Designers recommend marking your ideal TV height with painter’s tape before drilling by sitting in your favorite spot and measuring your eye level, usually forty two to forty eight inches from the floor. Place a horizontal strip of tape at this height on the wall to visualize the TV center line. This non-permanent method allows quick adjustments to find the most comfortable viewing angle without guesswork. You can add vertical tape to simulate screen edges and test placements with natural light or furniture. This hands-on approach simplifies decisions and prevents costly re-mounting, ensuring the TV is mounted with ergonomic precision.
