All About LVL beam span calculator

The use of LVL (Laminated Veneer Lumber) beams has become increasingly popular in construction due to their strength, durability, and versatility. However, determining the appropriate size and span for LVL beams can be a complex and time-consuming process. To simplify this task, the LVL beam span calculator was developed. This powerful tool allows builders and engineers to quickly and accurately calculate the size and span of LVL beams for various construction projects. In this article, we will delve into the details of the LVL beam span calculator and its benefits in ensuring safe and efficient construction practices.

A Laminated Veneer Lumber (LVL) beam span calculator is a useful tool for civil engineers in determining the appropriate size and spacing of beams for structural support in buildings and other structures.

LVL is a type of engineered wood product made from multiple thin layers of wood veneers bonded together with adhesive. It is known for its high strength, durability, and versatility, making it a popular choice for structural applications.

The LVL beam span calculator takes into account several factors such as the load bearing capacity, span length, and deflection limits of the beams. It uses these inputs to calculate the appropriate size and spacing of beams to ensure that they can safely support the required loads without excessive deflection or failure.

To use the calculator, the engineer would need to enter the specific design criteria such as the type of load (dead, live, wind, or seismic), span length, and the type of load distribution (uniform or point loads). Based on these inputs, the calculator would provide the recommended beam size, spacing, and allowable deflection value.

The beam size is usually expressed in inches or millimeters, while the beam spacing is typically given in feet or meters. The allowable deflection, which is the amount of bending the beam can experience without causing damage to the structure, is measured in inches or millimeters per unit of span length.

While most LVL beam span calculators are computer-based, there are also online calculators available for quick and easy calculations. These online tools often have pre-determined values for common design criteria, making it easier for the engineer to input the necessary information and obtain the results.

Some advanced LVL beam span calculators also take into account additional variables such as the modulus of elasticity and shear strength of the beams. These factors can affect the overall structural integrity of the beams and should be considered in more complex design scenarios.

In conclusion, LVL beam span calculators are essential tools for civil engineers in designing safe and efficient structures. They provide accurate and reliable calculations for the appropriate size and spacing of beams, taking into account various design criteria and ensuring the structural stability of a building or structure.

Rule of thumb for sizing LVL beam

Rule of thumb for sizing LVL beam

The Rule of Thumb for sizing Laminated Veneer Lumber (LVL) beams is a commonly used method in construction to quickly estimate the size of beams needed for a particular span and load.

In general, LVL beams are used in structural applications where a larger and stronger beam is required but solid sawn timber beams are not feasible. LVL beams consist of several layers of thin wood veneers that are glued together to form a strong and durable beam. They are known for their strength, stability, and dimensional consistency, making them a popular choice in construction projects.

When it comes to sizing LVL beams, the Rule of Thumb method is often used as a starting point to determine the approximate size of the beam needed. This method takes into account the span of the beam and the load it needs to support. It is based on the assumption that the beam will be supporting a uniformly distributed load and will not be subjected to any point loads.

The general rule is to use one inch of LVL beam depth for every foot of span. For example, if the span is 15 feet, a 15-inch LVL beam would be used. However, this rule may vary depending on the type of LVL beam being used and the specific load and span conditions. It is always recommended to consult a structural engineer or use a more accurate calculation method for a specific project.

In addition to the span, the load on the beam also needs to be considered when using the Rule of Thumb method. The common practice is to assume a load of 50 pounds per square foot for residential applications and 100 pounds per square foot for commercial applications. The span multiplied by the assumed load per square foot will give an estimated total load on the beam.

It is important to note that the Rule of Thumb method is just a rough estimate and should not be solely relied upon for the design and construction of LVL beams. Factors such as the type of LVL beam, deflection criteria, and lateral support conditions also need to be carefully considered in the sizing process.

In conclusion, the Rule of Thumb for sizing LVL beams can be a quick and convenient method, but it should always be verified by a structural engineer or used in combination with more accurate calculation methods. It is crucial to ensure that the beams are properly sized and able to bear the intended loads to ensure the structural integrity and safety of the building.


In conclusion, the LVL beam span calculator is an incredibly important tool for architects, engineers, and builders to accurately determine the appropriate span length for LVL beams in their construction projects. By inputting key factors such as building codes, beam properties, and load requirements into the calculator, it offers a quick and reliable solution for calculating beam spans. Additionally, the versatility and efficiency of the LVL beam make it a popular choice for construction projects, and utilizing the LVL beam span calculator ensures that these beams are used effectively and safely. Overall, the LVL beam span calculator plays a crucial role in modern construction and is a valuable resource for creating strong and stable structures.
