11x11 in square feet, square yards and square meters
A square bedroom is about this size. The area is length times width: 11 × 11 = 121 sq ft. Measure to the walls at the longest point, and add closets and alcoves you will floor.

An 11 × 11 room: a square with a little breathing space
Eleven feet each way gives 121 sq ft, noticeably more usable than a 10 × 10 because the extra foot lands on both axes. A bed can sit centered on any wall and still leave a path on three sides. An 8 × 8 ft rug shows 1.5 ft of floor on every edge. The diagonal is 15.6 ft.
Odd dimensions cost a little more in scrap: 12 in tiles have to be cut along two walls, and you would want 134 of them with the usual tenth extra. Plank flooring comes to 133 sq ft, which rounds up to 7 boxes. For paint, 44 ft of wall at 8 ft is 352 sq ft, or 301 after one door and two windows, and two coats need 1.72 gallons. Buy 1 gallon + 3 quarts and keep what is left for touch-ups.
