What are the dimensions of a 3-tab shingle?
In the past, most 3-tab shingles were “Imperial”-sized at 12 inches wide and 36 inches long with an exposure of 5 inches. Now, most 3-tab shingles, typically referred to as “metric” shingles, are larger. Metric shingle exposure is proportional to their larger size, commonly 5 5/8 inches.

What’s the difference between architectural shingles and 3-tab shingles?
3-tab shingles are flat, and they have a single tab shape and size. Architectural shingles are also referred to as dimensional shingles. This is because they provide a more dimensional look to the roof. Each shingle appears more dimensional because it is; multiple layers of materials adhere to the base.
