Width affects how much desk space you need, while the height delta shows how much vertical space changes for documents, timelines, and video.
The practical choice depends on what feels limiting in your current setup. For laptop-plus-monitor planning and travel setups, the wider option gives more room for side-by-side windows, while the taller option keeps more vertical content visible without pushing the edges of the screen as far away. If your desk is shallow, width and viewing distance matter as much as raw diagonal size.

For text-heavy work, PPI is the number that decides whether you are buying more room or just making everything bigger. A lower-PPI large screen can feel spacious for windows but softer for code and documents. A higher-PPI screen may need OS scaling, but it usually gives cleaner text and more flexible sizing.
