Depth of Field Calculator

Calculate depth of field for photography based on lens and aperture settings.

Calculations are based on the traditional circle of confusion (CoC) values. For ultra-high resolution sensors, you may want a more conservative CoC for perfect sharpness.

Overview

Depth of field (DOF) is the range of acceptable sharpness in a photo. Determined by aperture, focal length, subject distance, and sensor size. Wide aperture (f/1.8) creates shallow DOF; narrow aperture (f/16) creates deep DOF.

💡

Pro Tips

Lower f-number = shallower depth of field (more background blur).
Longer focal lengths compress and shallow DOF.
Get closer to subject for shallower DOF.
Full-frame cameras have shallower DOF than crop sensors.

Fun Facts

"f/2.8 on 85mm creates portrait blur (bokeh)."
"Landscape photography typically uses f/8-f/16."
"Hyperfocal distance maximizes sharpness from foreground to infinity."
"Circle of confusion standard: 0.03mm for full-frame."

Formula: DOF depends on aperture, focal length, distance, and circle of confusion
