How the Hyperfocal Distance Calculator works
Focus at the hyperfocal distance H = f² ÷ (N × c) + f and everything from half of H out to infinity is acceptably sharp. Stopping down shortens H, and a longer lens makes it much longer. Landscape photographers use this to place focus once instead of guessing. Use 0.03 mm for full frame and 0.02 mm for APS-C. Example: A 35 mm lens at f/8 has a hyperfocal distance of 5.14 m, so everything from 2.57 m to infinity is sharp.
Inputs and results
The Hyperfocal Distance Calculator takes 3 inputs and gives 3 results.
What you enter
- Focal length (mm) — starts at 35.
- Aperture (f-number) (f/) — starts at 8.
- Circle of confusion (mm) — starts at 0.03.
What you get
- Hyperfocal distance (m)
- Sharp from (m) to infinity
- Hyperfocal distance (ft)
Example: Hyperfocal Distance Calculator with the starting values
With focal length 35 mm, aperture (f-number) 8 f/ and circle of confusion 0.03 mm, the calculator returns:
| Hyperfocal distance (m) | 5.14 |
|---|---|
| Sharp from (m) to infinity | 2.57 |
| Hyperfocal distance (ft) | 16.9 |
Change any value above and the results update straight away.
Hyperfocal Distance Calculator FAQ
How do I use the Hyperfocal Distance Calculator?
Enter focal length, aperture (f-number) and circle of confusion in the fields, then read hyperfocal distance (m), sharp from (m) to infinity and hyperfocal distance (ft) in the result panel. The answer updates as you type, and you can press Calculate or Enter to refresh it. Use “Copy link” to share your exact numbers with someone else.
What does the Hyperfocal Distance Calculator calculate?
Find the focus distance that keeps everything to infinity sharp. It returns hyperfocal distance (m), sharp from (m) to infinity and hyperfocal distance (ft) from the 3 values you provide.
What values does the Hyperfocal Distance Calculator start with?
It opens with focal length 35 mm, aperture (f-number) 8 f/ and circle of confusion 0.03 mm so you can see a working result straight away. Replace them with your own numbers, or press Reset to return to these starting values.
Is the Hyperfocal Distance Calculator free and private?
Yes. It is free, needs no account, and runs in your browser, so nothing you type is sent to or stored on our servers. See the Privacy Policy for details.
Can I rely on the Hyperfocal Distance Calculator for important decisions?
Treat the result as a well-rounded estimate. Real situations often have details a general calculator cannot know, so confirm important decisions with a qualified professional. See the Disclaimer for more.
