This page puts the two sheets side by side, then builds the same wall from each tile, so the comparison is in panels, kilograms, circuits and data runs.

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: 7.68 × 4.32 m and 8.00 × 4.50 m respectively.
For other panels, 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.
