What size TV stand do I need for a 65- or 75-inch TV?

Specialist-community consensus on r/4kTV and r/hometheater is that the stand should be at least as wide as the TV's footplate and ideally close to the full screen width — typically 58 inches or wider for a 65-inch TV and 66 inches or wider for a 75-inch TV. Going narrower than the TV's feet is the most common regret reviewers cite.
