Try to redraw this PCB on a raster paper (0.1"). Measure all components you intend to use in this circuit and confront them with what you see on this drawing and accept, or if your component is bigger/smaller correct its position and pins on your drawing.
Remember, good drawing is worth millions; it is your plan, so if you spend more time planning - how and where position certain components - the less time you will waste during construction phase.
Typical approach in designing PCBs is to make them as small as possible. When you start learning PCB design, I would not worry much about this issue. Make your first PCBs of convinient size, so when you wire them up you have enough room for connections.
Other thing is that you can learn how to develop your own PCB at home using plain PCB, PCB marker and etchant ..
