How much slope can you put on a floor without people noticing it. My
guess is about 0.5 % (5mm in a metre).

Does anyone know what is the maximum slope that is not noticable?

thanks,

I have around 10mm over 1.5m between two rooms down a passage past the
stairs. I cannot detect it even knowing it is there.
