Make sense of big numbers
Your height is the starting point.
Enter your height, choose Height or Length, and add up to three objects beside your reference. Height compares vertical measurements from the stated base to the marked endpoint, including standing height, shoulder height or a sports fixture’s specified height. The endpoint may differ from the top of the outline. Length compares horizontal nose-to-tail or overall lengths.
In Length mode, your reference is a ruler equal to your height, not a person lying down. Use Zoom to inspect the diagram and Fit all to return to the full view. A tiny reference remains tiny: we never enlarge one object independently.
Each measured span equals its value in metres multiplied by the same scale factor. Width, shape, mass and volume are not being compared. Maximum animal sizes do not describe an average animal, and individual sizes vary.
