Hi,
I need you help to understand how scale works with geographic coordinate
systems.
For projected coordinates systems, the layouts seems to work as expected.
This is my use case:
I've draw a polygon with 1000m width and height, and another with 1500,
width and height, sharing the upper left corner.
1) Using a projected CRS, if I create a layout with a 150mm x 150mm map,
the 1500m polygon fits perfectly on the print area, setting a 1:10000
scale. That's what I expected. The results is

2) Using a geographic CRS, the same 150mm x 150mm map, at the same
1:10000 scale, the area is bigger then the 1500m polygon. The result is
attached https://nextcloud.geomaster.pt/index.php/s/H2eAytsPANyxn6Y
On both layouts the scale bar widget is working properly. The distances
(and areas) are properly calculated in QGIS interface. I have set the
GRS 1980 ellipsoid for distance and area calculations.
My question is: why the second layout does not fit the 1500m polygon
properly? The second layout shows approximately a 2000m square, instead
of a 1500m square.
Regards,
Jorge Gustavo
