Hello, I can suggest you to equalize the lengths of the curtain header area and the number of reinforcements on the upper floors with the lower floors. For P3 Curtains, you can get the right and left end area of 52 cm on all floors, and 50 cm for P11 and P12 curtains. It can be done by selecting the "User defined" option in the Accessories tab in the curtain settings.
