Understanding Rebar Sizes

Rebar (reinforcing bar) sizes are standardized to ensure consistency in construction. In the United States, rebar is specified in imperial sizes, where the number corresponds to the diameter in eighths of an inch. For example, a #4 rebar is 4/8 or 1/2 inch in diameter. This calculator uses standard weight-per-length data for different rebar sizes to provide a quick weight estimate, which is useful for shipping and structural calculations.
