According to EPA & HUD, what is the recommended size for a paint chip sample?

• A. 1 x 1 inch
• B. 2 x 2 inches (4 square inches)
• C. 3 x 3 inches
• D. 4 x 4 inches

Answer: (B)

A paint chip sample should be large enough to provide sufficient material for accurate laboratory analysis, and EPA & HUD guidelines specify about a 2-by-2 inch piece (roughly 4 square inches) to meet that need. This size gives you material that truly represents the paint film on the wall, not just a tiny fleck, and it provides enough material for initial testing and any required confirmatory tests without needing to take additional samples. Using a chip of this size also helps prevent contamination from surrounding surfaces and makes it more likely the lab can perform reliable analysis, even if multiple tests are needed.
