A 100 sq ft floor with 4×4" square tiles (straight layout, 10% waste) requires roughly 991 tiles — about 11 boxes at 11 sq ft per box. You'll need approximately 4 lbs of sanded grout for a standard 1/8" joint. Switch to diagonal or herringbone below to recalculate with the higher waste factor those patterns demand.
