Thin-Set Mortar Coverage
The bags of thin-set a tile job needs, sized off the trowel notch the way a setter buys it -- a 1/4 in notch covers about twice the area of a 1/2 in notch. tile-count gives the tile and grout.
Formula and source
Coverage per bag from the square-notch trowel (~95 / 63 / 45 sq ft for 1/4 / 1/4x3/8 / 1/2 in); bags = ceil(area x (1 + waste) / coverage).
Manufacturer thin-set coverage charts (Custom Building Products / Mapei / Laticrete, by name); ANSI A108 mortar-contact minimum.
