How We Calculate This

This calculator measures the balance between subject and negative space:

Area Calculation

Subject area = subject width x subject height

Negative space = total image area - subject area

Ratio

Ratio = negative space area / subject area

A ratio of 3:1 or higher indicates strong minimalist composition. A ratio below 1:1 means the subject dominates the frame.
