Updated: Oct 8


7-38-55 Rule
Wilson Luna Reviews | Leadership

Have you ever felt like your words alone weren’t getting the message across? That’s because effective communication goes far beyond what you say. In fact, research shows that only 7% of communication is based on words, while 93% is shaped by tone of voice and body language. This is the essence of Dr. Albert Mehrabian's 7-38-55 Rule, a powerful framework that reveals just how much more we convey through non-verbal cues.


In this blog, we’ll break down the rule and dive into each element—verbal, vocal, and non-verbal communication. You’ll also discover practical tips to improve your words, voice, and body language, helping you master the art of communication and create deeper connections with others.

What is Mehrabian’s 7-38-55 Rule?

The 7-38-55 Rule is a theory in communication first proposed by psychologist Dr. Albert Mehrabian in the 1970s. He explored how people interpret mixed messages, particularly in emotionally charged or ambiguous situations, and concluded that three elements play key roles in communication: the actual words spoken, the tone of voice, and body language.



Breaking Down the 7-38-55 Rule


  • 7% Verbal: This refers to the actual words used in communication. Whether it’s a speech, a conversation, or a simple request, only 7% of the impact of your message comes from the words you say.


  • 38% Vocal: How you say the words—your tone, pitch, and pace—contributes to 38% of the impact. A phrase can be interpreted differently depending on whether it's said with excitement, sarcasm, or boredom.


  • 55% Non-Verbal: The majority of your message comes from body language—facial expressions, gestures, posture, and even eye contact. These non-verbal cues can reinforce or contradict the verbal message.

Context of the Rule

It’s important to note that Mehrabian’s rule applies primarily to situations where emotions and attitudes are being communicated. In factual communication—like giving instructions or data—the verbal content holds more weight. However, in personal and professional relationships where emotions and impressions play a significant role, the 7-38-55 Rule becomes critical in ensuring that your message is received as intended.




The 7%: Mastering the Power of Words

Though words account for only 7% of communication in Mehrabian’s rule, they are still incredibly important. They are the foundation of any conversation, speech, or written communication, and they provide the framework around which tone and body language build.



The Importance of Word Choice

Words can inspire, motivate, or destroy, depending on how they’re chosen and used. The right words can leave a lasting impression, while the wrong ones can cause confusion or even damage relationships. In fact, miscommunication costs smaller companies with 100 employees an average of $420,000 per year due to poor word choices and misunderstandings in the workplace (according to Society for Human Resource Management). When used carefully, words can create clarity, connection, and understanding.



How to Improve Your Verbal Communication


1. Be Clear and Concise

Being direct and clear in your speech is critical to ensuring your message isn’t misunderstood. Avoid jargon or overly complex language that might alienate your audience. Stick to the point, and ensure your message is straightforward.


2. Speak with Purpose

Before communicating, ask yourself: What is the purpose of this message? What do I want the listener to take away from this? This ensures that you stay focused and intentional, allowing you to choose the right words to convey your desired message.


3. Practice Active Listening

Great communication isn’t just about what you say—it’s also about listening. When you listen carefully, you understand the other person’s perspective, which helps you choose words that are relevant and impactful.


4. Avoid Filler Words

Words like "um," "like," and "you know" can weaken your message and make you appear uncertain. Practice speaking without using fillers, especially in formal or professional settings, to make your message more powerful and assertive.




The 38%: Tuning Your Voice for Influence

Your tone of voice carries almost five times more weight than the actual words you speak, according to Mehrabian's rule. How you say something often conveys more meaning than the words themselves.



Why Tone Matters in Communication

Tone is powerful because it conveys your emotional state, attitude, and intentions. A flat tone may suggest disinterest, while an enthusiastic tone can signal excitement and engagement. This makes your voice a key tool in influencing how others perceive your message.



How to Improve Your Vocal Delivery


1. Practice Modulating Your Tone

Be mindful of how your tone matches the message you’re delivering. For instance, if you’re excited about something, allow that excitement to come through in your voice. Conversely, if you’re discussing something serious, your tone should reflect the gravity of the topic.


2. Control Your Pitch

Pitch plays a significant role in how people interpret your voice. A higher pitch can indicate nervousness or uncertainty, while a lower pitch often suggests confidence and calm. Practice speaking at a comfortable pitch that conveys confidence without being overly monotone.


3. Pace Your Speech

Speaking too quickly can overwhelm your audience, while speaking too slowly can cause them to lose interest. Find a balanced pace—one that’s easy to follow but not so slow that it becomes tedious.


4. Emphasize Key Words

Vary the volume or intensity on certain words to emphasize important points. This adds rhythm and emphasis to your speech, making your message more engaging and easier to follow.

The 55%: Harnessing the Strength of Non-Verbal Communication

According to Mehrabian, non-verbal communication holds the most weight in shaping how your message is received. Your facial expressions, gestures, posture, and even your eye contact convey a great deal about your emotions, attitudes, and intentions.



The Role of Body Language in Communication

Body language often speaks louder than words. It can reinforce the verbal message or, in some cases, completely contradict it. For instance, if someone says they’re fine but their body language shows discomfort, their words are unlikely to be believed. In professional settings, body language is critical.


