A 168 sq ft room is typical of a primary bedroom or living room. Box sizes vary a lot between products (roughly 15–30 sq ft), so enter your exact box coverage in the calculator above.
The math
12 ft × 14 ft = 168 sq ft
× 1.10 waste = 184.8 sq ft
÷ 20 sq ft/box = 10 boxes (rounded up)
Also plan 168 sq ft of underlayment if your planks don't have it attached, and about 52 linear feet of baseboard or quarter-round for the perimeter (less door openings).
