It's the great debate of the shape drawing world. Some people swear circles are easier — one smooth motion, no corners. Others argue that straight lines are more natural than curves. We looked at data across thousands of drawing attempts to find the answer.
On average, circles are the easiest shape to draw, with a mean score about 7 percentage points higher than squares. The difficulty ranking from easiest to hardest is: Circle → Square → Triangle → Hexagon.
But averages don't tell the whole story.
When we look at individual players rather than averages, an interesting pattern emerges. Players tend to fall into two categories:
"Curves people" score significantly better on circles and hexagons (which, with many sides, approximate a curve). They tend to draw with flowing, continuous motions and struggle with sharp direction changes.
"Lines people" score better on squares and triangles. They're comfortable with straight edges and precise angles but struggle to maintain a smooth curve. This group often includes people with technical drawing, architecture, or engineering backgrounds.
Three key factors make circles the easiest shape for the average player:
1. One continuous motion. A circle is drawn in a single, unbroken movement. There are no corners requiring sudden direction changes, which are where most errors occur in polygon drawing.
2. Forgiving scoring. A circle's score is based on deviation from the average radius. Small wobbles average out over the full circumference. With a square, any curve in what should be a straight line is immediately penalized.
3. Natural arm mechanics. Your arm joints naturally move in arcs. A circle aligns with these natural arcs. Straight lines, paradoxically, require more against-the-grain effort because your joints don't naturally produce straight trajectories.
Despite the averages, roughly 25% of players score higher on squares than circles. Here's why:
1. Predictable geometry. A square has four clear, discrete steps: draw right, draw down, draw left, draw up. Some people's brains prefer this structured approach to the continuous, "feel-based" motion of a circle.
2. Straight-line confidence. If you're trained to draw straight lines (technical drawing, architecture, casual doodling of boxes), your motor programs for straight edges are already refined.
3. Corner checkpoints. Each corner gives you a moment to assess and reset. With a circle, there are no natural pauses — a mistake compounds through the entire motion.
Hexagons are the hardest shape by far, averaging 14 points below circles. But there's a surprising subset of players who score higher on hexagons than on triangles. These tend to be players with good spatial awareness who can divide space into six equal parts intuitively — a skill that may correlate with mathematical thinking.
For most people, circles are easier. But the real answer is that it depends on your brain and training. The only way to know is to try all four and compare.
