How Many Shingles Calculator — Get Your Count in Seconds
A how many shingles calculator converts your roof dimensions into two numbers you need for ordering: bundles and individual shingles. While bundles are what you buy at the store, knowing the individual shingle count helps you plan for repairs, verify coverage, and communicate with contractors.

Frequently Asked Questions
How many shingles do I need for a 10×10 area?
A 10×10 area = 100 sq ft = 1 roofing square = 3 bundles = ~63 architectural shingles or ~78 3-tab shingles (before waste).
Why do architectural shingles have fewer per bundle?
Architectural shingles are thicker and heavier than 3-tab shingles. Each individual shingle covers more area due to the laminated design, so fewer are needed per bundle while still covering 33.3 sq ft. Read our full guide on how many roof shingles per bundle.
