How many square feet is 18 × 23 ft?

Answer

A rectangle of 18 × 23 ft covers

414 square feet

Any rectangle 18 ft wide and 23 ft long covers 414 square feet. The order of the sides makes no difference — 18 × 23 and 23 × 18 are the same area.

How the Square Footage Is Calculated

Square feet = width (ft) × length (ft)

Area is a product, not a sum: a rectangle holds as many one-foot squares as its width multiplied by its length. Put this rectangle into it:

18 ft × 23 ft

=

18 × 23

=

414 square feet

18 × 23 ft in Other Units

The same rectangle expressed the other common ways. The perimeter is the figure to use for skirting, edging or fencing — and it is what tells this rectangle apart from other sizes with the same area.

Square feet	414 square feet
Square meters	38.46 m²
Square yards	46 yd²
Perimeter	82 ft

Note: this is floor area. Wall area is height × length for each wall, and a room that is not a plain rectangle has to be split into rectangles first and added up.
