Flat and round characters

A term you'll meet in characterization.

The terms flat and round describe how complex a character is. The novelist E. M. Forster introduced them in Aspects of the Novel (1927), and they remain one of the handiest tools for talking about characterisation.

The flat character

A flat character is built around a single trait or idea and doesn't change. You can sum them up in a sentence: the loyal servant, the comic neighbour, the greedy landlord. Forster said a flat character could be expressed in one phrase — and that you remember them precisely because they never surprise you.

The round character

A round character is complex, contradictory, and capable of surprising the reader convincingly. They have inner lives, mixed motives, and the capacity to change. Most protagonists in serious fiction are round; they feel like people rather than functions.

Both are tools, not grades

"Flat" is not an insult. A novel full of nothing but round characters would be exhausting and unfocused. Flat characters do essential work — they populate a world, provide contrast, carry the comedy, and keep our attention on the figures who matter most. Dickens built unforgettable books largely from brilliant flat characters.

Flat/round vs. static/dynamic

Keep these axes separate. Flat versus round measures complexity; static versus dynamic measures change. A character can be round but static (deep yet unchanged) or flat but dynamic (simple yet altered). Naming both qualities gives a precise read on how a character is made.
