Small Business Size Regulations (13 CFR Part 121)

The SBA Table of Size Standards matches every six-digit NAICS code to a specific numeric limit [1]. If a business's size does not exceed this limit, it qualifies for small business set-aside contracts, specialized SBA loans, and federal agency preferences. These regulations are codified under 13 CFR Part 121 [2].

Size standards are adjusted periodically to reflect economic inflation. The U.S. government sets these limits using two primary metrics: average annual gross receipts (revenues) and average number of employees [3].
