Dimensions are 3 1/2 " by 3 1/2" in cross-section, 9 are 9 feet long, 3 are 3 1/2 feet long, and 4 are about 2 feet long. I have been using them to line my garden beds and pathways. They are of treated wood, but some of them have surface decomposition on one or more sides where they were in contact with the soil.
