GoKawiilGuide outlines viewing-distance rules for sizing a TV to your room
A tech guide explains how to pick the right TV size using the industry's 30-degree and 40-degree field-of-view rules, which calculate ideal seating distance based on screen size. It notes a 55-inch TV works best around 7.5 feet away, while a 65-inch set under the more cinematic 40-degree rule suits a closer 6.5-foot distance, and recommends smaller screens for cramped apartments and larger ones for spacious rooms.
