The Rebar Size Chart provides information on different rebar sizes, including their nominal diameter, diameter in millimeters, area in square inches and millimeters, and weight in pounds per foot and kilograms per meter. This chart is useful for construction professionals and engineers to select the appropriate rebar size for their projects based on the required strength and load-bearing capacity. By referencing this chart, they can determine the most suitable rebar size to ensure the structural integrity and stability of their buildings or infrastructure.


What are the most common sizes of rebars used in construction?

The common sizes of rebars used in construction range from #3 (3/8 inch diameter) to #11 (1 3/8 inch diameter).

What is the purpose of the rebar size chart?

The rebar size chart provides information on the various sizes of rebars available, helping builders and engineers select the appropriate size for different applications and load requirements.

How is rebar size determined?

Rebar size is determined by the diameter of the steel rod. The numbers assigned to rebars, such as #3, #4, etc., indicate the corresponding diameter in eighths of an inch.

Which rebar size should I use for a residential foundation?

For a typical residential foundation, a common rebar size used is #4 (1/2 inch diameter) or #5 (5/8 inch diameter) rebars, depending on the load requirements specified in the construction plan.

What is the weight of different rebar sizes?

The weight of different rebar sizes will vary depending on the diameter. For instance, a #4 rebar typically weighs around 0.668 pounds per foot, while a #8 rebar may weigh approximately 2.670 pounds per foot. The weight can be calculated using standardized formulas or consulting weight tables available for each rebar size.
