1'X12' for the vertical parts. I cut the ends of the 1X12 to make 2 cross braces to space the hive supports wide enough to hold my supers and equipment off the "ground" when I need to set them aside. The foot braces are 6"X12' along the bottoms for extra stability. All of the woodenware is stained with pecan stain and sealed with Helsman Urethane semi-gloss Varnish to preserve them almost forever. I did the outside of my hive bodies only. I forgot to do the top feeder, so after I get these guys established, here comes the stain and sealant.
The back porch is only temporary until some shrubs and flowers build up in about a year. Then they are going off the back deck by the woods on some cinderblocks to keep them 18"+ off the ground.
