Drawing an Oval

Need to draw an oval for a panel? Here's how:
  • Calculate half the measurement of the longest line. In this example the long line is 340mm and the short axis is 200mm long.  So the diagonal is 170mm.

  • Measuring from the end of the shortest line, mark off this amount on the longest line, top and bottom. You can use a ruler or compass set to the correct length.
  • Insert a pin at both these points.

  • Place a piece of thread, string - or in this case a quick release tie - round one pin. Tie a knot in the thread at the far end of the longest line.
  • Put a pencil inside the loop. Pull the thread taut and begin to draw the oval.

For a leaded panel, the space occupied by the lead came will need to be accounted for in the measuring of the dimensions.
