Methodology and sources
Nothing on this site is estimated by hand. The arithmetic is in /js/fit.js, which runs in your browser and at build time, and the data files are public at /data/tvs.json and /data/standards.json.
TV mount patterns and weights
Each model's VESA hole pattern and weight without stand were read from the manufacturer's own US product page on the check date (LG, Samsung, Sony, TCL). Where the page lists no pattern, the model shows that instead of a guess. Wall-mount screw sizes are not listed per model because manufacturers publish them inconsistently; check the TV's manual. Checked 2026-10-20.
- LG: https://www.lg.com/us/tvs — 48 models
- Samsung: https://www.samsung.com/us/tvs/all-tvs/ — 78 models
- Sony: https://electronics.sony.com/tv-video/televisions/c/all-tvs — 46 models
- TCL: https://us.tcl.com/collections/smart-tv — 15 models
Of 187 models, 174 have a published pattern. The rest are listed with what the maker says instead. Left out: TCL QM9K (65, 75, 85, 98-inch) — TCL's QM9K product pages show a spec table identical to the QM8K's to two decimal places at every size, so the QM9K's own figures could not be confirmed. It will be added when TCL's page shows distinct figures. One model lists two patterns (LG's 115-inch QNED92B: 1000 x 700 and 1000 x 500); both are shown.
Viewing distance
Viewing distances are geometry from published viewing angles: a 16:9 screen's width is 0.8716 x its diagonal, and the distance at which it fills a horizontal angle A is width / (2 x tan(A/2)). Resolution distances use the 20/20 acuity limit of one arcminute per pixel. The same formulas reproduce the reference figures quoted in the source (30 degrees = 1.6264 x diagonal; 31.2 degrees for 1080p; 58.37 degrees for 4K).
- SMPTE 30° (mixed viewing): The widely quoted figure for everyday TV watching: the screen fills a 30° field of view. Source: Wikipedia, Optimum HDTV viewing distance (SMPTE section, citing a Fujitsu white paper and trade publications). "Viewing an HDTV from a position where the display occupies a 30-degree field of view is widely quoted as the SMPTE recommendation; the article notes there seems to be no direct recommendation from SMPTE itself."
- THX 40° (cinema): THX's home-theater figure: a wider 40° view for film, about 1.2 x the diagonal. Source: Wikipedia, Optimum HDTV viewing distance (citing THX Home Theater Display Setup). "THX: the best seat-to-screen distance is one where the view angle approximates 40 degrees; divide the diagonal by .84 to calculate the optimum viewing distance."
- Resolution limit: one arcminute per pixel (20/20 vision). Source: Wikipedia, Optimum HDTV viewing distance (citing Sugawara et al., Future Prospects of HDTV, and Webvision on 20/20 acuity). "A viewer would need a view angle of about 31.2 degrees or greater to resolve all detail on a 1080p display, and about 58.37 degrees or greater for 2160p (4K)."
Formulas, for a screen of diagonal D inches with 16:9 aspect: width W = 0.8716 D; distance at angle A = W / (2 tan(A/2)); farthest distance at which a screen with P horizontal pixels is fully resolved = W / (P tan(1/60°)). With these, 30° gives 1.6264 D, 40° gives 1.197 D, and the acuity distances correspond to view angles of 31.2° (1080p) and 58.37° (4K) — the figures in the source.
VESA standard
Pattern parts, screw sizes and the screw-depth rule come from Wikipedia, Flat Display Mounting Interface (VESA MIS / FDMI).
- Parts B to E use M4 machine screws; Part F uses M6 or M8.
- Part F's table lists square patterns of 200, 300, 400, 500, 600, 700, 800, 900 and 1000 mm.
- The article's example: a 30-inch TV weighing more than 50 lb (23 kg) would need a Part F mount.
- Screw length is the bracket thickness plus the depth the standard allows; for Part F, M6 screws must engage at least 9 mm and at most 10 mm, in a hole no deeper than 12 mm.
Mount types
From SANUS, The ultimate guide to picking and installing a TV mount:
- Fixed: Holds the TV flat to the wall. No tilt or swivel. SANUS: "Attaches securely to wall to prevent TV tip-overs."
- Tilting: Tilts to cut glare and to angle down when the TV sits above eye level. SANUS: "Tilts to reduce glare from lights and windows."
- Full-motion: Extends, swivels and tilts, for corners, recesses and wide rooms. SANUS: "Extends to allow mounting in corners and recesses. Swivels left and right for the perfect view from anywhere."
What the site does not do
It does not list per-model screw sizes, because makers publish them inconsistently and some pages mix wall-mount and stand screws; it does not estimate TV body dimensions from screen size; and it does not give mounting heights, which depend on your seating. The manual for your TV and mount is the final word. Data version 2026-10-20.
