Hyperfocal Distance Calculator
Choose a sensor circle of confusion or enter a custom value, then calculate hyperfocal distance in metres or feet.

- Hyperfocal distance
- Near limit
- Far limit
A QUICK WALKTHROUGH
How to use this tool
- Enter a positive focal length and f-number.
- Choose a sensor preset or enter a custom circle of confusion.
- Choose metres or feet and calculate the hyperfocal and near limits.
Formula
Hyperfocal distance H = f²/(N·c) + f. The near limit is H/2 and the far limit is infinity. Focal length and circle of confusion use millimetres.
Circle of confusion presets
Presets provide common approximate values for full-frame, APS-C, Micro Four Thirds, and 1-inch sensors. Use Custom when your output or viewing assumptions require another value.
Local estimate
All inputs are validated and calculated in your browser. This is a planning estimate based on the supplied circle of confusion, not a guarantee of perceived sharpness.
GOOD TO KNOW
Common questions
Why is the far limit infinity?
This calculator follows the requested hyperfocal approximation: once the hyperfocal distance is reached, the far limit is shown as infinity.
Can I use a custom circle of confusion?
Yes. Select Custom and enter a positive finite value in millimetres.
