How to Avoid Flat Characters in Your Story

Has an editor or critique partner said, “Your character is flat” when offering feedback on your story? Or perhaps they worded it another way: “Your protagonist didn’t grab me,” or “This character needs more depth.”

However it’s phrased, being told we’ve missed the mark on a character is a bit of a gut punch. But it’s okay. Flat characters, like anything else, can be fixed.  

A flat character is one-dimensional, lacking the depth and human complexity required to feel true to life. Not only do they seem unrealistic, they also fail to capture a reader’s curiosity or interest.

Flat characters can be written as such on purpose: a surly shopkeeper unwilling to bargain on price or the nosy neighbor trying to unearth your protagonist’s secrets. These types of characters have a small role or specific function (comic relief, mentorship, etc.) and don’t need a lot of depth.

But if an important character is seen as
shallow or boring…we have a big problem.

Characters are the heart of a story. For readers to care about them, they must feel like real people. Distinct personalities, belief systems, emotions, and histories shape them and their behavior. Personal needs, desires, struggles, and worldviews give them depth. All this, and a capacity for growth, is the magic recipe that will draw a reader in. 

What Causes a Flat Character?

Characters can feel underdeveloped for many reasons, but it often comes down to one thing: something essential about them has been overlooked. Some common offenders:

Shallow Backstory

A character’s past influences who they become, how they behave, and how they view the world around them. If a character’s backstory is missing, weak, or generic, their behavior may lack credibility or be inconsistent.

The Cure: Go deeper. Explore their past, including their emotional wounds, experiences, life lessons, fears, and insecurities.

A Too-Basic Personality

A character’s personality should contain specific traits that emerge because of their history/upbringing, the people who influenced them, and formative their life experiences, both good and bad. When writers gloss over the building out of a unique personality, they tend to give character ‘typical’ traits and so they come across as generic and unrealistic.

The Cure: People are complex, and characters will be, too. Spend time thinking about who your character is and why, and the traits most likely to appear in their personality. Be sure to also understand how negative experiences lead to personality flaws (and the behaviors and tendencies that go with them). Each character should have a mix of traits as no one is ever all good or bad.

Over-Reliance on Character Tropes or Stereotypes

Due to their familiarity, using character tropes (e.g., the villain, reluctant hero, or absent-minded friend) can fast-track the reader’s understanding of a character’s role. But leaning on one too hard turns them into a stereotype or cliché, which is a huge turnoff.

The Cure: Use any trope generalizations as a starting point only. Do the work and make each character someone fresh. Readers loved to be surprised by interesting and meaningful qualities that elevate the character in ways they didn’t expect.

Tunnel Vision

Characters who are only about one thing—the mission or goal, proving loyalty, success, etc.—come across as one-dimensional and unrealistic. For readers to connect with characters, they need to have relatable life layers. Relationships and social interactions. Dreams and desires. Responsibilities. Quirks, interests, problems.

The Cure: Real people can get obsessive about certain things, but they have other things going on. To give your character a better balance, imagine their entire life, not just the plot of your story. Explore how your character’s professional life or obsessions may collide with their personal life.

A Lack of Drive

In the real world, it can take time for us to know what we want, but in fiction, characters must be motivated and act. If your protagonist is wishy-washy about what they want or can’t settle on a goal, they’ll come off as weak.

The Cure: Characters who lack urgency when it comes to choosing or achieving a goal need to be put in the hot seat. Raise the stakes. Add conflict and tension. Make it clear that doing nothing leads only to pain and consequences. Additionally, know your character inside and out (#1) because past trauma, fears, and negative interactions will point you to their soft spots and unmet needs.

Distanced Emotions

Showing a character’s emotion, even when they’re trying to hide what they feel, is one of the most important tasks a writer has. Emotions are central to the human experience, and readers expect a front-row seat to whatever the character is feeling. When someone is closed off or seems imperviable to vulnerability, readers find it unrealistic.

The Cure: Become an expert at showing your character’s emotions, even when they try to hide what they feel from others. Readers must always be in the loop to empathize and feel invested. Understand how each individual will express emotion in their own way based on their personality, comfort zone, and backstory.

Inadequate Internal Conflict

A well-developed character should have inner struggles, doubts, conflicting needs, fears, and insecurities, all of which make certain actions and decisions agonizing for them. If a writer doesn’t know a character well enough, their struggles will seem generic and readers will feel disconnected from their struggles.

The Cure: Understand your character inside and out, especially backstory and unresolved wounds that haunt them (#1). Know their life, their stresses, their pain, and how loyalty, expectations, or beliefs may tear at them so you can show powerful, meaningful inner conflict. Use psychology in fiction to show inner turmoil in ways readers recognize as they’ve experienced the same tendencies themselves.

Little to No Growth or Change  

In any story, characters will face challenges—often life-changing ones. Even in a flat arc, where the protagonist remains steadfast in their beliefs, they should still learn, adapt, and navigate obstacles in a way that feels authentic. Primary characters who respond to every problem the same way, repeat mistakes without growth, or remain rigid in their viewpoints can feel unrealistic and unconvincing to readers.

The Cure: All roads lead back to characterization. Go deeper. Get to know your character, and why they think, act, and behave as they do. Choose specific conflict scenarios that force them to confront misconceptions and fears that lead to change and growth.
