This tool compares visible lengths and widths with geometric references, including an educational comparison with phi. It also shows visible thirds and facial fifths.
How to use it
- Choose a clear, straight-on photo.
- Follow the guides for the distances being compared.
- Read each definition before comparing numbers.
How to interpret your result
Visible mesh boundaries are not hairline measurements. Phi is a mathematical reference, not an ideal face or a target for treatment.
