Visualise shadow direction and length for any location, date, and time. Enter coordinates to see accurate solar shadow paths and sun position data.
Open Shadow Direction Calculator → free, no sign-inThe direction and length of shadows changes throughout the day depending on the sun's position — which varies by location, date, and time. For architects, photographers, filmmakers, and anyone needing to predict shadow behaviour, knowing this in advance is valuable. The Shadow Direction Calculator visualises shadow direction and length for any location, date, and time.
Photographers choosing the right time of day for a specific lighting condition, architects planning building positioning, filmmakers scouting locations — anyone who needs to understand how the sun will cast shadows at a specific time and place.
No tutorials. No learning curve. Open it and get started.
No server uploads. Generates an interactive visualisation rather than just numbers — you can see the shadow direction and length visually.
Completely free. No trial period. No premium tier for basic functionality. No account required. Use it as often as you need.
One job, done well. Shadow Direction Calculator was built to solve a specific problem cleanly. No feature bloat, no ads, no distractions.
What is azimuth?
Azimuth is the compass direction the sun is in — 0° is north, 90° is east, 180° is south, 270° is west.
What is solar altitude?
The angle of the sun above the horizon. At solar noon it's at its highest; at sunrise/sunset it's 0°.
How do I find my coordinates?
Right-click any location in Google Maps and select the coordinates from the menu.
How does this help photographers?
Know exactly where shadows will fall and when 'golden hour' light angles occur for any location before you arrive.
Does it account for daylight saving?
Enter local time — the tool handles solar calculations based on coordinates.
Free. Instant. No sign-in. Open it and get the job done.
