Common ratios

• 16:9 — TV, most monitors, all streaming. Baseline.
• 16:10 — laptops (especially MacBooks, Surface). Modestly more vertical space.
• 3:2 — Surface, some Chromebooks. Document-friendly.
• 21:9 (2560×1080, 3440×1440, 5120×2160) — ultrawide. Cinematic, productivity-friendly.
• 32:9 — two 16:9 panels stitched. Sim-racing and ultra-wide productivity.

Content tradeoff

21:9 movies fill an ultrawide perfectly; 16:9 TV content shows pillarboxing. Most modern games render natively at ultrawide; older games and most console titles do not.
