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
For a detailed explanation of every possible outcome, see our Green Line Test results guide.
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. Learn more in our guide to the Green Line Test for wedding photos.
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.
