What size blank should I get for my design?

US Blanks have a general surfboard rocker and outline. You will need to cut an outline with all blanks that we sell.  When selecting a US Blank you should try to find a blank that fits the dimensions of the board you are trying to shape.  US blanks are a close tolerance blank which mean that the outer part of the blank is the strongest foam and as you get closer to the center the foam will get softer, which makes blank selection critical to the strength of your surfboard. 

EPS blanks are uniform density throughout so you can get one a bit thicker than your finished board dimensions and shape away. EPS blanks are hotwire cut from a block of foam and have a rectangular outline which allows you the freedom of any outline you choose to cut.
