Managed to finish with Day 5 of Week 5 of The Art & Science of Drawing and with this, Week 5. Three more weeks to go.

Proportional Comparison

  • before drawing, analyze your subject
  • do some simple measurements to determine
    • width to height ratios
    • find some useful unit
  • try to find some simple shapes (ovals, lines, rectangles) and how they relate one to the other


  • start with the biggest shape or the bounding box
    • choose your unit
    • use your unit to draw the rest of the box
  • try to draw other lines or curves that you can determine by measurements alone

Angle sighting

  • using points determined during measuring step, triangulate other points
    • not every aspects needs to be measured in order to be drawn
    • it's up to you how much you want to measure
  • once a point is triangulated, you can draw lightly some context
    • this way you don't have to remember what the point is about
    • you can move freely all over the drawing and come back later for corrections
  • move back and forth between measuring and drawing
  • at some point, you'll have enough points so that you can only draw, knowing everything is in proportion
  • if you are unsure of something, go back to measuring

Closing thoughts

  • there is no single measuring recipe that you can apply to all your drawings
  • use the recipes as soft rules and adapt them to your subject and style
  • you now have a toolkit of measuring techniques, but it's up to you how you use them
    • use proportional measurements when you want to know how big or small a thing is in relation with another
    • use angle sighting when you want to know the location of a particular point


  • find 3 objects of moderate complexity
    • not too simple
    • not too complex for your current skill level
  • measure and draw each subject using the tools and strategies you've learned
  • experiment with different strategies of using the tools:
    • start with a light sketch and then measure
    • start with the measurements
  • leave the measuring lines on the page
    • you can erase wrong measurement lines
    • in future projects you can erase the measuring lines, too
