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.
