Scale (indicators, human scale)

Use people, props, and measured markers to show the size and usability of a design.

What it is

Scale indicators show how large a design is. Familiar objects and people give viewers a known reference for comparison.

Human scale is a common anchor. Place a neutral, clearly drawn person beside a prop, vehicle, or environment to show height, reach, and usability. Keep the figure simple and quiet, with a believable height.

Finished concept sheets can repeat scale information through figures in multiple views, line silhouettes, or a numbered height bar. Use a consistent reference height across sheets, and align indicators with the ground plane and perspective.

Why it matters

Scale indicators help readers judge size and usability. Weak scale information can make an object seem toy-sized or oversized, and proportions such as door placement, window spacing, handle thickness, and step height may become difficult to assess.

You can check it when

• ✓Place a neutral human figure beside the design and check that the figure-to-design relationship communicates size without a caption.
• ✓Check that figures and props share the design's ground plane and perspective, with feet grounded and proportions consistent.
• ✓Compare multiple sheets and verify that the human reference keeps the same height and style.
• ✓Remove labels and check whether the design's size can still be described in everyday terms, such as handheld, car-sized, or building-sized.
