There are approximately 33.33 square feet in a bundle of standard composite shingles. A square is a 10-foot by 10-foot area and requires three bundles of shingles for coverage.
2 feet x 50 feet = 100 square feet or 1 roofing square. 50 feet x 50 feet = 2500 square feet, so 2500 / 100 = 25 roofing squares. Most composition shingles are 3 bundles per square. Most of the 40yr composition shingles are 4 bundles per square (Some 5 or more).
