Wood Measurements
Ever notice that when you buy wood you rarely get what you ask for? For instance a 2" by 4" is really 1 1/2" by 3 1/2". Sometimes you get the length correct, for instance that same 2"x4"x12' is really twelve feet long.
Wood Measurements (Hover)
Wood measurements are measured at their rough cut dimensions. Once they are refined they are a bit smaller thus a 2X4 is a 1 1/2 by 3 1/2. You can buy some bigger woods at the bigger size like a 6X6 or a 6X8 or ask around for local lumber mill that will sale you rough cut boards. If you do that you may have to let the wood cure for a time before you can use it.
