I want to draw a line.

Graphics[{Line[{{0, 0}, {10, 0}}]}]


enter image description here

Note that changing the end point does not affect the displayed line.

Graphics[{Line[{{0, 0}, {20, 0}}]}]


enter image description here

But I want to draw a longer line. How to do it?

    $\begingroup$ Add Frame -> True at the end of Graphics to see what happens. Look up ImageSize and AspectRatio to control the graphics size and shape. $\endgroup$

While the scale answer is technically correct, what you really are trying to do, is to prevent the background from continually resizing to accommodate graphical contents.

The option you want is PlotRange->{{Xmin,Xmax},{Ymin,Ymax}} (optionally, Zmin,Zmax for 3D graphics. Another 2 options which affect the output size are ImageSize and AspectRatio. One scales the whole graphic, another "squishes" the graphic to accommodate a given Y:X ratio. So AspectRatio->2 would give you a vertical rectangle, and AspectRatio->1/2 - a horizontal one, while AspectRatio->1 is a perfect square.

Try this:

          (* your graphics directives here *)
         }, PlotRange->{{0,50},{0,50}}, AspectRatio->1, ImageSize->800]



If you have to draw only one line, then it will be automatically scaled as in your example. You can make this line bigger by clicking on the image and make the borders bigger with the mouse...

If you draw two lines then you will see the correct result (ratio)

Graphics[{Scale[Line[{{0, 0}, {10, 0}}], 3], Line[{{0, 1}, {10, 1}}]}]

in the example above the first line can be scaled
