What Is the Green Line Test? The Viral TikTok Body Language Trend Explained

What Is the Green Line Test?

The Green Line Test (also called Green Line Theory) is a viral body language analysis trend where a straight green line is drawn along each person's spine in a couple photo. The idea is simple: the person standing upright with a vertical line is labeled "STRONG", while the person leaning toward their partner gets a tilted line labeled "WEAK".

The concept suggests that the person leaning in is more emotionally invested or dependent in the relationship, while the one standing straight holds more "power." It became one of the most shared relationship trends on social media.

Where Did the Green Line Test Come From?

The Green Line Theory was first popularized on Twitter in 2020 by a user named Rivelino (also known as Rivelino the Artist). He began posting celebrity couple photos with green lines drawn down each person's torso, claiming the lines revealed hidden relationship dynamics.

The trend truly exploded on TikTok in April 2022 when creator @jackmacbarstool analyzed photos of Kim Kardashian and Pete Davidson. That single video gained over 104 million views, launching the Green Line Test into mainstream culture.

Since then, millions of people have applied the test to their own photos, celebrity couples, and even historical figures.

How Does the Green Line Test Work?

The process is straightforward:

Find a couple photo where both people are standing side by side

Draw a green line along each person's spine/torso

Compare the angles — is one line more tilted than the other?

Label the results — the straighter line = STRONG, the leaning line = WEAK

With our AI-powered Green Line Test tool, this process is automated. Simply upload a couple photo and our AI:

Detects each person's posture

Draws solid green lines on the "strong" person

Draws dashed green lines on the "weak" (leaning) person

Adds STRONG/WEAK labels automatically

What Do the Results Mean?

According to Green Line Theory supporters:

Straight line (STRONG): This person is independent, confident, and holds their own frame in the relationship

Tilted/leaning line (WEAK): This person leans toward their partner, suggesting higher emotional investment or dependence

However, it's important to note that context matters. Someone might lean in because:

They're shorter and adjusting for a photo

They're being affectionate

The photo angle is misleading

They're simply more comfortable being close

Is the Green Line Test Accurate?

The Green Line Test is primarily for entertainment. While body language experts acknowledge that posture can reveal relationship dynamics, most agree that a single photo is insufficient for meaningful analysis.

Dr. Jack Brown, a body language expert, has noted that while postural cues can indicate dominance or submission, the Green Line Test oversimplifies complex human behavior.

That said, it remains an incredibly fun and engaging way to analyze photos — which is why millions continue to use it.
