280 square feet: a 14 × 20 family room
A 14 × 20 room has 280 sq ft and reads as a proper family room or a large primary bedroom with a dressing area. It is also a common size for a one-and-a-half-car garage or a big shed. With a 10 × 14 ft rug centered, 2.0 ft of floor shows along the sides and 3.0 ft at each end, enough for a console table or bookcases beyond the rug.
Order 308 sq ft of flooring (16 boxes), and check that all of it comes from one production run so the color matches across the room. Two coats of wall paint over 493 sq ft use 2.82 gallons, bought as 3 gallons; the ceiling adds 1.60. Poured as a garage or shed pad instead, a 4 in slab with allowance is about 3.8 cubic yards.
