Aperture depth of field guide

Aperture and Depth of Field: Which f-stop Should You Use?

Aperture is one of the fastest ways to change depth of field. Wider apertures create more blur; smaller apertures increase the focus range.

Fast answer: Simple DoF Calculator supports apertures from f/0.95 to f/64, so you can compare creative blur and practical sharpness.

How aperture affects sharpness

Changing from f/2 to f/8 can dramatically increase the area that appears sharp, but the exact amount depends on lens focal length, camera format and focus distance.

How to compare f-stops in the app

  1. Select your camera and focal length.
  2. Enter your planned focus distance.
  3. Start with your preferred creative aperture.
  4. Move through nearby f-stops and compare the depth of field result.
  5. Pick the aperture that balances blur, sharpness and exposure.

Common starting points

Try f/1.4 to f/2.8 for shallow portraits, f/5.6 to f/11 for general photography, and f/8 to f/16 for deep landscape focus when light and diffraction allow.
