FREE TOOL: Use Our Free Hyperfocal Distance Calculator for Sharper Landscapes

Struggling to keep everything sharp from foreground to background? That’s a depth-of-field problem. This calculator lets you enter your camera, focal length, aperture, and subject distance to calculate the hyperfocal distance, so you know exactly where to focus to maximise sharpness throughout the scene.

How to use the calculator:

1. Enter your focal length in millimetres.
2. Set the aperture (f-number) you plan to use.
3. Choose your sensor / format to account for circle of confusion.
4. Select result units (meters or feet).
5. Read the minimum focus distance, hyperfocal distance, and maximum focus distance.
6. Use Copy result if you want to paste the values into notes or a shooting plan.

Hyperfocal Distance (quick explainer)

The hyperfocal distance is the closest point you can focus at while still keeping everything from half that distance to infinity acceptably sharp.

• Focus at the hyperfocal distance → foreground to infinity stays sharp.
• Focus closer than hyperfocal → you lose sharpness at infinity.
• Smaller apertures and wider lenses reduce the hyperfocal distance.

This calculator uses standard circle-of-confusion values for each sensor format to give practical, real-world results rather than theoretical extremes.

Quick start

Paste this where you want the calculator to appear (WordPress “Custom HTML” block is fine):

<div class="diyp-hyperfocal-calculator"></div>
<link rel="stylesheet" href="https://www.diyphotography.net/diyptools/diyp-hyperfocal-calc.min.css">
<script src="https://www.diyphotography.net/diyptools/diyp-hyperfocal-calc.min.js" async defer></script>

You can add multiple calculators on a page—just add more <div class="diyp-hyperfocal-calculator"> blocks. All logic runs client-side.

Optional parameters (data-attributes)

Add these to the <div class="diyp-hyperfocal-calculator"> to set defaults or theme.

Attribute	Values	Default	What it does
data-title	Any text	DIYPhotography.net Hyperfocal Distance Calculator	Sets the visible header title.
data-focal	Number in mm (e.g. 50)	50	Sets the starting focal length.
data-aperture	Number (e.g. 8)	8	Sets the starting aperture (f-number).
data-sensor	ff | aps15 | aps16 | mft | mf	ff	Sets the starting sensor/format (affects circle of confusion).
data-units	m | ft	m	Sets the starting units for the result readout.
data-theme	light | dark	light	Chooses the color theme.

Examples

Dark theme, feet:

<div class="diyp-hyperfocal-calculator" data-theme="dark" data-units="ft"></div>

Custom starting values (35mm, f/11, APS-C 1.5×):

<div class="diyp-hyperfocal-calculator" data-focal="35" data-aperture="11" data-sensor="aps15"></div>

Custom title:

<div class="diyp-hyperfocal-calculator" data-title="Acme Lab — Hyperfocal Helper"></div>

Notes for embedders

• What it calculates: hyperfocal distance, plus the near limit when focused at hyperfocal (approximately half the hyperfocal distance) and a far limit of infinity.
• Units: focal length is always in mm. Result units can be meters or feet.
• Sensor values: ff, aps15, aps16, mft, mf map to built-in circle-of-confusion values used by the calculator.
• Rounding: meters are shown to 2 decimals; feet are shown to 1 decimal.
• Styling: CSS is namespaced under .diyp-hyperfocal-calculator to reduce conflicts.
• Multiple instances: the script auto-initialises any .diyp-hyperfocal-calculator it finds on page load.
• Performance: no network calls after the CSS/JS files load; everything runs in the browser.
