How to measure proportions with a pencil in drawing

1. To measure proportions with a pencil
2. 1. 1. Outstretch your hand fully.
      2. Close one eye.
      3. Align the top of the pencil with the top edge of the object and mark the bottom edge of the object on the pencil with a fingernail.*
      4. Hold the pencil parallel to the plane of your eyes. In other words, don’t lean it away or towards yourself.
      5. Holding your nail in the same place on the pencil, rotate your hand so that the pencil becomes horizontal. Now measure how many times you can fit the height in the width (and vice versa), making imaginary marks on the pencil and moving the hand with the marked size.
      6. If the proportions are 1 to 2, 1 to 3 and so on, mark the size of the pencil from the “imaginary marks” on the object.
      7. If the sizes are not corresponding as a ratio, try to understand approximately which part has the remainder (a third of the size, two thirds, a half and so on).
      8. If the top and the bottom of an object are not on the same vertical axis, move the graphite of the pencil to the top edge, then accurately and horizontally move your hand to the place where the bottom edge is and mark the bottom edge with your fingernail.
      9. Always start with marking sizes and proportions of objects on the paper by eye and only after start to measure with a pencil.

3* You can also start to measure horizontally.

5* If you measure the ratios of vertical parts, you don’t need to rotate the pencil.
