Quick Answer

A Depth of Field (DoF) Calculator determines the range of distances in a scene that appear acceptably sharp, based on focal length, aperture, focus distance, sensor size, and circle of confusion (CoC)—like 0.029 mm for a 35mm full-frame sensor.[1][2][3] Our free online tool requires no sign-up, delivering instant results for near/far limits, total DoF, and hyperfocal distance (typically 0.5m to 10m) to perfect your shots.[1][4]

Why You Need a Depth of Field Calculator

Mastering depth of field gives photographers creative control: shallow DoF blurs backgrounds for portrait isolation, while deep DoF keeps landscapes sharp from foreground to infinity.[2][3][6] It's essential for portrait photographers, landscape shooters, astrophotographers, macro enthusiasts, and machine vision engineers needing precise focus ranges (e.g., 0.2m-2m for inspections).[1][3]

Key stats highlight its impact: Doubling CoC (e.g., 1 to 2 pixels) roughly doubles DoF, ideal for vision tasks; pixel pitch sets minimums like 8.6 μm for Canon EOS 7D.[1][2] With over 10 online calculators and apps like PhotoPills serving 50+ million photographers, demand is huge for avoiding trial-and-error.[1][3]

How It Works

Enter your focal length (actual, not 35mm equivalent), aperture (e.g., f/2.8 for shallow DoF, f/11+ for deep), focus distance, sensor size (full-frame or crop), and CoC.[3][4][8] The calculator outputs DoF near/far limits, total depth (e.g., 0.1m to ∞), front/behind subject, and hyperfocal distance using formulas like ( \text{DOF} \approx \frac{2u^{2}Nc}{f^{2}} ).[4][7]

Smaller f-numbers shrink DoF; longer lenses and closer subjects narrow it further.[2][8]

Tips for Best Results

  • Match CoC to use: 0.029 mm for photos, 2 pixels for machine vision (never below 2x pixel pitch).[1][2][3]
  • Use exact sensor/crop factor and test hyperfocal focus for max range from half that distance to infinity.[1][4]
  • Iterate: Widen aperture/shorten focal length for shallower DoF; close aperture/move back for deeper.[2][6]
  • Field-test outputs, as real blur tolerance varies—our free calculator simplifies planning every time.[3][5]
