Stop guessing. Plonk shows you exactly which TV size fits your room — at scale, on your wall, before you spend a dollar. Start from a common preset or adjust the diagonal from 20" to 120" and watch a clean TV outline scale to fill the screen, with width and height labeled in inches or centimeters. Aim your camera at a real wall and place a life-size AR outline to see how a 65" or 75" actually looks above the couch. Tell Plonk how far you sit and it tells you the recommended size range — relaxed for living-room viewing or cinematic for an immersive feel. Built for the moment before you buy. No accounts, no ads, no tracking — everything runs on your device. What you get - TV size visualizer with quick presets at 43, 50, 55, 65, 75 and 85 inches, plus +/- adjustment from 20 to 120 inches - Live width and height readouts in inches or centimeters - AR wall placement at true scale using your camera - Drag to reposition along the wall, or use two fingers to pull the TV forward onto a stand - Photo capture so you can compare placements - Viewing distance calculator: enter your seating distance, get the recommended size range, or flip it and check the right distance for a size you already have - Relaxed and cinematic viewing styles, with notes on whether 1080p, 4K or 8K matters at that distance - Multiple aspect ratios: 16:9 plus 21:9, 16:10, 4:3 and 32:9 ultrawide - Universal app for iPhone and iPad Privacy Plonk is fully on-device.
