All of our standard leather hides are vat dyed, top-grain hides finished to automotive grade specs. We do not use any split, bonded, or reconstituted hides. Split, bonded, or reconstituted hides are lower-quality hides that may be good for some applications, but they would not be appropriate for an automotive application. Our standard leather hides are a completely natural product which means that they will vary in shape, size, and yield. Typically, you will want to take some general dimensions of the pieces you are going to recover with leather and add these dimensions together to get a rough requirement on the square footage of material required for your project. Leather hides are not measured by the yard like vinyl, but rather they are measured by square feet. We specifically sell our leather by the quarter hide; half hide, or whole hide. Average hide sizes are 40-45 square feet for a whole hide.
