Lesson 20

Sketching Proportional Still Life

Recommended resources

Introduction

Welcome to the final lesson of our module on Measuring and Proportions. Over the last few lessons, you've built a powerful toolkit for observational drawing. You've learned to use comparative measurement to judge relative sizes, applied the unit-measuring technique with your pencil, used alignment lines and negative space to verify your construction, and practiced recognizing and correcting common errors.

Today, we bring it all together. Your goal for this lesson is to sketch a still life composition, focusing on maintaining accurate proportions between multiple objects. This is the capstone project for this module. It's where you move from practicing individual techniques in isolation to deploying them as part of an integrated, systematic workflow to create a cohesive drawing. Think of it as moving from writing small, single-purpose functions to building a complete application that uses them all to achieve a complex task.

The Process of a Still Life Drawing

A successful still life drawing relies on a structured process that moves from the general to the specific. This "big to small" approach ensures your foundation is solid before you invest time in details. We can break this process down into four main steps.

Step 1: Compose and Contain

Before you draw a single object, you must first decide on the overall composition.

  1. Frame Your View: Look at your still life setup. Use your hands or a simple cardboard cutout (a "viewfinder") to frame the composition you find most interesting.
  2. Establish the Bounding Box: Measure the total height vs. the total width of your entire chosen composition. Lightly draw a rectangle on your paper with these same proportions. This is your "bounding box." All of your objects will live inside this box. This simple step prevents the common problem of running out of paper or having your drawing awkwardly placed.

Step 2: Measure and Block-In

With the overall container established, you can now place the objects within it.

  1. Choose a Base Unit: Select one clear, moderately-sized element in your composition to be your "unit of measure." The width of a mug, the height of an apple, or the width of a book are all good candidates.
  2. Block-In Major Forms: Use your unit to measure the main objects and place them within the bounding box as simple geometric forms (spheres, cubes, cylinders), just as we did in Module 2. How many "units" tall is the bottle? How does its width compare to your unit? Don't draw details yet; focus only on the correct size and placement of these basic shapes.
Step-by-Step Still Life Sketching
This image shows the progression from simple block-in shapes (Step 1) to a refined drawing. Your goal for today is to master the first few steps, ensuring the initial construction is proportionally accurate.
Still Life Proportions: Comparative Measurement Example
This is the goal of your measurement: to understand how the size of each object relates to a base unit (in this case, the white cylinder). The bottle is 1.75 times the cylinder's height, the pear is 0.5 times, and so on.

Step 3: Verify and Refine

This is the most critical step. Here, you continuously check your work and make corrections. This is an iterative loop, not a one-time check.

As a quick refresher on the key tools for this stage, let's watch a short video.

Drawing Measuring Techniques

This video from Proko will serve as a quick practical review of two powerful verification tools: plumb lines (vertical alignment) and negative shapes. Notice how he uses them to check the relationships between different parts of the drawing.

Watch the segments on 'Plum lines' (07:22 - 08:32) and 'Negative shapes' (09:55 - 11:10). Focus on how you can use these techniques to find and fix errors in the placement of your blocked-in shapes.

Use these tools in a "check loop":

  • Plumb/Level Lines: Check vertical and horizontal alignments. Does the right side of the book line up with the left side of the apple?
  • Negative Space: Look at the empty shapes between your objects. Are the shapes of those gaps correct in your drawing? This is often easier to see than the positive shapes of the objects themselves.
  • Angle Sighting: Check the important angles, like the slope of a tabletop or the line connecting the top of two different objects.

Erase and adjust your simple block-in shapes until these relationships are correct.

Step 4: Finalize the Line Art

Only when you are confident that the size, placement, and proportions of your basic forms are correct should you refine their contours. Solidify your construction lines and draw the final outlines of the objects. For this lesson, we will stop here, with a clean and accurate line drawing.

Main Exercise: Still Life Proportion Study (35-40 minutes)

Now it's time to put this four-step process into practice.

1. Setup (5 minutes)

  • Choose 2-3 household objects with different basic shapes (e.g., a cylindrical mug, a boxy book, a spherical orange).
  • Arrange them on a table in front of you. Make sure they are relatively close together and that at least one object partially overlaps another. This will create interesting negative spaces for you to measure.
  • Ensure your lighting is simple and from one primary direction.

2. Execution (30-35 minutes)
Follow the four-step process to create an accurate line drawing of your still life.

  • Step 1: Compose and Contain (~5 mins)

    • Frame your view and lightly draw the overall bounding box on your paper.

  • Step 2: Measure and Block-in (~10 mins)

    • Select your unit of measurement.
    • Using that unit, sketch the basic geometric forms for each object inside the bounding box. Keep your lines very light.

  • Step 3: Verify and Refine (~10 mins)

    • Begin your "check loop." Use plumb lines, level lines, and negative space to check your work.
    • Don't be afraid to erase and adjust. This is where the drawing is truly made. Ask yourself questions: "Is the negative space between the mug and the book the right shape?" or "Does the top of the orange align horizontally with the middle of the mug?"

  • Step 4: Finalize the Line Art (~5-10 mins)

    • Once you are satisfied with the proportions of your block-in, go over your lines to create a clean, confident contour drawing of the objects. Erase any unnecessary construction lines.

The goal is a finished line drawing where the objects feel correctly sized and placed in relation to one another. Do not add any shading.

Conclusion

Excellent work. You have now successfully integrated all the skills from this module into a single, complex drawing exercise. By following a systematic process—compose, contain, measure, block-in, and then verify—you can build drawings on a foundation of accuracy.

Key Takeaways:

  • A structured, four-step process (Contain, Block-in, Verify, Refine) is key to managing the complexity of a multi-object scene.
  • Always work from "big to small." Establish the overall composition before placing individual objects.
  • Verification is not a final step but a continuous loop. Constantly check your work with plumb lines, negative space, and angle sighting.
  • Proportional accuracy is achieved during the light, erasable construction phase, not in the final details.

You've now completed the module on Measuring and Proportions! You have a solid command of how to create an accurate structural drawing. In our next module, "Understanding Light, Form, and Shadow," we will build directly on this foundation. You'll learn how to take your accurate line drawings and make them feel solid and three-dimensional by applying light and shadow.
