How many shingles in a bundle?
Quick Answer
A standard bundle of 3-tab asphalt shingles contains 26 shingles and covers approximately 33 square feet (one-third of a roofing square). Architectural (dimensional) shingles vary by brand: most contain 21–29 shingles per bundle, also covering 33 sq ft. You need 3 bundles to cover one roofing square (100 sq ft).

How to Calculate It Yourself
- 1
One roofing square = 100 sq ft of roof surface.
- 2
One bundle covers 33 sq ft = one-third of a square.
- 3
So 3 bundles = 1 square. To find bundles needed: calculate roof squares × 3.
- 4
Add 10% waste: squares × 1.10 × 3 = bundles to order. For a 20-square roof: 20 × 1.10 × 3 = 66 bundles.
Pro Tip
Ridge cap shingles are sold separately — don't count on cutting field shingles for the ridge. One bundle of ridge cap covers about 35 linear feet. Measure your ridge(s) and order accordingly.
