This number represents the maximum distance between rafters for your particular situation.įor example, suppose you plan to use spruce-pine-fir lumber, 2×4 rafters, spaced 16 inches apart, and a 4:12 roof pitch. Locate the appropriate column and row in the chart and find the corresponding number. To use the chart, you need to know the wood species, rafter size, spacing, and roof pitch you plan to use. The rows represent different roof pitches, ranging from 1/4:12 to 12:12 (or flat to steep). The columns represent different wood species, rafter sizes, and spacing. The chart consists of a table with several columns and rows.

When using the 2×4 rafter span chart, be sure to select the appropriate roof pitch based on the weight of your roof and the length of the span. In general, steeper roofs can handle more weight than flatter roofs. The pitch of your roof can also impact the strength and stability of your rafters. This will ensure that your roof can support the load without sagging or failing. When using the 2×4 rafter span chart, be sure to select the appropriate spacing between rafters based on the weight of your roof, the length of the span, and the size of your rafters. In general, the closer your rafters are spaced, the stronger your roof will be. The spacing between your rafters is another critical factor to consider when using the 2×4 rafter span chart. When using the 2×4 rafter span chart, be sure to select the appropriate rafter size based on the weight of your roof, the spacing between rafters, and the length of the span. In general, larger rafters can span longer distances without sagging or failing. The size of your rafters can also impact their strength and ability to support weight.
This will ensure that your rafters can handle the load and last for years to come.

The 2×4 rafter span chart is a tool that helps you determine the maximum allowable span between rafters based on the size and species of the wood, the spacing between the rafters, and the roof pitch. This distance determines how much weight the rafter can support without sagging or failing.įor example, if you’re building a shed with a 10-foot span between the walls, you need to use rafters that are strong enough to support the weight of the roof and any snow or wind load that it may experience. The span of a rafter refers to the distance between two supports, such as the walls or beams that the rafter is attached to. Rafters are typically made of wood and come in different sizes and shapes, depending on the design and load requirements of the roof. A rafter is a structural component that supports the weight of a roof and transfers it to the walls or beams below. What is a 2×4 Rafter Span Chart?
