Facial thirds and drawing conventions

Some familiar facial proportions come from artistic conventions. Their history does not make them universal targets.

Distinguish a convention from evidence

Equal divisions can help an artist construct a face. That is different from a study establishing a representative range or a personal benefit from changing a proportion.

Photographs introduce another layer

Landmark placement and perspective affect a calculated division. Hairline visibility, expression, and framing can also complicate interpretation.

Read without ranking

Use a proportion as descriptive context when it is relevant. A difference from a drawing convention is not a defect and does not establish a need for intervention.
