Which statement about rebar sizes is correct?

• A. Number 2 rebar is 1/2 inch diameter
• B. Number 3 rebar is 3/8 inch diameter
• C. Number 4 rebar is 3/8 inch diameter
• D. Number 5 rebar is 5/16 inch diameter

Answer: (B)

Rebar sizing follows a simple rule: as the size number goes up, the diameter gets larger. In practice, the common diameters are 1/4", 3/8", 1/2", 5/8", and so on. The diameter 3/8" is the standard match for the size being described, so the statement tying that diameter to the size is correct. The other pairings don’t align with the standard sizing: 1/2" is paired with a larger size than the one referenced, 3/8" is the correct match for the described size, and 5/16" is not a standard diameter paired with that size designation.
