## Concept

Proportional letters use varying advance widths.

## Example

All five specimens share a sentence, iiiWWW 0123, and the same numbers. Edit the specimen, adjust its size, and show measured width guides or tabular digits. Text remains shaped as one string. Reset or reload restores the initial text at 48px. The measured i and W advances differ; tabular digits can still align.

## When to choose it

Choose it for flowing text. Font coverage and number features vary; measure the loaded face rather than infer widths from its name.
