What Is Vertical Exaggeration?

Topographic profiles and cross-sections often use a smaller vertical map scale than horizontal scale so elevation changes remain visible. Vertical exaggeration is the ratio of those scale denominators.

Vertical Exaggeration Formula

$$\text{VE} = \frac{\text{horizontal scale denominator}}{\text{vertical scale denominator}}$$

Example: horizontal scale 1:24,000 and vertical scale 1:1,200 gives VE = 24,000 ÷ 1,200 = 20×. Elevations appear twenty times steeper than they would at equal horizontal and vertical scales.

Frequently Asked Questions

Why exaggerate vertical scale on maps?

Real terrain is often much wider than it is tall. Without vertical exaggeration, hills and valleys can look nearly flat on a profile drawn to true scale.

What vertical exaggeration is typical?

Geologic cross-sections commonly use 5× to 20× exaggeration depending on slope, map width, and the detail you need to communicate.

How do I enter map scales?

Enter the denominator only. For 1:24,000 horizontal and 1:1,200 vertical, enter 24000 and 1200.

Can vertical exaggeration be less than 1?

Yes. If the vertical scale denominator is larger than the horizontal one, VE is below 1× and vertical relief is compressed rather than exaggerated.
