tool.depth-of-field-calculator Calculator
Calculates near focus limit, far focus limit, and total depth of field from focal length, aperture, subject distance, and sensor format. DOF is inversely proportional to aperture — f/1.4 gives razor-thin DOF; f/16 puts almost everything in focus.
Inputs
Focal Length Mm
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Aperture Fstop
Reference formula or conversion factor shown for context.
Focus Distance M
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Sensor Size Mm
Reference formula or conversion factor shown for context.
Results
depth of field (m)
The computed depth.
near limit (m)
Sample size or count used in the calculation.
far limit (m)
Reference formula or conversion factor shown for context.
hyperfocal distance H (m)
The computed distance or separation.
circle of confusion CoC (mm)
Sample size or count used in the calculation.
larger aperture (lower f)
Reference formula or conversion factor shown for context.
