For the same exact 39.0 × 56.4 cm canvas, landscape uses 6 sheets with the same margins, overlap and label setting.

How the size is calculated

Printable width is paper width minus the left and right margins. Height uses the top and bottom margins, and excludes the removable 5 mm band if printed labels are enabled.

Finished width = columns × printable width − (columns − 1) × overlap. Height uses the same rule for rows.

Example: four A4 sheets

With 5 mm margins, 10 mm overlap and printed labels off, a 2 × 2 portrait layout covers 39.0 × 56.4 cm. Exact mode keeps the requested canvas and leaves any excess on the last row or column blank.

Can a different orientation save paper?

Try both orientations with the same exact dimensions, margins and overlap. The count depends on those assumptions, rather than always being lower in landscape.
