About the Compatibility Meter
What Is the Compatibility Meter?
The Compatibility Meter is a fun, interactive tool that generates a friendship and work compatibility score between two people. Using a deterministic multi-factor formula, the meter analyses colour preferences, favourite numbers, and eight personality slider dimensions to produce a unique percentage from 1% to 100%. Each score comes with a descriptive label (from “Cosmic Connection” to “Opposite Poles”), a matching emoji, colour-coded circular progress ring, personalised strengths, and actionable tips - all running locally in your browser with no data sent anywhere.
How the Compatibility Meter Works
- Choose Your Mode:Select either “Friendship” or “Work / Team” mode. Friendship mode focuses on personal bonds and social harmony, while work mode reframes results for professional relationships and collaboration styles.
- Enter Names & Preferences: Type in two names, then pick a favourite colour from 10 colour swatches, choose a favourite number (1-9 with personality archetypes), and adjust 8 personality slider dimensions independently for each person - from Introverted/Extroverted and Spontaneous/ Meticulous to Heart-led/Logic-driven and Direct/Diplomatic.
- Calculate & Discover: Click the calculate button to reveal your compatibility percentage on an animated SVG circular progress ring. The deterministic formula ensures the same inputs always produce the same result, making it reliable for comparing different pairings.
Compatibility Categories Explained
- Cosmic Connection (90-100%): A rare and powerful bond with perfect alignment of energies and values.
- Powerhouse Pair (80-89%): An amazing match with strong mutual respect and a highly productive dynamic.
- Strong Bond (70-79%): A solid connection with genuine warmth, trust, and excellent communication.
- Promising Pairing (60-69%): A nice spark with potential to develop into something rewarding.
- Balanced Vibes (50-59%): A neutral-positive connection with common ground and room for growth.
- Developing Dynamic (40-49%): The connection is still developing and needs shared experiences to grow.
- Different Frequencies (30-39%): Operating on different wavelengths with opportunities for learning from differences.
- Work in Progress (20-29%): Needs effort and understanding, but common ground can be found.
- Opposite Poles (1-19%): Very different personalities - but diverse perspectives can build great teams.
Personality Dimensions Explained
The compatibility meter uses 8 personality dimensions to compare two people: Energy Level (Introverted to Extroverted), Planning Style (Spontaneous to Meticulous), Thinking Style (Heart-led to Logic-driven), Sense of Humour(Dry & Subtle to Bold & Loud), Patience Level (Impatient to Very Patient), Social Style (One-on-one to Group-oriented), Adventure Seek (Homebody to Adventurous), and Communication (Direct to Diplomatic). Each person rates themselves independently on a 1-10 scale for each dimension. The formula rewards alignment - smaller differences produce higher scores.
Important Note
The compatibility meter is designed for entertainment and icebreaker purposes only. The algorithm is based on simple preference matching and personality alignment analysis, not validated psychological science. Real friendships, working relationships, and human connections are infinitely more complex than any algorithm can measure. Use the compatibility meter for fun, team building, and sparking conversations - but always trust your real-world experiences and genuine connections over a compatibility score!

Frequently Asked Questions About Compatibility Meter
A compatibility meter is a fun interactive tool that calculates a compatibility percentage between two people based on colour preferences, favourite numbers, and personality slider dimensions. Our compatibility meter uses a deterministic multi-factor formula to generate scores from 1% to 100%, with descriptive labels ranging from "Cosmic Connection" to "Opposite Poles", strengths, and personalised tips.
The compatibility meter is designed for entertainment and icebreaker purposes only. While the algorithm uses multiple factors including colour analysis, number-based compatibility, and personality slider alignment to produce consistent deterministic results, it is not scientifically validated. Real relationships and human connections are far more complex than any algorithm can measure.
Friendship mode focuses on personal compatibility, social harmony, shared values, and bonding - ideal for friends, couples, and social groups. Work / Team mode reframes the results for professional relationships, emphasising collaboration styles, communication preferences, complementary working dynamics, and team synergy. The underlying algorithm is the same, but the result descriptions, tips, and framings are tailored to each context.
Absolutely. The compatibility meter runs entirely in your browser. Names, colour choices, number selections, and personality slider settings are never sent to any server, stored in a database, or tracked. Everything stays completely private on your device. No accounts, no signup, no data collection.
Yes - 100% free with no signup, no account, and no usage limits. Calculate compatibility as many times as you want with any combination of people, completely free forever. There are no premium tiers, hidden charges, or data collection.
The score uses a deterministic formula with three components: colour compatibility (0-15 points) based on similarity of chosen colours, number compatibility (0-15 points) based on numerical difference between favourite numbers, and personality slider alignment (0-40 points) calculated from the average difference across 8 personality dimensions (energy, planning, thinking, humour, patience, social style, adventure, communication). The baseline is 50 points, and the result is clamped between 1-100%. Same inputs always produce the same score.
The compatibility meter measures 8 personality dimensions: Energy Level (Introverted to Extroverted), Planning Style (Spontaneous to Meticulous), Thinking Style (Heart-led to Logic-driven), Sense of Humour (Dry & Subtle to Bold & Loud), Patience Level (Impatient to Very Patient), Social Style (One-on-one to Group-oriented), Adventure Seek (Homebody to Adventurous), and Communication (Direct to Diplomatic). Each person can independently rate themselves on a 1-10 scale for each dimension.
Colour and number preferences are fun, low-pressure data points that add an element of personality insight to the compatibility meter. Colour preferences can hint at aesthetic sensibilities and emotional associations, while favourite numbers (linked to archetypes like Leader, Peacemaker, Creative, etc.) provide a quick personality snapshot. Together they make the results more interesting and personalised - plus they are great conversation starters!
Yes! After calculating your compatibility, you can click the "Share Result" button to copy a formatted result to your clipboard. The share text includes the names, percentage, category label, emoji, and a link to the tool - ready to paste into any chat, social media, or messaging app.
Absolutely! The "Try Again" button resets all inputs so you can test a new pair. You can also manually change the names and preferences to compare different combinations. Since the algorithm is deterministic, running the same two people with the same preferences will always give the same result, making it reliable for side-by-side comparisons.
