-inch 4K panel, the 28-inch packs 14% more pixels per inch. The 32 spreads the same pixel count across a bigger area.

The cost is scaling. At 150% scaling, 4K gives you the desktop of a 2560 by 1440 screen, so the extra sharpness comes with less room than the pixel count suggests. A desk about 100 cm (40 inches) wide holds one panel with room to spare.

Frequently asked questions

What are the exact dimensions of a 28-inch 16:9 monitor?
A 28-inch 16:9 screen is 62.0 cm (24.40 inches)24.40 inches (62.0 cm) wide and 34.9 cm (13.73 inches)13.73 inches (34.9 cm) tall, with about 2161 cm² (335 square inches)335 square inches (2161 cm²) of screen area. The frame and stand sit outside those figures.
Is a 28-inch 4K screen too small for coding?
Not if you scale the text to a size you can read. The sharper letters help over long sessions, and your scaling setting sets how much code fits on screen.
What desk width fits two 28-inch monitors?
Two 28-inch 16:9 panels side by side span 49 inches. A 60-inch (152 cm) desk gives them room, and monitor arms free the surface underneath.
What's the PPI of a 28-inch 4K screen?
About 157 PPI. That's the raw sharpness, before scaling changes how big the text looks.
