Side-by-side specifications, then the same wall built from each tile, so the comparison is in panels, kilograms, circuits and data runs rather than in marketing copy.

Whole cabinets rarely hit an identical size, so each wall is the closest build to a real video format (16:9 or 16:10) near 8 m wide for that tile: 8.00 × 5.00 m and 8.00 × 5.00 m respectively.
Comparing something else, or your own OEM tile? The comparison tool takes any panels, up to four at once, at your wall size. Add your own spec once in the calculator and it appears there alongside the catalogue.
