How this is calculated

In metric, the panel is 55.3 cm wide by 31.1 cm tall, or roughly 1723 cm². A 2560 by 1440 panel at this size works out to 117 PPI. Past 74 cm (29 inches)29 inches (74 cm), single pixels stop showing, so the distance you sit at decides whether the grid is visible at all.

Verdict

Pick 25 inches for a single desk screen that needs sharper text than a 24-inch 1080p panel gives, without the footprint of a 27-inch. The panel measures 55.3 cm (21.79 in)21.79 in (55.3 cm) wide by 31.1 cm (12.26 in)12.26 in (31.1 cm) tall for about 1723 cm² (267 in²)267 in² (1723 cm²) of area.

At 1440p, this panel is 8% denser than a 27-inch at the same resolution. The 27-inch gives you about 17% more screen area, and that's the real cost of going smaller.

Desk width is the easy part. Around 100 cm (40 inches) of width leaves room on both sides for speakers or a lamp. The stand's base takes space the panel width doesn't show, so measure it before you buy.
