What size rebar is used in a 6 foot tall block fence?

• A. 2-1/4 inch
• B. 5/8 inch
• C. 1/8 inch
• D. 1/4 inch

Answer: (B)

In reinforced masonry, the wall’s ability to resist bending and cracking comes from using a rebar size that provides sufficient strength without being impractical to place. For a 6-foot tall block fence, the standard choice is 5/8 inch rebar. That diameter, known as No. 5 rebar, offers the right balance of strength and installability, fitting well with typical block cores and grout coverage to keep the wall stable under wind and settlement loads. The other options aren’t suitable: 2-1/4 inch isn’t a standard rebar size and wouldn’t be used in masonry reinforcement, while 1/8 inch and 1/4 inch are far too small to provide meaningful structural support for a fence of this height.