"Job seekers with shifty eyes, reluctant smiles or fidgety limbs in an interview may be hurting their chances of landing a job. A new CareerBuilder survey of more than 2,500 hiring managers reveals that failure to make eye contact (67 percent), lack of smile (38 percent) and fidgeting too much (33 percent) would make them less likely to hire someone. The CareerBuilder survey was conducted between May 18 and June 3, 2010." - CareerBuilder


This shows just how influential non-verbal cues are in determining trust and confidence.



How to Improve Your Non-Verbal Communication


1. Maintain Open and Positive Posture

Your posture sends a clear signal about your confidence and engagement. Stand or sit up straight, with shoulders relaxed, and keep your arms uncrossed. This open posture signals that you’re approachable and engaged in the conversation.


2. Use Eye Contact to Build Connection

Maintaining eye contact shows that you’re attentive and trustworthy. Avoiding eye contact can make you appear disinterested or even dishonest. Practice maintaining steady, natural eye contact throughout conversations.


3. Be Aware of Facial Expressions

Your facial expressions are key indicators of your emotions. A simple smile can make a big difference in how you’re perceived. Ensure that your expressions match the message you’re delivering, whether it’s enthusiasm, concern, or empathy.


4. Use Gestures to Complement Speech

Gestures can enhance your verbal message when used appropriately. Avoid excessive gesturing, as it can become distracting. Instead, use natural, purposeful movements to emphasize key points in your message.




Real-World Examples of the 7-38-55 Rule in Action

The 7-38-55 Rule is not just a theoretical framework; it plays out in everyday interactions, from personal conversations to high-stakes business meetings. Here are a few real-world examples where the balance between words, tone, and body language either enhanced or undermined communication.



Business Negotiation with Entrepreneurs, Implementing 7-38-55% Rule with Body Language and Tonality and Words

Example 1: The Impact of Body Language in Negotiations

Imagine you’re in a critical business negotiation. Both parties have agreed on most terms, but there’s a sticking point on pricing. The words you use to make your case might only represent 7% of your overall message. If you’re asking for a discount or trying to get more favorable terms, your body language—such as leaning forward, maintaining eye contact, and using open gestures—can signal confidence and assertiveness, reinforcing the seriousness of your request. On the other hand, if your posture is slouched or you avoid eye contact, your message may come across as uncertain or lacking conviction, even if your words are strong.


Key Takeaway: In high-stakes situations, your body language can often be the deciding factor in whether or not people trust and believe in your message. Aligning confident body language with your words will strengthen your position.

Example 2: How Tone of Voice Affects Leadership

Consider a CEO addressing their team during a challenging time for the company. The words they use might be motivational, but if their tone is flat or lacks enthusiasm, the message will likely fall flat as well. If they speak with conviction, varying their tone to emphasize key points, and pace their speech to build anticipation, the team will feel more inspired and confident in the leader’s vision, even if the circumstances are tough.


Key Takeaway: As a leader, how you deliver your message can either inspire confidence or increase uncertainty. Your tone should reflect the message you want to send—whether it’s rallying your team, providing reassurance, or issuing clear directives.

Example 5: The Role of Emotional Cues in Relationships

In personal relationships, the 7-38-55 Rule can be a game changer. Imagine a conversation between two partners, where one says “I’m fine” but their arms are crossed, their tone is cold, and they avoid eye contact. The words say one thing, but the non-verbal cues tell a completely different story. The other partner will likely pick up on these signals, leading to more confusion or tension.


Key Takeaway: In emotionally charged conversations, non-verbal cues often reveal more than words. Being mindful of your body language and tone can prevent miscommunication and foster better understanding.




Conclusion

Mehrabian's 7-38-55 Rule reveals that only 7% of our communication comes from the words we use, while 93% comes from tone of voice and body language. This breakdown highlights the profound importance of non-verbal elements in shaping how others perceive our message.


Whether you're leading a team, negotiating a deal, or simply having a personal conversation, being aware of how your tone and body language complement or contradict your words is key to effective communication. Communication is about much more than words. It’s about how you say those words and the signals you send with your body. When you align these elements, you not only deliver your message effectively but also build stronger connections with those around you.


So, the next time you engage in a conversation, observe how you communicate beyond words—and watch your influence grow.

Such an important blog, thank you.


People remember more of how we make them feel than what is actually said. So as a leader, it's important that we use our communications to influence others positively.


Those in authority and leadership positions have the potential to effect change in ways that aren't available to others in the same ways. The example that comes to mind is through my work... In safety critical industries, communication features in the causal analysis of approx. 80%* of incidents and accidents (*varying across roles tasks, and industry). Communications is, in its variety of forms, a set of skills that is often taken for granted until something goes wrong and then it's brought under scrutiny. For some…

LOVE this! This is something our Team focusses on a lot for cold calling... the tone, where to pause, when to speed up or slow down and emphasize a word.


We've found that even if we nail the Words we don't get bookings unless we nail the Tone and use our Body Language.


During sales calls this is SUPER important... for example, last week I pitched a Team of lawyers who got another quote 1/3 the cost of ours. IF I hadn't have been certain, used eye contact and leaned in, I would not have won the deal.

Finding the words is only the start as if don't land with the tone and body language, there is very little impact. Having the awareness during the conversation so you can hear thier needs and actuvily adjust tone and body language based on the words but also those you are addressing is a gamechanger.
