A portrait presents you with a face. The face is the most information-dense surface that human perception has evolved to read: we are wired, from infancy, to extract emotional state, social status, attention direction, and intention from the configurations of eyes, mouth, and brow. When you stand in front of a portrait painting, this deeply ingrained system activates automatically. You form an impression of the sitter before your conscious attention has had time to look carefully. That impression is often accurate and always worth examining, because it tells you something about what the painter communicated successfully. But it is only the beginning of what the portrait offers.
Reading a portrait carefully involves attending to five main areas: the gaze, the expression, the hands, the posture and clothing, and the setting. Each of these areas communicates independently and in combination with the others. Understanding what each layer of information carries, and how the great portraitists of history have handled it, transforms the experience of portrait galleries from a sequence of faces into an encounter with a tradition of psychological and social observation that spans six hundred years.
The Gaze: Where Are They Looking, and What Does It Cost?
The gaze in a portrait does three things: it establishes a relationship with the viewer, it reveals or conceals emotional state, and it encodes social meaning. These three functions pull in different directions, and how a painter balances them is one of the central technical and psychological challenges of portraiture.
Direct eye contact in a portrait, where the sitter looks straight at the viewer, creates the illusion of mutual attention. The viewer feels seen, and this creates an intimacy that drives much of portraiture's psychological power. But sustained direct eye contact is also a social signal with complex connotations: it can read as confident, challenging, vulnerable, or intimate depending on what the rest of the face and body communicate simultaneously. Rembrandt's late self-portraits are the supreme example: the direct gaze is unflinching but not aggressive, curious but not destabilised, aged but not resigned. The viewer feels they are genuinely met, not performed to.
Rembrandt van Rijn, "Self-Portrait" (c. 1665), oil on canvas, 114.3 x 94 cm. Kenwood House, London. In this late self-portrait, the direct gaze and unflinching honesty about age and vulnerability create one of the most psychologically complex encounters in all of painted portraiture. The handling of the eyes, with their specific mixture of tiredness, intelligence, and quiet attention, is the technical and emotional heart of the work. Image: Public domain, via Wikimedia Commons
Averted gaze, where the sitter looks away from the viewer, communicates something entirely different. It can suggest that the sitter is lost in thought (inner life, intellectual depth), is attending to something outside the picture frame (narrative context, social situation), or is emotionally retreating from view (modesty, grief, evasion). Vermeer's "Girl with a Pearl Earring" (c. 1665) is a famous case of the calculated averted-to-direct gaze: the figure appears to have turned at the moment of the viewer's approach, creating the illusion of caught motion. The eyes are not fully engaged; they are in the process of engaging, and this transition state is what gives the image its particular intimacy.
Expression: What the Mouth and Brow Say
The open mouth in portraiture is relatively rare in the Western tradition before the 19th century, because showing teeth was associated with extreme emotion (laughter, anguish), social lowness, or loss of self-control. Formal portraiture of the aristocracy and wealthy merchant classes maintained closed mouths as a baseline social signal: the subject is composed, in command of their responses. The slight smile, which appears with increasing frequency from the late 15th century onward, required particular technical care, because a smile changes the relationships between every element of the face simultaneously, and the difference between a convincing smile and an unconvincing one is registered immediately by the viewer's automatic social cognition.
Leonardo da Vinci's extended work on the Mona Lisa (c. 1503-1519) was substantially about the challenge of the smile: how to paint a mouth and eyes in a relationship that produces the sensation of shifting between two emotional states, so that the expression seems to change as the viewer moves or looks away and looks back. His use of sfumato, the soft-focus blending of edges, specifically around the corners of the mouth and eyes, makes both areas resist definitive reading. The brain's automatic expression-reading system cannot settle on a single interpretation, and the restless, involuntary searching for resolution is what produces the Mona Lisa's legendary effect.
Hands: The Second Face
In portraiture, hands are the second most expressive area of the human body after the face, and painters who handle hands well consistently use them to extend and complicate what the face alone communicates. Hands can display social status (through rings, gloves, and the gestures of leisure versus labour), emotional state (tightly clasped, relaxed, anxious, authoritative), and character (the large, rough hands of a working man described with the same care as a scholar's fine-fingered reach toward a book).
Hans Holbein the Younger's portrait of "The Ambassadors" (1533) is a masterclass in hand and object use. The two French diplomats stand before a table covered with scientific instruments, globes, and books. Their hands rest on, point toward, and gesture at these objects with studied informality. The hands encode the sitters' intellectual interests, their social sophistication, and their command over the world represented by the instruments. Without the hands and the objects they interact with, the two figures would be portraits of physical appearance. With them, they become portraits of minds and ambitions.

The hands are as carefully described as the faces: each figure's hand position relative to the scientific instruments conveys intellectual ownership of the knowledge the instruments represent.

John Singer Sargent (1856-1925) built his reputation largely on his ability to paint hands. His virtuoso brushwork, which could describe the fall of light on silk and the specific quality of nervous tension in a clenched hand in a few apparently effortless strokes, made hands central to his portraits' expressive economy. In "Madame X" (1884), the subject's downward-pressed hands gripping the table edge communicate the effort of composed self-presentation with a directness that the controlled expression of her face withholds. The hands tell you what the face will not.
Posture, Clothing, and Setting
Posture communicates social status and internal state simultaneously. Upright bearing, weight evenly distributed, gaze forward: the standard posture of authority in official portraiture. Leaning, turned slightly, one shoulder higher than the other: signals of informality, ease, or the relaxed confidence of someone who does not need to perform their status. The rigid frontal posture of medieval portraiture communicated hieratic solemnity. The relaxed contrapposto (weight shifted to one leg) that appears in Renaissance portraiture communicated classical ease, humanism, and the sitter's education in antique traditions.
Clothing in portraiture is documentary evidence. 16th-century northern European portraiture allows art historians to trace the introduction of specific fabric patterns, the development of the ruff, and the adoption of particular fashions across social classes and national borders, because painters were commissioned to record the sitter's wardrobe with the same fidelity as their face. But clothing also communicated social aspiration, political allegiance, and religious affiliation in ways that contemporary viewers understood immediately and modern viewers require historical knowledge to decode.
Reading a Portrait in Practice
The approach that produces the richest engagement with any portrait is sequential: start with the overall impression (what do you feel, immediately and automatically?), then move to the gaze (what is the quality of the eye contact?), then the expression (what is the relationship between the eyes and the mouth?), then the hands (where are they and what are they doing?), then the posture (what does the body position communicate about effort, ease, and status?), and finally the setting (what do the background and props encode about the sitter's identity and aspirations?).
This layered approach is directly connected to the broader practice of looking at art systematically, and the portrait format rewards this method because so much is deliberately encoded at each layer. For how portraiture functions within the longer history of figure representation, our guide to figure drawing covers the anatomical and compositional principles behind depicting the human body convincingly.
Final Thoughts
Every portrait is a negotiation: between the painter's perception and the sitter's self-presentation, between the social conventions of the period and the individual psychology of both parties, between what the patron wants to communicate and what the painter's honesty compels them to include. Reading this negotiation, attending to where the painter confirms the social performance and where they complicate it, is the central pleasure of portrait-looking. It requires no special knowledge to begin, only the willingness to spend more than a few seconds with any face you find compelling.
