Reinforcing bars, also known as rebar, are steel bars that are commonly used in construction projects to provide tensile strength and reinforcement to concrete structures. In Europe, rebar sizes and standards are governed by the European Standard EN 10025 and EN 10080.

European rebar sizes are designated by the letter ‘D’, followed by a number which represents the nominal diameter of the bar in millimeters. For example, a D10 rebar has a nominal diameter of 10 millimeters. The most commonly used European rebar sizes are D8, D10, D12, D16, D20, D25, D32, and D40.

Rebar sizes in Europe do not follow a consistent pattern like other countries such as the United States, where rebar sizes increase in increments of 1/8 inch. Instead, European rebar sizes are based on the metric system, making them more precise and standardized.

The following chart shows the nominal and actual diameter, cross-sectional area, and weight of European rebar sizes:

Rebar Size | Nominal Diameter (mm) | Actual Diameter (mm) | Cross-sectional Area (mm2) | Weight per Meter (kg/m)

D8 | 8 | 7.9 | 49.9 | 0.395

D10 | 10 | 9.9 | 78.5 | 0.617

D12 | 12 | 11.9 | 113.1 | 0.888

D16 | 16 | 15.9 | 201.1 | 1.58

D20 | 20 | 19.9 | 314.2 | 2.47

D25 | 25 | 24.9 | 490.9 | 3.85

D32 | 32 | 31.9 | 804.2 | 6.31

D40 | 40 | 39.9 | 1256.6 | 9.86

In Europe, rebar sizes can also be denoted using the letter ‘B’ followed by a number, representing the bar’s nominal weight in kilograms per meter. For example, a B25 rebar has a nominal weight of 25 kilograms per meter.

Rebar sizes are also color-coded in Europe, with each size having a different color to aid in easy identification. The color coding system is as follows:

D8: Green

D10: Blue

D12: Yellow

D16: Orange

D20: Grey

D25: White

D32: Pink

D40: Light Green

Rebar sizes and standards in Europe play a crucial role in ensuring the quality and safety of concrete structures. It is essential to follow the correct size and standard requirements to ensure the structural integrity of buildings and infrastructure. Understanding European rebar sizes and standards is crucial for civil engineers and construction professionals working on projects in Europe.

The use of reinforcement bars, also known as rebars, is crucial in the construction industry to reinforce and strengthen concrete structures. In Europe, the sizing of rebars follows a standard chart that is commonly known as the European Rebar Sizes Chart. This chart provides a uniform and consistent system for specifying the sizes of rebars used in construction projects.

The European Rebar Sizes Chart is based on the metric system, and the sizes are measured in millimeters (mm). The chart categorizes rebars into different grades, each representing the minimum yield strength of the steel. The most commonly used grades in Europe include B500B, B500C, and B420C.

In the European Rebar Sizes Chart, the rebars are numbered from 2 to 28, with each number indicating the diameter of the bar. For example, a size 2 rebar has a diameter of 6mm, while a size 28 rebar has a diameter of 32mm. The chart also specifies the weight of each rebar per meter length for easy estimation during the construction process.

The standard length of rebars in Europe is 12 meters, but they can be supplied in custom lengths based on project requirements. The chart also includes a nominal weight per unit length for each size of rebar, which is used to calculate the total weight of rebars needed for a project.

One notable difference between the European Rebar Sizes Chart and the American Rebar Sizes Chart is the use of the letter ‘M’ to represent the unit for the weight of rebars, which stands for kilograms per meter. In contrast, the American chart uses the letter ‘lb’ for pounds per foot.

The European Rebar Sizes Chart also provides detailed information on the spacing and placement of rebars in concrete structures. This is crucial in ensuring that the rebars are placed at the correct distance and orientation to provide optimal reinforcement to the concrete.

In conclusion, the European Rebar Sizes Chart is an essential tool for civil engineers and contractors in Europe. It provides a standardized system for specifying rebars and ensures consistency and accuracy in construction projects. With this chart, engineers can easily determine the sizes and weights of rebars required, making the construction process more efficient and cost-effective.


In conclusion, understanding the various European rebar sizes and their corresponding chart is crucial for any construction project that requires reinforced concrete structures. It allows for a standardized and efficient construction process, ensuring structural integrity and durability. By familiarizing oneself with the sizing system and utilizing the chart provided, engineers and contractors can ensure that the correct rebar sizes are used for their projects, leading to a successful and safe end result. Additionally, being knowledgeable about the European rebar sizes and chart can also aid in reducing construction costs and mitigating any potential errors during the construction process. With this comprehensive guide, we hope that you now have a better understanding of All About European rebar and reinforcing bar sizes and chart.
