Four inches and three inches, and six inches tall. I make it in two pieces and then glue them together. It is split down the center of the fish so each piece measures 6"x 4"x 1 1/2". The curve of the fish side I cut on my band saw because it is too wide (4") for my scroll saw but I cut the cross out,(1 1/2") after that cu,t with my scroll saw. The largest of these I can make, using just my scroll saw only, is 3" tall.
