Is an 8-1/4" jobsite saw enough, or do I need a 10"?

For ripping 2x material, sheet goods, and most trim work, an 8-1/4" saw like the DeWalt DWE7485 is plenty. Reviewers consistently point to depth of cut and dado compatibility as the trade-offs—10" saws cut thicker stock and most accept dado stacks, while most 8-1/4" jobsite saws do not. If you plan to mill thicker hardwood or run dadoes, step up to a 10".
