Patio Cover Beam Size Chart With Dimensions

When building a patio cover, it's crucial to choose the right beam size for adequate support. The beam size should be based on the span of the cover and the weight it must bear. Here is a patio cover beam size chart to assist you in selecting the appropriate beam for your project.

Patio Cover Beam Size Chart

Span (ft)	Beam Size (inches)
6-8	2x6
9-11	2x8
12-14	2x10
15-17	2x12
18-20	2x14

Note: These dimensions assume a span of 10 feet between supports. For longer spans or heavier loads, you may need to use larger beams.

Factors to Consider When Choosing Beam Size

Span:

The distance between the supports of the patio cover. *

Load:

The weight of the cover and any additional items it will support, such as a roof or lighting. *

Spacing:

The distance between the beams. Typically, beams should be spaced no more than 24 inches apart. *

Building Code:

Local building codes may specify minimum beam size requirements.

Tips for Choosing the Right Beam Size

* Consult with a structural engineer or contractor for professional advice. * Use a beam calculator to determine the required beam size based on specific project parameters. * Consider the height of the patio cover and the type of roofing material used. Heavier materials require stronger beams. * Choose beams made from pressure-treated lumber or cedar for outdoor durability. * Install beams with proper spacing and support to ensure stability and prevent sagging. By following these guidelines and choosing the appropriate beam size, you can ensure that your patio cover is structurally sound and provides years of enjoyment.
