How to Do the Green Line Test

Want to try the viral Green Line Test on your own photos? Here's everything you need to know — from the manual method to using AI for instant results.

Method 1: AI-Powered (Instant)

The fastest way to do the Green Line Test is with our AI-powered tool:

Go to greenlinetest.app

Sign in with your Google account

Upload a couple photo

Click Analyze and wait a few seconds

Download your result with green lines automatically drawn

The AI detects each person's posture, draws the appropriate green lines (solid for STRONG, dashed for WEAK), and labels everything automatically.

Method 2: Manual (Using Photo Editing)

If you want to do it yourself, you can use any photo editor:

Using Your Phone

Open a couple photo in your phone's photo editor

Use the markup/drawing tool

Select green color

Draw a straight line from each person's head to their hips, following their spine

Compare the angles

Add text labels: "STRONG" and "WEAK"

Using Photoshop or Canva

Import your couple photo

Select the line tool with green color (#00FF00)

Draw a line along each person's spine

Set line thickness to about 4-6px

Use solid line for the straighter person (STRONG)

Use dashed line for the leaning person (WEAK)

Add text labels above each person

Tips for the Best Results

Choose the Right Photo

Standing side by side works best

Full body or waist-up photos give clearer results

Natural poses are more revealing than staged photos

Good lighting helps AI detection accuracy

What to Look For

Shoulder alignment — are both people's shoulders level?

Head tilt — is one person tilting their head toward the other?

Hip position — is one person's hip pushed toward the other?

Feet placement — are both people standing evenly?

Common Green Line Test Results

Both Standing Straight

When both lines are vertical, it suggests a balanced, equal partnership where neither person is overly dependent.

One Person Leaning

The classic result — one person leans in (WEAK) while the other stands upright (STRONG). This is the most common and most shared result.

Both Leaning In

When both people lean toward each other, it can indicate strong mutual attraction and emotional connection — despite what strict Green Line Theory might say.

Both Leaning Away

Rare, but when both lean away from each other, it might suggest emotional distance or simply an awkward photo moment.

Green Line Test for Different Photo Types

Wedding Photos

Wedding photos are popular for the Green Line Test. The formal posing often creates dramatic results, though keep in mind photographers direct the poses.

Candid Photos

Candid shots often provide the most "authentic" results since the couple isn't consciously posing.

Red Carpet Photos

Celebrity red carpet photos are the most commonly analyzed — they're high quality and the subjects are standing naturally.
