Doesn't matter which program used for the layout, most of them do have pretty small pads. These small pads are ok for a commercial board with solder mask, but for a home etched board I find it's better to use larger pads. My pads and traces are usually a good bit larger than standard. This helps prevent problems of pads lifting during rework as most of my boards are prototypes requiring removal of parts a few times.... sometimes I get lucky and do the design correct first time.
Just make the pads as large as you wish.
