    hi all trying to work out falls and depths for my patio, from my limited knowledge i understand if i have a gradient on my spirit level so that the bubble slightly passes the lines either side, this should be a sufficient fall, i would like to know what fall does this actually convert to i.e 1 in 100, 1 in 60 etc.

    Find a straight and level surface, lift one end of your spirit level until the bubble hits the line and measure the distance the end of the level is from the ground.
    Divide this distance by the length of your level (in the same units) and you have your fall.
    If there was a standard for these lines, it is probably worth doing this anyway. Many cheap levels I have had, strongly disagree with each other :)

    Levels vary. Plenty of mobile phone apps to give you the fall . You can use a line set to fall you require for level.

    It doesn't matter, you don't lay a patio to fall by levelling individual slabs with a spirit level. You lay them to a line with the fall set using a spirit level set level on a straight edge and a tape measure to measure down.
